Abstract (en)
[origin: EP3136013A1] A heat pump chilling system includes an inlet temperature sensor that detects an inlet temperature of a heat medium flowing into a plurality of heat pump chilling devices, an outlet temperature sensor that detects an outlet temperature of flow from the plurality of heat pump chilling devices to a load, and a system control device that controls operation of the plurality of heat pump chilling devices based on the inlet temperature and the outlet temperature. The system control device includes a storage unit that stores an operating capacity for each of the plurality of heat pump chilling devices, a requested-capacity calculating unit that calculates a requested capacity based on the inlet temperature or the outlet temperature and a set target temperature, a number-of-devices calculating unit that calculates the number of devices to be activated among the plurality of heat pump chilling devices satisfying the requested capacity based on the operating capacity of each of the plurality of heat pump chilling devices, and an activation control unit that activates the plurality of heat pump chilling devices of the number of devices to be activated calculated in the number-of-devices calculating unit.
