Air conditioning
Air conditioning and heating in buildings and motor vehicles are two of the largest applications for heat exchangers. While copper tube is used in most air conditioning and refrigeration systems, typical air conditioning units currently use aluminium fins. These systems can harbor bacteria and mold and develop odors and fouling that can make them function poorly. Stringent new requirements including demands for increased operating efficiencies and the reduction or elimination of harmful emissions are enhancing copper's role in modern HVAC systems.
