This dissertation was written as a part of the MSc in Energy Systems at the International Hellenic University. The main purpose of this thesis is the background research and the development of a model for a hybrid installation using a PV/T air system with a desiccant cooling system in TRNSYS. An energy and an economic assessment were performed on the viability of the system under different assumptions. The building and the HVAC sys-tem was designed, simulated and optimized under certain assumptions. Additionally, a sen-sitivity analysis was performed with different parameters of the simulated system. The sys-tem was also compared to a simulated conventional one from energy and economic view. The results have showed that the PV/T-desiccant system covers the heating and cooling demand throughout a year for a typical office building for four different cities of different climatic zones in Greece. Moreover, part of the electricity consumption is generated by the photovoltaics. Finally, the energy and economic analysis have showed that the created sys-tem is feasible for all the studied cases and it is preferable to the conventional one. At this point, I would like to express my sincere thanks to the person who have help and supported me during the elaboration of the present dissertation, Dr George Giannakidis. Moreover, I would like to thank Dr George Martinopoulos who have assisted me with the installation of the TRNSYS. Finally, I should show gratitude to my family and friends for the continuous support during the drafting of this dissertation and also during all the years of my studies.
