The Experiment Research about the Condensation Prevention in the Radiant Cooling Panel

Abstract:

This paper study some types of the condensation prevention measures in the radiant cooling board. The test bench for its surface condensation's performance is designed and built. In the experiment, four different types of radiation board, which are the grooved surface, Teflon coating surface, super-hydrophobic coating surface and the grooved surface pasted by the PTFE membrane, are investigated. The visual camera is used in observing the condensation process. It is found that: though both the Teflon coating and the super-hydrophobic coating treatment all can reduce the drop fall-off diameter effectively. Further, the super-hydrophobic coating treatment also can delay the fall-off time. The radiant cooling surface, by the measure of the grooved surface pasted by the PTFE membrane, can keep dry continuously. This work may lay the foundation for the simplification of the radiation cooling air conditioning system.
