Working principle of air dryers

Air dryer is a device designed to reduce the level of humidity in the room. Why do I need to reduce the amount of moisture in the air space? To answer this question, here is the main negative impacts of high levels of humidity in the premises:

• corrosion (rusting) steel structures and other subsidiary of metal elements in the room;
• violation of the integrity of (cracking) of concrete, brickwork, decorative materials;
• deterioration of the electrical properties of structural wiring: oxidation of contacts plug sockets and switches, reduction of insulation resistance of wires and cables;
• the appearance of mold, “flowering walls, odors and bacteria;
• reduced storage life of products: food, medicines, cleaning products, building materials, etc.

Dehumidification can be accomplished in several ways, below we present them briefly.

The principle of dehumidification in the room through assimilation is based, which removes moisture from the air and pumping facilities outside the room.

The way to reduce the level of humidity in the premises not suitable for places that are humid climates near bodies of water, for example, or when the humidity is high, irrespective of the climatic characteristics of the area, for example, in winter or in rainy weather. Additionally, driers of this type have a very low efficiency, so preference is given to more efficient devices-condensation type.

The device, which is achieved by dehumidification assimilation, have fairly low efficiency, so preference is given to more efficient devices condensation type.

Principle of operation the dehumidifier type is based on the phenomenon of condensation of water vapor to heated air to the cold evaporator. Moisture-condensing on the surface of the evaporator is removed in a specific container. The amount of moisture that the air is removed from the dryer at a time, what is the main setting of the device.

The only disadvantage of condensing dehumidifiers is the ambient air temperature by several degrees. This dehumidifier is taken into account only if the room where the dehumidifier is installed, a small square.

Another type of dehumidifier is a device whose principle is based on the adsorption of moisture contained in the air with the help of so-called adsorbents.

One of the most common adsorbents-silica gel. The substance is used to remove the moisture in the Thermosiphon dehydrators filters, power transformer oil type, as well as air dehydrators adsorption type.

Significant lack of adsorption dehumidifiers that silica gel or other adsorbent can absorb only a certain amount of moisture, then it has to be replaced or regenerated.
