Air dryer for the pool: types, parameters, principle of operation, popular models

High humidity is a “painful” problem in rooms with pools, the reason for which is intensive evaporation. To solve it, there is an air dehumidifier - a complex of freon units assembled in one housing, the purpose of which is to extract moisture from the air masses and maintain its optimal level.

Device purpose

An excess of moisture results in the accumulation of condensation on the walls, ceiling, windows, and also contributes to the development of microbes, the appearance of mold and corrosion in enclosed spaces with an artificial reservoir. This phenomenon threatens an uncomfortable environment for visitors, because the preservation of a waterlogged microclimate may cause people who are prone to cardiovascular disease to have asthma attacks or shortness of breath. In addition, there is a high probability of contracting various diseases, due to the multiplication of harmful microorganisms in these places.

Excessive humidity leads to deterioration of equipment and the destruction of the decoration of the rooms, which ultimately will require repair work in the building.

For these reasons, it is advisable to install dehumidifiers in rooms with a pool. They provide control and maintenance of an optimum level of humidity, absorb condensation and give out dry and warm air.

Principle of Operation and Specifications

Most often, in buildings with a pool, a freon type dehumidifier is used, which is based on two heat exchangers: a cold one (evaporator) and a hot one (condenser) arranged in series. When moisture saturated air enters the equipment, the fan redirects it to the evaporator, in which condensate is removed and flows into a specially allocated container, and then it is discharged into sewer. The drained cold atmosphere, passing through the condenser, is heated to the set temperature and discharged back into the room.

In time to turn on the device helps the built-in hygrostat. It controls the maintenance of the humidity level in the room in accordance with the set indicator on the equipment and activates when it increases, and when the microclimate reaches the norm, it turns off.

How the dehumidifier works, you can see in this diagram:

When choosing a dehumidifier for a pool, you should pay attention to its specifications:

• Range of humidity and air temperature.
• Drainage capacity (l / day).
• Type and amount of refrigerant use (kg).
• Air consumption (loss) (cubic m / h).
• Power supply: current consumption (A) and power (kW).
• Noise Level (dB).
• The cycle of continuous operation.
• Degree of protection.

The main characteristic of the device is its performance - the amount of moisture that it can absorb per day. This indicator is designed for a specific area of ​​the water mirror and varies from 100 to 300 liters.

Types of devices: advantages and disadvantages

Dehumidifiers are divided into two types: stationary (have high power and are suitable for rooms with artificial ponds) and portable (devices on wheels that allow you to move them throughout the building, but are more used to eliminate leaks or during finishing work).

Air dehumidifiers for pools, depending on the principle of their operation, are divided into:

1. Assimilation - based on the removal of moist air from the room, replacing it with dry, extracted from the outside of the building. They are rarely used, since the performance of such equipment is much less than its energy consumption, which makes the use of such dehumidifiers not rational.

1. Adsorption - the removal of moisture from the air masses is made through the use of an adsorbent - a substance, having a high ability to absorb various liquids on its surface, which is located in the rotor devices.

This process is ensured by the operation of two or three fans: the first absorbs air from the hall and moves it to the rotor, where the adsorbent, entering into a chemical reaction with it, removes moisture. Then the dry atmosphere enters the distribution chamber, where it is divided into regeneration and exit back.

The regeneration air mass is heated in a separate chamber and redirected by a second fan. back to the rotor, where condensate is blown out of it, which is either discharged into the street or collected in tank. The third fan works by removing dry air back into the room.

The main advantages of this type of dehumidifier are:

• power;
• high performance;
• can work at a temperature of -20 C (but no more);
• air temperature remains unchanged;
• can reduce humidity by up to 30%.

The disadvantages of adsorption dryers are as follows:

• high price for equipment;
• some models (household) can give out air 5-7 degrees higher in comparison with the initial temperature;
• There is a need to bring a hose to accumulate fluid and bring it outside.

1. Condensation - with the help of a fan, moist air enters the device and moves to a refrigeration circuit containing a heat exchanger, which, when interacting with the heat of the air masses, is heated. The refrigerant passes through the pipes to it, passing from a liquid to a gaseous state, and cools it. As a result of the temperature difference, condensate occurs on the heat exchanger, and the refrigerant moves to the compressor, where it returns to the liquid state during compression. The heat released in this case heats the drained atmosphere, after which it enters the room. Continuous operation of the equipment will be able to drain all the air in the room without major changes in the microclimate.

Advantages of condensing dehumidifiers:

• acceptable price;
• equipment power;
• low power consumption;
• functionality.

The main disadvantages of this type are:

• temperature limits (from +15 to +30 degrees);
• cannot reduce humidity by more than 40%.

When selecting and buying a dehumidifier for the pool you need to choose way to place it:

1. Wall used in cases where you need to save floor space. Among the advantages - low cost, optimization of hidden condensate drain, the ability to paint the device for the interior. The disadvantages are the lack of fresh air. One device will not be able to maintain the necessary humidity, therefore it is recommended to place several devices at once.
2. Floor attractive in that you can allocate a place near the pool and, if necessary, move the device to another.
3. Channel suitable for rooms with a large area, it is often installed in the next room, and air is drawn in and out through the channels located around the room. Among the advantages of such equipment are high performance, the absence of noise during operation due to the need placement in a separate technical room, as well as the existence of the ability to add a fresh air. Among the disadvantages are the high price of the device, the complicated installation process and the need for regular maintenance.

The use of air dehumidifiers for pools, whether it is ducted, refrigerated or with absorption, has several advantages: they are easy to operate and will please you for a long time over the years, they are considered environmentally friendly devices and are able not only to control the level of moisture, but also to clean the air of dust, germs, dilute with a fresh atmosphere from the outside. However, it is not worth getting carried away with draining, because this can cause various colds for visitors.
