2.1 Cooling Principle:

 1,Working fluid is circulating in evaporative condenser main pipe, the heat is passed through pipe shell, hot humid water and air become a saturated steam, the heat is discharged out by the fan, the water is going back to sink recirculation.Spray water during the cycle reduced by the PVC heat sink temperature, with the formation of fresh air into the wind, the water flow in the same direction, coil mainly rely on sensible and latent hot conduction mode.

   2,Air enter type: The mixed type by water and air
