Theoretical Analysis of Combined Solar System Based on Dual Purpose Solar Collector
Abstract
In the present work, the detailed mathematical model of a dual purpose solar collector (DPSC) has been developed and experimentally validated. To demonstrate the application of the DPSC, three buildings with different energy consumption were chosen as case studies and four solar collector systems were compared among one another. The solar yield of the described systems was determined by detailed thermal simulations in TRNSYS using TRNSYS Building environment (TRNBuild) and a detailed theoretical model of DPSC. The results of the modeling indicate that, in the case of combining domestic hot water preparation system and recirculating air heating system based on DPSC, it is possible to achieve a higher solar energy yield compared to a conventional solar domestic hot water preparation system.
