This paper represents a design and analysis of a solar domestic hot water and space heating system with thermal storage for single-family house. To meet the energy demand of residential sector like a house, one of the best options is solar water heating system that can be integrated with space heating (SH) and domestic hot water (DHW). This type of systems performance and efficiency relies on proper design method, the actual size of the components, characteristics, and the behaviour of selected heat transfer fluid and the accurate analysis with the appropriate software. In this paper, a complete solar thermal based heating system is introduced that meets the overall energy demand of a house. The designed collector area 18 m2, storage tank 31 m3 is chosen with the volume to area ratio 1.72. It is also noticeable that the percentage of solar coverage for space heating and hot water is 32 and 59 respectively with average collector efficiency 51 %. Moreover, the overall hot water and space heating coverage using the designed system are 100 % that makes the good agreement with the literature. Design, simulation results, and detailed analysis of this research are included in this paper. |
