A Novel Polygeneration System Based on a Solar-Assisted Desiccant Cooling System for Residential Buildings: An Energy and Environmental Analysis

This work aims to design and dynamically simulate a polygeneration system that integrates solar-assisted desiccant cooling for residential applications as an alternative vapor compression systems. The overall plant layout supplies electricity, space heating cooling, domestic hot water, freshwater single-family townhouse located in the city of Almería Spain. leading technologies used are photovoltaic/thermal collectors, reverse osmosis, air conditioning. model was developed accurately simulated TRNSYS environment 1-year simulation with 5-min time step. Design optimization carried out investigate system’s best configuration. optimal structure showed satisfactory total annual energy efficiency solar collectors about 0.35 0.47 Coverage 104.1%, 87.01%, 97.98%, 96.05 %, 100 respectively. Furthermore, significant ratios primary saving, 98.62%, CO2 97.17%, were achieved. users’ thermal comfort level over entire year. Finally, comparison coastal site performed extend applicability.
