The scope of application of cooling towerIndustrial production or refrigeration technology produces in the process of waste heat, general with cooling water to the go. Cooling tower is the role of the cooling water waste heat traps in the tower and air for heat exchanger, make the waste heat transmission to the air and scattered into the atmosphere.work principle:Cooling towers are using water and the air contact, through the evaporation to disperse industry or refrigeration and air conditioning in the produce of waste heat of a device. The work principle is: dry (low enthalpy) for air after fan after the twitch, since into wind nets place into the cooling tower; Saturated steam partial pressure of high temperature water molecules to the low pressure air flow, hot and humid (high enthalpy) of water from water system was sprinkled into the tower. When water and air contact, on the one hand, because of the air and water direct heat transfer, on the other hand because water vapor surface and air pressure difference between the pressure being under the function of evaporation phenomenon, namely the quantity of heat of water evaporation heat transfer away, so as to achieve the purpose of cooling.
