The application discloses an air conditioner and an air conditioner infrared target detection result stability enhancement method. The air conditioner comprises a refrigerant circulation loop, an outdoor heat exchanger and an indoor heat exchanger, an infrared thermopile sensor, a detected frame counter, an undetected frame counter and a controller. The controller is configured to: when the infrared image is detected as having a target, performing weighting processing on the cache frame weight based on a first count value, and outputting a target detection result and a target position coordinate. The first count value is the cumulative number of continuous detected frames of the infrared image. When the infrared image is detected as having no target and the infrared image is previously detected as having a target, outputting the target detection result and the target position coordinate based on a second counter. The second count value is the cumulative number of continuous undetected frames of the infrared image. The method realizes correction of the detected target according to the cache frame weight, improves the accuracy and stability of the detected target result, and improves the user experience.
