Radiant Floor Cooling System

In this paper, an experimental study on radiant floor cooling integrated with underfloor ventilation (RFCUV) system was conducted. Indoor environment temperatures, radiant floor cooling system parameters and underfloor ventilation system parameters were measured. Humane thermal comfort was analyzed experimentally. And the effects of disturbance variables and manipulated variables on controlled variables were analyzed. The results illustrated that operative temperature (OT), predicted mean vote (PMV) and predicted percent dissatisfied (PPD) decrease in the first two hours and then become stable in ISO7730 recommended value range. IAT and OT increase with the increasing of the disturbance variables and manipulated variables. The increasing ratio of indoor air temperature (IAT) and OT are relatively small when comprehensive outdoor air temperature is relatively high and indoor heat quantity or average water temperature is relatively low. IAT and OT increase approximately linearly with the increasing of supply air temperature.

Frosting on the surface of a heat exchanger degrades its cooling efficiency in a cooling system. In this study, frost flow analysis is performed for frost reduction. A new type of air blast refrigerator is designed for reducing frost formation in its finned tube. Experimental results of the frost formation in the air blast refrigerator are presented. The main difference between the proposed and conventional air blast refrigerators is the flow of air through the finned tube. The proposed refrigerator produces less frost than the conventional refrigerators.
