It has been known that the frost formation on a heat exchanger seriously affects the performance of the system, and that the application of an electric field will be one of the promising procedure because dielectric water molecules play the role of solidification nuclei. In order to understand the fundamental characteristics of the effect of electric fields on the frosting phenomenon, several experiments were earned out. The electric fields were applied between a frosting surface and a mesh electrode which was placed in parallel with the surface. The experimental results revealed that the electric fields affect the frosting pattern especially a dendritic growth during the early period of the frosting and the frosting rate is gradually decreased by increasing the electric field strength up to a certain value. After this critical value, the frosting rate is increased by increasing the field strength, because the corona wind is generated above this value. Moreover, the wettability of the frosting surface under electric field did not affect the frosting characteristics by comparing the results of copper and PTFE cases which were used as frosting surface material.
