PURPOSE:To improve the heat accumulating efficiency of a solar-heat utilizing apparatus in which a part of a closed circuit for recirculating a heating medium via a solar heat collector is located within a heat accumulating tank, by constructing the heat accumulating tank such that it is formed therein with an inner and an outer containers filled respectively with latent-heat accumulating mediums. CONSTITUTION:In a solar-heat utilizing apparatus shown in the drawing, heat is accumulated in a latent heat accumulating medium 8 by passing a heating medium circulated in a solar heat collector 3 by a pump 4 to a heat exchanger 2 in the latent accumulating tank 1. Here, the tank 1 is designed to have an inner and an outer enclosed containers 15, 17 made of polyethylene resin or the like, and latent-heat accumulating mediums 16, 18 are respectively filled in the inner container 15 and a hollow space between the inner and the outer containers 15 and 17. Further, an heat-insulating material 22 such as foamed plastics is filled in a space between the outer container 17 and a casing 21 for protecting the container 17. Heat exchangers 11, 2 are inserted respectively into inserts 23, 24 which are inserted into connecting passages 19, 20, to such an extent that they are located within the inner container 15. The heat exchanger 11 is connected to a sensible-heat accumulating tank 9 filled with water 10 via a circuit including a pump 12. |
