Abstract
According to experiment phenomena and data, which were about the influence of air in-leakage upon the condenser performance, the relations between the condenser pressure, heat transfer coefficient, terminal temperature difference and the air mass ratio were revealed in figures and tables. The critical values when the three parameters vary along with the air mass ratio were obtained. When the air mass ratio is smaller than its critical value, the pressure and terminal temperature difference increase slightly with the increase of air mass ratio. Accordingly the heat transfer coefficient decreases slightly with the increase of air mass ratio. When the air mass ratio is larger than its critical value, the pressure and terminal temperature difference increase rapidly with the increase of air mass ratio. And accordingly the heat transfer coefficient decreases rapidly. Moreover, the critical values for different parameters that vary with the air mass ratio are different, but all critical air mass ratios are about 1%.
