Abstract AR
تم إجراء مقارنة عملية بين مائعي التثليج R134a و R409a في دورة تثليج انضغاطية منزلية لدراسة مدى تأثر كفاءة الدورة عند درجات حرارة خارجية مختلفة و أخذا بنظر الاعتبار تأثير التسخين و التبريد الموضعي كلا على حدة، أظهرت النتائج أن المائع R409a يعطي معامل أداء أعلى و معدل استهلاك قدرة اقل من المائع R134a .كذلك لوحظ بان التسخين الموضعي يؤثر بشكل اكبر عند ارتفاع درجة حرارة المحيط للمائع R409a أكثر منه للمائعR134a ، أما اثر التبريد الموضعي للمكثف فقد اظهر تحسنا" في معامل أداء الدورة و استهلاك اقل للقدرة عند درجات الحرارة الأقل .
Abstract EN
An experimental comparison have been conducted between R134a and R409a working in a domestic refrigeration cycle experimentally, the results showed that R409a have better C.O.P.
and less power consumption for various ambient temperatures and degrees of superheating and sub-cooling.
Also, the superheating affected the cycle performance as ambient temperature increases especially for R409a, while the condenser sub-cooling causes the cycle performance improvement at lower ambient temperature
