Abstract
The object of the present study is the integration of a solar cooling and heating system of a residential building (4-flour) located in Blida region in Algeria. The system consists of a set of solar collectors that supply energy to a balloon through an external heat exchanger. The solar and auxiliary tanks are connected by a heat exchanger immersed in the bottom of the auxiliary tank. In the distribution loop, a recirculation can make possible to obtain the domestic hot water set point temperature. A cold production system is directly connected to the solar tank and a regulation system ensures the control of the installation. We have used the TRANSOL software under TRANSYS to calculate the heating and cooling load. Several parameters are then introduced to size and evaluate the performance of our installation. The results obtained are satisfactory .
Highlights
About 40% of the national energy consumption in Algeria is due to the residential sector
This solar fraction is very important which, unlike heating, essentially results from the advantage of having needs and contributions in phase, which makes this application very interesting
We have studied a multifunctional solar system (ECS, heating and cooling) using the TRANSOL software in dynamic mode to see the thermal behavior of the studied block after the integration of solar systems
Summary
About 40% of the national energy consumption in Algeria is due to the residential sector. Hernandez et al, [4] studied the performance of a solar heating and cooling system integrated to an office building located in southern Italy. This analysis, which was done under TRNSYS simulation, gave very promising results. Bahria et al [10] They performed a parametric optimization using dynamic simulation of a solar thermal system for the production of hot water, space heating and cooling. Presentation of the building The studied building is part of a national pilot project aimed to build 600 housing with high-energy performance (see figure 2, [14]). The sizing allows using a solar system and minimizes the contribution the extra-system
