Abstract:

In a step towards overcoming the increased energy demand of residential buildings in Libya, This study presents the design of solar water heating system for an apartment in Tripoli operating by thermo siphon, to provide the households by the required hot water for the domestic purpose. In this study *f*-Chart method is used for this purpose, which is used by most researchers and professionals in the sector, due to its simplicity and ability to estimate the solar fraction (*f*), which is expressed as a percentage; is the contribution by the solar system to the average daily water heating requirements. Once *f* is calculated, the amount of solar energy that displaces conventional energy for water heating can be determined. Solar fraction depends on several factors that include, among others, hot water consumption profile, system location, orientation and tilt angle of collector, and tank size. All data for this section are based on monthly daily averages of incident solar radiation, temperature, and atmospheric conditions. Finally, this research shows the benefits that can be realized from this application, which includes the monthly and yearly amount of electrical savings and the quantities of harmful emission gases which can be avoided. Furthermore, some recommendations that support and spread the use of the solar water heating systems in Libya.
