[0002] The evaporative cooling system is a system in which water is in direct contact with air. Under certain conditions, water evaporates to form water vapor, which absorbs heat and lowers the air temperature. The actual result is that both the air temperature and water vapor (including liquid water) are reduced. Currently, evaporative cooling systems all use cooling tower countercurrent heat exchange.
