Abstract

يهدف هذا البحث وضع طريقة سريعة وسهلة تعتمد أسلوب المصفوفات في حساب وتحليل الإكسرجي الضائع في كل عنصر من عناصر الدورات التبريدية أو الحرارية، وتحديد العناصر ذات الهدر الأكبر. تتألف عناصر هذه المصفوفات من الطاقات الداخلة والخارجة من كل عنصر من عناصر الدورة. تم وضع مخطط عام لحساب الإكسرجي الضائع باستخدام الخوارزميات بالاعتماد على معطيات المصفوفات، وتم التحقق من صحة هذه الطريقة من خلال مثال تطبيقي على دورة تبريدية بسيطة وتأثير تغيير بارامترات الدورة على الإكسرجي الضائع في العناصر. يبين البحث أن طريقة المصفوفات في حساب الإكسرجي الضائع هي طريقة فعالة وخصوصاً عند دراسة الدورات التبريدية والحرارية المؤلفة من عدد كبير من العناصر.

The main objectives of this research is to put together a general method in calculating exergy losses in each component in either heat or refrigeration cycles. The exergy will specify the worst component in the cycle. Based on flow chart that we have obtained from these matrices, we have been able to obtain the exergy losses. We have verified the flow chart by using a simplified refrigeration cycle and showed the effect of different parameters on exergy in each component. This method mentioned above is effective especially when we analyze the exergy losses in refrigeration and heating cycles with many components.
