摘要：

A chemical heat pump with cold heat storage using sodium carbonate decahydrate and oxalic acid dihydrate is proposed, aiming at a load - levelling system after theoretical comparison of heat pump systems from the viewpoint of COP and storage volume. Then dehydration of sodium carbonate decahydrate was investigated. Solid reactant powders were encapsulated with polyvinylbutyral resin to prevent pulverization and the thickness of capsule wall was so adjusted that particles with a radius of 2 mm were dehydrated in ten hours. The reaction took place smoothly in cyclic operation.
