Control method and device of air conditioner, storage medium and air conditioner

Abstract

The invention discloses a control method and device of an air conditioner, a storage medium and the air conditioner. The method includes the steps that the frosting amount of an outdoor heat exchangerof the air conditioner is determined, wherein the frosting amount of the outdoor heat exchanger comprises the frost layer thickness of the outdoor heat exchanger; if the frost layer thickness of theoutdoor heat exchanger belongs to a set defrosting frost layer thickness range, the air conditioner is controlled to be switched into a defrosting manner from a heating manner; if the frost layer thickness of the outdoor heat exchanger belongs to a set non-defrosting frost layer thickness range, the heat comfort state of an indoor environment of the air conditioner is determined; and the air conditioner is controlled to continue to be subjected to heating operation in the heating manner according to the heat comfort state of the indoor environment or be switched into the defrosting manner fromthe heating manner. By means of the scheme, the problems that whether defrosting is carried out or not is judged according to the temperature of the outdoor heat exchanger or the difference between the temperature of the outdoor heat exchanger and the temperature of an outdoor environment, when defrosting exists, the indoor temperature drop is large, and therefore the defrosting heat comfort is poor can be solved, and the effect of improving the defrosting heat comfort is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner control method, device, storage medium and air conditioner, in particular to an air conditioner control method, device, storage medium and air conditioner based on indoor thermal comfort. Background technique [0002] When some heat pump air conditioners are in heating operation, when the temperature of the outdoor heat exchanger is lower than the dew point temperature of the humid air and the temperature of the outdoor heat exchanger is lower than 0°C, the water vapor in the air will condense into frost on the surface of the outdoor heat exchanger Floor. The frost layer will increase the thermal resistance of the outdoor heat exchanger, causing the heating capacity to attenuate. In order to ensure the heating performance, when the frost layer grows to a certain extent, it is necessary to defrost the outdoor heat exchanger. But some defro...
