    • During a heating mode, higher-pressure refrigerant having passed through a condenser within an air-conditioning duct is divided into two portions. One portion is depressurized by a first depressurizing device to an intermediate pressure. Heat exchange is performed in a refrigerant-refrigerant heat exchanger between the other portion of the higher-pressure refrigerant having just passed through the condenser and the intermediate-pressure refrigerant having just passed through the first depressurizing device. During the heating mode, the higher-pressure refrigerant cooled in refrigerant-refrigerant heat exchanger 23 is supercooled by a supercooling device within the air-conditioning duct. Then, the supercooled higher-pressure refrigerant is depressurized by a second depressurizing device to a lower pressure, thereby vaporized in an outdoor heat-exchanger.
    • 在加热模式期间,通过空调管道内的冷凝器的高压制冷剂被分成两部分。 一部分由第一减压装置减压至中间压力。 在刚刚通过冷凝器的高压制冷剂的另一部分和刚刚通过第一减压装置的中压制冷剂之间的制冷剂 - 制冷剂热交换器中进行热交换。 在加热模式中,在制冷剂 - 制冷剂热交换器23中冷却的高压制冷剂由空调管道内的过冷却装置过冷却。 然后,将过冷却的高压制冷剂由第二减压装置减压至低压,在室外热交换器中蒸发。

    • A refrigerant cycle system includes a gas-liquid separator for separating gas-liquid refrigerant into gas refrigerant and liquid refrigerant. The gas-liquid separator has a liquid-suction pipe for introducing liquid refrigerant from the gas-liquid separator to a decompressing unit, and a gas-suction pipe for introducing gas refrigerant from the gas-liquid separator to a compressor. The gas-suction pipe has a suction hole for sucking liquid refrigerant therein, and the suction hole is provided at a position lower than an open end of the liquid-suction pipe. Because a height of a surface of liquid refrigerant in the gas-liquid separator is constantly equal to or higher than the open end of the liquid-suction pipe regardless of change in a heating load of the refrigerant cycle, liquid refrigerant is constantly sucked into the gas-suction pipe from the suction hole. Thus, liquid refrigerant in which lubricating oil is dissolved can be constantly introduced into the compressor, thereby preventing shortage of lubricating oil in the compressor. On the other hand, in the refrigerant cycle, an oil-discharging mode is selectively set at a starting time of a heating mode so that lubricating oil staying in an evaporator is discharged. Therefore, lubricating oil is sufficiently returned to the compressor even when the heating mode is switched from a cooling mode.
    • 制冷剂循环系统包括用于将气液制冷剂分离成气体制冷剂和液体制冷剂的气液分离器。 气液分离器具有用于将液体制冷剂从气 - 液分离器引入减压单元的吸液管,以及用于将气液制冷剂从气 - 液分离器引入压缩机的吸气管。 吸气管具有用于吸入液体制冷剂的吸入孔,吸入孔设置在比吸液管的开口端低的位置。 由于气液分离器中的液体制冷剂的表面的高度恒定地等于或高于吸液管的开口端,而与制冷剂循环的加热负荷的变化无关,液态制冷剂被不断地吸入 吸气管从吸气孔。 因此,可以将压缩机内的润滑油溶解的液体制冷剂恒定地引入压缩机中,防止压缩机中的润滑油不足。 另一方面,在制冷剂循环中,在加热模式的开始时刻选择性地设定排油模式,从而排出滞留在蒸发器中的润滑油。 因此,即使在从制冷模式切换加热模式的情况下,也能够将润滑油充分返回压缩机。

    • In a refrigerant cycle system, a gas-liquid separator has a gas-suction pipe for introducing gas refrigerant from the gas-liquid separator to a compressor. The gas-suction pipe has an open end opened in a gas-refrigerant area in the gas-liquid separator, a first suction hole, provided in a liquid-refrigerant area of the gas-liquid separator, for sucking liquid refrigerant containing lubricating oil, and a second suction hole provided in the gas-refrigerant area of the gas-liquid separator. The second suction hole for sucking gas refrigerant is formed in the gas-suction pipe at a downstream refrigerant side of the first suction hole. Therefore, a flow rate of gas refrigerant passing through around the first suction hole in the gas-suction pipe is decreased due to introduction of gas refrigerant by the second suction hole, thereby decreasing quantity of liquid refrigerant sucked from the first suction hole. Thus, liquid refrigerant is prevented from excessively returning to the compressor, even if the first suction hole is enlarged.
    • 在制冷剂循环系统中,气液分离器具有用于将气体制冷剂从气 - 液分离器引入压缩机的吸气管。 吸气管具有在气液分离器的气体制冷剂区域中敞开的开口端,设置在气液分离器的液体制冷剂区域中的用于吸入含有润滑油的液体制冷剂的第一吸入孔, 以及设置在气液分离器的气体制冷剂区域中的第二吸入孔。 用于吸入气体制冷剂的第二吸入孔形成在第一吸入孔的下游制冷剂侧的吸气管中。 因此,由于吸入管中的第一吸入孔周围的气体制冷剂的流量由于第二吸入孔引入气体制冷剂而降低,从而减少从第一吸入孔吸入的液体制冷剂的量。 因此,即使第一吸入孔扩大,也能够防止液体制冷剂过度地返回压缩机。
