Title
(EN) Heat pump system
(ZH) 一种热泵系统
Abstract
(EN) The embodiment of the invention discloses a heat pump system and belongs to the technical field of heat pump units. The heat pump system comprises an electromagnetic suspension centrifugal compressor,and further comprises a switching communication device and a first electric valve; an exhaust pipe of the electromagnetic suspension centrifugal compressor is connected to a first interface of the switching communication device through a first one-way valve, and a suction pipe is connected to a third interface of the switching communication device; and the first electric valve is arranged in parallel with the electromagnetic suspension centrifugal compressor. By adopting the heat pump system, the heating function of an electromagnetic suspension centrifugal compressor unit is realized via theswitching communication device; meanwhile, the arranged first electric valve is opened before starting of the electromagnetic suspension centrifugal compressor and is used for adjusting the pressuredifference of a high pressure side and a low pressure side of the compressor; and the arranged first electric valve is opened before closing of the compressor and is used for reducing the shutdown pressure ratio so that the compressor can run smoothly.
(ZH) 本发明实施例公开了一种热泵系统,属于热泵机组技术领域。该热泵系统包括磁悬浮离心压缩机,还包括切换连通装置和第一电动阀;该磁悬浮离心压缩机的排气管通过第一单向阀连接该切换连通装置的第一接口,吸气管连接该切换连通装置的第三接口;该第一电动阀与磁悬浮离心压缩机并联设置。采用上述可选实施例,通过切换连通装置实现磁悬浮离心压缩机机组的制热功能;同时,通过设置第一电动阀,在该磁悬浮离心压缩机的启动前开启,用于调整压缩机高低压侧的压差;在压缩机关闭前开启,用于降低停机压比,使得压缩机能够平稳运行。
