PROBLEM TO BE SOLVED: To early find refrigerant omission by relatively easily enhancing refrigerant omission detection accuracy, to thereby protect a compressor or the like.SOLUTION: During operation or stopping of an air conditioner, detection operation is forcibly started according to a request from a user, the operation of the air conditioner is fixed to an air flow reduction detection condition to execute air flow reduction detection, and then the operation of the air conditioner is fixed to a refrigerant omission detection condition to execute refrigerant omission detection. Consequently, capacity deterioration due to refrigerant omission can be identified with high accuracy, and refrigerant omission can be early found, thereby to protect a compressor or the like. |
