Creating a TRNSYS Model of a Spiral Flow Flat Plate Solar Water Heater (SFSWH) and Comparingit to a Parallel Flow Flat Plate Collector: A Recent Study

A specific SFSWH system for domestic hot water is proposed in Kovilpatti, Tamilnadu, 9°10'N 77°52'E. The results were clarified using parallel flow solar water heaters as a contrast after this SFSWH device was successfully simulated in TRNSYS Software. To begin, a complete model of a spiral flow flat plate collector is created in TRNSYS software, accounting for heat transfer, outlet temperature, and performance. This model is then theoretically compared to a parallel flow flat plate collector using the TRNSYS simulation programme. With the aid of NASA surface meteorology and solar energy year readings, as well as ISRO's solar calculator application, the SFSWH device performs a role relative to Kovilpatti, Tamilnadu, India. An experimental setup was done at Kovilpatti to prove the accuracy of the TRNSYS model of the SFSWH, and necessary results were obtained under Kovilpatti weather conditions. The validation of this SFSWH TRNSYS model simulation programme is completed by comparing the expected software results with the original results. The SFSWH TRNSYS model result shows that the SFSWH performs better than a traditional parallel flow water heater. As a consequence, the TRNSYS model is dependable, and it alternates the experimentation.
