Bu çalışmada iç ortam şartlarında
güneş simülatöründe vakum tüplü U-borulu bir güneş kollektörü test edilerek
verim eğrisi oluşturuldu. Farklı akışkan debilerinde güneş kollektörünün basınç
düşümü belirlendi. Simülatörden güneş kollektörü üzerine gelen ışınlar halojen
lambalarla sağlanmakta olup, ışınımlar kollektör üzerine güneş ışınları gibi
birbirine paralel olarak gelmediğinden verim hesabında, absorber izdüşüm
alanının kullanılmasının yanıltıcı olacağı görüldü. Daha gerçekçi bir yaklaşım
olarak, ışınımların geldiği açısal absorber alanının hesaplanması ile ilgili
bir yöntem geliştirildi. Kollektör absorber izdüşüm alanına bağlı kollektör
verimi %116 ile %80 arasında değişirken, açısal absorber alanına bağlı
kollektör veriminin %56 ile %38 arasında değiştiği görüldü. Deneysel çalışmadan
elde edilen bu sonuçlar, güneş simülatöründe vakum tüplü güneş kollektörü
testlerinde verim hesabında kullanılacak alanın belirlenmesinin önemini ortaya
çıkardı. Ayrıca kollektördeki akışkan debisinin kollektör verimine ve basınç
düşümüne etkisi de incelendi. Kollektördeki akışkan debisi arttıkça basınç
düşümünün de arttığı, göreceli olarak akışkan debisi ile verimde de bir artış
gözlendi.

Analysis of the Test Results on the Solar Simulator of the U-Pipe Evacuated Tube Solar Collector

In this study, a U-pipe evacuated
tube solar collector was tested in a solar simulator under indoor conditions
and an efficiency curve was formed. The pressure drop of the solar collector
was determined for different mass flow rates. Beams that come from the
simulator to the solar collector are provided with halogen lamps. Since beams
from the lamps do not come parallel to the collector like solar beams, it would
be misleading to use the absorber projection area in the calculation of
efficiency. As a more realistic approach, a method that calculates the angular
absorber area of beams was developed. While collector efficiency that depends
on the collector absorber projection area varies between 116% and 80%,
collector efficiency that depends on the field of the angular absorber has
changed between 56% and 38%. These results obtained from the experimental study
reveal the importance of determining the collector’s area to be used in the
solar simulator for the efficiency calculation of evacuated tube solar
collector tests. The effect of fluid flow on collector efficiency and pressure
drop is also investigated. As the fluid flow in the collector increases, the
pressure drop also increases and a relatively increase in the efficiency is
observed.
