Types of Industrial Cooling Systems

What this topic covers

Air-cooled, evaporative, closed-loop liquid, chilled-water, refrigeration and hybrid systems.

Core thermal ideas

Air-cooled systems reject heat directly to ambient air without evaporating water.

Cooling towers and evaporative systems use evaporation to achieve lower water temperatures than dry air cooling may provide under the same conditions.

Chillers and refrigeration systems can provide coolant below typical ambient wet-bulb limits at the cost of additional equipment and energy.

System tradeoffs

Temperature difference drives heat transfer, while flow, area, fouling and thermal resistance determine how easily heat can move.

What to monitor

Water chemistry, refrigerants and process fluids require site-specific safety and environmental controls.

Lifecycle perspective

A lifecycle view includes energy, water, maintenance, fouling, reliability and future load—not only nameplate cooling capacity.
