In this study, thermal performance of plain finned-tube
evaporators in household refrigerators are investigated numerically and
experimentally. The design parameters affecting on the cooling capacity are
determined as air flowrate, evaporator temperature, tube alignment, number of tubes
and number of fins. In the initial stage, the effects of those parameters on
the cooling capacities are simulated by CoilDesigner software. The number of
experiments that are necessary to obtain correlations is determined by Minitab
software. The experiments are carried out in a no-frost household refrigerator
in the off-mode. At the end of each experiment, air side heat transfer
coefficients are calculated to generate a Nusselt (Nu) correlation as a
function of the mentioned design parameters.  The generated correlation of the cooling
capacity can predict 95% of the experimental results within a confidence range
of 15%.  The correlation of the cooling
capacity is converted to the Nusselt number correlation which is found to be
consistent with available data in literature. The experiments reveal that the
cooling capacity is dominantly affected by the evaporator temperature followed
by air flow rate, tube alignment, number of tubes and the number of fins.

Bu çalışmada, düz kanatlı
borulu buharlaştırıcıların ev tipi buzdolaplarındaki ısıl performansı sayısal
ve deneysel olarak incelenmiştir. Soğutma kapasitesini etkileyen tasarım
parametreleri, hava debisi, buharlaştırıcı sıcaklığı, boru düzeni, boru sayısı
ve kanat sayısı olarak belirlenmiştir. İlk aşamada, bu parametrelerin soğutma
kapasiteleri üzerindeki etkileri CoilDesigner yazılımı ile modellenmiştir.
Isıl inceleme için gerekli olan deneylerin sayısı Minitab yazılımı tarafından
simülasyon sonuçlarına göre belirlenmiştir. Deneyler ev tipi bir buzdolabında
kapalı soğutma çevrimi olmaksızın yapılmıştır. Her deneyin sonunda hava
tarafı ısı transfer katsayıları, söz konusu tasarım parametrelerinin bir
fonksiyonu olarak ve Nusselt (Nu) korelasyonu oluşturmak için hesaplanır.
Soğutma kapasitesi için oluşturulan korelasyon, deneysel sonuçların % 95'ini
% 15'lik bir güven aralığında tahmin etmektedir ve literatürdeki mevcut
verilerle tutarlı bulunmuştur. Deneyler, soğutma kapasitesinin baskın olarak
buharlaştırıcı sıcaklığından ve ardından hava kütlesel debisinden, boru
düzeninden ve kanat sayısından etkilendiğini ortaya koymuştur.
