The advantage of water distributed on every tube structure is that water can be distributed on every tube respectively. The influences of the spray water flow rate and the air velocity on the air flow resistance of evaporative condenser with water distributed among the whole tube bundle structure were investigated

and conventional spraying water structure was also adopted to be compared. The experiment was carried out on the condition that the water flow rate was 0.5~1.2 m3/h and the air velocity was 0.5~4.0 m/s. The results show that the air flow resistance of this new structure decreases 11.5% at parallel-flow mode and 49.7% at counter-flow mode respectively. In addition

at counter-flow mode

the air flow resistance increases suddenly when the air velocity is 3.5m/s

which is higher than that of traditional evaporative condenser. Energy-save is about 2%

comparing with the conventional spray water structure when used in refrigeration system.
