Title:
HEAT PUMP SYSTEM, CONTROL METHOD THEREFOR AND APPARATUS THEREOF, AND AIR CONDITIONING DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/105605
Kind Code:
A1
Abstract:
A heat pump system, a control method therefor and apparatus thereof, and an air conditioning device and a storage medium, which relate to the technical field of heat pumps. In the heat pump system: a valve assembly (001) is separately connected to an exhaust port and an air suction port of a compressor (01), a first end of a second indoor heat exchanger (09), and a first end of an outdoor unit (200); a second end of the second indoor heat exchanger (09) is connected to a second end of the outdoor unit (200); the valve assembly (001) is used for controlling the flow direction and on/off of a refrigerant to form a refrigerant loop; a first end of a first indoor heat exchanger (08) is connected to the exhaust port of the compressor (01), and the second end of the first indoor heat exchanger (08) communicates with a second connecting pipeline (003) between the second end of the second indoor heat exchanger (09) and the second end of the outdoor unit (200) by means of a first connecting pipeline (002); and a first control valve (06) is disposed in a pipeline between the first end of the first indoor heat exchanger (08) and the exhaust port of the compressor (01). The system, method, apparatus, the air conditioning device, and the storage medium do not require the use of an electric heating system, and can reduce the amount of energy consumption, improve the energy-saving performance, and improve the use experience of a user.
