Document Type and Number:
WIPO Patent Application WO/2022/209739
Kind Code:
A1
Abstract:
A heat source unit (10) connected to usage units (50, 60) is provided with compressors (22, 23), a first heat exchanger (13), a first expansion valve (14), and a receiver (15). In addition, the heat source unit (10) is provided with a first cooler (16) and a second cooler (155). The first cooler (16) cools a primary refrigerant flowing from the receiver (15) toward the usage units (50, 60). The second cooler (155) cools, by using a cooling medium other than outside air, the primary refrigerant flowing from the first heat exchanger (13) in a state of functioning as a heat radiator toward the first expansion valve (14).
