Experiments on sodium carbonate solution for a solar pond at natural environment

Alternatif enerji kaynaklarından birisi olan güneş enerjisini, ekonomik yönden ucuz ve verimli bir şekilde toplama ve depolama sistemlerinden birisi de güneş havuzlarıdır. Yapılan bu çalışmada, güneş havuzunda, farklı konsantrasyonlara sahip Na2CO3 - H2O (sodyum karbonat-su) çözeltisinin doğal ortamda ısı depolama performansı deneysel olarak incelenmiştir. Deney tesisatı, Z.K.Ü. Karabük Teknik Eğitim Fakültesi'nde kurularak farklı yoğunluklara sahip 5 ayrı deney yapılıp güneş havuzundaki sıcaklık ve yoğunluk değişimleri grafikler halinde sunulmuştur. Yapılan deneylerde güneş havuzunun tabanı ile yüzey arasındaki sıcaklık farkı maksimum 21°C ve alt taşınım bölgesinde (ATB) en yüksek sıcaklık 49°C olarak elde edilmiştir.

Sodalı suyun bir güneş havuzunda doğal ortamda deneysel incelenmesi

In this study, varying concentrations of sodium carbonate solution in the solar pond in terms of heat storage performance has been examined. Five conditions with different density levels have been carried out and the changes in the temperature and density have been presented graphically within the solar pond. The hourly variation of solar radiation, ambient temperature and wind velocity were also recorded during the outdoor measurements. The experiments show that the maximum temperature difference between the bottom and top level of solar pond is 21°C and the highest temperature in Lower Convective Zone (LCZ) has been measured as 49°C. Experimental apparatus has been located at Karabük Technical Education Faculty of Zonguldak Karaelmas University, Turkey.
