Air conditioner heating control method

The invention provides an air conditioner heating control method. An air conditioner has the heating mode. The air conditioner heating control method comprises the steps that when the air conditionerworks in the heating mode, after the air conditioner receives an instruction of starting the energy-saving function, the environment temperature Ti of the indoor environment where an indoor unit of the air conditioner is located is continuously detected, and according to the environment temperature Ti, the rotation speed n of an internal draught fan in the indoor unit and the frequency f of a compressor of an outdoor unit of the air conditioner are adjusted, wherein the rotation speed n of the internal draught fan is increased along with rising of the environment temperature Ti, and the frequency f of the compressor is reduced along with rising of the environment temperature Ti. By the adoption of the air conditioner heating control method, the rotation speed of the internal draught fan ofthe indoor unit is controlled to be correspondingly increased along with rising of the indoor temperature, the frequency of the compressor of the outdoor unit is controlled to be lowered along with rising of the indoor temperature, and therefore the indoor heat exchange air volume is increased; and in this way, the heat exchange pressure of the whole heat exchange system of the air conditioner inthe refrigeration process is lowered, the energy consumption of the compressor is lowered, and then the overall power of the air conditioner is lowered correspondingly.
