Experimental and Numerical Study of Radiant Floor Heating Panels Performance at Different Conditions

Abstract

The performance of radiant floor heating panels with different arrangements in room and different room air temperatures are investigated experimentally and numerically. In addition to study the effect of radiant floor heating arrangement on thermal comfort conditions in occupied zone. The room air and panels temperatures are measured at different heights and locations. The temperature of supplying hot water fluctuates from 35 to40 °C. The results present that the different radiant floor heating arrangements effect on thermal comfort while the performance of radiant floor heating panel is little affected by arrangements. Experimental results appear good agreement with numerical results.

Numerical simulation of the influencing factors of radiant floor heating system

“…The reality of heating is complicated, which has different immanent factors (such as heat supply, heating floor structure, envelope structure, room structure and so on) and external factors (such as neighbor situation, outdoor environment, solar radiation, weather condition and so on) 6–8 . The factors are interrelated and all directly or indirectly affect the heating effect of heating system and heat comfort of users.…”

“…The reality of heating is complicated, which has different immanent factors (such as heat supply, heating floor structure, envelope structure, room structure and so on) and external factors (such as neighbor situation, outdoor environment, solar radiation, weather condition and so on). [6][7][8] The factors are interrelated and all directly or indirectly affect the heating effect of heating system and heat comfort of users. Kassim et al 9 used CFD to conduct numerical simulation of floor heating systems in rooms at different locations, and the results showed that both indoor temperature and the position of floor heating panels affect heat comfort.…”
