Refrigerants and Secondary Coolants
ASHRAE Technical Committee 3.1

Meetings Information

Las Vegas Meeting, January 2017

TC 3.1 is co-sponsoring the following technical sessions at the Las Vegas Winter Meeting 

Seminar 39: Low-GWP Alternative Refrigerants and Their Applications: Part 1

Chair: J. Steven Brown, Ph.D., P.E., The Catholic University of America, Washington, DC

The seminar addresses low-GWP alternative refrigerants and their applications. As regulations and legislation become increasingly more widespread and restrictive, the HVAC&R industry will need to identify viable alternatives for existing refrigerant solutions. This environmentally-driven change is different than past ones since additional constraints are being placed on refrigerants in essence reducing the number of viable single-component solutions. The seminar highlights five papers appearing in ASHRAE’s Science and Technology for the Built Environment November 2016 edition (one dedicated specifically to low-GWP refrigerants.) The presentations focus on low-GWP halocarbon refrigerants containing unsaturated carbon bonds during boiling heat transfer and in system applications.

1. Oil Retention of Lower GWP Refrigerants and Lubricant Mixtures and Its Effect on Heat Transfer and Pressure Drop in Microchannel Type Air Conditioning Evaporators

Lorenzo Cremaschi, Ph.D., Member, Auburn University, Auburn, AL

2. Miscibility of POE and PVE Oils with Low-GWP Refrigerant R-1234ze(E)

Man-Hoe Kim, Ph.D., Member, Kyungpook National University, Buk-gu, Daegu, South Korea


Seminar 56: Low-GWP Alternative Refrigerants and Their Applications, Part 2

Attend a Committee Meeting

ALL ASHRAE committee meetings, including this TC’s meetings at the Winter and Annual Society conferences, are open to the public at no cost nor is conference registration required. Interested visitors, local chapter members, and potential new TC members are always welcome. However to attend technical program sessions sponsored by the TC will require registration and payment of any applicable fee.

Participation in an ASHRAE TC provides the opportunity to grow professionally and to contribute to the advancement of HVAC&R within an international organization recognized for shaping the future of the built environment through research, standards writing, publishing, and education.
