Three Technical Webinars and Slideshows on MicroGroove Heat Exchangers Is Available Online

The International Copper Association Inc. (ICA) and Optimized Thermal Systems Inc. (OTS) has announced the online accessibility of three technical webinars and slideshows that were the key components of the OTS-ICA technology outreach program.
The three webinars, which were presented in the spring, provide an exploration of MicroGroove technology. Segments include the science behind the advantages of smaller diameter copper tube-fin heat exchangers; the manufacturing technology for the construction of RTPF heat exchangers and effective design practices, including use of simulation software tools for the design of heat exchangers using smaller diameter copper tubes.
The three webinars were presented by:


  • 1. Daniel Bacellar and Dennis Nasuta of Optimized Thermal Systems Inc. together focus on “Advantages of Small Diameter Copper Tube-Fin Heat Exchangers” in the first webinar.

  • 2. Rocky Smith, product manager, coil production, for Burr OAK Tool Inc.; Yoram Shabtay, President, Heat Transfer Technologies, LLC; and Daniel Bacellar of Optimized Thermal Systems Inc. discuss the “Construction of Small Diameter Copper Tube Fin Heat Exchangers” in the second webinar.

  • 3. Dennis Nasuta & Daniel Bacellar cover the “Effective Design of Small-Diameter Copper Tube-Fin Heat Exchangers” in the third webinar.

The webinars and slideshows can be accessed via by selecting OTS-ICA from the menu on the home page.
Anyone can view the webinars and download the slideshows with no registration required. Interested parties are also encouraged to enroll in the OTS-ICA program, which is aimed at engineering students, academic researchers and industry professionals who would like to learn more about MicroGroove technology, a component for ecofriendly HVAC&R applications. 
Viewing the three webinars and completing a survey for each is a prerequisite to gain access to the demonstration and trial versions of CoilDesigner, software developed by the University of Maryland’s Center for Environmental Energy Engineering (CEEE).

CoilDesigner is a proprietary tool for air-to-refrigerant heat exchanger modeling and simulation. Correlations in CoilDesigner allow users to explore the performance of tube-fin heat exchangers with small diameters.  
Interested participants can also request a sample 5-mm heat exchanger for use in instruction or for laboratory testing. Participants who conduct performance tests in their own facilities will be encouraged to share their findings. See the OTS-ICA registration page, or contact OTS directly at [email protected].
The purpose of this hands-on introduction to MGHX technology is to engage people from various institutions and different backgrounds and encourage them to collaborate in advancing the round tube, plate fin (RTPF) heat exchangers. Participants will learn how MicroGroove heat exchangers in HVAC&R equipment contribute to sustainable development of the built environment.
