A PRE-COOLING SYSTEM AND METHOD FOR PRE-COOLING AIR

摘要

The present invention provides a simple pre-cooling system and method for pre- cooling air. The pre-cooling system comprising a first stage sensible cooling means for exchanging sensible heat indirectly between water and air to cool air and raising the temperature of the water and a second stage adiabatic cooling means for cooling the air adiabatically by direct contact of water with sub-cooled air from the first stage sensible cooling means. In the method for pre-cooling air, atmospheric air and water indirectly contacted for exchanging sensible heat to cool air and heat water, and directly contacting water and cooled air for adiabatic cooling of cooled air and water wherein air and water are cooled to wet bulb temperature lower than ambient wet bulb by evaporation of less quantity of water.
