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. In this paper, operating characteristic, heat-transfer capability, and thermal comfort of LRFCUV were analyzed by experimental investigations. In summary 1. Thermal resistance of lightweight floor structure is considerable. 2. Heat-transfer capability by radiation occupies approximately 30 % of the total under stable operating condition. 3. Indoor air temperature shows uniform distribution and meets thermal comfort request under stable operating condition. 4. Three hours after the system starts operating, both PMV and PPD values are in ISO7730-recommended value range.
