유출지하수 열원 지열히트펌프시스템의 냉방성능

다국어 초록 (Multilingual Abstract)

Effluent ground water overflow in deep and broad ground space building. Temperature of effluent ground water is in 12{sim}20?C annually and the quality of that water is as good as living water. Therefore if the flow rate of effluent ground water is sufficient as source of heat pump, that is good heat source and heat sink of heat pump. Effuent ground water contain the thermal energy of surrounding ground. So this is a new application of ground source heat pump. In this study open type and c lose type heat pump system using effluent ground water was installed and tested for it church building with large and deep ground space. The effluent flow rate of this building is 800{sim}1000 ton/day. The heat pump capacity is 5RT each. The heat pump cooling COP is 4.9{sim}5.2 for the open type and 4.9{sim}5.7 for close type system. The system cooling COP is 3.2{sim}4.5 for open type and 3.8{sim}4.2for close type system. This performance is up to that of BHE type ground source heat pump.
