一、Internal circulation of dehumidifier：
                

                  Through the operation of the compressor→the vent discharges
high-temperature and high-pressure gases→enter the condenser
for cooling→become low-temperature and high-pressure gases→
closure by capillary→become low-temperature and low-pressure
gases→evaporation related heat absorption through the
evaporator →return to the compressor, and become low-temperature
and low-pressure gases

                 二、External circulation of dehumidifier：

                 Under the circumstance of normal startup→through the operation
of fan→damp air is inhaled through the air intake→pass the
evaporator→the evaporator absorbs the water in air to aluminum
sheet→become dry air→heat dissipation through the condenser→
blow out from air outlet
