The present invention relates to a device for supplying water to the (用水), such as heating and hot water through a heat exchanger to the solar heat collection.
One pairs of panels of the secondary characters give to the collector solar collector is installed in a longitudinal direction, each of which is equipped with a first pivot axis both panels; A heat exchanger including, and supplies the fluid outflow through the fluid outlet of the final-stage collector connected to the collector fluid outlet and the fluid inlet in series with each other and connected in series between the receiving group; The heat exchanger with a plurality of first isolated by partitioning one hot water tank and the second hot first accumulator and the second accumulator is connected in a parallel type (Type) to the inlet branch point and the outflow junction which a fluid is circulated is installed each internal section; It is branched at the branch point and each of the inlet connected to the first accumulator and the second accumulator, opened by the control unit - the first solenoid valve and the second solenoid valve is closed (Open-Close) control; Wherein the first hot water tank and the second hot first water each filled tank that heat through the first accumulator and the second accumulator with fluid flows along a closed control, the first solenoid valve and the second opening of the solenoid valves and a second water; The first water outlet provided in the hot water tank from the first outlet side so that water from the first water and a second water; That is configured, including as its characteristics.
