사무소 건물에서 조명 열회수 시스템 운전 방법이 공조기 코일 부하에 미치는 영향에 관한 연구 ( A Study on the Effect of the Operation Method of the Lighting Heat Recovery System on Coil-load in AHU in Office Buildings )

In office buildings, internal heat gains are growing due to the development of Intelligent Buildings. Particulary, the lighting heat gain can accout for 25-50% of building electrical energy usage. Electrical energy to meet the cooling loads imposed by lighting can add another 10-20%. So, the lighting heat recovery system can save the energy use in buildings. In this study, lighting heat recovery methods and the potential of energy savings are discussed and simulated to determine the proper operation method.
