PURPOSE:To improve water returning operation by a method wherein return water from a heat collector and/or a load is introduced into a small tank defined in a heat accumulating water tank by dividing it with specific partitioning plates. CONSTITUTION:The layers of cool water and warm water, formed in the small tank 9 based on the temperature difference therebetween are moved in parallel and in the same level to a main tank 10 by a method wherein substantially upright partitioning plates 8, dividing the heat accumulating tank 2 into the small tanks 9 and the main tank 10, are provided with multiple communicating holes 11 from the bottom part thereof to the positions near the level of water therein. The heat accumulating water tank 2 is forming a primary water circulating circuit, consisting of return water and feed water pipelines 4, 5, between a solar heat collector 1, and a secondary water circulating circuit, consisting of the return water and feed water pipelines 6, 7, between the load 3. Further, a discharging pipe 12 for the return water pipe 6 is dipped into the substantially central part of the small tank 9 while the feed water pipe 7 is connected to a box type opening 14 attached to the wall surface of the main tank 10 opposing to the partitioning plate 8. According to this method, high temperature water may be taken out of the feed water pipe 7 sequentially even if any of low, high or middle temperature water is returned from the return water pipe 6. |
