【Abstract】 The effects of frosting on the heat transfer characteristic of the finned-tube heat exchanger are presented at first, then the improved structure is given to the evaperator when frosting, so that it will prolong the defrosting period, improving the heat transfer performance of the heat exchanger and saving energy and materials. Improvement for the defrosting equipment and the configuration of heat exchanger in different temperature range is especially stated.更多还原
