Abstract (en)

[origin: EP3943842A1] The degree of freedom when a refrigerant cycle system is constructed in a building or the like is increased. A refrigerant cycle system (1) according to the present disclosure includes a refrigerant cycle, a first power feed unit (30a), a second power feed unit (30b), a first transmission line (41), and a second transmission line (42). The power feed unit feeds auxiliary power to a utilization unit of which a power source has been interrupted. The first transmission line (41) connects a heat source unit (10) and the first power feed unit (30a) to each other. The second transmission line (42) connects the first power feed unit (30a) and the second power feed unit (30b) to each other. The second power feed unit (30b) is connected to the heat source unit (10) via the first power feed unit (30a).
