Energetic Performance Analysis of a Solar Combisystem. Application to a Rural House in Chlef Region (Algeria)

During the last decade, housing construction has become a priority axis in the development policy in Chlef district (north-west of Algeria). However, the construction of these homes surely leads to a significant increase in energy consumption of this region. This makes the reduction of energy consumption in buildings is a major challenge. Space heating and cooling loads are the most post energy consumer. These loads can be reduced through many means; notable among them is the thermal insulation of the building envelope and use of solar energy.In this paper, the energetic performances of a solar combisystem providing both space heating and domestic hot water for a typical rural house located in Chlef district are analyzed. Two cases are investigated and their performances are compared. The first case considers the house in its current condition and the second case considers that the envelope house is well thermally insulated and single glazing windows are replaced by double glazing windows. Energy balances are established using Trnsys software.
