空调机
摘要：
空调机(100)在制冷循环回路中封入有非共沸混合制冷剂以及冷冻机油。并且，将压缩机(1)的吸入口和储液器(2)连接的制冷剂配管即吸入配管(21)的、与储液器(2)连接的一侧的端部向该储液器(2)的内部突出。此外，在空调机(100)的吸入配管(21)中，在配置于储液器(2)的内部的范围中的比储液器的中央部高的位置形成有回油孔(19)。空调机(100)的控制装置(16)控制减压装置(4)的开度，以便使流入储液器(2)的制冷剂的干度小于1。
摘要（英）：

An air conditioner (100) that has enclosed in a refrigeration cycle circuit a non-azeotropic refrigerant mixture and a refrigerating machine oil. Intake piping (21) that is coolant piping that connects an intake opening and accumulator (2) of a compressor (1) protrudes into the accumulator (2) at an end part that is on the side connected to the accumulator (2). An oil return hole (19) is formed in the intake piping (21) of the air conditioner (100) at a position that is higher than an accumulator center part and that is in a range that is inside the accumulator (2). A control device (16) of the air conditioner (100) controls the opening degree of a decompression device (4) such that the dryness of coolant that flows into the accumulator (2) is less than 1.
