Abstract

PURPOSE:To obtain proper operation of a car air-conditioner and economize the engine power for car running by controlling the amount of blast of an electric fan in proportion to the number of unemployed cylinders in a multi-cylinder compressor. CONSTITUTION:By-pass routes 49-54 are provided to cylinders 43-48 in a multicylinder compressor 1, and electromagnetic valves 22-27 are arranged thereon, while an electronic arithmetic unit 33 is provided to control the electromagnetic valves 22-27, a condenser-cooling electric fan, 3 and a fan motor 7 for an evaporator. In this construction, when the electromagnetic valves 22-27 are electrified and opened, the by-pass route 49 is opened to make the compressing works of refrigentrant in the cylinders 43-48 unemployed. Meanwhile, as the cooling capaity is lowered in proportion to the increase of the number of unemployed cylinders, the number of revolutions for the condenser-cooling electric fan 3 is reduced. Consequently, the compressor can be controlled proportionally to control the car-room temperature smoothly and properly, and the condensing pressure for refrigerant can be kept at a constant level for promoting the efficiency.
