Abstract
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.
