Abstract
This study discusses the importance of integrating renewable energy sources, particularly Solar Water Heating Systems (SWHSs) with Thermal Energy Storage (TES) technology, to address the growing energy consumption in residential buildings, aligning with the United Nations' Sustainable Development 2030 agenda. The combination of SWHSs and TES helps reduce building energy consumption by storing excess solar energy, which can be used for Domestic Hot Water (DHW) needs during peak periods and nighttime. The study proposes a dynamic model using TRNSYS software to simulate a SWHS over a 30-hour period in a residential apartment. Additionally, a novel MATLAB component simulates an encapsulated Phase Change Material (PCM) storage tank. The results show that the PCM storage tank efficiently stores around 18 MJ of thermal energy, reducing DHW energy requirements and sustaining desired water temperatures throughout the day, even with low solar radiation. This approach has significant potential to enhance energy conservation, thermal efficiency, and reduction of greenhouse gas emissions in residential hot water systems.
