The refrigerator of the refrigeration type dehumidifier is used as a cold source, and the direct evaporative cooler is used as a cooling device to cool the air to below the zero point temperature, to precipitate water vapor that is greater than the saturated moisture content, to reduce the absolute moisture content of the air, and to reuse the wind or All condensed heat heats the cooled air, thereby reducing the relative humidity of the air and achieving the purpose of dehumidification.
Internal circulation of the dehumidifier: through the operation of the compressor → discharge of high temperature and high pressure gas from the exhaust port → into the condenser cooling → into low temperature high pressure gas → through the capillary closure → into a low temperature and low pressure liquid → evaporation through the evaporator → heat absorption → Back to the compressor into a low temperature and low pressure gas, so reciprocating.
External circulation of the dehumidifier: in the case of a normal start-up → through the operation of the fan → inhalation of moist air from the air inlet → through the evaporator → evaporator The moisture in the air is adsorbed on the aluminum sheet → becomes dry air → passes through Condenser heat dissipation → blow out from the air outlet.
Grain warehouse dehumidifier works
The working principle of food warehouse dehumidifiers The storage of grain needs a relatively dry and airtight environment. Otherwise, the excessive moisture content in the air will cause mildew in the stored grain, which will affect the quality of the food. Food warehouse dehumidifier - The dehumidifier uses the principle of compressor refrigeration to dehumidify and is used for dehumidification in grain warehouses.
