1. A support system that supports at least one of design or construction of a refrigerant cycle apparatus, the support system comprising:
a display; and
a server that comprises a storage and a processor that causes the display to display information, wherein
the refrigerant cycle apparatus comprises:
utilization-side units each comprising a first refrigerant circuit;
a heat source-side unit comprising a second refrigerant circuit;
a connection pipe group that connects the first refrigerant circuit and the second refrigerant circuit; and
a refrigerant shut-off unit that is disposed between the first refrigerant circuit and the second refrigerant circuit and that blocks a refrigerant flowing through the connection pipe group,
the utilization-side units comprising a first utilization-side unit group that is a group of N utilization-side units, wherein N is an integer equal to or more than two, wherein
the refrigerant shut-off unit comprises a first refrigerant shut-off unit that blocks a flow of the refrigerant between the first refrigerant circuit in the first utilization-side unit group and the second refrigerant circuit,
the first refrigerant shut-off unit is common to the group of N utilization-side units constituting the first utilization-side unit group,
the connection pipe group comprises a first connection pipe group that connects the first refrigerant circuit in the first utilization-side unit group and the first refrigerant shut-off unit,
the storage stores first information on arrangement of the first refrigerant shut-off unit, second information on each of the utilization-side units in the first utilization-side unit group, and third information on one of or both a length and an internal volume of the first connection pipe group,
the processor acquires, from the storage, the first information, the second information, or the third information,
when the processor acquires the first information, the second information, and the third information, the processor:
determines, based on an allowable refrigerant leak amount of the refrigerant into a space where a corresponding one or more utilization-side units in the first utilization-side unit group is installed, whether the first information, the second information, and the third information are suitable for at least one of the design or the construction of the refrigerant cycle apparatus and causes the display to display a result of the determination; or
calculates a first refrigerant amount and causes the display to display the first refrigerant amount,
the first refrigerant amount that is a sum of a second refrigerant amount in the first refrigerant circuit in the first utilization-side unit group and a third refrigerant amount in the first connection pipe group, and
a number of utilization side units in the first utilization-side unit group is less than a total number of the utilization-side units in the refrigerant cycle apparatus.
