Abstract

Termodinamiğin Birinci Kanunu ile yapılan hesaplamalarda her bir ünitede oluşan sıcaklık farkından ve basınç kayıpları nedeniyle oluşan tersinmezliklerin sistem performansı üzerindeki etkileri belirlenememektedir. Bu nedenle Termodinamiğin ikinci kanunu ve ileri ekserji analizi metodu kullanılarak, seçilen termal sistemde her bir ünitede oluşan ekserji tahribatının büyüklükleri ve ekserji tahribatı tipleri hesaplanmalıdır. Bu çalışmada, buhar sıkıştırmalı soğutma sistemi ile çalışan bir test ünitesinin performansı ekserji ve ileri ekserji analiz metodu ile incelenmiştir. İleri ekserji analizi sonucunda buhar sıkıştırmalı soğutma test ünitesindeki her bir bileşenin günümüz de ulaşılabilen en son teknolojiyi içeren ürünlerin kullanıldığını göstermektedir. Yapılan çalışmada evaparatörün diğer bileşenler arasında en yüksek termal performans ile çalıştığı bulunmuştur.

APPLICATION OF ADVANCED EXERGY METHOD TO THE VAPOUR COMPRESSION COOLING TEST UNIT

Abstract

In the calculations made using the first law analysis method of Thermodynamics, the effects of irreversibility caused by temperature difference, pressure losses and heat transfer in each unit can not be determined on thermal system performance. Therefore, by using the second law of thermodynamics and advanced exergy analysis method, the magnitude of the exergy destructions and the types of exergy destructions occuring in each unit in the selected thermal system can be used in the performance evaluation stage of the system. In this study, the performanse of the test unit which is operated by a vapor compression cooling system was investigated by means of the exergy and advanced exergy analysis methods. Advanced exergy analysis is showed that each component of vapour compression refrigeration test uses the latest technology available today. In the study, it was found that the evaporator operates with the highest thermal performanca among the other components.
