CONFERENCE PAPER SESSION 2 (INTERMEDIATE)

HVAC Refrigerants

Track: Fundamentals and Applications

Room: Empire (Lobby)

Sponsor: 08.04 Air-to-Refrigerant Heat Transfer Equipment

Chair: Steve Kujak, Member, Ingersoll Rand, La Crosse, WI

Characterizing the compatibility and performance of new and existing materials for use in HVACR systems is a significant design challenge. New materials like nano-sized particles and new low global warming potential (GWP) refrigerants present new and unique challenges to the performance and reliability of HVACR systems. This session presents a historical overview of chemical stability and materials compatibility challenges for HVACR systems, experimental chemical stability investigations of materials with next generation low GWP refrigerants and the impact of nano-sized particles of Al2O3 on the heat transfer performance and properties of oil-refrigerant mixtures.

1. A Historical Perspective of Refrigerant Chemical Stability and Materials Compatibility for HVAC&R Systems (CH-15-C006)

Steve Kujak, Member, Ingersoll Rand, La Crosse, WI

2. Chemical Compatibility of Low GWP Refrigerants with HVAC&R System Materials (CH-15-C005)

Elyse Sorenson, Member1 and Julie Majurin1, (1)Ingersoll Rand, La Crosse, WI

3. Experimental Investigation on Heat Transfer and Thermophysical Properties of Mixtures of Al2O3 Nanolubricants and Refrigerant R410A (CH-15-C007)

Andrea A. M. Bigi, Student Member1, Thiam Wong, Student Member1, Amy Wong, Student Member1 and Lorenzo Cremaschi, Ph.D., Member1, (1)Oklahoma State University, Stillwater, OK

Chair: Edward A. Vineyard, P.E., Member, Oak Ridge National Laboratory, Oak Ridge, TN

The objective of this seminar is to present current information on alternative refrigerants under consideration in residential refrigerators. This includes information on performance, stability, flammability, component design changes and future EPA regulations.

1. Cycle Efficiency, Charge Minimization, and Service of Household Refrigerators with R-600a

Brent Junge, P.E., Member, General Electric, Louisville, KY

2. A Performance Comparison of R-1234yf and R-134a in Residential Refrigerator Applications

Monday, January 26, 9:45 AM-10:45 AM

SEMINAR 30 (INTERMEDIATE)

What the F-gas Is Going on in Europe: What the HFC Phasedown Means for Our Industry

Track: Systems and Equipment

Room: Honore Ballroom (Lobby)

Sponsor: 02.05 Global Climate Change, MTG: Low GWP Alternative Refrigerants, 08.02 Centrifugal Machines

Chair: Eric Sturm, Member, Trane, La Crosse, WI

The European Union (EU) has modified its rules and regulations on the use of fluorinated gas (F-gas), including hydrofluorocarbons (HFCs). The implementation of the new F-gas regulation began on January 1, 2015. This seminar prepares attendees for the rollout of the new regulations. It details the changes made to the F-gas regulation, outlines the requirements for importers and producers, and discusses the implications of the bans and phasedowns on the refrigerating and air-conditioning markets. Additionally, the seminar also addresses the effect of the F-gas legislation on other regions of the world.

1. The New F-Gas Rules in Europe: Challenges and Opportunities for Industry

Andrea Voigt, The European Partnership for Energy and the Environment, Brussels, Belgium

2. The Impact of New F-Gas Regulations for Producers and Importers of Materials and Equipment; Implications of Revised European F-Gas on Producers

Matthew Ritter, Member, Arkema Inc., King of Prussia, PA

3. Implications of the Revised F-Gas Regulations on Manufacturers Producing for the European Market

William F. McQuade, Johnson Controls Corporation, York, PA

WORKSHOP 3 (INTERMEDIATE)

Code and Safety Standard Requirements: Working with 2L Low GWP Refrigerants

Track: Life Safety

Room: State Ballroom

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 low GWP refrigerants of classification 2L (flammable with burning velocity below 10 cm/sec). We invited two panel members that are experts in the ASHRAE standards process and ASHRAE's role in other standard-making bodies. The panel also discusses potential obstacles moving forward and work that still needs to be done. 

 

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

SEMINAR 48 (ADVANCED)

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

Track: Systems and Equipment

Room: Red Lacquer Room

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 the 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.

1. Standards Development for 2L Flammable Refrigerants

Brian Rodgers, Member, Underwriters Laboratories, Northbrook, IL

2. Product Design Considerations for 2L Refrigerants

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

3. Update on Research to Support Implementation of 2L Refrigerants

Steve Kujak, Member, Ingersoll Rand, La Crosse, WI

4. 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

5. 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
