Abstract

The degree of freedom when a refrigerant cycle system is constructed in a building or the like is increased. A refrigerant cycle system according to the present disclosure includes a refrigerant cycle, a first power feed unit, a second power feed unit, a first transmission line, and a second transmission line. The power feed unit feeds auxiliary power to a utilization unit of which a power source has been interrupted. The first transmission line connects a heat source unit and the first power feed unit to each other. The second transmission line connects the first power feed unit and the second power feed unit to each other. The second power feed unit is connected to the heat source unit via the first power feed unit.

Claims

exact text as granted — not AI-modified
1 . A refrigerant cycle system comprising:
 a refrigerant cycle including a heat source unit, a first utilization unit group, and a second utilization unit group;   a first power feed unit that differs from the heat source unit and, when a power source of each utilization unit of the first utilization unit group has been interrupted, feeds auxiliary power to the utilization unit of which the power source has been interrupted;   a second power feed unit that differs from the heat source unit and, when a power source of each utilization unit of the second utilization unit group has been interrupted, feeds auxiliary power to the utilization unit of which the power source has been interrupted;   a first transmission line that connects the heat source unit and the first power feed unit to each other; and   a second transmission line that connects the first power feed unit and the second power feed unit to each other,   wherein the second power feed unit is connected to the heat source unit via the first power feed unit.   
     
     
         2 . The refrigerant cycle system according to  claim 1 , wherein the heat source unit, the first power feed unit, and the second power feed unit are connected in series by the first transmission line and the second transmission line.
