Chemical heat-pump is able to upgrade exhaust heat to useful heat at energy conservation system. Especially, hydration chemical heat-pump is able to operate on higher temperature than another heat pump. In this study, CaBr2 and H2O were selected as combination of absorbent and working medium and operating conditions were shown in the combination. Also, output characteristic experimentally were evaluated on some operating conditions and continuous cycle operation. As results of experiments, heat storage temperature needs 160 degrees C at condenser temperature 20 degrees C and heat release temperature gets 220 degrees C at evaporator temperature 80 degrees C. Therefore, 60degrees C rise in temperature and higher heat release temperature than 200 degrees C were shown in the chemical heat pump of the combination. And, 1000th maximum output and absorbent ratio was reduced by 32.1% and 9.2% compared to 10th that. After continuous
operation, the packing state of absorbent was changed and absorbents were away from heat-transfer surface.
