For the improvement of the coefficient of performance of heat exchangers, such as air-conditioners, showcases and unit coolers, under frosting conditions, a clarification of the frost deposition mechanism in a low-temperature environment is necessary. Therefore, frost properties were measured at temperatures below 0℃. The experimental results were analyzed and the calculation model of frost growth in low temperature environments were made. In the calculation model, the ice column growth model of Tao was used at the crystal growth period and Pick's low and Le Gall's model were used at the frost growth period. The experiments results and calculation results were compared, and they were corresponding well.
