Einsatz thermischer Solaranlagen in betrieblichen Prozessen und Anwendungsbereichen mit besonderem Bezug zum Bundesland Oberösterreich

The application of solar thermal systems in the industrial sector, one of the most important economic fields in Upper Austria, is affected by many different parameters. These physical-technical characteristics (solar radiation, scale of temperature or energetic efficiency), economic factors (development of costs, competitiveness, etc.) and political-social changes in research and funding or simply the significance of ustainability affect each other again. Thus, the importance and the dimension of this technology in the rare applications (like solar air conditioning, solar process heating and cooling), are influenced by numerous protagonists. There are many tools to determine low-temperature energy demand in companies which can be used for evaluation of alternatives. Several projects show that solar thermal systems in this area are feasible and make sense. Furthermore they can activate positive economic effects. Although the cost to avoid greenhouse gases are comparatively high, growing private finance structures and research and aid programmes support the industrial use of solar thermal systems.
