Özet (Çeviri)

The environmental approach for energy production trends is tending to separate in two different point of view. One is produced the required energy by using renewable sources such as the sun. The other is that recovering what is already there. The Transpired Solar Collector (TSC) has been used successfully worldwide over the past three decades and has shown to achieve an economic payback of 2 to 10 years. This is a result of a combination of high thermal efficiency and the low cost of the solar collector. To meet energy-saving trends, legislation for fresh air supply in buildings, heat recovery systems has been used to transfer the heat of the exhaust air into the fresh airstream. In this research, the optimization procedure is carried out for both the transpired solar collector and the rotary heat recovery unit when a reference building with the same needs is situated in locations with different climates (Hamburg, Budapest, Malaga, Helsinki, Bilbao, and Erzurum). The aim of this study compares two different approaches for the same building with ventilation needs while demonstrating their performance in different available application sizes and optimize them economically. Later, results are evaluated for combining both systems in one involves optimized TSC size with rotary HRV. Interestingly, conclusions of comparisons showed that rotary HRV has always better results in economic and thermal performance for six different European cities. Even though there are some cities with cost per energy in MWh results are getting closer with optimized TSC size applications such as Helsinki. Another fact is that optimized TSC combined with optimized rotary HRV always tends to be the most expensive solution from a sustainable environment and an economic point of view. Results aim to help fellow scholars, as well as industrial engineers in the dimensioning and decision-making process of the transpired solar collector and rotary heat recovery unit.
