Title:
VEHICLE AIR CONDITIONING SYSTEM, HEAT MANAGEMENT SYSTEM AND CONTROL METHOD THEREFOR, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/208175
Kind Code:
A1
Abstract:
A vehicle air conditioning system, a heat management system (1) and a control method therefor, and a vehicle (5). The heat management system (1) comprises: one or more heat exchange loops (2), each heat exchange loop (2) comprising a heat pump device (21), a heat absorption heat exchanger (22) and a heat supply heat exchanger (23) which are sequentially connected in series, when there are a plurality of heat exchange loops (2), the plurality of heat exchange loops (2) sharing the heat pump device (21), the heat absorption heat exchanger (22) comprising at least one of an in-vehicle heat exchanger (221) and a battery pack heat exchanger (222), and the heat exchange loops (2) being used for implementing in-vehicle warming or battery pack heating; and a valve assembly (3), used for implementing on/off of each heat exchange loop (2), wherein when the heat absorption heat exchanger (22) is the in-vehicle heat exchanger (221), the heat supply heat exchanger (23) comprises at least one of the battery pack heat exchanger (222), an out-vehicle heat exchanger (223), and a motor electric control assembly heat exchanger (224); when the heat absorption heat exchanger (22) is the battery pack heat exchanger (222), the heat supply heat exchanger (23) comprises at least one of the out-vehicle heat exchanger (223) and the motor electric control assembly heat exchanger (224).
