Abstract

PURPOSE:To prevent a rapid change of consumption power and evaporator temperature, in an air conditioning device with a variable displacement compressor for changing a delivery quantity of heat absorption medium, by constituting the device in such a manner that primary and secondary air temperatures of the evaporator are compared with a reference value to control the coupling and delivery quantity of the compressor. CONSTITUTION:A primary air temperature thermistor 13 and secondary air temperature thermistor 14 in an evaporator 10 and a potentiometer 5 are connected in series to the input side of an electric circuit 6, and a variable resistor 15 is connected in series to this circuit, then a cooling capability decision reference value is changed by the variable resistor 15. In this constitution, the control circuit 6 detects a real cooling degree of the evaporator 10 from the secondary air temperature 14 to drive a servo motor 3 by a deviation value signal V1 with the reference value 15. Further a clutch 2 is operated to couple a compressor 1 only when the primary air temperature 13 is higher than the reference value 15. In this way, when the cooling degree of the evaporator 10 is obtained by the primary air, refrigerating operation is not performed, and a rapid change of consumption power and evaporator temperature can be prevented.
