Abstract

The invention discloses a drifting detection method for a temperature sensor in an outdoor unit heat exchanger, a processor and an air conditioner. The method comprises the steps that when the air conditioner is in a startup state, the pressure values, collected by pressure sensors, of refrigerating fluid in an air conditioner pipeline are received, and the temperature value collected by the temperature sensor in the outdoor unit heat exchanger is received; based on the received pressure values, the saturation temperature values corresponding to the pressure values are determined, and the absolute value of the difference between the received temperature value and the saturation temperature values is determined; and whether the absolute value is larger than a preset drifting temperature difference value or not is judged, and if yes, it is determined that the temperature sensor in the outdoor unit heat exchanger drifts. When the air conditioner is in the startup state, the pressure values of the refrigerating fluid in the air conditioner pipeline are obtained, and therefore whether the absolute value of the difference between the temperature value collected by the temperature sensor in the outdoor unit heat exchanger and the saturation temperature values corresponding to the pressure values is larger than the drifting temperature difference value or not can be judged, then whether the temperature sensor drifts or not can be determined, and the problem that an existing air conditioner cannot detect drifting of a temperature sensor is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for detecting drift of a temperature sensor in a heat exchanger of an outdoor unit, a processor and an air conditioner. Background technique [0002] The temperature sensor in the heat exchanger of the outdoor unit of the existing air conditioner plays an important role. The temperature value collected by the temperature sensor is the data basis for the defrosting control and high temperature protection of the air conditioner. Therefore, the temperature sensor in the heat exchanger of the outdoor unit Whether a fault occurs will directly affect the operation of the air conditioner. [0003] Existing air conditioners only have a device for alarming the on-off failure of the temperature sensor in the heat exchanger of the outdoor unit. Has the above functions. [0004] However, the failure of the temperature sensor in the heat exchanger of the outdoor unit inclu...
