Title:
HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/007739
Kind Code:
A1
Abstract:
The present application provides a heat pump system. The heat pump system comprises a main circulating refrigerant loop, an auxiliary circulating refrigerant loop, and a refrigerant management system; the main circulating refrigerant loop comprises a main compressor, a first main heat exchanger, a main throttling device, and a second main heat exchanger; the main compressor is configured to allow a refrigerant in the main circulating refrigerant loop to circulate in a main circulating refrigeration working condition flow direction or circulate in a main circulating heating working condition flow direction. The auxiliary circulating refrigerant loop comprises an auxiliary compressor, a first auxiliary heat exchanger, an auxiliary throttling device, and a second auxiliary heat exchanger; the auxiliary compressor is configured to allow a refrigerant in the auxiliary circulating refrigerant loop to circulate in an auxiliary circulating heating working condition flow direction. The refrigerant management system is controllably connected to or disconnected from the main circulating refrigerant loop and the auxiliary circulating refrigerant loop, separately; the refrigerant management system is configured to be capable of distributing a refrigerant used for the main circulating refrigerant loop to the auxiliary circulating refrigerant loop. Less refrigerant is used in the heat pump system provided by the present application.
