Ateş Tuğlası Parçalarının Güneş Enerjili Hava Isıtıcılarında Isıl Enerji Depolama Malzemesi Olarak Kullanılmasının Isıl Verimliliğine Etkisi

Öz

Tarım ürünlerinin kurutulması ve mekân ısıtması gibi uygulamalarda ihtiyaç duyulan sıcak hava, hava ısıtıcılı güneş kollektörleri ile elde edilebilmektedir. Suya göre, havanın ısı transfer katsayısı daha düşüktür. Bu sebeple hava ısıtıcılı güneş kollektörlerinde yüzey alanı artırılmış depolama malzemeleri kullanılarak hem daha yüksek sıcaklıklarda hava elde edebilmekte hem de enerjinin depolanması sağlanarak kollektörün toplam verimi artırılabilmektedir. Ateş tuğlaları gibi yüksek sıcaklıklara dayanıklı malzemeler, düşük ısı iletkenliğine ve yüksek ısı kapasitelerine sahiptirler. Bu çalışmada, depolama ve ısıl enerjinin tekrar kullanımında bir tür refrakter olan ateş tuğlasına ait parçalar kollektör içerisine yerleştirilerek, kollektörün verimi üzerine etkileri incelenmiştir. Hava ısıtıcılı güneş kollektörüne farklı miktarlarda ateş tuğlası parçaları uygulanmış, ışınım altında ve soğutma sırasında ısıl verimleri karşılaştırılmıştır.

The Effect of Using the Fire-brick Fragments as a Thermal Energy Storage Material on Thermal Efficiency of Solar Air Heater

Öz

The hot air needed in applications such as drying agricultural products and space heating can be obtained with air-heated solar collectors. Air has a lower heat transfer coefficient than water. Using storage materials with increased surface area in air-heated solar collectors provides both obtaining higher temperatures output air and increased the total efficiency of the collector by storing energy. Refractory materials such as fire bricks have low thermal conductivity and high thermal capacities. In this study, the effects of refractory fire-brick fragments which are a kind of refractory in storage and reuse of thermal energy on collector efficiency were investigated. Fire brick fragments of different densities were applied into the solar air heater collector and their thermal efficiencies were compared during under radiation and cooling.
