Abstract

[Object] In a fluid supply system which includes a plurality of heat pump units having a compressor and which supplies a fluid heated or cooled by the heat pump units to a fluid-using device, to control the operation unit count of heat pump units efficiently without grasping the air-conditioning capacities of the heat pump units.
[Means of Solution] The operation frequency of the compressor provided to a predetermined heat pump unit of the plurality of heat pump units is acquired. Whether or not to operate, other than the predetermined heat pump unit of the plurality of heat pump units, remaining heat pump units is determined depending on the operation frequency acquired.
