Cooling towers are an important part of high-output HVAC systems.

HVAC systems in large facilities often need water-cooled cooling towers to reject heat into the atmosphere and allow for energy-efficient operation of refrigerant compressors and water pumps. Although simple in concept, cooling towers are quite complex in their operation. Choosing the correct type of cooling tower is critical. Properly maintaining them will prevent costly facility down time.

This webinar will review the fundamentals of cooling by evaporation and explain the five main tower characteristics: draft, airflow direction, fan location, cooling type and heat transfer media. We will discuss their theory of operation including temperature range, approach and wet bulb. The proper sequence of operations for energy-efficient operation will be explained as well as energy saving opportunities such as increasing wetted surface area and free cooling economizers.

Finally, we will take a brief look at how fans and pumps consume energy and provide numerous tips on cooling tower maintenance. Register today.
