Abstract
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 compared with the calculation result based on the previous proposed method to predict the initial crystal growth period. The growth of ice column was calculated and the thickness and density were fitted to match calculation to experiment.
