Control method for heating outlet air temperature of household air conditioner

The invention provides a control method for the heating outlet air temperature of a household air conditioner, and belongs to the field of heating outlet air control of a household air conditioner. Inorder to solve the problem that the outlet air temperature and outlet air speed of the ordinary household air conditioner fluctuate sharply under various conditions, the control method includes the steps that when the household air conditioner starts heating, an indoor inner coil pipe temperature is monitored; when the inner coil pipe temperature reaches a set temperature T1, an indoor direct-current motor is started to run at a rotating speed N1; an inner coil pipe temperature change rate, a current inner coil pipe temperature and a current indoor direct-current motor rotating speed parameter are monitored; when the current inner coil pipe temperature is less than or equal to T1, the indoor direct-current motor runs at the constant rotating speed N1, and when the current inner coil pipetemperature is greater tha
