1 热气旁通阀控制式独立空调制冷系统在热气旁通阀控制式独立空调制冷系统中,制冷剂的循环和在一般空调中制冷剂的循环基本相同,即制冷剂的循环为:压缩机→冷凝器→储液器→过冷器→干燥器→膨胀阀→蒸发器→压缩机(图1)。压缩机曲轴通过联轴器与副发动机(辅助发动机)的飞轮直接 1 hot gas bypass valve control independent air conditioning and refrigeration system In the hot gas bypass valve control independent air conditioning and refrigeration system, the refrigerant cycle and in the general air conditioning refrigerant cycle is basically the same, that is, the refrigerant cycle: compressor → Condenser → reservoir → subcooler → dryer → expansion valve → evaporator → compressor (Figure 1). The compressor crankshaft passes through the coupling directly to the flywheel of the secondary engine (auxiliary engine)
