Gas concentration correction method and device for air conditioner

The invention discloses a gas concentration correction method and device for an air conditioner. The gas concentration correction method for the air conditioner comprises the steps that the gas concentration value at the current time is obtained; and in a preset time period after the operation state of the air conditioner is switched, the gas concentration value is corrected based on the gas concentration difference value, the temperature difference value or the humidity difference value between the current time and the last time, and a corrected concentration value is obtained. The output accuracy of the sensor can be improved. 本申请公开了一种用于空调的气体浓度修正方法及装置。其中，该用于空调的气体浓度修正方法包括：获取当前时间的气体浓度值；在空调切换运行状态后的预设时间段内，基于当前时间和上一时间之间的气体浓度差值、温度差值或湿度差值对所述气体浓度值进行修正，得到修正浓度值。本申请可以提高传感器输出准确性。
