Dry Cooling Tower

Dry Cooling Tower is the warm water can be cooled to a temperature lower than the ambient air dry temperature, if the air is relatively dry.Dry cooling tower is drawn past a flow of water, a small portion of the water evaporates, and the energy required to evaporate that portion of the water is taken from the remaining mass of water, thus reducing its temperature of heat energy is absorbed for each pound of evaporated water.

Dry Cooling Tower results in saturated air conditions, lowering the temperature of the water processed by the tower to a value close to wet bulb air temperature, which is lower than the ambient dry bulb air temperature, the difference determined by the initial humidity of the ambient air. Due to the density differential compared to the dry, cooler outside air. Warm moist air is less dense than drier air at the same pressure.

Dry Cooling Tower is buoyancy produces an upwards current of air through the tower.The relative humidity of the dry air is even more decreased instantly as being heated while entering the tower. The discharged mixture has a relatively lower relative humidity and the fog is invisible. The working fluid through a tube bundle, upon which clean water is sprayed and a fan-induced draft applied. The resulting heat transfer performance is much closer to that of a dry cooling tower, with the advantage provided by a dry cooler of protecting the working fluid from environmental exposure and contamination.
