Abstract

The present application relates to the air conditioning technical field, specifically provide a kind of electric heating control method, control device and air conditioner of duct type split air conditioner, to solve the problem that the electric heating control method of existing duct type split air conditioner cannot timely, accurately adjust room temperature.For this purpose, the control method of the present application includes: obtaining the real-time temperature and set temperature of each room;When the real-time temperature is lower than the set temperature, calculate the temperature difference value of each room according to the real-time temperature and the set temperature;According to the temperature difference value, determine the target room, and detect the temperature difference change rate of the target room;According to the temperature difference change rate, determine the heating load deficiency value of each target room, and calculate the average heating load deficiency value;According to the average heating load deficiency value, determine the working current value of the electric heating device and control the air volume of the indoor unit.The control method can timely and accurately adjust the temperature of multiple rooms.
