Abstract

إن الغاية من هذا البحث هو استخدام دارة التبريد الإمتزازية كتقنية واعدة في مجال التبريد المقاد بالطاقات النظيفة بهدف توفير الطاقة وذلك من خلال وضع المعادلات الناظمة للتوازن الحراري والكتلي لدارة تبريد إمتزازية ثنائية المرحلة وإجراء الحسابات ضمن الشروط التصميمية في سوريا

تمت برمجة كافة المعادلات ضمن برنامج حاسوبي ودراسة أثر تغير بعض البارامترات المؤثرة على الدارة وتوصلنا إلى أن الدارة المدروسة يمكن أن تحقق درجات حرارة منخفضة حتى   وقادرة على العمل حتى درجات حرارة خارجية  ولكن معامل الأداء للدارة ينخفض مع انخفاض درجة الحرارة الداخلية المطلوبة ومع ارتفاع درجات الحرارة الخارجية كما أن زيادة الحمل المطلوب تحقيقه يؤدي إلى تناقص متسارع لمعامل الأداء.

 

The objective of this paper is to investigate the adsorption refrigeration cycle as a promising refrigeration technique that works using clean resources. The major aim is achieving energy-efficient system compared to the traditional system. This is approached by applying the equations of heat and mass equilibrium for a two-stage adsorption refrigeration cycle, taking into consideration the climate conditions in Syria.

We solved the equations numerically to study the effects of different parameters changes. It is proved that the studied cycle can reach a relatively low temperature as -32 [℃]. Moreover, it can be operated in ambient temperature as high as 53 [℃]. In contrast, the coefficient of performance decreases with the decrease of the internal temperature and the increase of the ambient temperature. Additionally, the study shows that increase of the cooling load causes an accelerated reduction in the coefficient of performance.
