하천수를 이용하는 열펌프시스템의 냉방성능평가

It is required that various kinds of unused energy from urban area and industrial sectors be recovered and re-utilized from the viewpoints of energy saving and environmental conservation. Since most of this heat demand is low temperature below 60℃, the utilization of "unused energy" is surely one of very effective measures to both environmental preservation and energy conservation. "Unused energy" is implicated as "temperature difference energy" available from water-heat sources for heat pump including river, sewage arid sea. The present study has been conducted to develop a heat pump system using fiver as a heat sink.
