Title:
AIR CONDITIONER AND AIR CONDITIONER CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/098317
Kind Code:
A1
Abstract:
An air conditioner and an air conditioner control method, which relate to the technical field of air conditioners. The air conditioner comprises: a refrigerant main circuit, the refrigerant main circuit comprising: a compressor (101), a gas-liquid separator (102), an outdoor heat exchanger (103), and an indoor heat exchanger (104); a first heating branch, which heats a liquid refrigerant discharged by the gas-liquid separator (102) into a gaseous refrigerant, and sends same to a suction port of the compressor (101); a shunting and regulating branch, which shunts and regulates a refrigerant flowing from the indoor heat exchanger (104) to the outdoor heat exchanger (103); a second heating branch, which receives the refrigerant delivered by the shunting and adjusting branch, heats same, and then sends same to the suction port by means of the first heating branch; a first enthalpy increasing branch, which receives the refrigerant that is heated by the second heating branch, and sends same to an enthalpy increasing port of the compressor (101); and a second enthalpy increasing branch, which receives the refrigerant delivered by the shunting and adjusting branch, carries out heat exchange with the refrigerant in the refrigerant main circuit so as to absorb the heat of the refrigerant main circuit refrigerant, and then sends same to the enthalpy increasing port. The present invention helps to improve the indoor heating effect of an air conditioner.
