Working principle of mine cooling equipment
According to the principle of refrigeration system, low-temperature and low-pressure liquid refrigerant exchanges heat with the air flowing into the evaporator in the evaporator. The evaporator absorbs heat from the air, and the temperature of the refrigerant remains unchanged during the evaporation process. The liquid refrigerant evaporates into low-temperature and low-pressure gaseous refrigerant, which enters the compressor and is compressed by the compressor into high-temperature and high-pressure gaseous refrigerant. Then it enters the condenser and exchanges heat with the natural air extracted by the cooling fan in the condenser. The heat of the high-temperature and high-pressure cold coal is discharged outside the machine. The cold coal flows out of the condenser through a drying filter, filters out the moisture or other impurities contained in the cold coal during the evaporation process, and then enters the expansion valve for expansion throttling. Expansion throttling throttling is a rapid cooling process, and the refrigerant becomes a low-temperature and low-pressure liquid. After this process, The refrigerant then enters the evaporator for heat exchange and evaporation, Thus achieving the entire process of the refrigeration system, this cycle is continuous, allowing water to be continuously cooled, and then the cold air is sent from the air outlet to the desired destination through the fan.
