Fan and Pad Greenhouse Evaporative Cooling Systems

Evaporative Cooling Evaporative cooling is a process that reduces air tempera-ture by evaporation of water into the airstream. As water evaporates, energy is lost from the air causing its tempera-ture to drop. Two temperatures are important when dealing with evaporative cooling systems—dry bulb temperature and wet bulb temperature.
