The effect of electric field on frosting phenomenon is investigated. It is known that the frost formation on a heat exchanger seriously affects the performance of the system, and that the application of electric field is one of the promising procedures because dielectric water molecules play a role of solidification nuclei. In order to understand the fundamental characteristics of the frosting phenomenon under the electric field, experiments have been carried out. The electric field is applied between the frosting surface and the mesh electrode which is placed in parallel with the surface. The results of experiments reveal that the apparent mass transfer rate is decreased and the heat transfer rate is increased by applying the electric field because the dendritic frost crystal is removed by the strongly imposed electric field.
