Air conditioner and heating control method thereof

Abstract

The invention discloses an air conditioner, which includes a compressor, an indoor fan, an indoor temperature sensor, an air outlet temperature sensor, a PTC electric heater and a controller; wherein, the indoor temperature sensor is used to collect the indoor environment when the air conditioner heating mode starts The real-time temperature is output to the controller; the air outlet temperature sensor is used to collect the actual air outlet temperature of the air conditioner when the air conditioner heating mode is started and output to the controller; the controller is used to: according to the pre-stored comfortable outlet air temperature-ambient temperature change curve Calculate the comfortable outlet temperature with the real-time temperature of the indoor environment, and compare the difference △T between the actual outlet temperature and the comfortable outlet temperature. When △T exceeds the threshold, control the working state of the PTC electric heater so that △T is at within the threshold range. The invention also discloses a heating control method of the air conditioner. The present invention can realize rapid heating up and wind-out comfort, and has simple structure and sensitive response.

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...
