采用10w级填料床反应器对氧化镁/水化学热泵进行了热性能试验研究。在圆柱形反应器中填充了一种具有高重复性操作耐久性的新型反应物。在405kpa的反应压力下，研究了氧化镁的水化反应。在热放大模式下，通过水化作用测量了100-240℃左右的产热。氢氧化镁脱水能够储存热电联产系统的余热和多余的夜间电力。热泵的蓄热密度与传统的显热蓄水系统的蓄热密度具有足够的竞争力。热泵有望应用于热电联产系统的负荷平衡，通过在低热需求时化学储存余热，并在高峰需求时提供热量。
A magnesium oxide/water chemical heat pump using a 10-W class packed bed reactor was examined experimentally to evaluate the thermal performance of the heat pump. A developed reactant having high durability for repetitive operation was packed in the cylindrical reactor. The magnesium oxide hydration was studied under reaction pressures up to 405 kPa, which were higher than one of previous work. Heat generation at around 100–240°C was measured by the hydration under the heat amplification mode operation. The magnesium hydroxide dehydration was capable to store the surplus exhaust heat from a cogeneration system and surplus night-time electricity. The heat storage density of the heat pump was sufficiently competitive with that of a conventional sensible heat water storage system. The heat pump was expected to be applicable for load leveling in a cogeneration system by chemically storing surplus heat during low heat demand and supplying heat during peak demand.
