Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/049879
Kind Code:
A1
Abstract:
This air conditioning device comprises a refrigerant circuit and a control unit. The refrigerant circuit includes an indoor heat exchanger (13) having a first section on the windward side and a second section on the leeward side of the first section. The control unit causes the indoor heat exchanger (13) to be cleaned by setting the first section to serve as an evaporation region after a heating operation. The control unit controls the temperature of a refrigerant flowing through the indoor heat exchanger (13) such that the refrigerant temperature becomes equal to or lower than the dew point temperature of indoor air passing through the indoor heat exchanger (13) in the first section, and the refrigerant temperature becomes higher in the second section than in the first section.
