Abstract
A heating medium supply system (4) is provided which, even when a temperature fluctuation of a heating medium occurs continuously, is capable of relieving a bad thermal influence upon a heat exchanging device due to the temperature fluctuation. The heating medium supply system (4) includes: a heating system (6) configured to heat a liquid heating medium by sunlight; a heat exchanging device (7) configured to heat feedwater by means of the heating medium supplied thereto from the heating system (6); heating medium supply piping (8) for circulating the heating medium to the heating system (6) and to the heat exchanging device (7); a heating medium temperature detecting device (14), a heating medium flow rate detecting device (12) and a first heating medium flow control valve (13), which are provided on the heating medium supply piping (8) at respective locations between an outlet of the heating system (6) and an inlet of the heat exchanging device (7); and a control device (50) capable of calculating a value of supply thermal energy from results of detections by the heating medium temperature detecting device (14) and the heating medium flow rate detecting device (12) and controlling an operation of the heating medium flow control valve (13) based on the value of supply thermal energy thus calculated.
