Experimental Study of Restraining Frost Formation on Hydrophilic Surface under Natural Convection Conditions

Abstract

A series of tests was carried out on the hydrophilic surface that was made of a new hydrophilic anti-frosting paint with the character of restraining frost growth. Compared the result with prevenient hydrophilic paint, the new paint presented in this paper has better effect on retarding frost formation under low and high relative humidity environment and the thickness of the coat made by the new paint was only 0.06mm, that was only 20 percentage of film thickness of prevenient paint.
