PROBLEM TO BE SOLVED: To provide an air conditioner 10 capable of accurately determining the finish of ice melting operation, regardless of whether or not refrigerant leakage is caused in an expansion valve 52. SOLUTION: The refrigerant leakage in the expansion valve 52 is guessed from a detecting result of high-low pressure difference detecting means 93 and 97 for detecting a high-low pressure difference in a refrigerating cycle. A control means 81 sets the reference temperature T3 to a value corresponding to a degree of the refrigerant leakage in the expansion valve 52 on the basis of the detecting result of the high-low pressure difference detecting means 93 and 97.
