Abstract
In this study. CaBr_2 liquid-solid hydration is applied for heat storage without heat exchanger. Two experiments of the reaction were conducted. The amount of generated vapor in equilibrium state was evaluated. The vapor was generated instantly in this reaction. The maximum vapor of 6.5 mol/L-solution could be generated. and its COP was 0.12. The regeneration of CaBr_2・2H_2O completed after 320 seconds at the temperature of 190℃ and the salt layer thickness of 1 mm. In other cases. the reaction times were all longer than that in the above condition, due to detachment of the layer from the heating surface and high thermal resistance.
