Abstract

PURPOSE:To perform displacement control so properly by altering a displacement control constant according to a difference of refrigerant gas temperature in both inlet and outlet pipelines of an evaporator. CONSTITUTION:Refrigerant gas temperature in both inlet and outlet pipelines of an evaporator 8 is detected by temperature sensors 24, 22, and a temperature difference is operated at an arithmetic and control unit 23. This output is inputted into a superheat comparator 25, whereby a displacement control constant is altered by a circuit 26 with blowoff air temperature in the evaporator 8 added. Consequently, the displacement control constant of the compressor is alterable in relation to control over an expansion valve by a temperature sensing cylinder, and a variation range of the displacement control is controlled, thus the compressor displacement control is rationalized.
