Abstract

In This paper, a theoretical study of a hybrid renewable energy system that uses geothermal and solar heat sources for water heating, space heating, and space cooling in a residential building in Algeria is presented. The system consists of a geothermal heat pump for heating and cooling, solar collectors for hot water, heat exchanger, turbo compressor and incidental facilities. Based on energy balance, the heat transfer modes of all main components in this system cascade into an order four matrix are calculated by Gauss-Saidel method. The results show state, the total efficiency, electrical and thermal efficiency of this system increase with increasing of the water mass flow rate, and decreases with the increasing of the exchanger cannel depth.
