Bu çalışmanın amacı, güç, soğutma ve sıcak su üretmek için parabolik oluklu kollektörlü (PTSC) entegre organik Rankine çevrimi (ORC) ve ejektörlü soğutma çevriminin enerjik ve ekserjetik analizini incelemektir. Trijenerasyon sisteminin performans değerlendirmesini yapmak için EES yazılım programı kullanılmaktadır. Hesaplamalarda termodinamiğin birinci ve ikinci yasaları kullanılmıştır. Termodinamik analiz sonuçlarına göre trijenerasyon sisteminin enerjik ve ekserjetik verimi sırasıyla %26.67 ve %14.21 olarak hesaplanmıştır. Aynı zamanda, güneş ışınımının, türbin giriş sıcaklığının ve jeneratör sıcaklığının kombine çevrim performansı üzerindeki etkisini incelemek için parametrik çalışmalar yapılmıştır. Trijenerasyon sisteminin parametrik çalışmaları incelendiğinde, trijenerasyon sisteminin enerjik- ekserjetik verimi ve toplam ekserji yıkımı, güneş ışınımı ve türbin giriş sıcaklığının artmasıyla artarken, jeneratör sıcaklığının artmasıyla toplam ekserjetik verim azalmaktadır. Ayrıca en yüksek tersinmezlik oranı 150 kW ile PTSC'de iken, en düşük tersinmezlik oranı ise ejektör soğutma sisteminin pompasında 0,02 kW olarak hesaplanmıştır.

Thermodynamic Analysis of Ammonia Based Direct Steam Generation Trigeneration System

The goal of this study is to examine the energetic and exergetic analysis of parabolic trough collector (PTSC) based integrated organic Rankine cycle (ORC) and ejector refrigeration cycle for generate power, refrigeration, and hot water. EES software program is used to carry out the performance evaluation of the trigeneration system. The first and second laws of thermodynamics are used in the calculations. According to the results of the thermodynamic analysis, the energetic and exergetic efficiency of the trigeneration system are computed as 26.67% and 14.21%, respectively. At the same time, parametric studies have been performed to examine the effect of solar radiation, temperature of turbine inlet, and generator temperature on combined cycle performance. When the parametric studies of the trigeneration system are examined, the energetic and exergetic efficiency of the trigeneration system and the total exergy destruction rise with the increase of solar irradiation and turbine inlet temperature, while the total exergetic efficiency reduces as the generator temperature rises. Moreover, the highest rate of irreversibility has the PTSC with 150 kW, while the lowest amount of irreversibility is calculated as 0.02 kW in pump of the ejector cooling system.
