Abstract

This research is aimed to study the storage tank stratification design parameters effects on the efficiency of the large solar hot water system. Computer simulation with detailed CFD simulation for the storage tank, coupled with TRNSYS program simulation for the entire solar hot water system, is performed to study the system performance for various thermal-stratification-baffles design of the storage tank. The study is made for three representative cities of Taiwan by input their typical-meteorological-year (TMY) data. The results indicate the performance of a large solar hot water system can be significantly improved with proper designed thermal stratification baffles in the storage tank.
