Sažetak
Very important to know at a positive-energy building in the design phase is what portion of the whole energy usage will be collected from renewable resources. In this case, at RATI Factory building in Komlo, Hungary, numerical fluid simulations (CFD) have been made to determine the heat transfer coefficients (α) for photovoltaic modules in this specific installation, and to investigate the passive ventillation, assisted by so-called Venturi-Plates. The efficiency of the natural ventilation depends on the geometrical properties (openings, Venturi-tower height, Venturi-plate design, etc.), and the photovoltaic efficiency is also influenced by air flow, since it is cooling the modules. Heat transfer at photovoltaic modules can be described among other methods, with heat resistance network. The inside of material behaviour depends on physical properties, but the heat transfer at the boundary is described by α, which hangs big rate on the air flow around the modules. These CFD simulations were validated by real wind tunnel tests, and on these pre-tests is based the ventilation control and the coming measurements in the already existing building.
