Abstract AR
اختبار عملي تم إجراءه على ثلاثة أنابيب شعرية مختلفة الأقطار و الأطوال في منظومة تثليج باستخدام موائع التثليج R-12، R-134a.
الاختبار هو دراسة تأثير معدل التدفق و سرعة مروحة المبخر على المنظومة.
النتائج بينت بوضوح أن نوع المائع المستخدم و معدل التدفق يؤثران على تغير درجات الحرارة على طول الأنبوب.
بينما سرعة مروحة المبخر لها تأثير قليل.
الاختبار العملي بين كذلك تغير درجات الحرارة على طول الأنابيب الشعرية متشابهة بالنسبة للمائعين و لكن بعد متر واحد من طول الأنبوب الشعري فإن التغير لمائع R-134a أسرع من R 12.
Abstract EN
Experimental work has been performed on three capillary tubes of different lengths and diameters using R-12 and R-134a.
The test also studies the effect of discharge and speed of evaporator fan.
The results clearly showed that refrigerant type and discharge significantly influence the temperature drop across the capillary tube.
While the speed of evaporator fan has small effect.
Experimental results showed that the temperature gradient for the two refrigerants are the same, but after approximately one meter the temperature gradient of R-134a is steeper than R-12.
