摘要： A heat source device is provided with a differential pressure sensor that measures the differential pressure between an inlet pressure and an outlet pressure for the chilled water in an evaporator and with a control device. The control device possesses the coefficient of loss for the evaporator and is provided with a chilled-water flow-rate computing portion that calculates a chilled-water flow rate at the evaporator on the basis of the coefficient of loss and the differential pressure output from the differential pressure sensor; a control-command computing portion that generates a control command by using a specification heating-medium flow rate that is set in advance; and a control-command correcting portion that corrects the control command generated by the control-command computing portion.

摘要： Provided is a heat source system that includes two heat source devices connected in series to a heat medium and can be efficiently operated. A heat source system (1) reduces the temperature of chilled water that is guided from a cooling load and has a predetermined return temperature Tr, to a predetermined supply temperature Ts, and supplies the chilled water to the cooling load. The heat source system (1) includes: a second centrifugal chiller (TR2) that reduces the temperature of the chilled water from the return temperature Tr to an intermediate temperature T2; a first centrifugal chiller (TR1) that reduces the temperature of the chilled water that has been reduced to the intermediate temperature T2 by the second centrifugal chiller (TR2), to the supply temperature Ts; and a control unit (9) that variably sets the intermediate temperature T2.
