A subcooler is mainly composed of a compressor, condenser, expansion valve, and evaporator, and can be automatically controlled by a control system.

[0003] During use, the traditional subcooling water unit liquid level detection and control device uses a compressor to generate high-pressure and high-temperature refrigerant gas, and through the heat dissipation of the condenser, the temperature of the refrigerant is reduced and converted into liquid.
