The Development and Summer Test of a New Ceiling Radiant Cooling Panel

Abstract:

The main application problems of radiant panel in summer include lower cooling capacity owing to high temperature of water supply and condensation. A new radiant panel was developed. Water duct and panel are straight forming which eliminates the thermal contact resistance .The panel are installed in an angle in order to discharge condensate water. The guiding gutter in the face of panel and condensate pipe are to collect and outlet condensate water. The summer test was done. The results show that the new radiant panel has higher cooling efficiency compare with conventional panel .The cooling efficiency is above 1000w/m2, and condensate water can be discharged quickly. Although new Ceiling Radiant Cooling Panel is still not perfect, but it is provides us with more choice.
