Investigation Of Performance Of An ORC System With Different Working Fluids And Turbine Isentropic Efficiencies
Öz
The Organic Rankine Cycle (ORC) is the thermodynamic cycle commonly used to convert low-grade heat sources into useful work. To maximize the efficiency of the ORC system, it is important to select a suitable working fluid and turbine. This study aims to investigate the effect of turbine isentropic efficiency and different coolants on the overall performance and efficiency of ORC. In this context, a thermodynamic analysis including various parametric studies has been carried out to compare the coolant performance under different operating conditions. In line with the findings, the parametric studies revealed that the highest efficiency was 13.79% when R123 was used at 85% turbine isentropic efficiency and the lowest efficiency was 8.42% when R365mcf was used at 60% turbine isentropic efficiency. However, the highest turbine power was calculated to be 5.506 kW at 85% turbine isentropic efficiency using R1233zd(E) fluid. In addition, the highest and lowest exergy dissipation is 4.065 kW at 60% turbine isentropic efficiency using R1233zd(E) fluid and 2.196 kW at 85% R123 fluid, respectively.

Organik Rankine Çevrimi (ORC), düşük dereceli ısı kaynaklarını faydalı işe dönüştürmek için yaygın olarak kullanılan termodinamik çevrimdir. ORC sisteminin verimliliğini en üst düzeye çıkarmak için uygun bir çalışma akışkanı ve türbinin seçimi önemlidir. Bu çalışmada, türbin izentropik verimliliğinin ve farklı soğutucu akışkanlarının ORC'nin genel performansı ve verimliliği üzerindeki etkisini araştırmayı amaçlanmaktadır. Bu kapsamda farklı çalışma koşulları altında soğutucu performansını karşılaştırmak için çeşitli parametrik çalışmalar içeren bir termodinamik analiz gerçekleştirilmiştir. Elde edilen bulgular doğrultusunda, yapılan parametrik çalışmalarda en yüksek verimin %13.79 ile R123 akışkanının %85 türbin izantropik veriminde kullanıldığı durumda, en düşük verim ise %8.42 ile %60 türbin izantropik veriminde R365mcf akışkanının kullanıldığı durumda gerçekleştiği ortaya koyulmuşutur. Bunula birlikte en yüksek türbin gücünün R1233zd(E) akışkanın kullanıldığı %85 türbin izantropik veriminin olduğu durumda 5.506 kW hesap edilmiştir. Ayrıca en yüksek ve en düşük ekserji yıkımı sırasıyla %60 türbin izantropik veriminde R1233zd(E) akışkanını kullanıldığı durumda 4.065kW, %85 R123 akışkanın kullanıldığı durumda 2.196 kW olduğu belirlenmiştir.
