摘要： A refrigerating cycle has a condenser, an evaporator, a variable displacement compressor, and an expansion valve. The variable displacement compressor is connected between the condenser and the evaporator to form the refrigerating cycle, and includes a control valve designed to provide a control valve characteristic sloping downward with increase in a discharge pressure. The expansion valve is connected between the condenser and the evaporator, to return a refrigerant from the condenser through the evaporator to the variable displacement compressor, and designed to provide an open valve characteristic whose slope is approximately equal to the downward slope of the control valve characteristic.
