How Does a Whole House Dehumidifier Work?

Dehumidification refers to the removal of excess moisture from the air. Keep the air humidity within a comfortable level range. Dehumidifiers can achieve this through simple physical principles, where water vapor condenses into liquid form.

The central home dehumidifier provided by Preair works efficiently and intelligently. The fan of the dehumidifier absorbs moist air into the machine. When the air flows through the evaporator, the moisture in the air is condensed into liquid water and then falls into the water tank or flows into the drainage pipe. The home dehumidifier system equipped with drainage hoses, which is much more convenient. The drainage pipe can drain the collected water conveniently and the dehumidifier can continuous work without emptying the water tank. For other types of dehumidifiers, condensate is stored in a water tank and must be regularly emptied. Generally, the dehumidifier’s fan will blow dry air into the room, achieving the exchange of wet and dry air, thereby reducing indoor humidity.

The working mode of the whole house dehumidifier is roughly the same as that of portable devices, but it requires less maintenance. This type of dehumidifier is an additional option for home heating and cooling (HVAC) systems, which rely on a piping system to provide heating or cooling air. The household dehumidifier works together with the air conditioner to make the cooling process more efficient, or on cool days, it can automatically start when the indoor humidity level exceeds the required level. The whole house dehumidifier can remove excess moisture from the air, which is sucked in through the home's return air duct system. When the cooling coil of the dehumidifier cools the humid air, the generated condensate is collected and directly discharged into the drainage pipe, assisted by a pump.
