PROBLEM TO BE SOLVED: To prevent a pressure increase caused by overheating of a refrigerant in delay operation of an indoor machine and a compressor after a combustion stop, and to prevent the generation of a problem in durability caused by a liquid compression state by carrying of the refrigerant supercooled by a compressor, in an air conditioner provided with a refrigerant heating device. SOLUTION: When the detection temperature of a heating refrigerant temperature sensor becomes an indoor blower stoppable temperature or below after stopping operation, the delay operation of the indoor machine is stopped when a detection temperature of a vaporization part temperature sensor is an indoor blower stop determination temperature or below, and the delay operation of an indoor blower is continued until the detection temperature falls to the indoor blower stop determination temperature when the detection temperature is higher than the indoor blower stop determination temperature. After stopping the operation, when the detection temperature of the heating refrigerant temperature sensor is the indoor blower stoppable temperature or below and when the detection temperature of the vaporization part temperature sensor is the indoor blower stop determination temperature or below, it is controlled such that the delay operation of the indoor blower is not performed.
