Abstract

In this study, subcooling and superheating heat exchangers of vapor compressed refrigeration system were investigated in terms of thermoeconomics for two different refrigerants and optimum working conditions were determined. Coefficient of structural bonds was used as thermoeconomic optimization method. Analyses were carried out for refrigerant R22 and alternative of it, refrigerant R407c. As a result, optimum areas of subcooling and superheating heat exchangers are determined in relation to economics and working performance. For a refrigeration system design, decrease of heat exchanger area, affects the system cost as a decrease. However, decrease of heat exchanger area, causes a decrease in efficiency value of system. In the present study, optimum conditions for the optimum heat exchanger area and optimum system efficiency are determined.

Özet

Bu çalışmada, teorik bir buhar sıkıştırmalı soğutma sisteminin aşırı kızdırma ve aşırı soğutma ısı değiştiricilerinin, farklı iki soğutucu akışkan için ısıl ekonomik yönden analizi yapılmış ve sistemin en iyi çalışma şartları belirlenmiştir. Isıl ekonomik en iyileme metodu olarak, yapısal bağ katsayıları metodu kullanılmıştır. Analizler, R22 soğutucu akışkanı ve buna alternatif olarak R407c soğutucu akışkanı için yapılmıştır. Sonuç olarak, aşırı kızdırma ve aşırı soğutma ısı değiştiricilerinin ekonomik ve çalışma performansı açısından en iyi alanları tespit edilmiştir. Bir soğutma sistemi tasarımında, ısı değiştiricisi alanının azalması, sistem maliyetini düşürür. Fakat ısı değiştiricisi alanının düşürülmesi sistem verimini de düşürmektedir. Yapılan çalışmada, ısı değiştiricisi alanının, ve sistem veriminin en iyi olduğu şartlar belirlenmiştir.
