Microchannel Coils Have Now Been Adapted to HVAC Applications

By Consulting Specifying Engineer Staff February 7, 2006

Carrier Corporation, a unit of United Technologies Corp., has announced the achievement of world class efficiencies of 10.9 EER full-load and 15.4 part-load on air-cooled chillers with non-ozone depleting HFC-134a refrigerant by utilizing microchannel coil technology.

“Microchannel coil technology is widely used in the automotive industry to increase heat transfer efficiency while providing enhanced reliability through improved corrosion resistance,” said David Sabatino, product manager, Carrier air-cooled chillers. “Now, microchannel coils come standard with an industry exclusive three-year coil warranty on all of our Aquaforce models ranging from 80 to 500 tons.”

Carrier claims that in addition to the chiller’s efficiency and improved corrosion resistance using the new microchannel coil technology, the chiller is now even more environmentally sound.

Sabitino explains that the adaption of microchannel coil technology to the commercial HVAC industry was only possible after a boost in efficiency and standardization of the technology.
