Abstract:
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 ۳۱۴۸ standards. The experimental results underscore a significant efficiency downturn: sediment presence increased pressure drop by up to ۱۰.۵% and reduced surface temperature by as much as ۱۳%. Notably, heat output initially saw a slight increase, only to decrease by up to ۲۸.۵% 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.
