<P>PROBLEM TO BE SOLVED: To provide a latent heat accumulation composition and a heat exchange type heat accumulator capable of making a tank and the accumulator, compact in size capable of regulating easily a heat accumulating capacity, and capable of increasing a unit heat accumulation amount. <P>SOLUTION: This latent heat accumulation composition is a composition comprising a sodium acetate hydrate of repeating heat sink/radiation within a range of 83 kcal/l of a required heat quantity at 57°C in the generation of entropy. This heat exchange type heat accumulator is one with sealed with a water flow pipe 2 having aluminum heat transfer blades (fins) 3 in a heat accumulation container 4 and the latent heat accumulation composition, and heat pumped up by a heat pump using inexpensive night electric power is accumulated through the water flow pipe 2 to be used for heating, air conditioning and hot-water supply. <P>COPYRIGHT: (C)2007,JPO&INPIT |
