Abstract

A control method for a heating system of an air conditioner, the method includes: obtaining ambient temperature and external heat exchanger evaporation temperature; obtaining external heat exchanger evaporation pressure, and obtaining, according to the external heat exchanger evaporation pressure, corresponding saturation temperature; and controlling a base plate heating device according to the ambient temperature, the external heat exchanger evaporation temperature, or the saturation temperature. The base plate heating device is controlled according to the ambient temperature, the saturation temperature corresponding to the external heat exchanger evaporation pressure, or the external heat exchanger evaporation temperature, and may avoid freezing of the base plate of an air conditioner, and may ensure normal drainage of the base plate during defrosting to improve the stability and reliability of the air conditioner.
