Bu çalışmada, dizel motor atık ısısı geri kazanımlı organik Rankine çevriminin (ORÇ) termodinamik analizi, farklı çalışma sıvıları için yapılmıştır. Çevrimde çalışma akışkanı olarak R123, R245fa, R600a, R236ea ve R134a kullanılmıştır. Dizel motorun egzozundaki ısı kaynağının sıcaklığı 80-180 oC arasında seçilmiştir. Analiz için gerekli olan termodinamik değerler ve hesaplamalar Mühendislik Denklem Çözücü (EES) programı ile hesaplanmıştır. Bu çalışma akışkanları için, çevrim performans değerleri farklı çalışma koşulları altında incelenmiştir. Organik Rankine çevriminde analizi yapılan tüm çalışma koşulları için en yüksek verimlilik değerleri, R123 çalışma sıvısının kullanıldığı koşullarda % 23 olarak elde edilmiştir. Ayrıca, aynı çalışma koşulları için türbin gücü 7,2 kW olarak belirlenmiştir.

In this study, thermodynamic analysis of the
organic Rankine cycle (ORC) using a diesel engine waste heat recovery was
performed for different working fluids. R123, R245fa, R600a, R236ea and R134a are
used as working fluid in the cycle. For temperature of the heat source in the
exhaust of the diesel engine 80-180 oC was chosen. The required
thermodynamic values and calculations for the analysis were calculated by the Engineering Equation Solver (EES) program. For these working fluids, the
performance values of the cycle were studied under different operating
conditions. The highest efficiency values were obtained for all operating
conditions analyzed in the organic Rankine cycle using R123 working fluid as
%23. In addition, the turbine power is determined as 7.2 kW for the same
operating conditions.
