Abstract

يهدف هذا البحث إلى دراسة تأثير التراصف الحراري في الخزان الحراري على الأداء الحراري لنظام تسخين الماء الشمسي وذلك باستخدام برنامج المحاكاة TRNSYS. فقد تم تحليل الأداء الحراري لنظام التسخين الشمسي باستخدام حمل الماء الساخن والشروط المناخية كمعطيات لبرنامج المحاكاة لدراسة تأثير عدد مداخل الماء الساخن إلى الخزان الحراري (عدد الطبقات الحرارية في الخزان الحراري) على مردود اللاقط الشمسي ونسبة التغطية الشمسية. لقد أظهر هذا البحث أنه يتم الحصول على أعظم قيمة لمردود اللاقط الشمسي ونسبة التغطية الشمسية عند استخدام ثلاثة مداخل إلى الخزان الحراري (n=3) ويكون مقدار التزايد في المردود 6[%]-2 بينما مقدار التزايد في نسبة التغطية الشمسية  4-8[%].

The objective of this investigation is to study the effect of thermal stratification on the thermal performance of water heating system using TRNSYS simulation program. Solar water heating system was analyzed using hot water loads and hourly weather data as data input to the simulation program to study the influence  of number of hot water inlets to storage tank (number of thermal nodes in storage tank) on solar collector efficiency and solar fraction. The investigation showed that the highest collector efficiency and the highest solar fraction occurred by using three inlets to storage tank (n=3), where the increase of collector efficiency is about 2-6[%] and the increase of solar fraction is about 4-8[%].
