<P>PROBLEM TO BE SOLVED: To provide a pile type heat exchanging device filled with latent heat storage material for improving heat exchanging efficiency and heat storage efficiency, and to provide a heat storage system using the same in combination with a heat exchanger pipe for a solar collector for maintaining a good heat energy giving-receiving balance throughout the year. <P>SOLUTION: The pile type heat exchanging device 5 utilizes underground heat in the state that a heat exchanger pipe body 2 is arranged in a hollow portion of a pile 1 embedded in the ground of a predetermined depth for circulating and distributing heat medium and the latent heat storage material 3 filled in the hollow portion of the pile 1. The heat storage system uses the same in the state that heat medium circulating and distributing part of the solar collector 10 utilizing solar heat is inserted and embedded as a heat exchange portion 22 into the latent heat storage material 3 filled in the pile type heat exchanging device 5 and combined therewith to form an integrated heat storage region F including the pile type heat exchanging device 5 embedded in the ground and surrounding soil. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
