배기열 회수용 종이 열교환기의 성능에 영향을 미치는 인자에 관한 연구 = A Study on the Factors Affecting the Performance of Paper Heat Exchanger for Exhaust Heat Recovery

다국어 초록 (Multilingual Abstract)

In order to control indoor air quality and save energy, it is needed to install a suitable ventilation system equipped with heat exchanger for heat recovery. The purpose of this research is to find the factors affecting the performance of paper heat exchanger for exhaust heat recovery, which can be applied directly to the conventional ventilation unit, air- purifier, and air-conditioning system. In this study, thermal performance and pressure loss of the paper heat exchanger are measured and compared at various operating conditions. The effectiveness of sensible, latent and total heat at the face velocity of 0.75m/s are 77%, 47% and 57% in the cooling condition and 77%, 59% and 69% in the heating condition, respectively. The effectiveness for sensible heat is only affected by velocity. On the other hand, the effectiveness for latent heat is affected by temperature and relative humidity.
