| چکیده | ||
| In this investigation, we present pioneering findings on the detrimental effects of sediment deposits on the thermal and hydraulic performance of residential heating radiators through a novel experimental framework. Our approach, through the systematic introduction of particulate matter into the water circuit, quantifies the real-world impact of sediment accumulation. This methodology fills a significant void in literature with validated experimental data and establishes a method for assessing radiator performance under fouled conditions, adhering to ISO 3148 standards. The experimental results underscore a significant efficiency downturn: sediment presence increased pressure drop by up to 10.5% and reduced surface temperature by as much as 13%. Notably, heat output initially saw a slight increase, only to decrease by up to 28.5% over time, with these effects amplifying at higher inlet temperatures. These findings underscore the urgent need for tailored maintenance strategies to combat sediment-related degradation, offering invaluable insights for the design, maintenance, and optimization of heating systems beneficial to both industry stakeholders and end-users. | ||

| چکیده [English] | ||
| در این پژوهش، یافتههای نوآورانهای در مورد اثرات مخرب رسوبات بر عملکرد حرارتی و هیدرولیکی رادیاتورهای گرمایشی مسکونی از طریق چارچوب تجربی بدیع ارائه شده است. رویکرد ما، از طریق معرفی سیستماتیک مواد ذرهای به مدار آب، تاثیر واقعی تجمع رسوب را کمیسازی میکند. این روششناسی، با دادههای تجربی تایید شده، خلأ قابل توجهی در تحقیقات موجود را پر میکند و روشی برای ارزیابی عملکرد رادیاتور تحت شرایط آلوده مطابق با استانداردهای ISO 3148 ارائه میدهد. نتایج تجربی، کاهش قابل توجهی در کارایی را نشان میدهد: حضور رسوب، افت فشار را تا 10.5٪ افزایش داده و دمای سطح را تا 13٪ کاهش داده است. به طور قابل توجهی، خروجی حرارتی در ابتدا شاهد افزایش جزئی بود، اما با گذشت زمان تا 28.5 درصد کاهش یافت، این تاثیرات با افزایش دمای ورودی بیشتر تشدید میشود. این یافتهها، نیاز فوری به استراتژیهای نگهداری متناسب برای مقابله با تخریب مرتبط با رسوب را برجسته میکند، بینشهای بینظیری برای طراحی، نگهداری، و بهینهسازی سیستمهای گرمایشی ارائه میدهد که به نفع ذینفعان صنعت و کاربران نهایی است | ||
