In the refrigeration and air conditioning fields, the needs of energy conservation and renewable energy spread have become stronger recently. In this study, we aim at the development of heat driven type Metal Hydride (abbr. MH) refrigeration system which is able to be driven by the low temperature exhausted or solar heat of under 100℃. It is necessary to improve the heat transfer and activation characteristics of MH, and to decrease the price of it, for the practical use of heat drive type MH refrigerator. In the present study, to enhance the low thermal conductivity of MH particle bed, heat pipes (HPs) are inserted into the heat source side MH (simply MH1) particle one. And, by this method, we also aim at the acquirement of temperature uniformity of MH1 particle bed. The cooling performance of heat driven type MH refrigeration system is estimated by experiment and calculation. As a result, this study was previously reported 1.61 times the refrigerating capacity (0.038W/kgMH) gained and show the advantage of heat pipe.
