Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/155685
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an air conditioner in which an increase in inside humidity is suppressed and drying of the interior of an indoor unit can be performed. This air conditioner has an outdoor unit, and an indoor unit having an indoor heat exchanger and a decompression device. The indoor heat exchanger has a first heat exchange unit and a second heat exchange unit, and the decompression device is connected between the first heat exchange unit and the second heat exchange unit. The air conditioner performs a cooling operation or dehumidifying operation in which the first heat exchange unit and the second heat exchange unit function as evaporators, and a reheating/dehumidifying operation in which the first heat exchange unit functions as a condenser and the second heat exchange unit functions as an evaporator. The second heat exchange unit is subjected to a treatment that imparts water-sliding properties. With this air conditioner, even if the reheating/dehumidifying operation is performed in which the second indoor heat exchange unit functions as an evaporator in order to dry the interior of the indoor unit, condensed water generated in the second indoor heat exchange unit on which the water-sliding treatment was performed is not retained in the second indoor heat exchange unit, and therefore drying of the interior of the indoor unit can be performed while suppressing an increase in indoor humidity.
