    • A refrigerating system for air-conditioning an air-conditioned area, and incorporating therein a variable capacity refrigerant compressor in which the delivery amount of the compressed refrigerant is varied by changing the stroke of the reciprocating pistons which are operatively connected to a swash plate mechanism by changing its angle of inclination in response to a change in the pressure in a crank chamber, a condenser for condensing the compressed gas-phase refrigerant from the compressor, a pressure reducing unit for reducing the pressure of the liquid-phase refrigerant, an evaporator for vaporizing the liquid-phase refrigerant by removing heat from the air, around the evaporator, which cools the air-conditioned area, and a refrigerant supply conduit supplying the crank chamber of the compressor with a part of the liquid-phase refrigerant flowing in a portion of the refrigerant conduit extending from the condenser to the evaporator so that during the minimum capacity operation of the compressor, the compressor is cooled and lubricated by the supplied refrigerant. A flow regulating unit for adjustably regulating the flow of the liquid-phase refrigerant flowing through the refrigerant supply conduit is also arranged.
    • 一种用于对空调区域进行空调的制冷系统,并且在其中并入可变容量的制冷剂压缩机,其中通过改变可操作地连接到斜盘机构的往复活塞的行程来改变压缩制冷剂的输送量, 响应于曲柄室中的压力变化而改变其倾斜角,用于冷凝来自压缩机的压缩气相制冷剂的冷凝器,用于降低液相制冷剂的压力的减压单元,用于 通过从空气中除去冷却空调区域的蒸发器周围的热量来蒸发液相制冷剂,以及向压缩机的曲轴室供应一部分液态制冷剂的制冷剂供应管道, 的制冷剂导管从冷凝器延伸到蒸发器,使得在最小容量操作期间 压缩机,压缩机被供应的制冷剂冷却和润滑。 还布置有用于可调节地调节流过制冷剂供应管道的液相制冷剂的流动的流量调节单元。
