Description

Solenoid valve for Cold storage unit

Prevent the high-pressure refrigerant liquid from entering the evaporator when the compressor is shut down, prevent the low pressure from being too high when the compressor is started next time, and prevent the liquid hammer of the compressor.
When the temperature of the cold storage reaches the set value, the temperature controller acts, the solenoid valve loses power, and the compressor stops when the low-pressure pressure reaches the shutdown set value. When the temperature in the cold storage rises to the set value, the temperature controller acts, the solenoid valve is powered on, and the compressor starts when the low-pressure pressure rises to the compressor startup set value.
