Numerical analysis of an integrated solar cooling and heating system in individual house in different Algerian climates

Abstract

There is a growing concern about energy use in Algeria. As fast as, building programs developed and living conditions improved, the building sector makes big focus as a major energy end-user. Main energy needs in buildings are due to heating and/or cooling, depending on local climatic conditions and type of building. In this paper, the primary aim is to analyze two aspects–heating load, and cooling load of an individual house energy consumption in the major climatic zones in Algeria. The individual house uses heating and cooling solar system. The system performance is simulated using TRNsys program. This solar heating and cooling system incorporates between 89m2and 170 m2of flat plate double glazed solar collectors, which provide solar energy contribution during both the heating and cooling seasons; between 13.28kW and 25.11 kW single effect, water–lithium bromide (H2O/LiBr) absorption chiller. This system is the smallest solar heating and cooling system in the world.
