چکیده
معماران گذشته در اکثر نقاط کشورمان آب­انبارها را برای نگهداری و خنک نگه­داشتن آب، جهت استفاده مردم در بیشتر نقاط اقلیمی کشورمان مخصوصا (گرم خشک، سرد) بنا می­کردند. برای انجام این تحقیق دو نمونه گنبد آب­انبار با طاق و قوس مختلف از شهر یزد و دو نمونه از شهر قزوین انتخاب گردید، سپس گنبدها بر اساس نقشه­های واقعی در نرم افزار رویت 2017 مدلسازی شد. تا میزان دریافت تابش خورشید بر سطوح گنبدها در گرم­ترین روز سال در ساعات 14، 16، 18 برای اقلیم گرم خشک و در سردترین روز سال در ساعات 13، 14، 16 برای اقلیم سرد قزوین با استفاده از پلاگین­های انرژی پلاس هانی بی و لیدی باگ بدست آید.نتایج نشان دادند میزان دریافت تابش در سطوح گنبدها متفاوت است. گنبدهای خیز بلند در ساعت 14 تقریبا 78% و گنبدهای خیز کم 93%، در ساعت 16 گنبدهای خیز بلند 71% و گنبدهای خیز کم 81%، در ساعت 18 بعد از ظهر که زاویه تابش خورشید تقریبا 80 درجه تغییر می­کند، گنبدهای خیز بلند 67% و گنبد خیز کم 64% از سطوح­شان در معرش تابش خورشید قرار می­دهند. گنبدهای خیز بلند مناسب برای اقلیم گرم خشک و گنبدهای خیز کم مناسب برای آب انبارهای اقلیم سرد می­باشند

چکیده English

In the past, architects in many parts of Iran had built traditional public buildings to create a community convenience and comfort. Ab Anbars are good example of this facility structures which they were suppose to collect water in rainy condition and keep it cool for use in dry condition of year espacialy in hot and arid climate. To study amount of radiation and heat absorption 2 Domes of Ab Anbar in Yazd (hot and arid climate) and 2 Domes of Ab Anbar in Qazvin (cold climate) were selected. In order to simulate the domes, they were first modeled in Revit software 2017, and then models were transferred to Rhino 5 software, using the honeybee & lady bug, and with the Energy plus Engine analysis of the received solar radiation and shading were done. In the analyzes, uniformity of the dimensions of the Ab Anbars domes were used, so that the optimum dome can be obtained in terms of receiving solar radiation and absorbing heat in the shadowed area. To equalize the domes, the absorption of the sun's radiation of each dome is divided by the amount of shadowing of the same dome.Radiation absorption in hottest day of the year in hat and arid climate and coldest day of year in cold climate were calculated using Energy Plus software Honeybee & ladybug Plugins. Result shows that amount of radiation is dependent to form of domes. During study day (14,16 and 18 o’clock ) 78, 71 and 64 percent of high rise Domes is facing radiation while 93,81 and 64 percent of low rise domes is facing radiation. From this results it can be concluded that high rise domes have better function in hot and arid climate and low rise domes have better function in cold climate in relation to radiation absorption.
