In order to improve the performance of chilled radiant panel(CRP) containing air layer

we firstly established a mathematical heat conduction model of CRP with air layer and evaluated its reliability. The deviation of model and experimental results about CRP cooling capacity and surface temperature was 9.20% and 4.00%

which indicated that the model had high reliability. Then we change the contact form of CRP’s chilled water brass and thermal plate by two ways and used the verified model to analyze the performance of the transformed CRPs. The results showed that two CRPs’ cooling capacity increased 36.92 W/m2 and 33.19 W/m2 when the air layer thickness was reduced to 1mm under the optimal parameters; the cooling capacity averagely increased 7.46 W/m2 and 7.54 W/m2 as chilled water temperature decreased per 1 ℃ and indoor temperature increased per 1 ℃; the CRP’s surface maximum temperature difference was constant. In conclusion

CRP containing thin layer has better performance on the cooling and anti-condensation

and it has the potential to be widely used.
