Problems solved by technology
However, since the air conditioner (whole unit) cannot receive the abnormal feedback signal from the fan, during the start-up and operation of the compressor, if the fan motor stops abnormally, the whole unit cannot stop immediately to protect the compressor, but continues to run for a period of time. Time until the compressor overload protection
During this process, the pressure on the side of the condenser continues to increase, and the power of the compressor and the exhaust temperature continue to rise. Therefore, there are certain safety hazards in the whole machine, and it also damages the life of the compressor.

The invention discloses an air conditioner protection method and an air conditioner protection device. The air conditioner protection method includes that recording, to be specific, recording the temperature of a thermal bulb of an evaporator of an air conditioner and the running power of the air conditioner corresponding to the temperature when a compressor of the air conditioner starts refrigerating and / or refrigerates normally; calculating, to be specific, calculating the temperature variation of the temperature in a preset time period and the power variation of the running power in the preset time period; judging, to be specific, judging whether an outdoor fan of the air conditioner runs abnormally according to the temperature variation and power variation; processing, to be specific, when the outdoor fan runs abnormally, stopping the running of the compressor, and re-starting the compressor after a preset time. By means of the technical scheme of the air conditioner protection method and air conditioner protection device, when the outdoor fan runs abnormally, the air conditioner can be turned off immediately to protect the air conditioner, the life span of the compressor is prolonged, and the potential safety hazard of the air conditioner is lowered.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner protection method and an air conditioner protection device. Background technique [0002] An air conditioner is generally composed of an indoor unit, an outdoor unit, a compressor, and an outdoor fan motor. The indoor unit is connected to a liquid pipe through a gas pipe to form a circulation loop. It can only protect itself, and there is no feedback to the whole machine when it is running abnormally. In this way, once the fan fails, the whole system will still run until the compressor is overloaded. [0003] During the cooling operation of the air conditioner, the fan makes the condenser and the air produce strong convective heat exchange, which greatly enhances the heat exchange capacity of the heat exchanger and reduces the condensation pressure on the refrigerant side. However, since the air conditioner (whole unit) cannot receive the abnormal fee...
