ASHRAE Technical Committee 3.3 - Refrigerant Contaminant Control


HOME


Welcome to the homepage of the ASHRAE Technical Committee 3.3. This technical committee is concerned with sources, generation, and control of water and other contaminants in refrigerating systems.

 

Do you want to get involved in your TC's issues at the Society level? If so, read through the pages of this site, attend the annual meeting, or contact our Committee Chair or a subcommittee member. 


MEETINGS at Winter Meeting, Chicago, January 2015

 

Main committee meeting:

 TC 3.3 Refrigerant Contaminant Control - Tuesday, January 27, 3:30-6:00 pm

WORKSHOP (INTERMEDIATE)

Code and Safety Standard Requirements: Working with 2L LGWP Refrigerants

Track: Life Safety

Sponsor: 03.01 Refrigerants and Secondary Coolants, MTG LowGWP

Chair: Robert G Richard, Member, Honeywell Int. Inc., Buffalo, NY

This session looks at code and standard requirements for implementing the LGWP refrigerants of classification 2L (flammable with burning velocity below 10 cm/sec). We have invited two panel members that are experts in the ASHRAE standards process and ASHRAE's role in other standard making bodies. The panel also will be able to discuss potential obstacles moving forward and work that still needs to be done. 

 Tuesday, January 27, 11:00 AM-12:30 PM

SEMINAR (ADVANCED)

International Codes and Standards Issues Impacting use of A2L Refrigerants in Unitary Heat Pump and Air-Conditioning Equipment

Track: Systems and Equipment

Sponsor: 08.11 Unitary and Room Air Conditioners and Heat Pumps, 03.01 Refrigerants and Secondary Coolants

Chair: Van D. Baxter, P.E., Fellow ASHRAE, Oak Ridge National Laboratory, Oak Ridge, TN

International efforts to address climate change are putting pressure on the HVAC&R industry to limit use of HFC refrigerants that have relatively high global warming potential (GWP) and transition to equipment designed around low GWP alternatives. To meet this challenge without compromising energy performance, companies are evaluating use of mildly flammable (A2L) refrigerants. The presentations discuss recent activities to modify product safety standards to facilitate A2L use, recent R&D advances on A2L refrigerants and A2L implications for unitary product designs. An update on the impact of F-gas regulations on heat pump refrigerant options in Europe is also provided.

Standards Development for 2L Flammable Refrigerants

Brian Rodgers, Member, Underwriters Laboratories, Northbrook, IL

Product Design Considerations for 2L Refrigerants

Paul Papas, Ph.D., United Technologies Research Center, East Hartford, CT

Progress in Drafting Amended Wording for Safety Standards to Accommodate the Use of A2L Refrigerants

Dutch Uselton, P.E., Fellow ASHRAE, Lennox Industries, Carrollton, TX

Availability of Refrigerants for Heat Pumps in Europe

Rainer M. Jakobs, P.Eng., Member, Information centre on Heat pumps and Refrigeration, IZW e.V., Breuberg, Germany
