چکیده
محدودیت در وجود سوخت های فسیلی و آلودگی هوا یکی از مشکلات اصلی بشر در جامعه امروزی می باشد. سیستم های غیر فعال خورشیدی یکی از موثر ترین راه کارها، برای جلو گیری از آلودگی هوا و کاهش مصرف سوخت های فسیلی است. پژوهش حاضر به بررسی آسایش حرارتی یک دیوار ترومب رو به جنوب در 5 نقطه‌ی استان یزد شامل شهرستان‌های ابرکوه، بافق، میبد، مهریز و یزد در ماه‌های فصل زمستان پرداخته است. ارزیابی میانگین انرژی دریافتی در سطح زمین، ساعات آفتابی و متوسط دمای هر نقطه، توسط داده‌های 3 ساعته سینوپتیک بین سالهای 1393 تا 1398 انجام شده است. با استفاده از داده‌های هواشناسی و محاسبات انجام شده توسط نرم‌افزار EES اطلاعات، وارد نرم‌افزار فلوئنت و انرژی قابل دریافت توسط فلوئنت در تابش‌های مختلف بدست آمده است. بر اساس محاسبات انجام شده، به ترتیب میبد، مهریز، بافق، ابرکوه و یزد دارای بهترین راندمان آسایش حرارتی می‌باشند و در این شهرستان‌ها پس از انجام شبیه‌سازی، دمای ایده‌آل برای انسان حاصل شده است.

چکیده English

Limitations on fossil fuel resources and air pollution are among the main human problems in today's society. Passive solar systems are one of the most effective ways to prevent air pollution and reduce fossil fuel consumption. The current research has investigated the thermal comfort of a trombe wall facing south in 5 places of Yazd province including Abarkoh, Bafaq, Meibod, Mehriz and Yazd cities in the winter months. The evaluation of the average energy received on the surface of the earth, sunny hours and average temperature of each point was done by 3-hour synoptic data between 2013 and 2018. Using the meteorological data and calculations made by the EES information software, entered into Fluent software and the energy received by Fluent in different radiations has been obtained. Based on the calculations, Meybod, Mehriz, Bafaq, Abarkoh and Yazd respectively have the best thermal comfort efficiency and in these cities, after simulation, the ideal temperature for humans has been achieved.
