Özet
Bu çalışmada, Mersin ili iklim koşullarında güneş enerjisinden faydalanılarak deniz suyunun damıtılması işlemi teorik olarak değerlendirilmiştir. Bu değerlendirme sera tipi ve yüksek sıcaklıklı aktif çalışan güneş enerjili damıtma sistemleri için yapılmıştır. Her iki sistem için de verim değerleri hesaplanmıştır. Güneş enerjili pasif bir damıtma sisteminden maksimum verim ile faydalanabilmek için, sisteme güneş kolektörü ilave edilmiştir ve aktif bir güneş enerjili damıtma sistemi elde edilmiştir. Her iki sistem için de sistem bileşenleri; sistemin üzerini örten saydam cam örtü, havuzdaki deniz suyu kütlesi ve havuzun yalıtım malzemesidir. Aktif güneş enerjili damıtma sisteminde bu bileşenlere bir de vakum tüplü güneş kolektörü eklenmiştir. Her bileşenin ısıl analizi yapılmıştır. Verim hesapları için ise iterasyon yapılmıştır. Havuzdaki suyun ve saydam cam örtünün sıcaklıkları arasındaki fark, verim üzerindeki etken parametredir. Mersin iline ait olan ve Mersin Meteoroloji İstasyonu Müdürlüğünden temin edilen, 1999 – 2009 yılları arasındaki aylık ortalama verilerin kullanıldığı damıtma sistemleri verim hesaplamalarında, yüksek sıcaklıklı aktif sisteme ait sonuçların genel olarak sera tipi sistemden yüksek olduğu görülmüştür. Söz konusu 10 yıl için, özellikle Temmuz ve Ağustos aylarının ortalama verilerinden elde edilen sonuçlar arasında önemli ölçüde farklılıklar vardır. Düşük maliyetli bir vakum tüplü güneş kolektörünün sisteme entegre edilmesi ile önemli derecede verim farklılıklarının oluştuğu görüldüğünden, böyle bir uygulamanın yüksek sıcaklıklı aktif güneş enerjili damıtma sistemi ile gerçekleştirilmesinin daha elverişli olacağı sonucuna ulaşılmıştır.
In this study, solar distillation processes was evaluated theoretically in Mersin climate conditions for active and pasif solar stills. The daily productivity, the yield was calculated for both of these systems. To be able to get more benefit from passive solar still, an evacuated tube collector was integrated to passive still and so an active solar still has been produced. The solar stills component for both systems are the glass cover over the still, the still that contains the seawater and the insulation material inside the still inner surfaces. An evacuated tube collector was added to components for the active solar stills. The thermal analysis was performed for all components for both of these solar stills. Iteration method was used to obtain the daily yields. The difference between the temperatures of water and glass covers is the main parameter to obtain the daily yields. The results of the active solar stills are higher than passive stills in terms of the daily yield that calculated from the monthly average climate data of Mersin between years of 1999 – 2009. These data were supplied from Mersin Meteorological Station. Between the mentioned years, especially for the months of July and August, there were obtained big differences between the yieldst of passive and active stills. With addition of an cost effective evacuated tube collector to passive solar still, an important difference was obtained; so, an active solar still is more effective to obtain fresh water from seawater by distillation process by using solar energy.
