Summary

According to the heat transfer between radiant ceiling unit and surrounding environment, theoretical calculation models of single
piece of the capillary cooling radiant ceiling unit and two units in series combination were set up to calculate their cooling capacities
based on the reasonable simplification of configuration of radiant ceilings. The cooling capacities under the condition of 25°C : room temperature, 15-19°C : supply water temperature were then tested. The comparison between measured data and calculation results show that theoretically calculated cooling capacity of single unit and of two series-connected units agree with the experimental testing data, which shows that the theoretical calculation models are reasonable and feasible and can be used to predict the cooling capacities under real conditions.
