摘要： PROBLEM TO BE SOLVED: To promptly dissolve a differential pressure before and after a refrigerant flow passage of an indoor solenoid valve when changing over an operation mode from reheating dehumidifying operation to cooling operation, to cretainly perform solenoid valve changeover operation in a short time. SOLUTION: When changing over the indoor solenoid valve 30 so as to perform the changeover from the reheating dehumidifying operation to the cooling operation, an indoor decompressor 26 is fully closed only for a prescribed time so as to dissolve the differential pressure before and after the indoor solenoid valve. Thereby, because the differential pressure before and after the solenoid valve can be done away with without stopping a compressor 21, the indoor solenoid valve can be promptly changed over, so that a stop time of air conditioning operation when changing over the operation mode of an indoor machine from the reheating dehumidifying operation to the cooling operation can be made to be shortest, and comfort is not sacrificed.
