Beschreibung
Zusammenfassung:	The invention discloses a PTC heating type air conditioner heating control method and device. The PTC heating type air conditioner heating control method comprises the steps that the temperature set by a user is obtained, and the current environment temperature is obtained; the required power of the current PI according to the current environment temperature and the user set temperature are calculated, and the reference duty ratio of the required power is calculated through a constant power algorithm; the current PI controls the PWN to output a reference duty ratio so as to control the current heating power of a PTC heater; and after the PTC heater operates for one unit of heating time at the current heating power, the current environment temperature is obtained again, and the heating power of the PTC heater is adjusted. According to the PTC heating type air conditioner heating control method, the influence of curve change of the resistance caused by the change of the PTC along with the temperature can be avo
