TÜRKİYE KOŞULLARINA UYGUN TÜPLÜ-DÜZ YÜZEYLİ KAPALI SİSTEM TİP BİR GÜNEŞ ENERJİLİ SU KOLEKTÖRÜNÜN GELİŞTİRİLMESİ

Abstract

Making use of solar energy is one of the ways that hot water is obtained nowadays. Because of its position in the sun belt, Turkey is well-positioned to utilize this limitless energy. Research into producing novel and inventive designs for collectors in order to boost collector efficiency ought to proceed quickly because of global warming. In this experimental investigation; a tube-flat plate closed system type solar water collector that is constructed from 304 chromium material and appropriate for Turkey meteorological conditions has been designed and manufactured. This solar collector has also been tested according to EN (European Union Norms) 12975-2 (2003) for its thermal efficiency. This collector can be worked as a closed system with help of working fluid; it is never freeze during cold weathers; it can be used during all seasons and  can be directly connected to the  pressurized city water line system; it is not to give any negative effects on chemical compositions of the water; it is  not to be needed any maintenance during lifetime and  it have less price, more lifetime, high thermal efficiency, easier assembling and manufacturing when compared with aluminum and copper type collectors. As a result of the work, it was seen that the average end use thermal efficiency of this collector is 49.50%.
