METHOD FOR REGULATING EVAPORATION TEMPERATURE OF INDOOR UNIT OF AIR CONDITIONER, AND AIR CONDITIONER

WIPO Patent Application WO/2019/033998

A1

A method for regulating the evaporation temperature of an indoor unit (1) of an air conditioner, and the air conditioner. The method comprises the following steps: determining whether the ambient temperature at where the indoor unit (1) is located is greater than or equal to a dew point temperature; if the ambient temperature is less than the dew point temperature, then reducing the degree of openness of a first throttling element (12) arranged on a liquid pipe (11) of the indoor unit (1), thus reducing the volume of a liquid refrigerant entering a heat exchanger (3) of the indoor unit (1); if the ambient temperature is greater than or equal to the dew point temperature, then reducing the degree of openness of a second throttling element (14) arranged on a gas pipe (13) of the indoor unit (1), thus reducing the outflow speed of a gaseous refrigerant from the gas pipe (13). The regulation of the evaporation temperature of the indoor unit (1) is implemented by regulating the degree of openness of the first throttling element (12) and that of the second throttling element (14), thus satisfying different demands for cooling and dehumidification in different rooms.
