EXPERIMENTAL INVESTIGATION OF SOLAR POND PERFORMANCE IN KARABUK ENVIRONMENT

The solar energy, one of the alternative energy sources, can be economically and cheaply and efficiently collected with solar ponds. In this study, varying concentrations of sodium carbonate dilution in the solar pond in terms of heat storage performance has been examined. Experiment apparatus has been located Zonguldak Karaelmas University Karabük Technical Education Faculty. Five experiments with different density levels have been done and the changes in the temperature and density have been presented graphically within the solar pond. The experiments show that the temperature difference between the bottom and top level of solar pond is max. 21 °C and the highest temperature in lower convective zone (LCZ) has been measured as 49 °C.

KARABÜK ÞARTLARINDA GÜNEÞ HAVUZUNUN PERFORMANSININ DENEYSEL ÝNCELENMESÝ

Alternatif enerji kaynaklarýndan birisi olan güneþ enerjisini, ekonomik yönden ucuz ve yüksek verimli enerji olarak toplama ve depolama sistemlerinden birisi de güneþ havuzlarýdýr. Yapýlan bu çalýþmada, güneþ havuzunda, farklý konsantrasyonlara sahip Na2CO3 – H2O (sodyum karbonat-su) çözeltisinin doðal ortamda ýsý depolama performansý deneysel olarak incelenmiþtir. Deney tesisatý, Z.K.Ü Karabük Teknik Eðitim Fakültesi’nde kurularak farklý yoðunluklara sahip 5 ayrý deney yapýlýp güneþ havuzundaki sýcaklýk ve yoðunluk deðiþimleri grafikler halinde sunulmuþtur. Yapýlan deneylerde güneþ havuzunun tabaný ile yüzey arasýndaki sýcaklýk farký maksimum 21 °C ve alt taþýným bölgesinde (ATB) en yüksek sýcaklýk 49 °C elde edilmiþtir.
