Air conditioner and heating control method thereof

Abstract

The invention discloses an air conditioner. The air conditioner comprises a compressor, an indoor draught fan, an indoor temperature sensor, an air outlet temperature sensor, a PTC electric heater and a controller, wherein the indoor temperature sensor is used for collecting and outputting indoor environment real-time temperature to the controller when an air conditioner heating mode is started; the air outlet temperature sensor is used for collecting and outputting actual air outlet temperature of the air conditioner to the controller when the air conditioner heating mode is started; the controller is used for working out the comfortable air outlet temperature according to the prestored comfortable outlet air temperature-environment temperature changing curve and the indoor environment real-time temperature and comparing the difference value delta T between the actual outlet air temperature and the comfortable air outlet temperature, and when the delta T exceeds the threshold, the controller controls the working state of the PTC electric heater to enable the delta T to be in the range of the threshold. The invention further discloses a heating control method of the air conditioner. According to the air conditioner and the heating control method of the air conditioner, fast temperature rise and air outlet comfort can be achieved, the structure is simple, and the reaction is sensitive.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a heating control method thereof. Background technique [0002] Existing heat pump air conditioners are generally equipped with an auxiliary electric heating device, which is used to supplement indoor heat under low temperature conditions, so as to accelerate the increase of indoor temperature. However, in an extremely low-temperature outdoor environment, the indoor temperature is not high, and the temperature of the blown air is very low in the first 5 to 6 minutes after starting up, which will make the user feel uncomfortable. Although some air conditioners have the function of anti-cold wind, the opening of the control of anti-cold wind is judged by the temperature in the middle of the evaporator, which often results in no blowing or the temperature of the blown air is too different from the comfortable temperature, which still makes the user fe...
