Example Embodiment
[0037] The control method of the present invention can be used to defrost the fixed frequency air conditioner. Specifically, the air conditioner has a heating mode and a defrosting mode that is activated after meeting a preset trigger condition when the air conditioner works in the heating mode.
[0038] figure 1 It is a schematic flowchart of a control method according to an embodiment of the present invention. See figure 1 , Control methods include:
[0039] Step S100, the air conditioner enters the heating mode for the nth time.
[0040] Step S102, detecting the coil temperature of the heat exchanger in the air-conditioning room.
[0041] In step S104, it is determined whether the air conditioner meets the preset trigger condition; if so, step S106 is executed, and if not, step S102 is returned to continue.
[0042] Step S106, the air conditioner enters the defrosting mode for the mth time, obtains the heating mode time Sy for the entire process of running the nth heating mode, and ob
