Abstract

In this paper, the effects of different initial head-on wind speed and heat exchange temperature difference on the frosting and performance of heat exchanger are studied by using wind tunnel experimental device. The results show that with the frost amount under different initial head-on wind speed and different heat exchange temperature difference increases with the frost time, while the growth rate of frost amount gradually increases with the increase of heat exchange temperature difference. And the refrigeration capacity and heat transfer coefficient almost increased first and then decreased.
