Abstract

PURPOSE:To improve the feeling of cooling at the acceleration of an automobile, by providing a variable-capacity compressor in a refrigeration cycle and detecting the acceleration to reduce the capacity of the compressor to prevent the temperature just downstream to an evaporator from rising due to the stoppage of the compressor at the acceleration. CONSTITUTION:When an accelerator pedal is pressed down beyond a set level, a switch 25a is turned on and an acceleration detector circuit 25 keeps a high output level for a prescribed time and transistors 164a, 165 are forcedly turned on. As a result, a transistor 164b is turned off, transistors 166, 167, 171 are turned on and transistors 168, 169, 170 are turned off so that an electrical current flows to a servomotor 17 through the emitter and collector of the transistor 171 and the collector and emitter of the transistor 167. For that reason, the servomotor 17 rotates backward to decrease the rotation angle of the variable ring of a variable-capacity compressor to reduce its capacity. Since the capacity becomes the minimum (one third of the maximum), the load upon the engine is diminished and the acceleration performance is improved.
