摘要: Abstract This paper investigates the thermal performance of a forced circulation collective solar water heater (SWH) equipped with centralized storage tank, throughout hourly dynamic simulations. The main purpose this study is to identify parameters affecting overall efficiency process, because literature review focuses on individual SWHs, rather than hot systems that are extensively integrated in tertiary sector, such as hotels, hospitals, university residences, etc. Hence, being able suggest general recommendations would be helpful guide system designers. A typical residence located Fez city (Morocco) shelters 60 occupants was considered realistic case study, for which performances production were simulated. Several indicators defined and miscellaneous simulations carried out enhance process's efficiency. For instance, incident energy collector panel, supplementary consumptions different tank volumes load profiles, useful gain from collector's field fraction process. results showed Evacuated Tube Technology (ETC) suitable application, process remains higher ETC, opposed use Flat Plate Collectors (FPC). Moreover, increasing volume enhances annual Last but not least, maximal averaged achieved by ETC technology (78%). However, it equal 68% (FPC) while maintaining 3000 l capacity.
