In a direct evaporative cooler, dry air is passed by a water reservoir to evaporate water into the air, causing the latent heat of vaporization to be absorbed from both the air and the water; this results in the air leaving the cooler at a lower temperature, as desired. An image for this process is below:
In the type of recirculating cooling tower typically connected to the condenser of a thermoelectric power plant (image below), dry air is passed by hot water coming from the power plant's condenser. This causes water to evaporate into the air, absorbing the latent heat of evaporation from the water and the air, resulting in a lower water temperature, as desired.
The thing that is confusing me is the fact that evaporation of water into air in the direct evaporative cooler (first image) causes the air to leave the cooler at a lower temperature, but in the recirculating cooling tower, the air leaves at a higher temperature than it came in at. My questions are as follows:
1) What is the main reason for the difference in air temperature leaving each of the respective cooling systems?
2) Is the higher temperature of the air leaving the cooling tower due to sensible heat transfer (from warm water to cooler air) in excess of absorption of latent heat from the air?
