Study on Rock Bed Thermal Storage System for Space Heating Applications Using TRNSYS

Solar energy has outstanding potential as a renewable source of energy. Presented work deals with building ofsuch heat storage system which can store heat radiated from sun during the day and provide space heating at night bygradually discharging it for space heating application. TRNSYS is a robust numerical tool that was used to model asolar-powered heating system with a rock bed storage unit. This heating system is used to heat a ۴۰ m۲ dwelling housein Kerman. The obtained results show that this strategy helps store energy during daytime hours and has a uniformtemperature distribution during cold winter days.
