Embodiment Construction
[0032] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] This embodiment proposes an overheat protection control method for an air conditioner, which judges whether the air conditioner is in a dirty state by the current of the whole machine, and controls the shutdown of the air conditioner when the air conditioner is in a dirty state; The relationship between the absolute value of the difference with the set value of the indoor coil and the set threshold determines whether the indoor coil temperature sensor fails, and when the indoor coil temperature sensor fails, the operating status of the fan and compressor is controlled by the current of the whole machine .
[0034] Specifically, the overheating protection control method of the air conditioner in this embodiment is as follows:
[0035] The indoor temperature sensor detects the indoor temperature, the o...
