چکیده مقاله :
امروزه، با اعمال روشهای نوین، میتوان درصد بالایی از سوخت برای تأمین گرمایش و یا سرمایش مناسب ساختمان روستایی و شهری را کاهش داد. این روشها هنوز هم تحت مطالعهاند و باید با بررسی دقیق آن ها و اعمال شیوههای نوین از مصرف بیرویه انرژی را در ساختمانهای شهری و روستایی کاهش داد می توان با محاسبات دقیق این میزان تا 50 درصد تغییر داد. هدف مقاله براورد میزان روزهای سرمایش و گرمایش سالانه (HDD وCDD ) مقایسه میزان نیاز مصرف گاز شهر انزلی با هزینه براوردی آن است.روش تحقیق استفاده از محاسبه درجه روز های سرد و گرم ابداعی فرمول دکتر خلیلی است که با استفاده از محاسبه میزان سرمایش و گرمایش ممکن میگردد ابزار آن داده های هواشناسی و فرمول پیشنهادی آن در یک دوره زمانی 34 ساله ( 92 - 1358 ) درجه حرارت ایستگاه انزلی استفاده شده است. نتایج تحقیق نشان داد نیاز به درجه - روز گرمایش به میزان 1546.42 درجه-روز و درجه – روزه ای سرمایش به اندازه ی 94.55 درجه می باشد و نیاز به انرژی گرمایش برای یک ساختمان مسکونی با 100 متر مربع و با ارتفاع 2.7 متر به 15657300 ریال و در فصل گرم به 957.3 ریال دارد. نتایج این تحقیق می تواند کمک به برنامه ریزان منطقه ای و محلی در رابطه با قیمت واقعی هزینه مصرف گاز و پهنه بندی ضریب آن نماید .
Nowadays, by applying new methods, a high percentage of fuel can be reduced to provide adequate heating or cooling for rural and urban buildings. These methods are still under study and should be reduced to 50% with accurate calculations by carefully examining them and applying new ways to reduce excessive energy consumption in urban and rural buildings. The objective of this paper is to estimate the annual cooling and heating amount (HDD and CDD) in comparing the need of Anzali city gas consumption with its estimated cost. The research method uses the calculation of the warm and cold days by Dr. Khalili's inventive formula, which is possible by using calculated cooling and heating rate. The instrument of this meteorological data and its proposed formula were used during a 34 year period (1979-2013) of Anzali station temperature. The results of this study showed that the need for the heating day is 1546.42° -day and the degree-cooling day is 94.55°, and the need for heating energy for a residential building with 100 m² and 2.7 meters height is 15657300 Rials and in the heating season it is 957.3 Rials. The results of this research can help local and regional planners in relation to the actual cost of gas consumption and the zoning of its coefficient.
