초록
화산지형인 제주도의 지열에너지를 사용하기 위하여 지하공기를 측정하였을 때 지중 온도는 15∼18℃이며, 상대습도는 70~80%로 타 지역에 비하여 매우 높은 경향을 나타내고 있다. 본 연구는 제습기능 및 난방기능을 구비한 다단 제습·가열 열펌프 시스템의 개발에 관한 연구로써, 개발된 열펌프의 성능실험을 수행한 결과 흡입공기의 상태가 최저 15℃, 60%인 경우 총제습량이 1.797(kg/h)로 나타났으며, 최고 20℃, 80%인 경우 총제습량이 45% 증가한 3.269(kg/h)로 증가하여 충분한 제습이 이루어짐을 알 수있다. 또한, 난방능력은 흡입온도 17℃ 상대습도 70% 일 때 1.91로 가장 높은 효율을 얻을 수 있다.
Abstract
In this research, results of measuring temperature and relative humidity of underground-air-heat inJeju showed 15~18℃ and 70~80% each which are somewhat high compare to other regions. So the Multi-effectdehumidifying and heating Heat Pump system which has merged functions of dehumidification and heatingis made to solve this problem mentioned previously. When the suction air was 15℃ with 60% humidity,the outcome was 1.70 on COPh and 1.797(kg/h) on total amount of dehumidification, and also showed 1.87COPh with 1.87 total amount of dehumidification under the condition of 20℃ and 80% humidity of suctionair. Furthermore, COPh showed increased number which is 1.87 and also total amount of dehumidification increasedwhich was 3.269(kg/h). The highest COP can be achieved at 17℃ and 70% relative humiditycondition.
