Simulation and Evaluation of Solar Water Heating Systems Availability in Mosques Sector in the City of Tripoli- Libya

Abstract

Mosques are classifid as one of the most attractive places for the Libyan people during prayer times, where electrical power is consumed extensively and converted into many energy types. Hot water is required for ablution during the cold season, which occupies 5 months per year, approximately, where electrical power is utilized to provide hot water demand. In this paper, the
possibility of installing solar water heaters in ten mosques in the city of Tripoli is studied, according to an agreement between the General Authority of Awqaf and Islamic Affirs and CSERS. Threfore, a detailed study was performed for site shading probability during the year using Climate Consultant 6.0 softare, and Sketchup Make 2017. Furthermore, the solar water heating system was designed by (T*SOL Pro 5.5) design and simulation softare. Th results have illustrated that employing thermosyphon systems could fail to fulfi water heating load in the studied mosques, due to the presence of the surrounding buildings shade during winter and the high water heating load of such crowded mosques. However, the present study suggests the use of central pumped solar water
heating systems (forced circulation), which are able to provide high capacities with low electrical consumption. Moreover, the pumped systems are compatible with the conventional fuel powered systems.
