Experimental Study on Performance of Lightweight Radiant Floor Cooling Combined with Underfloor Ventilation System

Experimental investigations were carried out to study the performance of lightweight radiant floor cooling combined with underfloor ventilation (LRFCUV) system. Operating parameters of LRFCUV system were recorded. Operating characteristic, heat-transfer capability, and thermal comfort of LRFCUV were analyzed based on experimental data. Experimental results indicate that thermal resistance of lightweight floor structure is considerable. Radiant heat-transfer capability occupies approximately 30 % of the total, and LRFCUV system shows fine thermal stability and thermal comfort.
