Orlando, Florida (22 January 2016) – As industry phases out high-GWP refrigerants and strives for energy efficiency, MicroGroove smaller-diameter copper tubes are now more relevant than ever. The march toward smaller diameter tubes began more than a decade ago and now tube diameters of 5 mm or smaller are commonplace in round tube, plate fin (RTPF) evaporators and condensers. MicroGroove copper tubes are the new benchmark for coils in residential and commercial ACR products.
On the eve of the 2016 AHR Expo, several new developments are contributing to the widespread adoption of smaller tubes.
Copper, of course, is one of the best thermal conductors. Tubes made of copper provide the strength, durability and corrosion resistance that is needed in ACR applications. Furthermore, the RTPF configuration has inherent advantages compared to microchannel or multichannel tubes made of aluminum. Consequently, smaller diameter copper tubes are widely considered to be the new benchmark for many kinds of heat exchanger coils that are used in air-conditioning and refrigeration, including room air-conditioners, split systems, outdoor condensers, beverage coolers, heat pumps, various large commercial applications and more.
“OEMs are discovering that MicroGroove is well-suited for nearly all of their coil application requirements,” says Nigel Cotton, MicroGroove Team Leader for the International Copper Association. “Advances in manufacturing coupled with the phase out high-GWP refrigerants is resulting in widespread adoption of MicroGroove tubes in the ACR industry.
