    • A hermetic compressor for adjusting the length and cross sectional area of a communication path as a refrigerant flow passage, so as to attenuate a discharge pulsation and consequently, a vibration and noise thereof. The hermetic compressor, which includes a cylinder head having a discharge chamber to discharge a compressed refrigerant and a discharge muffler to receive the refrigerant discharged from the discharge chamber, further includes a communication path to communicate the discharge chamber and the discharge muffler with each other, so as to allow the refrigerant to flow from the discharge chamber into the discharge muffler, and an auxiliary communication tube to increase a length of the communication path for increasing a refrigerant flow distance. The auxiliary communication path reduces the cross sectional area of a refrigerant flow passage while increasing a refrigerant flow distance, thereby attenuating a low-frequency component of the discharge pulsation.
    • 一种密封压缩机,用于调节作为制冷剂流动通道的连通路径的长度和横截面面积,以便减少排出脉动,从而减轻其振动和噪声。 封闭式压缩机包括:具有排出压缩制冷剂的排出室的气缸盖和用于接收从排出室排出的制冷剂的排气消声器,还具有将排出室与排气消音器连通的连通路径, 以使制冷剂从排出室流入排放消音器,以及辅助连通管,以增加用于增加制冷剂流动距离的连通路径的长度。 辅助连通路径减小制冷剂流路的横截面积,同时增加制冷剂流动距离,从而衰减排出脉动的低频分量。

    • An air conditioning system including a first compressor and a second compressor provided in parallel with the first compressor to vary compression capacity. The second compressor includes a housing having a compressing chamber, a vane that moves forward and backward in a radial direction of the compressing chamber, a vane guide groove formed in the housing to guide the forward and backward movements of the vane, and a vane controller that controls the operation of the vane in order to vary capacity. The vane controller includes a control valve that switches a fluid path so as to selectively apply suctioning pressure of the second compressor and discharge pressure of the first compressor to the vane guide groove and a controller that controls a fluid path switching operation of the control valve by a pulse width modulation (PWM) method in accordance with air conditioning load.
