Abstract    This analysis principally focuses on the implementation of Radial basis function (RBF) and back propagation (BPA) algorithms for training artificial neural network (ANN) to get the optimum mixture of Hydro fluorocarbon (HFC) and organic compound (Hydrocarbons) for obtaining higher coefficient of Performances (COPs). The thermodynamical properties of mixed refrigerants are observed using REFPROP 9 software system that contains details of refrigerants. Totally different mixtures of the refrigerants along with their COP are obtained by the REFPROP 9. This task consumes time in getting the right combination of refrigerants as lot of menu choices have to be compelled to be chosen within the REFPROP 9. In order to form the method of checking out the correct mixed refrigerants with minimum manual intervention, RBF is trained and tested with the different patterns of mixed refrigerants. The RBF / BPA mixed refrigerant analysis software has been developed by using MATLAB 11a.

چکیده    این تحلیل اساساً بر کاربرد الگوریتم‌های تابع پایه‌ی شعاعی (RBF) و پس انتشار خطا (BPA) برای آموزش شبکه عصبی مصنوعی (ANN) برای به دست آوردن مخلوط بهینه از هیدرو فلوروکربن (HFC) و مواد آلی (هیدروکربن ها) برای به دست آوردن بالاتر متمرکز است. خواص ترمودینامیکی از مبرد مخلوط REFPROP 9 با استفاده از سیستم نرم افزاری حاوی جزئیات مبرد مشاهده شده است. مخلوط‌های کاملاً متفاوت از مبرد همراه با ضریب‌های کارایی‌شان بر اساس 9 REFPROP به دست آمده است. تعیین ترکیب مناسبی از مبرد زمان زیادی لازم دارد زیرا باید گزینه‌های بسیاری از درون REFPROP 9 انتخاب شود. به منظور پیدا کردن یک روش چک کردن مخلوط صحیح مبرد با حداقل مداخله‌ی دستی، RBF آموزش دیده و با الگوهای مختلف مبرد مخلوط مورد آزمایش قرار می‌گیرد. نرم افزار تجزیه و تحلیل مخلوط مبرد RBF / BPA با استفاده از MATLAB 11A توسعه یافته است.
