Performance analysis of solar heat generation system for multi-purpose applications

This study presents a thermal performance simulation of solar central heat generation system for multipurpose applications. A theoretical model is developed using TRNSYS software and an experimental test rig is planning to be installed at the Center for Solar Energy Research and Studies in Tajoura, Libya. The system consists 80 evacuated tubes collectors solar field arranged in parallel and series and attached to two hot water storage tanks of 1200 liters. In the first phase, the system will be used for space heating of the administration building and the production of fresh water using MSF desalination unit of 5 m
₃
/day. The results of the simulation show that over 90% of the required energy of space heating can be provided by the solar system and about 60% for the desalination unit.
