Title:
HEAT PUMP AIR CONDITIONING SYSTEM AND ELECTRIC AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2017/193853
Kind Code:
A1
Abstract:
A heat pump air conditioning system, the system comprising: an indoor condenser (601), an outdoor evaporator (602), a compressor (604), and an outdoor heat exchanger (605), an outlet of the compressor (604) being connected to an inlet of the indoor condenser (601), an outlet of the indoor condenser (601) being connected to an inlet of the outdoor heat exchanger (605) selectively via a first throttle branch or a first through-flow branch, an outlet of the outdoor heat exchanger (605) being connected to a first end of a selectively open or closed off second branch (621) selectively via a second throttle branch or a second through-flow branch, a second end of a first branch (620) being connected to an inlet of the compressor (604), a second end of the second branch (621) being connected to an inlet of the indoor evaporator (602), an outlet of the indoor evaporator (602) being connected to an inlet of the compressor (604), an outlet of the indoor condenser (601) also being connected to an inlet of the compressor (604) via a selectively open or closed off third throttle branch, and an outlet of the outdoor heat exchanger (605) also being connected to an inlet of the compressor (604) via a selectively open or closed off fourth throttle branch. Also disclosed is an electric automobile comprising said heat pump air-conditioning system. The present system achieves the effects of improving heating energy efficiency, satisfying the requirements of defrosting and demisting regulations, and being easy to install.
