    • A refrigeration system includes a compressor configured to compress a refrigerant, a condenser, and an evaporator. A heat exchanger is disposed downstream of the condenser and upstream of the evaporator, and disposed downstream of the evaporator and upstream of the compressor, the heat exchanger configured to facilitate heat exchange between the refrigerant supplied from the condenser and the refrigerant supplied from the evaporator. A first expansion device is disposed downstream of the heat exchanger and upstream of the evaporator, and a second expansion device is disposed downstream of the condenser and upstream of the heat exchanger. The second expansion device is configured to cool the refrigerant passing therethrough to cool the refrigerant in the heat exchanger supplied from the evaporator to the compressor.
    • 制冷系统包括被构造成压缩制冷剂,冷凝器和蒸发器的压缩机。 热交换器设置在冷凝器的下游和蒸发器的上游,并且设置在蒸发器的下游和压缩机的上游,热交换器构造成促进从冷凝器供应的制冷剂与从蒸发器供应的制冷剂之间的热交换。 第一膨胀装置设置在热交换器的下游和蒸发器的上游,并且第二膨胀装置设置在冷凝器的下游和热交换器的上游。 第二膨胀装置构造成冷却通过其中的制冷剂,以将从蒸发器供应的热交换器中的制冷剂冷却到压缩机。
