Air dryer for the apartment: the principle of work, how to choose, rating the best

High humidity in the apartment worsens the living conditions, causes the development of fungus, mold, the appearance of a musty smell. All this often leads to health problems. A device for drying indoor air is capable of preventing this. It will allow you to create the optimal microclimate for health and comfortable living.

Purpose of the air dryer

The cause of increased humidity in the room can be various factors: the installation of window openings with non-compliance with standards, poor hydro- or thermal insulation, and ventilation problems. To stabilize the moisture level in this case, an air dryer is used. This is a unique device that can lower and maintain a given level of humidity in a living room.

Depending on the purpose, household and industrial dehumidifiers are distinguished. The main difference between them is productivity (the amount of processed air over a certain period of time). The apartments use appliances for domestic use, which can absorb moisture up to 50 liters per day, while cleaning the air from harmful microparticles.

Types of dehumidifiers and the principle of their work

Dehumidifiers are classified according to two criteria: type of device and principle of operation.

In the first case, we are talking about various ways of installing and placing the device in a residential building. Dehumidifiers are floor, wall, universal and hidden.

Depending on the principle of operation, the adsorption and condensation types of devices are distinguished, as well as a dehumidifier with the assimilation property.

Adsorption

The functioning of this dehumidifier is based on the adsorption properties of its substances and materials. In the internal part of the device there is a sorbent that absorbs excess moisture, draining the indoor air. The main disadvantage of these devices is the frequency of change of the adsorbent.

Condensation

Condensation dehumidifiers are in the greatest demand. Such a device is the best suited for a house or apartment.

The principle of operation of devices is based on the condensation of water vapor. Most dehumidifiers for the home work on the principle of air conditioning. The device has built-in “warm” and “cold” radiators (evaporator and condenser).

Ventilated air, getting into the evaporator, is cooled. Due to this, it condenses, and then accumulates in a special vessel (pan), from which it is regularly necessary to drain the liquid. If this is not done, the device will automatically turn off.

Some models of dehumidifiers of this type have an outlet to which a pipe is connected to drain water to the street, into the sewer system.

With assimilation method

The principle of operation of this type of dehumidifier is the exchange of air masses between the room and the street. Humid air is thrown out of the room, and fresh air is drawn in from the street. In the process of circulation, the humidity in the room decreases.

The disadvantages of the device must include significant heat loss, which goes along with the moist air to the outside, as well as energy costs for heating the retracting air. Among the disadvantages of assimilation-type dehumidifiers are the inability of the device to drain air in humid weather and the inability to use it in regions with a humid climate.

Key selection criteria

When choosing a device for dehumidifying air in an apartment, you should first decide on your preferred view.

Other selection criteria include the following:

Performance

Each device has a specific performance, which indicates the amount of moisture removed per hour or day. This indicator in the characteristics of the model is indicated in the form of abbreviations "l / h" or "l / s".

If you purchase a device of too low power, the desired effect will not be achieved and such a dehumidifier will work continuously, at the limit of its capabilities. Such a load will significantly reduce its service life. Purchasing a device with performance exceeding needs will lead to a rapid decline in performance. moisture in the room, so in the future the dehumidifier will only work at a loss due to overruns electricity.

In order to choose a device with the necessary performance, you should know the moisture indicator in the room. It can be calculated as follows: the area (quadrature) of the room where the air will be dried must be multiplied by a factor of 0.7. This will give an approximate indicator, which should be guided when choosing.

Noise level

If the air in the apartment is drained, a too noisy device can cause discomfort, especially when used at night. It is recommended to pay attention to models whose noise level does not exceed 45 dB.

Manufacturer

Before buying, it is recommended to consult with a specialist in advance which device is suitable for a specific case, based on the ratio of "price-quality", as well as popularity, reliability and performance models.

Catchment volume

The larger the volume of the condensate collection tank, the less often it will have to be drained from there.

Power consumption

The energy consumption of a dehumidifier is primarily dependent on performance. There are high-efficiency models on the home appliance market that at the same time consume little electricity.

Additional features

These include the presence of a hygrometer (it displays a moisture indicator on the display or screen), sound alerts in case of overflow containers for collecting water, a timer, the function of ionization of the air, the function of automatic shutdown of the device during incorrect operation or when filled reservoir.

Also, in addition, some models of air dryers can perform the functions of a hydrostat, an air purifier.
