Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2020153646
Kind Code:
A
Abstract:
To provide an air conditioner enabling dehumidification while performing strong heating by a heating cycle without deteriorating air-conditioning capacity other than the dehumidification operation by the heating cycle.SOLUTION: An air conditioner includes a refrigerant circuit (RC) in which a refrigerant circulates and a control section (100) controlling the refrigerant circuit (RC). An indoor heat exchanger (11) includes a refrigerant passage in which a refrigerant flows and a control valve (13) provided in the middle of the refrigerant passage. When a dehumidification operation is performed by a heating cycle, the control section (100) controls the control valve (13) and decompresses the refrigerant by using the control valve (13) so that portions (11a, 11b, 11c, 11e) on the upstream side of the control valve (13) in the indoor heat exchanger (11) serve as condensation regions and a portion (11d) on the downstream side of the control valve (13) in the indoor heat exchanger (11) serves as an evaporation region. The approximately entire evaporation region is provided in a part of windward sides of the condensation regions.SELECTED DRAWING: Figure 1
