고효율 PVT 모듈 개발을 위한 열교환기 형상별 성능 분석

PVT system consisting of PV panel and thermal collector is a hybrid system that converts solar energy into electric and thermal energy. Therefore, it has a lot of advantages in terms of installation area and economy. However, PVT systems have been difficult to raise market competitiveness than conventional energy sources due to high generation costs. In order to promote widespread supply of PVT systems, it is essential to improve the thermal efficiency, which occupies a large portion of the overall efficiency. In this study, the heat exchange performance according to shape of heat exchanger was predicted for the development of high efficient PVT module. As a result, the thermal efficiency for the parallel type was 92.91% and for the serial type was 69.21%. In other words, it was clear from the results that the parallel type was more effective than the serial type in terms of heat transfer from the bottom of PVT panel.
