PURPOSE:To enhance the utilization degree of a heat accumulating agent, by providing many heat accumulating elements, which are formed by packing a small capacity of the heat accumulating agent by a thin film, in the heat carrier part in a heat accumulating container. CONSTITUTION:The hot air which is heated by a solar heat collector is introduced into the container 1 from a heat carrier inlet part 5 of the heat accumulating container 1. Said hot air passes through the gap in each heat accumulating body 10 which is wound in a roll shape, and contacted with each heat accumulating element 12. At this time, the heat is exchanged between the hot air and the heat accumulating element 12. The heat in the hot air is taken by each heat accumulating element 12 and accumulated in the element 12. Since the heat carrier, out of which the heat is taken, and whose temperature is decreased, is exhausted from a heat carrier exhausting part 6 at the lower part. Therefore the utilization degree of the heat accumulating agent is enhanced. |
