Abstract (en)
[origin: EP3988871A1] An outdoor unit (2) includes: a heat exchanger (40); and a receiver (30). The heat exchanger (40) exchanges heat between refrigerant flowing in a first passage (HI) and the refrigerant flowing in a second passage (H2). The receiver (30) is disposed between a condenser (20) and the first passage (HI) of the heat exchanger (40), and stores the refrigerant. A load device (3) and a flow path from a compressor (10) to the first passage (HI) of the heat exchanger (40) via the condenser (20) and the receiver (30) form a circulation flow path through which the refrigerant circulates. The outdoor unit (2) further includes: a first refrigerant flow path (91); a second expansion valve (92); and a second refrigerant flow path (94). The first refrigerant flow path (91) causes the refrigerant to flow from the receiver (30) or an outlet pipe of the receiver (30) on the circulation flow path to an inlet of the second passage (H2). The second refrigerant flow path (94) causes the refrigerant to flow from an outlet of the second passage (H2) to the compressor (10).
