The present disclosure relates to a vapour compression circuit 400, 400 'for circulating a working fluid. The vapor compression circuit 400, 400 'includes a compressor 402, a first heat exchanger 404, an expansion device 406, 406', a second heat exchanger 408, a discharge line 412, a bypass line 419, 419 ', and a controller 490. A discharge line 412 extends from an outlet of the compressor 402 to an inlet of the first heat exchanger 404. The vapor compression circuit 400, 400 'is configured to operate in a heating mode 620 in which the first heat exchanger 404 operates as a condenser and the second heat exchanger 408 operates as an evaporator. The vapor compression circuit 400, 400 'is further configured to operate in a thawing mode 610 in which working fluid is directed 612 from the compressor 402 to the second heat exchanger 408 via a bypass line 419, 419' and an expansion device 406, 406 ', the bypass line 419, 419' extending from the discharge line 412 to bypass the first heat exchanger 404.
本公开涉及用于循环工作流体的蒸汽压缩回路400、400′。蒸汽压缩回路400、400′包括压缩机402、第一热交换器404、膨胀设备406、406′、第二热交换器408、排出管线412、旁路管线419、419′和控制器490。排出管线412从压缩机402的出口延伸到第一热交换器404的入口。蒸汽压缩回路400、400′被配置为在加热模式620下操作,在加热模式620下,第一热交换器404作为冷凝器操作,并且第二热交换器408作为蒸发器操作。蒸汽压缩回路400、400′还被配置为在解冻模式610下操作,在解冻模式610下,工作流体经由旁路管线419、419′和膨胀设备406、406′从压缩机402被引导612至第二热交换器408,旁路管线419、419′从排出管线412延伸以绕过第一热交换器404。
