Summary

To reduce and avoid the frost on the cold fan surface is one of the most important way to improve the efficiency of the refrigeration system in the cold room. In the paper, the effect of different magnetic intensity on the condensing temperature and the freezing temperature of the wet air with a relative humidity of 45% and an initial temperature of 25°C were studied under the condition of a temperature decreasing rate of 5°C /min and the end temperature of -20°C. The results shown that frost formation process included five stage, such as the condensation, the combination and growth, shrink and taller, freezing and frost formation. As the magnetic field intensity increases gradually, the degree of undercooling gradually increases, the amount of frosting decreases, and the amount of frosting has a linear relationship with the intensity of the magnetic field.
