Based on character of host condensator, degreeofsuper-cooling of vacuum-condensed water is researched. System design rule, model and realization method are illustrated in detail.
It can discharge frozen water which is nearly saturated. The degreeofsupercooling is small and there is noaccumulation of water in the heating.
能排除接近饱满和状态的凝结水，过冷度小，加热设备不会有水积聚，能获得最高的加热效率。

According to classical solidification theory and the mechanism of solidification microstructure under pulse current, the effect ofsuper-coolingdegree variation on nucleation rate was discussed.
