The invention discloses an air conditioner and a protection method thereof. The air conditioner comprises an indoor unit coil temperature sensor, an indoor fan motor and an indoor unit controller, wherein the indoor unit coil temperature sensor is used for measuring the temperature of an indoor unit coil; the indoor fan motor is used for generating air flow of indoor air passing through an evaporator during operation so as to promote heat exchange between the evaporator and the indoor air; the indoor unit controller is connected with the indoor unit coil temperature sensor and the indoor fan motor, and the indoor unit controller is used for receiving indoor unit coil temperature measured by the indoor unit coil temperature sensor after the air conditioner is shut down; whether an anti-freezing protection condition is met or not is judged according to the indoor unit coil temperature; and when it is judged that the anti-freezing protection condition is met, the indoor fan motor is controlled to operate. According to the air conditioner and the protection method thereof, the air conditioner can be prevented from being damaged due to a large amount of freezing of the evaporator, and the durability and safety of the air conditioner are improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a protection method thereof. Background technique [0002] At present, low-cost fixed-speed air conditioners often adopt a single-board solution. The air conditioner using the single-board solution is characterized by only an internal unit controller and no external unit controller. The outdoor unit is completely controlled by the internal unit controller. Generally speaking, for an air conditioner that adopts a single-board solution, the control objects of the external unit mainly include the AC fan motor and the AC contactor used to control the start and stop of the compressor, and the control objects of the internal unit mainly include the indoor fan motor, which is used to control the AC contactor. The first relay for controlling the outdoor fan motor and the second relay for controlling the outdoor fan motor, wherein the controller of the indo...
