In this experimental study, the air cooling radial shape heat exchanger which influences on the COP and the cooling capacity by heat and mass transfer rate in the adsorbent bed was designed and applied to test its performance for adsorption heat pump(AHP). Zeolite-water was used for the adsorbent-adsorbat pair. As a result, the cooling COP and a cycle period of this adsorption heat pump are 0.28 and 2 hours, respectively, on the condition of none heat recovery from the adsorption reactor(absorber). The other results and recommendations are mainly related to improving the heat and mass transfer inside the absorber to reduce a cycle period.

This study is on the evaluation of KIER Zero Energy Solar House(ZeSH). This ZeSH was designed and constructed for the goal of 70% self sufficiency only thermal loads. Various innovative technologies for reducing thermal load such as super insulation, high performance window, passive solar systems, ventilation heat recovery system , etc are applied in this ZeSH. In this study, the performance of the active solar heating system with geothermal heat pump as an auxiliary energy system and the energy self sufficiency rate are especially analyzed by experiment. Indoor setting temperature of ZeSH is 20℃ throughout the experimental period. As a result, the performance of active solar system is 35 to 40% depending on the various ambient condition and the solar fraction for heating season is about 74%.
