The invention provides a variable-angle electric heating control method and an air conditioner applying the variable-angle electric heating control method. At least two sections of heat exchangers arearranged in a surrounding mode, the included angle is smaller than 90 degrees, and electric heating is carried out under the driving of a stepping motor. The method comprises the following steps thatthe state of an electric heating switch is called, and if the electric heating switch works, the air supply temperature of an air outlet is collected; the air supply temperature difference between the air outlet air supply temperature and the air conditioner set temperature is calculated, and if the air supply temperature difference is smaller than the first set value, the stepping motor drives the electric heating switch to rotate to the first working position; and if the air supply temperature difference is larger than the first set value, the stepping motor drives the electric heating to rotate in sequence to the initial working position and keep the initial working position; and when the electric heating rotates to the first working position, the first heat dissipation surface of theelectric heating switch is kept horizontal, and when the electric heating device rotates to the initial working position, the first heat-dissipation surface and the second-section heat exchanger are parallel to each other. The method has the advantages of being high in flexibility and good in user experience.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a variable-angle electric heating control method and an air conditioner applying the method. Background technique [0002] When the air conditioner is running in heating mode, due to the low outdoor temperature, the heat exchange efficiency of the heat exchanger cannot meet the heating demand. In order to solve this problem, common air conditioners are equipped with PTC electric heating devices as auxiliary equipment to improve the heating effect. Existing electric heating device is made up of heat pipe, fin parts and reinforcing plate. In order to increase the heating power of the electric heating and increase the heat exchange area as much as possible, the electric heating adopts a structure design in which multiple rows of heating tubes and cooling fins are evenly distributed and extended in parallel. Since the length of the heating tube is much larger than the cros...
