Claims

[Scope of utility model registration request]

A refrigerant compressor that compresses refrigerant gas, a condenser that liquefies the refrigerant gas discharged from this refrigerant compressor, a high-pressure float that detects the liquid level in this condenser, and an output signal from this high-pressure float. A refrigeration system with a refrigerant circuit consisting of a pilot pipe that leads to the main valve for liquid level control via a solenoid valve, and a flooded evaporator that evaporates the refrigerant sent from the condenser to the main valve for liquid level control. In the apparatus, a detector capable of detecting a temperature difference between the liquid part and the gas part of the flooded evaporator is provided at a predetermined position in the refrigerant circuit, and the detector is installed in the gas part of the flooded evaporator. A gas part sensor is disposed in the liquid part, and a liquid part sensor is disposed in the liquid part, and when the gas part sensor does not secure a predetermined value, the detector sends a close signal to the solenoid valve, and the liquid part sensor sends a closing signal to the solenoid valve. A refrigeration system characterized by controlling a main valve for liquid level control.
