Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2016/117113
Kind Code:
A1
Abstract:
An air conditioner is equipped with a control unit that controls a refrigerant circuit switching device such that, during a first control period after a defrosting operation has been stopped, the rotational speed of a compressor is set lower than during the defrosting operation and the degree of opening of a decompression device is set to the same as or greater than the degree of opening during the defrosting operation, and during a second control period after the first control period has elapsed, the compressor is stopped, the degree of opening of the decompression device is set smaller than the degree of opening during the first control period, and the heating operation is restored after the elapse of the second control period. Thus, it is possible to suppress the generation of refrigerant noise from the decompression device after the defrosting operation has ended, and to reduce problems with the compressor due to a pressure difference when the heating operation is restored.
