摘要：
In this experimental study, chemical heat pump (CHP) characteristics for heat storage and heat release in repetitive operation were examined. The input/output heat of the CHP in repetitive operation was found to be controlled by the special pressure adjustment procedure such as instant vacuuming or additional vacuuming for pressure-temperature control of the CHP reactor. In the case of the CaO/H2O/Ca(OH)(2) hydration/dehydration system, the CHP is found to produce controlled-temperature hot/cold heat in a repetitive operation using chemically stored energy during both heat-storing and heat-releasing steps.
