Açık dikey tip soğutucu teşhir dolabın faz değiştiren malzeme kullanılarak enerji verimliliğinin sayısal ve deneysel olarak incelenmesi

Bu çalışmada kabin boyutları 2500 mm uzunlukta, 2059 mm yükseklik, 920 mm derinlikte olan açık dikey tip soğutucu teşhir dolabının (ADSTD) enerji verimliliğini arttırmak üzere faz değiştiren malzeme (FDM) uygulaması yapılmıştır. TS EN ISO 23953-2 standartlarına göre test edilen FDM uygulaması yapılan dolabın, hava giriş ve çıkış sıcaklıkları, kompresör defrost periyodu ve devreye girme (on), devreden çıkma (off) durumları, paket sıcaklıkları ve enerji tüketimi incelenmiştir. Test verileri üç boyutlu hesaplamalı akışkanlar dinamiği yöntemi kullanılarak doğrulanmıştır. Bu sonuçlara göre, belirtilen kabin boyutlarında soğutucu teşhir dolaplarına uygulanan FDM’nin, geleneksel dolaba göre enerji verimliliğini % 5,10 arttırdığı görülmüştür.

Anahtar Kelimeler:

‘’Açık dikey tip soğutucu teşhir dolapları’’, ‘’faz değiştiren malemeler’’, ‘’ISO 23953-1-2 test standartları’’, ‘’üç boyutlu hesaplamalı akışkanlar dinamiği’’
