How can you optimize the operation of your cooling system? Mark Donoghue, director at DHD Cooling, says it really just comes down to a few simple things.
According to Donoghue, here is what you can do to improve your cooling system’s performance.
Keep It Clean
The heat transfer surfaces in evaporative cooling towers are designed to maximize the surface area of the circulating water. Heat can be removed by bringing air into contact with the water for evaporation to occur.
Fill is used in evaporative cooling towers to increase the water-contacted surface area. The main types of heat transfer surfaces are splash or film fills. The type of fill used usually is selected depending on the cleanliness of the water, which is why knowing the circulating water quality is a critical factor in cooling tower design.
Maintain Optimum Fluid Flows
Heat transfer design assumes an even distribution of fluid flows across the surfaces of the heat exchanger. Through testing and experience, designers then apply corrections to the mathematical formulas to allow them to guarantee heat exchanger performance.
Ensure Mechanical Components Are in Good Working Order
Cooling systems function by continually moving the heat transfer fluids around. Fans and pumps are designed to overcome system pressure to move fluids, but changes in system pressure can lead to operating conditions that adversely affect these systems. Pump cavitation can destroy impellers, and poor airflow conditions for fans can result in mechanical vibration that can damage rotating machinery over time.
Evaluate and Service
Evaluating your systems will allow you to consider whether your cooling plant is running at optimum efficiency. Cleaning and mechanical maintenance are vital to ensure stable long-term operation and should not be overlooked in order to ensure optimum performance.
