چکیده

باتوجه به اهمیت انرژی و محدود بودن منابع موجود، برنامه‌ریزی مناسب برای گسترش استفاده از سیستم­های پربازده امری اجتناب‌ناپذیر است. سیستم­هایCCHP  ازجمله سیستم­هایی است که به‌منظور بالا بردن راندمان تولید انرژی و کاهش هزینه­های ­مربوط به‌کار می­رود. از زمان ظهور این سیستم­ها تا به امروز، روش­های مختلفی به‌منظور تعیین ظرفیت تجهیزات و بهینه­سازی آنها ارائه شده‌است. در پژوهش حاضر، پس‌از معرفی اجمالی روش­های تعیین ظرفیت، شامل روش ماکزیمم بار (MLM)، روش ماکزیمم مستطیل (گرمایی MRM,h و الکتریکیMRM,e ) و روش یکنواخت سود سالیانه نسبی (REUAB) به ارائۀ یک روش جدید به‌منظور بهینه­سازی سیستم CCHP برای یک مجتمع مسکونی با محرک اولیه موتور گازسوز پرداخته می­شود. در این روش سه معیار انرژی، اقتصادی و زیست‌محیطی به‌همراه ملاحظات مربوط به روش‌های گذشته بسط داده می­شود و در انتها با اعمال شرایط واقعی برای محرک اولیه نتایج بهینه‌سازی مورد ارزیابی قرار خواهد گرفت.

چکیده [English]

The importance of energy and shortage of its sources have necessitated appropriate planning for developing systems with high efficiency. Combined cooling, heating and power generation systems CCHP, are systems that used for increasing the efficiency of generated energy, while decreasing costs. Since the invention off CCHP systems, different methods have been provided for determination capacity of equipment and their optimization. In this research, at first these systems summary  are presented and then three main methods namely maximum load method (MLM), maximum rectangle method (heating MRM,h and electric MRM,e ) and relative equivalent uniform annual benefit method(REUAB), for determination of capacity of prime mover have been introduced. Then for a residential convened that its prime mover is gas engine, with consideration three mentioned methods and a new proposed method, for optimization the CCHP will be explained. Finally, the results of the optimization with applying real conditions for prime mover are investigated.
