Description

Anti-freezing control method, storage medium, electronic equipment and air conditioner Technical Field The invention relates to the technical field of air conditioners, in particular to an anti-freezing control method, a storage medium, electronic equipment and an air conditioner. Background In the winter heating process of the air conditioner, the low-temperature refrigerant absorbs heat when passing through the outdoor heat exchanger, at the moment, water molecules in the outdoor humid air can be separated out and frosted on the surface of the outdoor heat exchanger, and in addition, the air conditioner can be easily frozen in areas with long winter time, more wind and snow and relatively wet cooling, so that the heat exchange efficiency of the outdoor heat exchanger is affected, and the heating efficiency of the air conditioner is reduced. In this regard, defrosting is generally achieved by cooling operation after a certain period of heating operation of the air conditioner, i.e., the high-temperature refrigerant is first introduced into the outdoor heat exchanger to release heat, and at this time, the frost on the surface of the outdoor heat exchanger is melted into water and discharged through a water outlet on the chassis of the air conditioner. However, the defrosting mode cannot accurately judge the frosting condition of the surface of the outdoor heat exchanger, so that energy waste or heating efficiency reduction can be caused. In addition, the melted water may be frozen due to the too low temperature of the chassis, thereby causing unsmooth drainage and reduced heating efficiency. Accordingly, there is a need in the art for a new solution to the above-mentioned problems. Disclosure of Invention In order to solve at least one of the above problems in the prior art, that is, in order to solve the problems of poor anti-freezing effect and low heating energy efficiency of the existing air conditioner, the present application provides an anti-freezing control method for an air conditioner, wherein the air conditioner comprises an air conditioner external unit and an air conditioner internal unit, the air conditioner external unit comprises an outdoor heat exchanger and a heating module, a defrosting sensor is arranged at an outlet of the outdoor heat exchanger, and at least part of the heating module is arranged on a chassis of the air conditioner external unit, the anti-freezing control method comprises: acquiring an ambient temperature and an outlet temperature of the outdoor heat exchanger; determining an outlet temperature threshold based on the ambient temperature; Judging the magnitude of the outlet temperature and the outlet temperature threshold; And selectively controlling the air conditioner to operate in a defrosting mode and the heating module to be started based on a judging result. Under the condition of adopting the technical scheme, firstly, whether a defrosting mode needs to be started or not is favorably determined accurately through the ambient temperature and the outlet temperature of the outdoor heat exchanger, when the defrosting mode is started by the air conditioner, frost on the outdoor heat exchanger is melted into water and then drops onto the chassis of the air conditioner outdoor unit, and a heating module on the chassis is also in a starting state, so that original ice on the chassis can be removed on one hand, and on the other hand, defrosting water can be prevented from being frozen on the chassis, thereby ensuring the drainage effect of the chassis and the heat exchange efficiency of the outdoor heat exchanger. In the above preferred technical solution of the antifreeze control method, selectively controlling the operation defrost mode of the air conditioner and the start of the heating module based on the determination result further includes: and when the outlet temperature is less than or equal to the outlet temperature threshold, controlling the air conditioner to operate in a defrosting mode and the heating module to be started.
