摘要：PURPOSE:To operate accurate over-heating control by providing a coolant container between the exit of an evaporator and the inlet of a compressor and by controlling the degree of opening of an expansion valve provided on the inlet side of the evaporator corresponding to the height of the liquid surface of the coolant in the container. CONSTITUTION:When the load of evaporator 5, which is provided with heat exchange tube 51, becomes large, the enthalpy of the coolant of the output of evaporator 5 increases, over-heating becomes large, and over-heated gas flows into coolant container 6. Over-heated gas comes into contact with coolant in container 6 and exchanges heat with it; and a part of coolant evaporators and the enthalpy decreases. The coolant becomes nearly dry saturated gas and flows out form the exit. The height of the liquid surface of the coolant is lowered by the evaporation of the coolant. By the operation of controller 8, the degree of opening of expansion valve 4 becomes large. A large quantity of coolant which has passed compressor 1, condenser 2 and the liquid receptacle enters evaporators 5; and the coolant flowing from its exit is adjusted into dry saturated gas.
