An Introduction to Closed Loop Cooling

What is closed loop cooling? A closed loop cooling system maintains the optimal temperature within a sealed enclosure while keeping out warmer ambient air, humidity, dust, and other airborne contaminants. By circulating cool, clean air within an electrical enclosure (and through heat-producing elements), closed-loop cooling systems help to protect sensitive electronic components, and prolong their lifespan. In a typical closed loop air conditioner, heat is transferred from the enclosure components by circulating air around and through them. The air is then cooled, dehumidified, and returned to the enclosure without the admission of air from outside the enclosure. The heat is removed from this air within the air conditioning unit and discharged by means of a vapor compression refrigeration cycle. This takes place in a hermetically sealed system, utilizing either an air-cooled or water-cooled condenser coil.

To learn more about closed loop cooling with enclosure air conditioners, watch the video below or download our free white paper, Cooling Electrical Enclosures with Special-Purpose Air Conditioners.
