New Developments Favor the Use of MicroGroove Smaller Diameter Copper Tubes, Says the International Copper Association

MicroGroove is the New Benchmark for Energy Efficient Coils

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.

Copper is Well-Suited for Eco-Friendly Refrigerants, Says the International Copper Association

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

MicroGroove Manufacturing Processes and Equipment Are Ready for Production, Says the International Copper Association

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

CoilDesigner Software Can Now Simulate the Performance of MicroGroove Smaller-Diameter Copper Tubes, Says Copper Alliance and Optimized Thermal Systems

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.

Heat Exchanger Design Software CoilDesigner® Now Encompasses Variations in Inside-Tube Surface Enhancements, Says the International Copper Association

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.

Internal Surface Enhancements Boost Efficiency of Smaller Diameter Copper Tubes, Says International Copper Association

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.

Smaller-Diameter Copper Tubes Strengthened with Low Percentages of Alloying Elements Withstand the Higher Pressures of New Refrigerants such as R744, Says the International Copper Association

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).
