Abstract

A series of field tests on hybrid desiccant cooling systems were conducted in July-August, 2013. The temperature and humidity of the supply and return air, power, and heat consumption were monitored and transferred in real time through the Internet. The performance parameters of the cooling system, namely, cooling capacity and COP (coefficient of performance), were evaluated from the measured data and their variations under outdoor conditions was analyzed. It was found that with increase in the outdoor temperature, the total energy decreases and cooling capacity increases whereas the latter decreases with increase in the outdoor humidity. The COP was also found to increase with the increase in outdoor temperature.

하절기 에너지 이용의 합리화를 위해서는 소형 열병합 발전의 설비이용률을 높일 수 있는 지역냉방의 보급이 확대되어야 한다. 지역냉방에는 흡수식 냉동기와 제습냉방기 있는데 상대적으로 낮은 열원을 사용할 수 있어 지역난방에 연계할 수 있는 제습냉방이 공동주택용으로 각광을 받고 있다. 본 논문에서는 고체제습제를 이용며 현열로터 대신에 히트펌프를 사용한 하이브리드 제습냉방 시스템의 주거환경에서의 성능 특성을 분석하였다. 실내공급공기, 실내리턴공기, 실외흡입공기, 재생열량, 소비전력을 측정하여 인터넷을 이용한 모니터링을 통하여 데이터를 분석하였다. 전체에너지는 외기온도가 증가할수록 감소하였고 냉방능력은 외기온도가 증가할수록 증가하고, 외기습도가 감소할수록 증가하는 경향을 보였다. 성능계수는 냉방능력과 유사한 경향을 보이는 것으로 분석되었다.
