| Abstract |
The chemical heat pump based on the Dehydration/Hydration process with a MgO/H2O system has been researched. The reactor bed could be expected to store the heat around 200～370℃ by the dehydration reaction and to release the heat around 100～160℃ by the hydration reaction under the heat amplification mode operation. The heat output rate of the heat pump system was evaluated using the experimentally determined parameters. The results show that 6～50W/kg of heat output and 0.5～0.8 of heat recovery ratio are attainable. The heat pump will be applicable for a load leveling in a co-generation system by chemical storage of surplus heat at low heat demand and by supplying heat in the peak load period. |
