Title: METHOD AND APPARATUS FOR CONTROLLING HEATING OPERATION OF AIR CONDITIONER
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 for controlling the heating operation of an air conditioner. By means of the method and apparatus, the problem of heating being uncomfortable due to the fact that existing air conditioners are slow to provide heating can be solved.
