Evapco / Evaptech

Principle of Operation:

• A cooling tower is a specialized Heat Exchanger in which two fluids (air and water) are brought into direct contact to effect the transfer of heat thru evaporation
• Cools a recirculating flow of water to which heat has been added by the system served
• Saving the user on water costs
• Hot water from condenser flows over the fill.
• Tower fan draws ambient air across water on the fill.
• Heat from the water is transferred to the air by latent and sensible cooling.

Selection Parameters:

• Flow rate (gpm)
• Hot Water (condenser Leaving Water Temperature)
• Cold Water (condenser Entering Water Temperature)
• Wet Bulb (entering Wet Bulb) Recommend the 0.4% WB from table 1b, Chapter 27, 2001 ASHRAE  Fundamentals
• Range = Hot Water – Cold Water
• Approach = Cold Water – Wet Bulb
