Compressor cooling system is the most important part of condensing dehumidifier. It can condense steam and reduce the moisture content in the air. The core of the cooling system is a compressor that compresses and pumps refrigerant, forcing it to circulate throughout the entire system. The higher the pressure, the higher the temperature. The compressed refrigerant (gaseous) is transported through a pipeline to the condenser, where it is cooled
The heat of the refrigerant is received by the air around the exchanger (condenser). Due to a decrease in pressure and temperature, the refrigerant changes from a gaseous state to a liquid state. The condensed refrigerant absorbs steam through a dehydration filter and can enter the dryer during its manufacturing or maintenance. After passing through the filter, the liquid flows through a throttle valve (capillary or expansion valve), and its flow resistance creates a pressure difference, causing the refrigerant to expand and evaporate. The evaporation process occurs during evaporation?? In the hair
Unlike condensation, evaporation can cause a decrease in pressure and temperature. Due to this phenomenon, air releases heat into the refrigerant (and causes it to evaporate). The air temperature is lower than the dew point, which will cause excessive moisture to condense on the walls of the condenser. The expanded refrigerant is sucked in again by the compressor, and the entire cycle restarts
If operating at lower ambient temperatures, the condensed water in the evaporator may freeze, which increases the resistance of the airflow in the exchanger. To avoid this situation, the electronic control system periodically opens the solenoid valve. This redirects the hot refrigerant (gaseous) back to the evaporator. This causes the ice to melt and flow towards the condensate tank
