Open Tower System

Water and air are in direct contact as a shape of pulverize. Evaporation increases depending on the proportion of the increment of water and water's temperature so the efficiency of the system is effected positively. Furthermore, that means the system needs to be given the amount of evaporated water. In order to decrease the 4 - 5 degree  of system's temperature, 1% of water must be evaporated. Cooling can be done until 2 - 3 degree of wet bulb thermometer and this means the significant energy when the temperature of external environment is too low. The capital and operation / maintenance cost of the system less than cooling systems which include compressor.
