Abstract
A refrigerating apparatus includes a compressor, a condenser, an expansion valve and an evaporator interconnected in that order. A hot gas bypass pipeline with a solenoid valve is connected at one end between the compressor and the condenser and at the other end between the expansion valve and the compressor. A temperature detecting switch detects a temperature of the piping between the discharge side of the evaporator and the intake side of the compressor. The temperature at which the detection switch can respond is set at a predetermined value at which no influence is exerted on components of the apparatus formed of thermoplastic resin. When the temperature at the intake side of the compressor rises to the predetermined value, the detecting switch detects this predetermined value to cause the compressor to stop operating.
