Yeni Bir Güç/Soğutma Çevriminin Enerji ve Ekserji Analizi: Kalina Çevrimi ve Ejectörlü Soğutma Çevrimi

Bu çalışmada yeni bir bileşik güç/soğutma çevriminin termodinamik analizi sunulmuştur. Bileşik çevrim iki yeni çevrimin birleşiminden oluşmuştur: güç Kalina çevriminde (KNC), soğutma ise ejektörlü soğutma çevriminde (ERC) üretilmektedir. Sistem enerji ve ekserji verimlerini yükseltmek için bileşik çevrim tasarımında ısı geri kazanımı prosesine yer verilmiştir: KNC tarafından salınan ısı ERC tarafından alınmakta ve soğutma üretiminde kullanılmaktadır. KNC çalışma parametrelerinden türbin güç üretim kapasitesine direkt etkisi olan parametrelerin değişiminin (çevrim akışkanının türbin girişindeki sıcaklık ve basıncı), bileşik çevrim enerji ve ekserji verimi ve ayrıca, üretilen güç ve soğutmanın enerji ve ekserji karşılıklarına olan etkileri incelenmiştir. Elde edilen sonuçların detaylı incelemesi de çalışmada sunulmuştur. Enerji ve ekserji veriminin baskın şekilde bileşik çevrimde üretilen güç tarafından belirlendiği tespit edilmiştir. Diğer bir deyişle, bileşik çevrimin enerji ve ekserji verimini yükseltmek için KNC çevriminde güç üretim kapasitesini direkt etkileyen faktörler öncelikli olarak incelenmelidir.

Energy and Exergy Analysis of an Innovative Power/Refrigeration Cycle: Kalina Cycle and Ejector Refrigeration Cycle

This study presents a thermodynamic analysis of a new combined power/refrigeration combined cycle. The combined cycle is comprised of two innovative cycles: Kalina cycle (KNC) and ejector refrigeration cycle (ERC) for power and refrigeration production, respectively. Recovery of heat process is involved in the design of the cycle to rise the energetic and exergetic efficiencies: emitted heat by the KNC is absorbed by the ERC in order to generate cooling. Effects of variation in KNC operational conditions which have direct effects on turbine power production capacity (temperature and pressure of the working fluid flow at the turbine inlet) on performance evaluation parameters of the system (energy efficiency, exergy efficiency, energetic and exergetic content of produced refrigeration and net power) are investigated. A detailed discussion of the results is also reported. Energetic and exergetic efficiency results are substantially dominated by generated power, i.e., KNC parameters which impose direct effect on turbine power production performance is of superior importance to rise the energy and exergy efficiencies.

Keywords:

Ejector refrigeration, Kalina cycle, Combined cycle, Energy efficiency, Exergy efficiency.,
