Abstract
A method for controlling the heating operation of an air conditioner. The method comprises: an air conditioner executing a heating operation, and acquiring an indoor temperature; if the indoor temperature is not greater than the first indoor temperature threshold value, executing fuzzy control; according to the difference in temperature between the indoor temperature and a set target indoor temperature, carrying out room temperature PID calculation so as to acquire a first target frequency; acquiring a coil temperature of an indoor heat exchanger, and if the coil temperature is greater than a set target coil temperature, determining the first target frequency to be an indoor unit frequency; otherwise, increasing the current operation frequency of a compressor so as to obtain a second target frequency, selecting the larger value of the first target frequency and the second target frequency, and determining the larger value to be the indoor unit frequency; controlling the compressor of the air conditioner according to the indoor unit frequency; and while executing dual PID control, according to the coil temperature, controlling electrical heating. Further disclosed is an apparatus fo…
