چکیده مقاله :
زمینه و هدف: رفتار حرارتی ساختمان های زیر زمین، نسبت به ساختمان های روی زمین متفاوت است. نزدیکی دمای درون زمین به متوسط دمای سالانه محیط، باعث کاهش تبادل حرارت این بناها، نسبت به ساختمان های روی زمین می شود. کاهش مصرف انرژی، انتشار گازهای گلخانه ای را کاهش می دهد. هدف این پژوهش امکان سنجی استفاده از انرژی زمین گرمایی در ساختمان به منظور کاهش انتشار آلاینده دی اکسید کربن در شهر همدان با شرایط اقلیمی سرد در سال 1398 می باشد. روش بررسی: شبیه سازی با استفاده از نسخه 0-1-8 نرم افزار انرژی پلاس انجام شد. مدل مورد بررسی، نمونه فضایی استاندارد 900 اشری با کاربری مسکونی در نظر گرفته شد. در ابتدا، مدل روی سطح زمین مستقر و مصرف انرژی آن معادل 424/0 مگاوات ساعت بر مترمربع مشخص شد. سپس نمونه در گام های متوالی و مساوی 5/0، 1، 5/1، 2، 5/2 و 3 متری در عمق زمین واقع و در هر گام مصرف انرژی مشخص شد. یافته ها: یافته ها نشان داد که در عمق های یادشده، به ترتیب معادل 51/14، 38/28، 56/44، 25/57، 70/74 و 07/79 درصد نسبت به حالت اولیه نیاز سالانه انرژی نمونه کاهش یافته است. از طرفی میزان انتشار آلاینده دی اکسید کربن در محیط نیز به ترتیب معادل65/0 و 27/1 و 99/1 و 57/2 و 35/3 و 55/3 درصد کاهش یافته است. بحث و نتیجه گیری: استقرار ساختمان درون زمین، انتشار آلاینده دی اکسید کربن در محیط را کاهش می دهد.
Background and Objective: The thermal behavior of underground buildings is different from that of above ground buildings. The approaching temperature of the inner layers of the earth to the average annual outdoor temperature reduces the heat exchange of these buildings compared to buildings on the ground. Reducing energy consumption reduces greenhouse gas emissions. The purpose of this study is to evaluate the feasibility of using geothermal energy in buildings to reduce carbon dioxide emissions in the city of Hamedan with cold climatic conditions in 2019. Method: The simulation was performed by using version 8-1-0 of Energy Plus software. In the model, a standard 900 Ashrae sample space with residential usage was considered. At first the building was located on the ground as default and its energy consumption was set to 0/424 MWh /m2. In later stages, the sample is gradually placed in depth in successive steps equal to 0.5, 1, 1.5, 2, 2.5 and 3 meters. Findings: findings showed that in each depth, 14.51%, 28.38%, 44.56%, 57.25%, 74.70% and 79.07% of the annual energy requirements of the sample space has been reduced. On the other hand, in each scenario, the carbon dioxide pollutant emissions as the main greenhouse gas, has been declined to 0.65, 1.27, 1.99, 2.57, 3.35 and 3.55 percent, respectively. Discussion and Conclusion: Therefore, It was concluded that Placement of buildings under the ground reduces carbon dioxide pollutant emissions in environment.
