The working principle of dehumidifier

What is the working principle of dehumidifier?What is the Internal circulation and Outer circulation of dehumidifier?


1. Internal circulation of dehumidifier:

Through the operation of the compressor → discharge high-temperature and high-pressure gas through the exhaust port → enter the condenser for cooling → become a low-temperature and high-pressure gas → pass through the capillary tube → become a low-temperature and low-pressure liquid → evaporate and absorb heat through the evaporator → return to the compressor to become Low temperature and low pressure gas. So it goes back and forth.


2. Outer circulation of dehumidifier:

In the case of normal start up → through the operation of the fan → the moist air is sucked in from the air inlet → through the evaporator → the evaporator absorbs the moisture in the air on the aluminum sheet → becomes dry air → passes through the condenser to dissipate heat → blow out from the outlet.
