Channel air dryers is a functional drying equipment for pools that provide comfort in any weather. As a rule, installed in a special ventilation chamber
Increased air humidity in a modern country house- headache source for any homeowner. Because of it, it is premature to determine the decoration of the premises, the furniture, the fungal mold appears, there is unpleasant odors, winter - fogging and covered with incomplete glazed surfaces ... To combat excessive humidity, use air dryers
For all occasions
You probably noticed that for drying room on a summer day, it is often enough to simply open the windows and arrange a draft, with the result that all the excess moisture will quickly disappear. However, this technique does not work everywhere and not always. Salmon ventilation is impossible, for example, in the bathrooms, in the storage rooms, in the dead-end rooms of the basements. Do not open the window and for the speedy drying just passed on the wallpaper walls, the whole work will go to the pump. In winter, ventilation is associated with large energy losses - along with moisture, warmth and warmth, and the dwelling is laid. Well, when pouring rains and the relative humidity of the outdoor air is close to 90-95%, even intensive ventilation of the country house is almost ineffective.Air dryers are just used in cases where it is impossible to ventilate the room or this measure does not give the expected result.
So, domestic dryers can be used resolutely in any room of a country house, where the humidity is higher than the norm. Lowering moisture, these devices exclude the possibility of accumulating condensate on the surfaces of the ceiling and walls, and therefore their damage to the color of the fabrics, wallpaper, cracking of paint IT.D. Such desiccant forces to prevent the appearance of fungus and mold-frequent guests of poor ventilated bathrooms, shower, laundry IT.P. Fighting the fungus after its turmoration of the material is sometimes not so easy, it may be necessary to use toxic chemical preparations, and in some cases, even re-laying tiles.
The intense time of the year housewives often complain that things after washing will not dry for a long time. If you put the dryer next to the linen dryer, the wet textile will dry in just a few hours.
We can remove moisture from the surface of the musical instruments, the lenses of photo and film cameras, carpeting, not allowing rust on metal objects. Put devices and inside large book and wardrobes in the rain period. Deposit, where the reserves of the provisionant are contained, they will protect the bulk food, sugar, salt, flour. It is much better to store washing powders, medicines, as well as building materials for which the manufacturer has a certain level of relative humidity of air installed in the "dried" room.
Absolutely regarding
Air humidity is determined by the amount of water vapor present in it. The absolute humidity is called the density of water vapor contained in the air at a given temperature, expressed in grams on 1m3. To estimate the degree of dryness or humidity of the air, this indicator is little suitable, since at the same value (for example, 60%) air depending on the temperature may be dry or wet. After all, the higher the air temperature, the more water vapors can contain. The maximum amount of water vapor saturated with air at a specific temperature is called maximum humidity. The true idea of the degree of air humidity gives relative humidity.
The more powerful class of air dryers for swimming pools is used to create a comfortable microclimate for bathrobes and ensuring the preservation of the building. After all, an open aqueous surface even with a relatively low temperature intensively evaporates moisture. Especially desiccitors are needed in the pool in the summer, with high humidity in the street. If the relative air humidity exceeds the optimal 50% in winter and 65% in the summer (at least 15-20%), then the conditions of stay in the pool become practically unbearable, there is a feeling of a stuff, the condensate is dripping from the ceiling, the glasses of IT. Moisture on the walls and other surfaces causes corrosion, rotting materials and education in their thickness of fungal mold, as a result of which the pool room can even be unusable for only one or two seasons.
During the repair and construction of housing, when a very intense drying of the premises is required, powerful mobile driers use, they are also called professional. These devices guarantee a significant increase in the quality of finishing work due to drying without temperature deformations of wall coating (plaster, wallpaper), floor (ties) and ceiling. They allow you to achieve low moisture content in building materials, which is especially important before laying flooring and veneer walls to prevent moisture accumulation under the decoration layer. Drying using the airstower is very economical and effective. Energy consumption is minimal compared to warming up (for example, by means of fan heaters) and subsequent removal of moisture with ventilation. Another area of application of professional devices to eliminate the effects of floods. Single of these devices quickly dry the basements and basements of flooded country houses. A common use of driers, drying garages, flooded with a spring flood.
How does the dryer work?
Cottages, in pools, as well as on the construction site, using a condensation type apparatus, which are operating on the principle of condensation of water vapor contained in the air, with a cold surface with a cold surface. Inside, such desiccants are a refrigerator with three main components: a compressor, evaporator and a condenser. The evaporator plays the role of a cold surface. When passing through it, the pre-filtered air is cooled, and the moisture in it is condensed and drained. The dried air is further fan in a condenser where it is heated. Due to the multiple passage of air through the desiccant, the humidity level in the room decreases, as a result of which the processes of evaporation of moisture from the surfaces of the walls, furniture IT.P. Things and designs dry out, the humidity of the air in the house no longer goes beyond the optimal values, and the dryer is automatically turned off. If it is impossible to remove all moisture from the room, the device will work cyclically (for example, in the pool, the air constantly absorbs evaporation and moistened).
The characteristic feature of the work of the dryer is the increase in temperature in the drying room (at the entrance to the air unit approximately 5 C is colder than at the output of it). The temperature is growing due to the released heat of evaporation and thermal energy obtained by the compressor, and this process is not always by the way. For example, hot, stuffy summer heated air may be required only in separate rooms, in that in need (let's say, in the sauna), or at a construction site. Stalls and other residential rooms in the heat for a comfortable drying of the air it is better to use a split system or window air conditioner. Cooling time (if a special air drying function is not provided) These devices are able to remove several liters of moisture outside the air conditioned space. Excessive heat is removed.
The main characteristic of the desiccant is the performance that denotes how many liters of water per unit of time it can "pull out" from the air at a certain temperature and humidity indoors. Performance is measured in liters per day and amounts to models used in cottages from 12 to 300l / day. Moreover, the values of this parameter specified in advertising and informational materials can only be achieved at air temperature + 30c and 80% humidity. Close conditions have except in the pool: +28 ... + 30c, relative humidity is 60-65%. Glit and utility rooms, with typical for middle strip +20 ... + 24c and humidity in the area of 70%, the device performance will be 6-15 liters / day. With a larger decrease in temperature, it is becoming more complicated and more difficult to achieve visible results. Operate equipment at too low temperatures is unsafe: the minimum value of operating temperatures in many models + 3c. Heat for dryers is also contraindicated - even the most endless devices are not recommended at temperatures above + 36c.
When choosing a desiccant, it is necessary to take into account the whole range of factors affecting the intensity of evaporation of moisture indoors. The number should be attributed to the temperature, humidity and consumption of supply air; the multiplicity of air exchange (natural and forced); volume of dried space; humidity of furniture, structural elements of the building; Required air parameters; Duration of the drainage process. To prevent the fateful error and not to buy a device that is not suitable for specific operating conditions, the choice of the dryer is better to entrust professionals.
Dream housewife
Portable domestic dryers have a very aesthetic appearance and resemble the ottoman or an end on wheels. For the convenience of using the device, there is usually a handle, thanks to which it can be easily transferred from the room to the room or transport from the cottage to the city apartment and back. During the day, the household desiccant is able to "pull out" from the air to 30 liters! It is enough to put the device in the desired location (10-15cm from the wall), connect to the outlet, set the level of the required humidity - and it will immediately understand the case. To achieve a positive result, it is only important for the process to be carried out in a closed room and the temperature in it corresponded to the range of operating temperatures of the dryer.
Extensive models Control only electromechanical: Start / stop buttons, humidity controller, allowing to specify its required level in the room - ranging from 30 to 80-100%. More advanced devices are equipped with a multifunctional panel with touch buttons for switching on / off and changing functioning modes. For the visual display of air temperature in the room, relative humidity, as well as the parameters of the dryer, the liquid crystal scoreboard can be mounted in the control panel. The tissue of such models provides protection against freezing and protecting the compressor. If the evaporator was covered with annea (this happens under reduced temperature and high humidity in the drying room), then the exhaustion mode automatically turns on with the controller. The protection function from frequent starts includes a compressor no earlier than through 3 minutes after shutdown.
The inconvenience during the operation of the household desiccant, which consumes no more than 300-700W electrical power from the network, as a rule, does not deliver. Is that noise level from a working device may seem unnecessary to the households (about 44-52DB), especially if it desires an overly wet room and is working without recreation throughout the night.
Inside, the driers has a retractable tank for collecting condensate by 3-12l, which as it is filling (with an increased relative humidity of air, after a few hours of operation) will have to empty (otherwise the device will automatically turn off). However, if you are not planned to move the equipment from place to place, you can organize a drainage drainage from the drainage or straight to the street through a flexible tube connected to Baku. At the same time, it will be necessary to maintain the device less frequently, once a week, for example, to check and, if necessary, washing the built-in filter, cleaning the air of the room from contamination, wipe the air intake and air duct grille with a soft cotton cloth moistened in a warm soap solution.
Speaking about specific models, we note that the choice of good dryers in the Russian market is small. Positive user feedback received MJ-E16PX from Mitsubishi Electric (Japan), CD400-16 from Dantherm (Denmark), MDB-18DEN3 Firm Ballu (China). It is worth mentioning the GENERAL CLIMATE technique (China, CF90BD model), GREE (Hong Kong, CF0.5M device), a model range of DH from Vestfrost (Denmark). Cost of dryers - from 9.2 thousand rubles. For the simplest product with manual control to 16.5-20 thousand rubles. For apparatus with electronically controlled, liquid crystal scoreboard, evaporator defrosting and compressor protection.

Desiccant and health
The household desiccant can be called a device that can benefit health. As you know, the increased humidity adversely affects the thermoregulation of the body and our state of health. At low temperature and high humidity, the heat transfer of the body is enhanced, and the person is exposed to a large cooling; And at high temperatures and high humidity, the heat transfer is sharply reduced, as a result of which extremely severe conditions are created for the body, especially when performing physical work. Domestic desiccant forces in a matter of hours to reduce the relative humidity in the room from 90- 100% to the most comfortable and favorable for a person 40-60%.
Sew - not to cut!
The desiccant in the modern pool is extremely desirable, to refuse his acquisition to anyone from developers do not advise.
Most often in private pools put compact and elegant stationary wall-mounted dryers with a capacity from 30 to 110 liters per day. Use them mainly on small and medium-sized "objects" (the area of the water mirror is up to 20-40m2). The devices are made in the form of a monoblock, which is mounted directly in the indoor pool (depending on the type - on the wall path in the wall or on the wall) and are connected to the power grid. Just like all household models, such dryers are equipped with an air filter at the air inlet. Consider the moisture condensed with them should be allocated only in the sewer, but not in the pool.
Stationary channel dryers for swimming pools with an area of water mirrors from 15-20 to 100m2 and more capable of removing moisture from the air in the amount of more than 300l / day. They can be noticeably larger than the floor and wall models, give them on design, but the functionality of the channel technology is often much wider.
Thus, the channels are sometimes equipped with a water-cooled capacitor, due to which the heat of the condensation of water vapor can be used to heal water in the pool or to prepare water used for household needs. Extractive models (CDP165 from Dantherm IDR) Set an additional single or two-piece water heater and an air damper for a substitution of fresh air (10-15% of the performance of the ventilation system). Such an "upgrade" of the desiccant makes it possible with the help of one installation to organize inlet ventilation, drainage and air heating in the pool. Recorder of technological channels (for example, Thermocond from Menerga, Germany) There are lamellar recuperators, as well as special survey valve systems, which together with modern automation allows you to maintain optimal air humidity in the pool, even with extreme climatic conditions, "fences" (tropics).
Mounted channel devices, as a rule, in a separate technical room. There are two air ducts with Sbassayin, one of which wet air is closed in the desiccant, and the second one is served dried.
Channel models with low-pressure fans are used in the case when the installation of a wall or floor apparatus in the pool is impossible (the device interferes with the passage, for example). It is possible to have such devices only be bordering the wall with a wall of the technical room (up to 350mm thick). For connection, short air ducts with ventresses offered in addition to the base bundle bundle are used.

Model CF90BD / A from General Climate Channel type with electronic control is intended for small and medium rooms
Models with high-pressure fans can be installed on the pool. The static pressure of their fans (up to 250p) allows to overcome the aerodynamic resistance of long (approximately 50 m) air ducts. The breathable air should reach all structural elements of the basin, especially panoramic windows, exterior walls and ceiling, otherwise condensate is possible on cold surfaces. If there is a glass roof, then it is obligatory and blowing it. Therefore, to deliver the dry heated air from a powerful channel device to the infused objects, a duct-collector with distribution louvre lattices are paved. They form air jets in such a way as to "press" moist air to the water surface, and the windows and elements of building structures to blow with drained air. The discharge and transportation of the moisturized air into the dryer is often carried out through the air duct-collector with air intake gratings located behind the tail ceiling. The configuration and location of the collectors are determined on the basis of the features of the enclosing design of the pool building, the shape of the bowl of IT.D.
Automatic maintenance of the required level of humidity When using wall-mounted, floor and channel models, as a rule, is provided with a built-in hygrostat (usually programmed to relative humidity 60%). However, if a frequent reinstallation of the specified parameter is assumed, it is recommended to connect to the channel remote indoor gigrostat. The dishes protect the desiccant includes a device that protects it from frost.
It should be noted that the drainage system functions not only during the use of the pool, but also during its inactivity when the supply installation does not work. Since less moisture evaporates with a fixed state of water than when operating the basin, the system performance is logically reduced. You can turn off the drying in the case of the use of a special film that covers the entire surface of the bowl when the pool is not used, and if necessary, automatically or manually winding into the roll.
Among the most popular stationary dehumidifiers for swimming pools, Kautorex (Germany), Aerial (Germany), Dantherm, General Climat should be noted. With a performance about 30l / day. The cost of the devices is about 100-185 thousand rubles, the model with a capacity of 250l / day. With the equipment for heating water in the pool and other options, there are about 390-530 thousand rubles.

We build, we dry ...
A professional desiccant can be purchased if you plan to build and finish a country house with our own forces without attracting qualified specialists.
The performance of this class devices usually lies in the range from 22 to 120 l / day. Devices are similar to lockers on large (to enhance the passability) wheels. Refrigerating machines of such dryers, as a rule, operate on Freon R407 or on another ozone-safe refrigerant. Built-in hygrometer and thawing automation successfully prevent evaporator frost. This makes it possible to use devices at low air temperatures, up to +3 S. Ana Construction. This necessity arises often. The inventory equipment includes a tracking air filter, which is mainly needed to protect the inside of the dryer from the contamination of the construction dust. Devices have a meter of hours, allowing to measure the duration of the compressor operation, can be additionally equipped with a remote hygrostat for accurate humidity control. Extract models water capacity is equipped with an integrated pump for pumping condensate to drainage.
Master (USA), Kroll, Aerial, Dantherm are presented on the Russian market of professional mobile driers. You can find models from Veab (Sweden), Remko (Germany) and some other firms. Devices with a capacity of 10-21l / day. (For example, DH25 from Master) will cost the customer in 45-53 thousand rubles.
