Solar Heating and Energy Performance of Buildings Using a Solar Chimney Coupled with PCM and Concrete Thermal Reservoirs

Summary

Transient simulations of a residential solar chimney in Tehran compare phase change materials of differing melting points with concrete thermal storage for heating and ventilation. Melting point strongly shapes performance: a mid-range PCM kept air moving almost around the clock and cut October heating demand by up to about 75%, against 50% for concrete, while a lower-melting PCM worked better in colder months.
