PURPOSE:To enable to control a heat accumulating temperature and a heat emitting temperature by a method wherein a constituents such as NaCH3 COO, CO(NH2)2, H2O or the like is employed as the heat accumulating material and the composition rate of ingredients thereof is changed. CONSTITUTION:The three-component system of NaCH3COO, CO(NH2)2, H2O, having NaCH3COO and CO(NH2)2 as the both ends constituents and containing CO(NH2)2 within 50% or less (excluding 0%) may be controlled in the heat accumulating temperature and the heat emitting temperature thereof by changing the composition rate of ingredients, further, is possessing the latent heat of 30cal/g or more. |
