NEW YORK — The International Copper Association (ICA) and Optimized Thermal Systems Inc. (OTS) announced that newly developed MicroGroove™ small-diameter copper tube 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. To make such correlations readily available to HVACR system designers and heat exchanger engineers, the ICA worked with OTS to implement the newly developed correlations into its software design tool.

CoilDesigner is a customizable software tool that allows designers to simulate and optimize the performance of heat exchangers. OTS has an exclusive license agreement with the University of Maryland to provide customized versions and assist in the development of the CoilDesigner software. OTS actively works with various HVACR designers around the globe to optimize heat exchanger geometry, including investigation of the use of small diameter tubes.
