Title:
INDOOR UNIT FOR AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/190121
Kind Code:
A1
Abstract:
[Problem] To suppress a reduction in the heat exchange amount between a refrigerant and air caused by pressure loss. [Solution] In this indoor unit for an air conditioner, a second heat exchange unit has a high air velocity region in which the air velocity of air passing through the second heat exchange unit is relatively high, and a low air velocity region in which the air velocity of air is relatively low, and the high air velocity region is positioned above the low air velocity region in the direction of gravity. At least one first heat transfer tube is disposed in the high air velocity region, and at least one second heat transfer tube is disposed in the low air velocity region. A first header is connected to each of the first heat transfer tube and the second heat transfer tube. The first header has a first internal space to which the first heat transfer tube and the second heat transfer tube are commonly connected. When using the heat exchanger as a condenser, the refrigerant flowing out from the first heat exchange unit 110 flows into the first internal space of the first head, and then the refrigerant flows into each of the first heat transfer tube and the second heat transfer tube from the first internal space.
