When the temperature and flow velocity of the freestream were 50 ℃ and 10 m/s, respectively, ground experimental studies on frosting and defrosting of the microtubule heat exchanger were carried out, respectively, under the conditions of two different freestream humidity values (1.8 g/kg and 6.4 g/kg). The ground experimental results showed that the freestream humidity value had significant influence on the frosting and defrosting performances of the microtubule heat exchanger. In the frosting experiments, the amount of frost layer increased with the increase of the humidity value of the freestream, but the relationship between them was not proportional. The greater freestream humidity value indicated the lower wall surface temperature of the heat exchanger tube bundle, and the higher growth rate of the pressure loss coefficient of freestream indicated the lower heat transfer rate of heat exchanger. However, in the defrosting experiments, the amount of frost layer and the pressure loss coefficient of freestream did not increase with the increase of freestream humidity value. And with the increase of freestream humidity value, the wall surface temperature of heat exchanger tube bundle increased, and the heat transfer rate of the heat exchanger decreased.
