Simulation and Optimization of Solar Domestic Hot Water Systems

Energy-efficient building is the only solution to reduce energy costs and greenhouse gas emissions. A solar combi-system is a solar installation that provides both domestic hot water and heating. In this work, the authors evaluated the energy needs of such a system in the case of an F3 type house on a site in Meknes. The technical regulatory document is used to determine the energy demand for heating and to verify the conformity of the buildings to the thermal regulations. The domestic hot water demand is evaluated according to the analytical method. A thermal simulation of the production of domestic hot water under TRNSYS 16 confirms the results obtained by the analytical method.
