Abstract
Indoor air temperature, floor temperature, and wall surface temperature were measured when lightweight radiant floor cooling combined with underfloor ventilation (LRFCUV) air conditioning system and heavy radiant floor cooling combined with underfloor ventilation (HRFCUV) air conditioning system operated. And indoor air temperature field, heat-transfer capability, and thermal comfort were analyzed. Experimental results show that LRFCUV air conditioning system started up faster than HRFCUV air conditioning system. When the system reached stable condition, net radiant floor heat quantity of HRFCUV air conditioning system was larger than that of LRFCUV air conditioning system, and thermal comfort of HRFCUV air conditioning system was better than that of LRFCUV air conditioning system.
