HEAT MEDIUM SUPPLY FACILITY, COMPOSITE SOLAR HEAT ELECTRICITY GENERATION FACILITY, AND METHOD OF CONTROLLING THE FACILITIES

摘要

A heat medium supply device (4) where, even if a heat medium has a successive temperature variation, a heat exchanger is prevented from being adversely thermally affected by the variation. The heat medium supply device (4) has a heating facility (6) for heating the liquid heat medium by sunlight; the heat exchanger (7) for heating supplied water by the heat medium supplied from the heating facility (6); heat medium supply piping (8) for circulating the heat medium in the heating facility (6) and the heat exchanger (7); a heat medium temperature detection device (14), a heat medium flow rate detection device (12), and a first heat medium flow rate regulation valve (13) that are arranged in the heat medium supply piping (8), between the exit of the heating facility (6) and the entrance of the heat exchanger (7); and a control device (50) for calculating supply heat energy based on the result of detection by the heat medium temperature detection device (14) and the heat medium flow rate detection device (12) and capable of controlling operation of the heat medium flow rate regulation valve (13) based on the value of the supply heat energy.
