Abstract

PURPOSE:To operate a cooler driven by a variable capacity compressor with the smallest required power loss by controlling the quantity of exhaust coolant of the compressor through a solenoid valve device using the control signal which corresponds to the deviation of room temperature. CONSTITUTION:A variable capacity compressor 1 controls the amount of exhaust by changing the eccentricity of the rotor 19 of a slide casing 13 by means of the balance between a spring 14 and the outlet pressure of the evaporator and the differnce between the outlet pressure of an evaporator 3 and the output hydraulic pressure of a solenoid valve device 4 which controls the exhaust coolant pressure in accordance with the input. A solenoid valve device 5 adjusts the pressure by alternately inversely opening and closing solenoid valves 53 and 55 using the pulse-shaped output which corresponds to the deviation of room temperature. Besides, a variable flow rate expansion device 4 receives the coolant pressure at the outlet 31 of an evaporator 3 by means of a diaphragm 43, changes the aperture area of an orifice 41 by its balance with a spring 44 and the taper-shaped tip 45 of a measuring rod 45, and thus controls the amount of the flow-in coolant.
