Abstract

In this study, the thermodynamic analysis of the solar energy assisted geothermal Organic Rankine Cycle (ORC) system was made under the atmospheric conditions of Konya. R141b was considered as the work fluid in the system. The geothermal energy source is determined as 50°C. The system was supported by solar energy in daytime conditions. The energy production, first law and exergy efficiency of the system for unit geothermal fluid flow rate (mj=1kg/sec) were determined for hourly, monthly and annual periods. Exergy destruction values and percentages of the system elements were determined for the annual period. Annual electricity production was obtained 3711 kWh for unit geothermal fluid flow rate. The contribution of solar energy and geothermal energy to annual electricity generation has been determined as 5.3% and 94.7%, respectively. The first law efficiency of the system has been determined as 4.3% for daily, monthly and annual periods. The annual exergy efficiency of the system has been determined as 6.1%. The annual exergy destruction rates of the system were obtained as 60.2% in solar collectors, 16.3% in the condenser, 13.1% in the evaporator, 11.3% in the turbine, 0.6% in the heat exchanger and 0.3% in the cycle pump.

Özet

Bu çalışmada Konya ili atmosferik şartlarında güneş enerjisi destekli jeotermal kaynaklı Organik Rankine Çevrimi (ORÇ) sisteminin termodinamik analizi yapılmıştır. Sistemde iş akışkanı olarak R141b seçilmiştir. Jeotermal enerji kaynağı 50°C olarak belirlenmiştir. Sistem gündüz şartlarında güneş enerjisi ile desteklenmektedir. Birim jeotermal akışkan debisi (mj=1kg/sn) için sistemin elektrik üretimi, enerji ve ekserji verimleri saatlik, aylık ve yıllık peryotlar için belirlenmiştir. Sistem elemanlarının ekserji yıkım değerleri ve yüzdeleri yıllık verilere göre belirlenmiştir. Sistemden birim jeotermal akışkan debisi için yıllık elektrik üretimi 3711 kWh olarak hesaplanmıştır. Güneş enerjisi ve jeotermal enerjinin yıllık elektrik üretimine katkısı sırasıyla %5,3 ve %94,7 olarak belirlenmiştir. Sistemin enerji verimi saatlik, aylık ve yıllık peryotlar için %4,3 olarak belirlenmiştir. Sistemin yıllık ekserji verimi %6,1 olarak belirlenmiştir. Sistemin yıllık ekserji yıkım oranları güneş kolektörlerinde %60,2, kondenserde %16,3 evaporatörde %13,1, türbinde %11,3, ısı değiştiricide %0,6 ve çevrim pompasında %0,3 olarak elde edilmiştir.
