A vapor injection refrigerant system includes: a compressor; a condenser coupled to the compressor; an evaporator coupled to the condenser; and a cooler coupled to the condenser. The compressor includes at least a first stage and a second stage and is configured to output refrigerant in vapor form. The cooler is configured to inject refrigerant in vapor form into the second stage of the compressor. In addition, the system may include a three-way valve having a first outlet coupled to the second stage of the compressor and a second outlet coupled to the outlet of the evaporator; and a control module configured to control the three-way valve to inject refrigerant in vapor form into the second stage of the compressor at a pressure greater than that of the first stage of the compressor. Other examples of vapor injection refrigerant systems are also disclosed.
一种蒸气喷射制冷剂系统,包括:压缩机;联接到压缩机的冷凝器;联接到冷凝器的蒸发器;和联接到冷凝器的冷却器。压缩机包括至少第一级和第二级并配置成输出蒸气形式的制冷剂。冷却器配置成将蒸气形式的制冷剂喷射到压缩机的第二级中。另外,系统可包括:三通阀,具有联接到压缩机的第二级的第一出口和联接到蒸发器的出口的第二出口;以及控制模块,控制模块配置成控制三通阀以将蒸气形式的制冷剂以大于压缩机的第一级的压力的压力喷射到压缩机的第二级中。还公开其它示例蒸气喷射制冷剂系统。
