Cooling Towers operation is affected by wet bulb temperature. Wet bulb temperature is measured by using dry bulb temperature, humidity and atmospheric pressure.
The efficiency of the cooling tower will affect the efficiency of the refrigeration system. The water exit or the discharge pressure (if evaporative) should be controlled based on the wet bulb temperature.
The benefits of controlling the Cooling Tower/evaporative condenser based on wet bulb include:
Energy efficiency: By controlling based on wet bulb temperature, the cooling system can operate at higher efficiency, reducing the energy consumption required to maintain the desired temperature.
Improved equipment lifespan: By reducing the workload on cooling equipment, the lifespan of the equipment is extended, reducing maintenance and replacement costs.
Cost savings: By reducing the energy consumption of the cooling system, operational costs are reduced, providing significant savings over time.
Environmental benefits: By reducing the energy consumption of the cooling system, greenhouse gas emissions are reduced, contributing to decarbonisation efforts.
Improved process control: By controlling the temperature of the cooling system, the industrial process can be more precisely controlled, leading to improved product quality and consistency.
