Document Type and Number:
WIPO Patent Application WO/2019/151115
Kind Code:
A1
Abstract:
Provided is a heat source unit of a refrigeration device provided with a heat exchanger in which heat exchange units having a plurality of stages of flat tubes are arranged side by side in a plurality of rows, and gas-side headers are arranged in the heat exchange units on the downstream side in the air flow direction, the heat source unit being capable of suppressing frost formation on the gas-side headers. The heat source unit of an air-conditioning device is provided with: a heat source-side fan; a heat source-side heat exchanger (11) including heat exchange units (50) which have a plurality of stages of flat tubes and are arranged side by side in a plurality of rows in the air flow direction of air generated by the heat source-side fan; and a casing that accommodates the heat source-side fan and the heat source-side heat exchanger. The plurality of heat exchange units include a leeward-side heat exchange unit (50b) and a windward-side heat exchange unit (50a). The leeward-side heat exchange unit has a second header (80) which is provided with a gas refrigerant inlet/outlet and to which the flat tubes of the leeward-side heat exchange unit is connected. The second header is disposed at a position that comes into contact with the air that has exchanged heat with the refrigerant flowing through the flat tubes of the windward-side heat exchange unit.
