Working Principle

The principle of the dehumidifier is-to discharge theair vapor-cooled self-condensing liquid through daocooling,reduce the air humidity,and achieve thedehumidification effect. The working principle is topass the compressor dao,two devices (evaporator,condenser),capillary tube,and The refrigerant in thecopper pipe changes from a high-temperature andhigh-pressure gas to a low-temperature and low-pressure liquid.The air inhaled into the machine has alarge temperature difference, which quickly condenseswater droplets and slides into the drain box throughthe two fins to reduce the air humidity and achievethe effect of dehumidifcation.


The dehumidifier should be installed in a place with air circulation, and avoid placing it in dead corners, causing short circuits in the air flow and failing to achieve the required dehumidification effect. At the same time, the dehumidifier should be placed on a firm and flat floor to avoid vibration and noise. Also, avoid direct sunlight or close to heating appliances.
