AIR-CONDITIONING UNIT, HEAT EXCHANGER, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/002288
Kind Code:
A1
Abstract:
Provided are a heat exchanger that makes it possible to supply air of an appropriate temperature to a plurality of blowing ports of an air-conditioning unit, an air-conditioning unit that comprises the heat exchanger, and an air conditioner. This air-conditioning unit 10 comprises a heat exchanger 20 that exchanges heat between air and a coolant, a blower 11, and an air outflow part 12. The heat exchanger 20 comprises a plurality of tubes 21 in which the coolant flows, an inlet header 23, an outlet header 24, and a fin 22. The inlet header 23 includes: a low-temperature-side coolant inflow part 231 into which coolant that has a relatively low temperature can flow; and a high-temperature-side coolant inflow part 232 into which coolant that has a relatively high temperature can flow. The low-temperature-side coolant inflow part 231 and the high-temperature-side coolant inflow part 232 are offset from each other in the direction D1 of the flow of air that passes through the heat exchanger and in an intersecting direction D2 that intersects the direction D1 of the flow of air.
