چکیده
Three combined power and refrigeration system are introduced to compare and analyze for a defined demand and same fuel consumption based on thermodynamic parameters in a ۲۴ hours period. Gas turbine and/or steam turbine are used for power generation and also ejector refrigeration cycle is used to produce cooling. These three systems are named as GER, SER and GSER. The results of three systems are compared and it’s shown that SER has so much lower cogeneration efficiency than two other systems. GSER produces ۲۸۴ MWhr per year more power than GER with the same fuel consumption that can easily cover the additional capital cost of the system. Moreover, exergy efficiency of GSER is ۱۲% higher than GER and its cogeneration efficiency is ۸% higher than GER too. So, between these three systems we would recommend GSER because of better performance like higher exergy and energy efficiency and also better conformity with our demandکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
