Abstract AR
هذه الدراسة قدمت الشحنة المثالیة التي حسنت بالإستھلاك الكهربائي في الضاغط و معامل الأداء لغاز R432A بدون تغییر الضاغط.
أظهرت نتائج الاختبار بأن أفضل شحنة ھي 750 g لغاز R432A الذي أعطى المعامل الأعلى للأداء و أقل استهلاك لطاقة.
عندما يشحن النظام في 750 غرام, فإن كمية الشحنة تقل بنسبة 42.3% بالمقارنة بالغاز الأصلي.
الزيادة في معامل الأداء هي 9.85%, 8.93% و نسبة استهلاك طاقة أقل 7.53%, 7.31% و 7.34 عند درجات حرارة بيئية 30, 34 و 38 درجة مئوية على التوالي لغاز R432A بالمقارنة مع R22.
Abstract EN
The study presents optimized R432A charge by the index of power consumption of compressor and COP without changing the compressor.
Test results showed that the best charge is 750 g for R432A which gave the highest coefficient of performance and less energy consumption.
When charging the system with 750 grams, the amount of charge rate down to 42.3 % compared with the original gas.
The percentage increase in coefficient of performance are 9.85 %, 8.39 %, and 8.93 % and the proportion of low energy consuming are 7.53 %, 7.31 %, and 7.34 % at ambient temperatures of 30 °C,34 °C and 38 °C respectively for R432A compared to R22.
Increasing ambient temperature lead to increase in the power consumed and decrease coefficient of performance.
