制冷单元控制器的准备

The materials in the drying room vaporize the moisture in the materials in the form of hot air, and the evaporated steam is discharged by the moisture drainage system to dry the materials. The refrigerant after condensation and heat release changes into low temperature and low pressure liquid through the throttle valve. As the pressure drops suddenly, the liquid refrigerant enters the evaporator and will continuously absorb the low-level heat energy of the surrounding air and quickly evaporate into a gas state. The refrigerant that has absorbed a certain amount of energy returns to the compressor and enters the next cycle. In this way, the continuous circulation of refrigerant can transfer the heat in the air to the air temperature in the heating room in the drying room.
