Abstract

The invention discloses a temperature sensor drift detection method in a wind-side heat exchanger, a processor and an air conditioner. The method includes: when the air-conditioner is in a standby state, receiving the first temperature value collected by the temperature sensor in the wind-side heat exchanger, and receiving the ambient temperature The second temperature value collected by the sensor; determine the absolute value of the difference between the first temperature value and the second temperature value; determine whether the absolute value is greater than the preset drift temperature difference value, if greater, then determine the wind Drift of the temperature sensor in the side heat exchanger. It can be seen that, when the air conditioner is in the standby state, the present invention can determine whether the absolute value of the difference between the temperature value collected by the temperature sensor in the wind-side heat exchanger and the ambient temperature value is greater than the drift temperature difference by obtaining the ambient temperature value collected by the ambient temperature sensor. value, and then it can be determined whether the temperature sensor drifts, which solves the problem that the existing air conditioner cannot detect the drift of the temperature sensor.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a temperature sensor drift detection method in a wind-side heat exchanger, a processor and an air conditioner. Background technique [0002] The temperature sensor in the air side heat exchanger 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 air side heat exchanger Whether a fault occurs will directly affect the operation of the air conditioner. [0003] Existing air conditioners only have an alarm device for the on-off failure of the temperature sensor in the wind-side heat exchanger. This device will alarm when the temperature sensor in the wind-side heat exchanger has an infinite resistance value. Has the above functions. [0004] However, the faults of the te...
