Abstract
PURPOSE: To prevent the overloading and the returning of liquid in a compressor by providing an evaporating pressure adjuster, an overheating computing adjuster, and a cooled side thermal adjuster as well as an evaporating pressure transmitter and a thermal transmitter in a pipe connecting between an evaporator and the compressor.
CONSTITUTION: A refrigerating cycle is composed of evaporators 1a and 1n, a compressor 2 with a capacity adjusting mechanism 2a, a condenser 3, and an expansion valve 4a. An evaporating pressure transmitter 5 and a thermal transmitter 6 are provided to a pipe 10 connecting between evaporators 1a and 1n and the compressor 2. An overheating computing adjuster 7 is connected with the evaporating pressure transmitter 5, the thermal transmitter 6, and the contact "a" of a changeover switch 11a, while an evaporating pressure adjuster 8 with the evaporating pressure transmitter 5 and the contact "c" of changeover switches 11a and 11b and the cooled side thermal adjuster 9 with changeover switches 11a and 11b, are respectively connected. In this construction, the compressor is prevented from overloading and returning of the liquid.
