Manufacturing Infrastructure Adapts to Smaller-Diameter, Inner-Grooved MicroGroove Copper Tubes and Coils as Industry Transitions to Low-GWP Refrigerants

Flexibility and Versatility of Production Lines Is a Major Advantage of Equipment for Making Coils from Smaller-Diameter Copper Tubes   

New York, New York (March 25, 2015) – The International Copper Association (ICA) and Optimized Thermal Systems, Inc. (OTS) today announced that newly developed MicroGrooveTM correlations will be implemented in CoilDesigner® software, a proprietary heat exchanger simulation and design optimization tool developed by the Center for Environmental Energy Engineering (CEEE) at the University of Maryland. Research at the Shanghai Jiao Tong University (SJTU) resulted in the development of new airside and refrigerant-side correlations, particularly for 5-mm MicroGroove tubes.

New York, New York (March 25, 2015) – The International Copper Association announced today that simulations of the inner-grooves of MicroGrooveTM copper tubes can now be accomplished using CoilDesigner®, a proprietary heat exchanger simulation and design optimization tool developed by the University of Maryland. Thanks to new developments by the ICA and Burr Oak Tool, Inc. (BOTI), and implemented by Optimized Thermal Systems, Inc. (OTS) into the CoilDesigner® software, the effects of specific types of surface enhancements now can be simulated.

Inner Fins Boost Heat Transfer and Reduce Materials Usage New York, New York (December 17, 2014) – According to the International Copper Association, internal surface enhancements, or “inner fins” on tubes, substantially increase internal heat transfer coefficients (HTCs) of smaller diameter copper tubes in evaporator and condenser coils as well as gas coolers.

MicroGroove Tubes Made from New Copper Tube Alloys Provide High Strength and High Thermal Conductivity, Minimizing Wall Thickness and Materials Usage New York, New York (December 17, 2014) – According to the International Copper Association, technical tube alloys provide yet another advantage for users of MicroGroove technology, especially in ACR applications using high-pressure refrigerants such as R744 (i.e., carbon dioxide).

Free Webinar in the MicroGroove Webinar Series Slated for January 20, 2015 New York, New York (December 3, 2014) – The International Copper Association and the Copper Alliance announce a New Webinar in the MicroGroove Series of Webinars will be presented on 20 January 2015 at 11:00 am (Eastern Time). The webinar is titled "The Manufacture of High-Efficiency Coils with MicroGroove Copper Tubes" and it will be presented by Brian McConnell, President of Burr OAK Tool Inc.

Montreal, Quebec (May 12, 2014) – As the number of applications for MicroGroove Technology continues to grow, so too does the need for research to guide engineers in the design of industry-first products.
