| Abstract: | According to the Devonport correlations,this paper analyzed the effect of face air velocity on the air-side parallel-flow type condenser: the air-side main configuration parameters(fin pitches,fin height,blind pitch and blind angle) of the condenser as well as the pressure drop with different face air velocity play different role in the heat exchange.The study optimize the air-side structures of parallel-flow condenser. |

| Keywords: | parallel-flow type condenser face air velocity pressure drop heat transfer |
