Title: AIR CONDITIONER HEATING CONTROL METHOD
Abstract:
An air conditioner heating control method. The method comprises: an air conditioner carrying out a heating operation, acquiring an indoor temperature, and comparing same with a first indoor temperature threshold value; if the indoor temperature is not greater than the first indoor temperature threshold value, carrying out fuzzy control over the following: 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 obtain a first target frequency; acquiring a coil temperature of an indoor heat exchanger, and if the coil temperature is greater than a 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, and controlling the compressor of the air conditioner; and determining a target coil temperature according to the indoor temperature, and satisfying a negative correlation between the target coil temperature and the indoor temperature. The air conditioner heating control method can solve the problem of heating being uncomfortable due to the fact that existing air conditioners are slow to provide heating.
