A message on the topic of climate control devices for the home. What is a climate complex? Steam boilers using wood, sawdust

Modern devices have a number of functions, some of which are typical for all climate control systems on sale. These could be functions such as:

• indoor air purification;
• its hydration;
• air ventilation.

Each climate complex can be equipped with additional functions that may be typical only for some models of complexes:

• air ionization;
• air dehumidification;
• air aromatization.

Other devices go on sale without additional functions. Such devices are much cheaper.

The power of climate control systems ranges from 60 to 90 W. Almost all models are equipped with a clear menu on the display, as well as a control panel, which allows you to regulate the operation of the device even from a distance.

One of the possible advantages of climate control systems is that some of the models are equipped with a function for smoothly regulating the level of air humidity in the room

Advantages of climate control systems compared to similarly functioning devices

Among the advantages of the climate complex compared to other ionizers, purifiers and air coolers, one can highlight the use of ordinary water or ice for cooling, rather than special liquids, some of which are too expensive for every owner of a climate system to afford.

One more positive side the use of climate control systems in everyday life in comparison with other devices that perform similar functions - equipping with a five-stage system or a three-stage air purification system.

Most devices are equipped with a humidity control function. This allows the device to independently monitor whether the air in the room where the climate control system is installed is sufficiently humid. Thanks to the information received, it independently, without the participation of its owner, regulates its operation as required by the air in the room.

At the same time, climate control systems, unlike their analogues, can fully function in autonomous mode, which is the main difference similar devices from conventional air humidifiers, which constantly require intervention from their owners.

Some of the devices are equipped with a function for smoothly adjusting the level of air humidification in the room. Each owner of such a device can adjust the desired level of humidity for himself, thus creating an optimal level of comfort.

In addition to the advantages, climate control systems also have their own disadvantages.

Disadvantages of using climate control systems at home

One of the disadvantages of using climate control systems is the inability to turn off the LCD display. The device may interfere with sleep at night. Some models of complexes have an ill-conceived system for adding water to the device - this is another point that complicates the process of using climate systems in everyday life.

The disadvantage of some models may be too high a cost consumables necessary for the full functioning of climate systems. Not every potential buyer will be able to afford their purchase, even though the device will have high quality production.

A similar disadvantage to conventional air humidifiers is that some models of climate control systems produce too much noise during operation. If during the day you can simply ignore this, then at night using the device may cause some difficulties for its owner, especially if the system is installed in a children's room.

The most popular climate systems

Among potential buyers of climate control systems, devices from the following manufacturers are in demand:

1. Philips

A new product on the market for the sale of climate control systems, a Philips brand device is currently one of the most popular household appliances. There are five stages of air purification. If one of them cannot be completed, the device blocks its operation. The functionality of the complex can be restored only after replacing the filter. The Philips climate control system is characterized by a three-stage humidification setting. Another advantage is that a water softener is already built into the filtration system of the complex.

2. Neoclima

The Neoclima climate system remains no less popular. This complex features three-stage air purification and subsequent humidification. Additional functions of the complex include air ionization, an ozonizer and the presence of a UV lamp.

Types and functions of climate control devices

Pledge comfortable stay a person in any home – a healthy microclimate. Cleanliness, oxygen saturation, and air humidity in the room are of great importance for our well-being. If the climate in the house is too dry, we become susceptible to respiratory diseases. Low oxygen saturation, pollution and even unpleasant odors negatively affect us. Modern climate control equipment will help you easily cope with these problems.

1/ Split system

Of course, the most important device needed to create a comfortable climate in the house is a split system. This is an air conditioner consisting of two units: indoor and outdoor. The outdoor unit contains a compressor, condenser and fan. It can be installed on the cottage wall, roof, balcony, attic or in utility room. The indoor unit is located indoors. It is designed to cool, heat and filter air. The air conditioner units are connected to each other by thin copper tubes, which are laid in the grooves of the walls, behind suspended ceilings or closed with decorative boxes.

If you need to cool a room, you just need to set a command on the control panel. In this case, from the heat exchanger of the external unit one at a time copper tube freon enters the heat exchanger of the indoor unit, and there it is blown by a fan, as a result of which it leaves the indoor unit cold air. The system can also easily warm up too cool air in your home.

Split systems can be not only wall-mounted, but also floor-, ceiling-, column-, duct- and cassette type. But most widespread in country houses We received the wall models that are familiar to us.

2/ Humidifier

A special device – a humidifier – will help maintain the desired level of humidity in the house. It does not require special installation and is capable of working around the clock. confined space without creating noise. Therefore, it can be installed even in the bedroom and children's room.

There are two types of humidifiers: steam and ultrasonic. A steam humidifier works on the principle of hot evaporation. All you need to do is pour water into a special container and plug the humidifier into a power outlet. Using two electrodes, water is heated and converted into steam. For your convenience, the water tank has an indicator of the amount of liquid remaining. The device is very easy to use, and it can be easily transferred from one room to another.

Ultrasonic humidifiers are developed based on high technology. The principle of their operation is to transform water into a water cloud using high-frequency vibrations. Dry air is sucked from the room by a fan, passes through a cloud consisting of microscopic particles of water and air, and is supplied into the room in the form of cold and damp fog. Such humidifiers are the safest to use because they eliminate the possibility of getting burned by hot steam.

3/ Air purifier

An air purifier will help eliminate the problem associated with household air pollution with dust particles. This is a device equipped with a filter system and controlled using remote control. The air entering the device is first pre-cleaned and then supplied to an anti-allergenic filter, where up to 99.95% of microparticles are retained. Having been cleared of impurities, the air enters a carbon filter that can eliminate tobacco smoke, harmful gases and other unpleasant odors and chemical compounds. This way, the air in the room is completely cleansed of impurities and allergens. Therefore, this device is especially recommended for people suffering from allergic diseases.

This type of purifier called “air washer” is especially useful for the home. This device combines the functions of cleansing and moisturizing. The principle of its operation is quite simple. A system of plastic discs lifts water from the reservoir and transforms it into a water bath. The water dust obtained in this way humidifies the air and cleans it of house dust, pollen and other harmful particles. Important advantages of “air washing” - antibacterial protective system, high quality components with long service life, low noise level.

4/ Air ionizer

Scientists' studies prove that the air that passes through air conditioners and air purifiers is “dead.” In such an overly artificial atmosphere, many necessary for a person substances. This can lead to both decreased ability to work and various diseases. You can correct the situation using special device– ionizer. It fills the air with negative ions in concentrations common in forests, mountainous and coastal areas. Your home is cleaned of dust and toxic substances, the harmful effects of radiation from household appliances are neutralized.

There are two groups of ionizers. Large ionizers with a large number of open electrodes are designed for large rooms. They create a powerful flow of electrons and are usually permanently mounted under the ceiling or to the wall. When installing such an ionizer, choose places inaccessible to children. At the same time, the surfaces in the room should be easy to clean, since due to the powerful flow of electrons, the existing dust will settle on the ceiling, walls and furniture. The second group of devices are small portable ionizers designed for an area of ​​no more than 20 square meters. m. The electrodes in them are hidden inside the housing, and the flow of air ions they create is small.

5/ Air flavoring

To create a pleasant, fragrant atmosphere in your home, you should use an air fragrance. Such devices appeared on the market quite recently. The technique works based on natural cold evaporation. Thanks to this, the aroma enters the room without heating and is not distorted. The device is equipped automatic control and a very quiet fan, which helps to distribute the pleasant aroma evenly throughout the room.

The fragrance generates an aerosol based on essential oils secreted by plants. Therefore, using such a device is useful for the prevention and treatment of various diseases. After all, oils converted into an aerosol without heating and loss healing properties remain in the air for a long time, penetrate deeply through the respiratory tract and skin into the human body. It is worth noting that the spraying process occurs quite quickly, and oil consumption is minimal. To treat a room of 20 square meters Only two or three drops of essential oil will be enough. This method of aromatizing a room also helps to disinfect it. Oil microparticles evenly distributed in the air actively destroy viruses and bacteria present in it.

Types of climate control devices

It will not be a secret to anyone that the cleanliness and saturation of pure oxygen in the air that is found indoors plays a huge role in a person’s well-being. If the climate in the house is too dry, then a person develops respiratory diseases. Too humid air promotes the spread of bacteria inside the body. The functions of climate control devices help combat all these factors.

What types of climate control devices are there on the modern market?

• Split system. This is the most common type of climate control devices, which plays an important role in creating an optimal indoor microclimate. It consists of two blocks: internal and external. External unit can be installed on a balcony, roof, wall, attic or utility room. The indoor unit is installed indoors. A split system is designed for heating, cooling and air filtration.
• Humidifier. These types of climate control devices are necessary to maintain the required level humidity. There is no need for special installation and the system can operate even in a confined space without causing discomfort to residents. On modern market There are both steam and ultrasonic humidifier models.
• Air purifier. It will help eliminate problems associated with removing dust particles. The system contains several filters that carry out cleaning, trapping particles harmful to the body. First, the air undergoes normal cleaning, after which it fights allergic particles. The carbon filter removes various gases, tobacco smoke and other unpleasant odors, after which the air is distributed throughout the room.
• Air ionizer. After the air passes through air purifiers and air conditioners, it loses some of the particles needed by humans. This reduces productivity and leads to illness. Functions can correct the situation climate control equipment– ionizer. It imparts ions to the air in concentrations similar to those found in mountains, forests and coastal areas.
• Air flavorings. If you want the room to always have a pleasant atmosphere, you need to use air fragrances. It works on the basis of cold evaporation, due to which pleasant odors enter the air without distorting the temperature.

As you can see, there are several types of climate control equipment, and each of them has a positive effect on human health and general condition. If you want to buy climate control devices, contact representatives of the SPETSOBORONA online store, who will select for you the optimal equipment that will meet your requirements, goals, preferences and financial capabilities. We offer only certified equipment that has passed all relevant tests.

Climate control systems and air washers - why they are needed and how to choose the right model

For normal life activities, work or recreation, comfortable microclimatic conditions should be created in the premises. It's not just about temperature, for installation optimal value which uses air conditioning or heating, depending on the time of year. The composition of the air is no less important. It must have an optimal level of humidity and contain a minimum of dust, bacteria and allergens. This is important for health and performance, as well as the safety of your belongings and decoration. Wooden floors and furniture will not dry out winter period, when the heating is turned on, if the microclimatic balance is maintained.

If we are talking only about air humidity, you can get by with a regular humidifier. But if you want to create a home optimal conditions for life and to get rid of dust and impurities - you should buy a climate control complex or an air washer. The first device is convenient because it combines the functions of a humidifier and air purifier, and some models can also work for heating and cooling. Sinks are good because they provide humidification without the use of additional consumables, by passing air through special humidified drums or hydrofilters. As a result, it is not only moisturized, but also cleansed. In addition, fragrances and ionizers are often built into sinks.

Main characteristics of equipment for creating a comfortable microclimate

The choice of a climate control system or sink begins with determining the range of tasks that will be solved using the device and selecting a model that has all the necessary functions. Indeed, in some cases it is enough to humidify the air and remove some dust from it. In others, you have to fight unpleasant odors, pet hair and ensure maximum removal of allergens such as pollen from the air.

Therefore, when choosing, you need to pay attention to the following characteristics:

• type and capabilities of filters used;
• device power and volume of purified air;
• water tank volume;
• noise level;
• presence of an ionizer and additional functions;
• Possibility of operation in heating and cooling modes.

Deciding on a set of filters

In order to understand what filters are needed in the purchased complex or sink, you need to understand functional purpose each of them.

Filter in air washer

In an air washer, the filter is a curtain of water droplets or a thin film created by rotating disks lowered into a reservoir of liquid. This system successfully copes with humidification, as well as removing large dust particles. Collecting moisture, they become heavier and fall or settle on the drums when air is passed through. The advantage of such a system is that it does not require the purchase of additional filters. You just need to periodically clean the sink. However, such a system does not cope with all types of contaminants and does not provide the same high-quality air purification as a specialized filter. If you live in a less environmentally friendly area, such as near a heavily used road, you need more efficient filters.

To improve the quality of air purification, an ionizer is installed in the sink. With its help, negative ions are created that saturate the air. They are believed to have positive influence on immune system, promote memory activation and attentiveness.

Ionization is carried out before or after air enters the water filter. Pre-ionization provides better dust removal, but there are fewer negative ions in the air passing through the sink, since they are mostly destroyed during contact with water.

Climate complex filters

There are more filters and units for air purification in climate control systems. In addition to the ionizer, they are equipped with:

• ultraviolet lamps;
• carbon filters;
• HERA filters;
• photocatalytic and electrostatic filters.

HERA filters are used to clean the air from pollen, small dust particles and other allergens.

The carbon filter ensures the removal of harmful gases, including carbon monoxide, formaldehyde and tobacco smoke, and also eliminates unpleasant odors.

The photocatalytic filter provides cleaning from harmful organic and inorganic impurities, viruses and bacteria, as well as mold spores. This type of filter is good because it does not accumulate captured pollutants, but decomposes them, forming harmless substances. The optimal result of this type of filter is achieved when used in conjunction with an ultraviolet lamp.

Most climate control systems use the following cleaning and humidification scheme:

• air enters the complex through a HEPA filter, which precipitates dust, pollen and small particles;
• Then it is driven through an evaporator, in which it is enriched with moisture. If there is antibacterial impregnation, then it additionally destroys harmful microorganisms that are not retained by the HEPA filter;
• photocatalytic filter eliminates unpleasant odors;
• The fragrance and ionizer saturate the air with pleasant aromas and beneficial negative ions.

Serviced area and air exchange

When purchasing a climate control system or a sink, you need to pay attention to the area of ​​the room the device is designed for. Manufacturers indicate in the characteristics of the device the power and area for which the device is designed. The power of air washers and climate control systems is usually low. The main energy consumer in such devices is the fan, and they try to make it as silent as possible and it consumes little energy. On average, the power of climate control systems ranges from 15 to 90 W. To service premises up to 30 meters in area, Watt devices are sufficient.

The exception is devices that not only purify and humidify the air, but are also used as heaters. An electric heater requires a lot of power to operate. Therefore, such devices consume an average of 1700 - 2000 W.

The area of ​​the room for which the device is designed is a very important characteristic that allows you to select best option for your premises. You should not buy a device designed for small areas to serve large rooms. He will not cope with his tasks.

But buying a complex that is too powerful, in the hope that it will serve several rooms at once, is also wrong. The fact is that the doorways are not large enough to provide a high level of air exchange and the desired effect will not be achieved. Therefore, the device is moved from room to room or purchased equipment designed for the required area for all rooms that need cleaning and humidification. The second option is more correct, especially if you are buying a sink. When moving it from room to room, you may encounter the fact that maintaining the optimal level of humidity is not ensured. The fact is that the washing principle is based on the natural evaporation of water, and this process is not fast. Therefore, if you move it from one room to another, the humidity balance in one room will be disrupted, but in the second it will not improve.

To achieve optimal microclimatic conditions, the rate of maximum air exchange is important. It should be such that it ensures that the air in the room passes through the device at least two to three times within an hour. In this case, it is updated at the optimal speed. The maximum air exchange rate is generally in the range from 120 to 450 cubic meters per hour.

For air washing great value has a combination of performance and water tank volume. Productivity shows how much water in grams passes from the device into the air in the room per hour. On average it ranges from 200 to 500 g/hour. It is believed that in this case the optimal volume of the water tank is from 5 to 7 liters. If it is less, you will have to add water often.

Additional features

Climate control systems and air washers are equipped nearby useful functions, which increase the cost of devices, but make their use more comfortable. Worth noting:

The presence of a flavoring container will delight fans of aromatherapy. Add to this container essential oils. When you turn on the device, pleasant odors spread throughout the room, which have a positive effect on nervous system and general well-being. And if you use pine oils, they will serve as an additional cleaning from microbes. This is ensured by phytoncides contained in coniferous wood and in oil too.

The presence of a humidity and air purity control system allows you to fully automate the operation of the climate control system. The hygrostat will turn on the humidification system when the humidity drops below the optimal level, and air purity control will allow you not to run the device in vain if the air has been cleaned to an acceptable level.

The device control system can be mechanical - all control commands are given using switches, as well as electronic or sensory. Mechanical control is used in devices with a minimum set of functions. Modern systems are equipped with electronic controls and touch buttons. In addition, such devices can be equipped with remote controls, allowing you to control sinks and climate control systems with maximum convenience.

Heating and cooling functions are also optional. Heating devices have an additional built-in heater. Evaporation is used for cooling cold water. For this purpose, refrigeration elements pre-cooled in the freezer are placed in a tray with liquid. This method is environmentally friendly, but not as effective as a standard air conditioner (split system).

ROOM CLIMATE UNITS

To create a favorable regulated microclimate in buildings with a multi-room layout, providing space heating in winter, air cooling in summer and year-round ventilation, it is rational to use room climate control devices, since the implementation of central systems is associated with design and operational difficulties.

In climate control devices, it is possible to humidify or dry the air, clean it from dust and perfume it. A mandatory requirement for climate control devices is the supply fresh air and heating it in the winter, for air conditioners, in addition, cooling the air in the summer.

The efficiency of the climatic device is t|P1, . combining heating (cooling) functions with ventilation, is determined by the formula where (pr is the temperature of the supply air;

In winter, efficiency increases with increasing ^ir (which is limited by hygienic standards) and /cm. As the fCM temperature increases, the recirculation air flow rate increases and the efficiency increases. So at 100% recirculation

Je I U [ і р == TJcHCT.

In central air conditioning systems, to increase efficiency, i.e., reduce heat and cold consumption, air recirculation is usually used, which is associated with the installation of additional channels. In climate control units, air is recirculated directly in the rooms served. Devices are most often installed near external walls. In climate control units, the functions of heating in winter and cooling in summer are performed by one heat exchanger (with the exception of four-pipe systems). The heat and coolant is water supplied to the heat exchangers of the devices through a common piping system.

Schematic diagrams a number of climatic devices are shown in Fig. 10.

Heating and ventilation devices heat the air and, if necessary, humidify it. In heating and ventilation devices with artificial impulse II air conditioners, air movement is carried out by a fan or due to the kinetic energy of primary air from a central unit.

In non-autonomous air conditioners with centralized heat and cold supply, air movement is carried out by low-noise centrifugal axial fans.

In ejection closers, the outside air (primary) processed in the central air conditioner, leaving the ejection nozzles at high speed, sucks in the room recirculation air.

Fan closer air conditioners perform local processing and movement of air, which is mixed with primary air from the central system and enters the room. By design features climatic window sill devices are divided into frameless, frame and wall-mounted. Device housings are made of metal, plastics and other materials. IN frame structure lungs can be attached to the corners sheet materials or even heat and sound insulating fabric. Frameless and frame devices are manufactured as a single unit and, upon installation of the heat exchanger inlet, are threaded to the supply

In systems with ejection and fan coils, humidification is carried out in the central

and return connections from the riser. The wall-mounted design of the devices is less industrial since it requires fastening the heat exchanger, parts and installation of the casing to the outer wall at the construction site.

The intake of outside air can be carried out directly through openings in the external walls or using suction air intake vertical shafts to each device.

Outside air can also be initially processed in a central air conditioner and then pumped to air conditioning units for secondary treatment.

A simple one is to directly connect the air conditioner to the air intake hole, which is provided during the manufacture of external wall panels.

The disadvantages of such a connection include the difficulty of sealing the air conditioner pipe to the wall of the air intake opening. Large quantity outdoor air intake openings with grilles may be undesirable from an architectural point of view. The influx of outside air here depends on wind and heat pressure. At centralized supply air supply to room air conditioners, the conditions for purifying outdoor air are significantly improved, the possibility of noise from the street entering through the air intake opening and overturning the circulation inside the room is prevented.

With centralized processing of outdoor air, it is possible to regulate humidity.

To supply climate control devices with cold and hot water rational use of the centralized heat and cold supply network from the lithium bromide absorption machine.

One of the simplest and most economical cooling methods for areas with dry, hot climates is evaporative cooling of water in a flow of dry air; Water cooled as a result of evaporation serves as a source of air cooling. The limit of evaporative cooling is the wet bulb temperature of the air. In direct evaporative cooling, outside air and water come into direct contact in an adiabatic process. Air-water contact can occur in central irrigation nozzle chambers for central systems and in the irrigated layer in local installations. In both cases, work occurs on recirculated water fed from the water supply. With direct evaporative cooling, simultaneously with a decrease in air temperature, an increase in its moisture content occurs. When supplying air with significant moisture content is undesirable, indirect evaporative cooling can be used, in which the main air flow is cooled

It is fixed in a surface heat exchanger. Significantly greater air cooling efficiency can be obtained in installations with indirect and direct evaporative cooling (Fig. 11).

The outside air in a neutral air conditioner is purified in filter 5 and supplied to heater 1, where it is cooled at a constant moisture content. The heater 1 of the central air conditioner and the room injection closers receive water that has undergone evaporative cooling in an auxiliary form.

chamber 7. Since the water temperature is always higher than the dew point temperature of the outside air, there will be no condensation of water vapor from the air. After cooling in the heater, the outside air enters the nozzle irrigation chamber. The wet bulb temperature of the pre-cooled outdoor air will be lower and therefore achieves greater evaporative cooling of the air by the recirculated water. After this, the primary air is supplied to the room ejection air conditioners.

In table 14 shows the temperatures of the supply primary air leaving after treatment. These temperatures are obtained by heating the water in the heat exchanger by 3°C at a minimum

a small temperature difference of 3° between the temperature of the water leaving the heat exchanger and the cooled air, with further humidification of the air in the adiabatic chamber to a relative humidity of 90%.

Since heat exchangers are usually selected according to summer mode, we will determine the maximum temperature hot water, which must be supplied to climate control devices in winter. The amount of heat given off by the air conditioner to the room, assuming that the temperature of the working fluids changes according to a linear law for the heating mode QHarp and cooling mode QoX’.l t is determined from the formulas:

where K heat and Ko:

At a constant air capacity of the climate control unit kg/h and at a constant flow of water (passing through the heat exchanger) in the heat and cold supply system, the values ​​of d7 air and d7B0DY for winter and summer modes are the same. Cooling and heating loads are related by proportionality coefficient b

When calculated using formula (61) /”ax = 75.5°C.

In fact, the temperature of the coolant in all cases for buildings equipped with room climate control devices selected according to the summer regime will not exceed 70°C. Thus, systems equipped with climate control devices can be connected to low-potential heat supply sources.

To humidify the air in climate control devices, various types of humidifiers can be used. Devices can be equipped with simple humidifiers in the form of open evaporation surfaces. The energy for spraying water can be water pressure, a special individual drive, or an electric fan motor.

Of interest are atomizers that use energy compressed air pneumatic automatic control system. Perfumerization of air in climate control devices can be done together with humidification. There is evidence that the evaporation of triethylene glycol in the air reduces the transmission of infections. It is believed that when ethylene glycol comes into contact with dust particles, the released latent heat causes an instant rise in temperature and kills the microbes.

To reduce metal consumption compared to radiators, it is rational to make heat exchangers of devices from finned surfaces. A comparison of the weight of 1 m2 of the heating surface of the radiator and heat exchangers made of various finned tubes is given in table. 15.

Aluminum tube with knurled - 1 MP ribs, 0

Weight in kg 1 .and 2 heating surfaces

The economic efficiency of heat exchangers is usually determined by the thermal stress of the metal. With a calculated temperature difference of 64.5°C, the thermal stress of the metal for cast iron radiators type M-140 is 63 kJ, for concrete heating panels with coils using thin-walled electrically welded pipes - 346 kJ, and for devices with heat exchangers using steel finned tubes - 630 kJ. The analysis shows significant advantages of aluminum heat exchangers with rolled fins.

In the operation of surface heat exchangers in summer, two modes are observed - “dry”, without condensation, and “wet” with condensation of vapors on the surface.

In dry mode, the initial temperature of the cooling water supplied to the air conditioner heat exchanger should be equal to or slightly higher than the dew point temperature of the air processed in the air conditioner.

In humid mode, not only the sensible heat from the air is removed, but also its moisture content is reduced. To do this, the initial temperature of the water supplied to the surface air cooler must be lower than the dew point temperature of the air being processed. Heat transfer is associated with mass transfer and requires the installation of condensate collection trays and a drainage pipeline.

Air purification in climate control units can be done using sponge air filters made of polyurethane foam (PPU)*. To enable the use of polyurethane foam in air filters, it is subjected to special processing in order to increase its air permeability. Regeneration of the material is carried out by washing it.

To ensure silent operation of devices with a fan, it is necessary to use low noise fans, low noise single-phase micromotors.

In table 16 and 17 are given technical specifications axial fans and single-phase microelectric motors for voltages of 110 or 220 V, which can be used for climate control devices before the industrial production of special capacitor electric motors of the DVE series.

To maintain a constant temperature in the rooms where room climate control units are installed, it is advisable to provide automatic control. The use of automatic control provides savings in heat consumption of up to 20-25%. Schematic flow diagrams of electrical automatic control are shown in Fig. 12. In Fig. 12, and the diagram is shown

Schematic diagrams of automatic control of climate control devices: a-two-position control by a valve for heat and cold; b-two-position fan control; c-two-position electrical control of water supply by a valve with automatic mode switching; g-two-position regulation by the air conditioner fan and the outside air valve; d-regulation of air temperature by controlling a three-way valve on a heat-cooling station.

two-position regulation by the valve on the heat-cooling body. The switch (P) switches on the automatic control mode for winter or summer time. The command body is the temperature sensor (TS). When the temperature increases or decreases relative to the setting on the sensor, it

The pulse is transmitted through an intermediate relay (РҐІ) to a two-position actuator DR, which opens or closes the passage of heat or coolant. To protect the heat exchanger from freezing, the valve should not be completely closed. A similar on-off fan control circuit (Fig. 12, b) - a pulse from the temperature sensor (DT) through an intermediate relay (RP) turns on, switches the rotation speed or stops the fan. This is the simplest and convenient scheme for regulation of non-autonomous air conditioners.

A diagram of a two-position electrical control of water supply by a valve, with automatic switching from winter to summer mode and vice versa, is presented on the RPS. 12, c. This scheme can be used if strict adherence to air temperature is necessary during the transition period. By turning the manual switch (II) through the intermediate relay (RP), the fan is turned on and the valve is regulated by the temperature sensor (DTi). When the fan is turned off, the water supply to the heat exchanger stops, which prevents moisture condensation in the summer when the air conditioner is turned off. The DTg temperature sensor is designed to switch the DTi sensor from heating to cooling mode when the return water temperature changes. The diagram of two-position control of the air conditioner fan and the outside air valve is shown in the diagram. 12, g. When the fan starts, the valve automatically opens, and when it stops, it closes. Proportional control of air temperature by controlling a three-way valve on the heat-cooling body is shown in Fig. 12, d. The command body is a proportional temperature sensor of the TPD type (or TPK). Through a balanced relay (BR), the pulse is transmitted to the actuator (AM).

If there is a compressed air network for humidification or other needs, you can use pneumatic and electric-pneumatic automatic control circuits.

Climate control units are usually installed near external walls under windows, while in winter time the supply air well retains the cold air flow falling from the windows.

Installation of climate control units near external walls with lower supply air distribution is especially desirable for rooms with large surfaces of external fencing or glazing. However, with such air distribution, the heat load of the room increases due to blowing on the inner surface of the external fences and. consequently, changes in its temperature and an increase in the heat transfer coefficient. Window air distribution is particularly effective when

double glazing and the use of sun protection devices in summer.

Let's consider the relationships between the supply air temperature, the circulation rate and the heat load of the room. The heat transfer of the climate control device in the room (recirculation mode) is equal to

In Fig. Figure 13 shows the graphical dependence of equation (65) for winter (at tu = 18“C) and summer mode (at tB = 25С).

Since the cooling load is predominant, the limits within which cooling is economical can be seen from Fig. 13, b. Excessive increase<7охл показывает, что уже при разработ­ке проекта необходимо предусмотреть мероприятия для сниже­ния нагрузки охлаждения.

Graph of Fig. 13 when installing devices under windows, it is limited by the maximum supply air temperature allowed by the temperature difference between supply and room air and the circulation rate.’

The distribution of supply air in a room depends on the Archimedes criterion, which is the ratio between the lifting layer caused by a change in density and the inertial force of a unit volume of moving fluid.

where g is the acceleration of gravity, .11/sec2;

d3 - equivalent (in area) diameter of the live cross-section of the inlet opening, .i;

1’0 - air speed at the exit from the inlet, m/sec;

J/p is the operating temperature difference;

Hocr - ambient air temperature, degrees K.

The Archimedes criterion is the only criterion that determines the distortion of the jet axis caused by gravitational forces. Assuming that for the axis of a non-isothermal jet the law of change in maximum speed and temperature is the same as for an isothermal one according to I. A. Shepelev, the maximum relative ordinate of a scab of cold air directed vertically upward is

where a is the coefficient of the turbulent structure of the strings.

Below are examples of calculating air strings when supplying air to climate control devices in the summer.

In Fig. 15-17 show the non-autonomous room air conditioners we developed. The air conditioner housings are made of particle boards, the grilles for recirculation and supply air are made of plastic. The front wall of the air conditioner is removable (retractable, Fig. 17 or liftable, Fig. 16).

The graphical dependence for determining the heat transfer coefficient K wtm2 of aluminum and steel heat exchangers of air conditioners depending on the water flow rate C, obtained experimentally, is shown in Fig. 18. Tests were carried out at an average coolant temperature of 10°C, with a water speed in the heat exchanger above 0.6-0.7 m/sec.

The heat transfer coefficient remained almost unchanged, which is confirmed by the study of O. A. Kokorin.

The results of aerodynamic tests of air conditioners in laboratory conditions are given in Table. 20 її in natural conditions - in table. 21.

The air flow capacity of air conditioners ranges from 12° to 335 m3/h (on the suction side at = = 20°C). The performance of the air conditioner with an increase in the number of heat exchanger rows from one to two is reduced by 12%.

The ratio of recirculation and outside air is in the range of 2.1: 1 to 2.57: 1, i.e. outside air comes from 32 to 28% of the total air conditioner performance. The amount of outside air ranges from 37 to 100 m3/h, i.e. it provides a sanitary standard for rooms containing from 1 to 4-5 people. The results of tests under natural conditions showed that the overall air conditioner performance almost does not change depending on the position of the control valve in the outside air.

During tests at air speed in the outside air intake opening c = 0.67-0.79 m/sec, the amount of incoming outside air increased by 10-50% compared to tests in laboratory conditions.

When the control valve is closed, due to its loose connection to the outside air intake box, 5.5-10% of the total air production passes through.

Opening the control valve to 50% has little effect on the ratio of recirculation to outside air. The speed of supply air discharge along the length of the supply grille is uneven. At the center of the air conditioner, the discharge speed is 20% less than at the edges of the supply grille.

The noise level when the air conditioner is on (the room's own noise) is 42 dB. The overall noise level in the room when the air conditioner is operating ranges from 53-59 dB. The excess of permissible noise in the daytime (normative curve PS-35) in the low frequency range is 5-12 dB and in the high frequency range

It is necessary to take all noise reduction measures, including mounting electric motors on flexible shock absorbers. It is also advisable to use single-phase capacitor electric motors of the ABE type. Electric motors of this type provide a noise level within 48-50 dB (in a closed version on plain bearings).

Tests have shown that opening and closing the outside air intake valve has a slight (up to 2 dB) and irregular effect on the noise level in the room.

In Fig. Figure 20 shows the dependence of the resistance of air conditioner heat exchangers at various water flow rates.

Prototypes of the described air conditioners with automation, made to order, cost 120 rubles.

1 piece, in serial production their cost will be 50-60 rubles.

Preliminary calculations show that the total costs of an air conditioning system with non-autonomous window sill air conditioners in mass production without taking into account the cost of refrigeration devices will be 30-50% higher than the costs of a heating system with radiators.

Considering that the air conditioning system simultaneously performs the functions of fresh air ventilation, we can assume that the costs of constructing an air conditioning system in a number of buildings will be the same as those for constructing a heating and fresh ventilation system (without taking into account the cost of refrigeration devices).

No matter how carefully we plan our home, it can still easily end up being less than ideal in terms of climate and temperature conditions. This problem can be corrected using various climate control equipment.

What types of climate control equipment can make our home comfortable?

1. Air conditioners - stationary and mobile.

Stationary split systems or floor-mounted mobile air conditioners are a powerful tool for regulating indoor climate conditions. This technique will allow the inhabitants of the house to feel comfortable at any time of the year, be it cold or hot outside the windows. Air conditioners allow you to regulate the room temperature down to one degree. They are also able to quickly ventilate the home.

Stationary air conditioners are quite expensive both to purchase and to install. Their installation requires significant costs. But at the same time, if we compare this type of equipment with mobile floor-standing analogues, they work much quieter.

Floor-mounted portable air conditioners produce a lot of noise during operation. But their advantage is that when they are not needed, they can easily be put away in the pantry.

2. Air purifiers and humidifiers.

Air humidity is one of the basic parameters characterizing the home microclimate. Typically, humidity should be between 40 and 60 percent. With these indicators, a person feels comfortable. Moreover, insufficiently humidified air serves as an excellent environment for the development of various viruses, including those dangerous to humans. Indoor flowers do not grow well in dry air.

A humidifier is used to humidify room air. Their original appearance, affordability and reliability make these devices very popular. It is enough to pour ordinary tap water into such a humidifier and turn it on, and a comfortable level of humidity in the room is ensured.

Air purifiers make the atmosphere free of allergenic particles. In parallel with purification, most of these devices have an atmosphere ionization function, which makes living in such a house safe for asthmatics and people suffering from viral diseases.

3. Water heaters.

Hot water seems so familiar until you experience interruptions. It immediately becomes clear what a big role hot water plays. That's why having an independent hot water supply means so much. Storage or flow-type water heaters cope well with this problem, supplying you with hot water at any necessary time at fairly low energy costs.

4. Heaters.

In our climate, an air heater in a home is not a luxury item, but a necessity. Today, oil heaters and dangerous stoves are becoming a thing of the past. They are being replaced by safe and effective equipment.

An electric convector is an excellent example of a new generation of heating technology. They are able to maintain a stable temperature in the room, moreover, when turned on, they heat the air very quickly.

Another effective type of heating technology is infrared heaters. They are interesting because they heat not air, but furniture and interior items, and are therefore more economical - the temperature with this heating method drops much more slowly.

5. Electric fireplaces.

An interesting solution for maintaining heat in a room is electric or biofireplaces. Modern models imitate a living flame so skillfully that you can often even be mistaken that this is an electric imitation or a real fireplace.

Environmentally friendly biofireplaces allow you to use various safe and environmentally friendly types of fuel for heating, keeping the indoor air clean and significantly saving heating costs.

We try to choose the best for ourselves and our family. Healthy food, clean water, orthopedic mattresses. At the same time, we rarely think about what exactly we have to breathe. Meanwhile, our health directly depends on air quality. Of course, we are unable to change the overall environmental situation, but creating the most comfortable climate in our own home is quite possible. And here modern technologies come to our aid. We will talk about the main devices that can improve the air quality in our home.

Humidifiers

The optimal humidity in the house should be 60%. This coefficient can be measured with a hygrometer, which is sold in a pharmacy. Lack of moisture in the air contributes to the accumulation of static electricity and prevents the settling of indoor dust. When humidity is less than 30%, the mucous membrane of the human respiratory system begins to dry out, which increases susceptibility to respiratory infections. Modern air humidifiers help solve this problem. There are several types of humidifiers. Let's talk about the four main ones.

1. Traditional humidifiers provide natural humidification. In addition, they do not require additional costs for replacement parts, and are the most economical and easiest to operate. And some models can even be used for aromatherapy. Their only drawback is the need to periodically replace the cartridge.

2. Ultrasonic air humidifiers have an automatic shut-off/on function and a highly efficient cartridge. They operate silently, and the humidification efficiency is quite high. In addition to all other advantages, they are also economical. Of the minuses: frequent cartridge changes, demineralized (softened) water is required.

3. Air washers - humidifiers with air purification function. These devices humidify and purify the air at the same time. By purchasing this model, you will avoid additional costs for filters. And in operation they are absolutely silent. Minus: limiting air humidification to 60%.

4. Steam humidifiers. These models have more disadvantages: there is a risk of steam burn (air outlet temperature is 60 0C), high energy consumption, not all models have a humidification sensor. But there is only one plus: some models have inhaler nozzles.

Air dryers

Dehumidifiers are necessary in rooms with high humidity. For example, in the bathroom, in the kitchen, in the basement. Increased air humidity can lead to quite devastating consequences: premature destruction of the load-bearing elements of the building, corrosion processes in metals, the formation of fungus, mold, etc.

There are two types of household dehumidifiers.

1. Adsorption dryers. The main part is occupied by adsorption material, which absorbs excess moisture. The disadvantage of this model is the need to frequently replace cassettes. In addition, the humidity in cabinets and other closed areas remains the same.

2. Compressor dryers. The basic principle of operation of such a dehumidifier is to cool humid air until condensation forms. The condensate then drains and is drained. A compressor dryer has high power and can handle large volumes of air, but it operates with a higher noise level, consumes electricity and has larger dimensions than adsorption dryers.

Air ozonizer

The ozonator in the house performs two main functions: health-improving and domestic.

By inhaling ozone (within acceptable limits), you improve your overall health. In addition, ozone kills viruses and bacteria, which means that it is necessary for the prevention of various seasonal diseases transmitted by airborne droplets.

As for the household benefits of ozone, it purifies the air from smoke, mold, bacteria, dust mites, pollen, odors generated during cooking, “aromas” of pets and chemicals, and removes mustiness. It can add a fresh smell to shoes, clothes, and bed linen.

Most often, ozonizers have two operating modes. Normal - when ozone has a stimulating effect on the human body, increases immunity, resistance to toxic substances, increases the hemoglobin content in the blood, and normalizes blood pressure. And reinforced - for quick and effective air purification, which must be used in an empty room, since breathing such ozonated air is unsafe.

Ionizers

In the natural environment, the source of ionized oxygen is plants, mainly coniferous trees (pine, spruce). And in apartments it is necessary to use ionizers. Below are some recommendations for choosing.

For particularly sensitive people, asthmatics, allergy sufferers and children's rooms, it is better to choose a salt lamp as an ionizer - these are natural ionizers with very soft ionization and do not emit ozone at all.

If there is a lot of dust in the room, there are people with allergies or small children in the family, you should choose an air purifier with a HEPA filter that has a built-in air ionizer. When choosing this device, keep in mind that there are ionizers that work on the principle of ionic wind - causing air circulation due to a high electrical charge, as well as ionizers with a fan. The big advantage of the former is almost silent operation and low cost. But for some, their disadvantage may be a fairly large ozone output.

According to doctors, 90% of colds and infectious diseases are transmitted indoors! In the open air, dust and microbes are destroyed, and indoors all conditions contribute to their proliferation. And if modern technologies allow us to solve this problem, then why not take advantage of it? After all, health is the most valuable thing we have. Be healthy and breathe only clean air!

Elevated temperatures, poorly ventilated rooms, decreased productivity of staff in the summer heat - these are quite common problems that large enterprises and administrative institutions have to face. They can all be solved by installing an air conditioning system. It is usually designed and installed during the construction of the facility, but it is also possible to install climate control equipment on an already constructed and functioning facility. If you need an air conditioning system and want to enjoy fresh and cool air, then you should contact specialists who can choose the most suitable model for your specific room.

First of all, if you want to buy climate control equipment, you need to establish specifically for which room it will be used. Because for a small office one type of air conditioner will be needed, and for a more serious large industrial organization a completely different one. The second question that you need to decide is to decide what type of climate control equipment you need.

Types of climate control equipment:

• wall-mounted split system - this air conditioner is suitable for small offices. Its advantages are: compactness, noiselessness, small size and many built-in functions. It is also possible, if necessary, to install additional systems to regulate air and flow filters;
• multi-split system - this equipment consists of internal units that are connected to one installed on the outside. The system is designed to cool several rooms at once, with each indoor unit having its own control;
• mobile air conditioner - such climate control equipment will work like a fan in hot weather, and like a heater during winter frosts. Does not require special installation. Perfect for the office of a director or manager. It is good to purchase such climate control equipment when it is not possible to install another system;
• Window air conditioner - installed in the window opening. Its advantages include: significant reliability, ease of use and low cost. Disadvantages are window darkening and noise during operation;
• Duct air conditioner is a semi-industrial unit. Suitable for large areas. The device can easily cool several rooms at the same time.
