Donation will help fund research of 2L mildly flammable refrigerants
August 1, 2016
Johnson Controls has donated $100,000 to ASHRAE Research. The donation will help fund research that supports the development of safety standards regarding the use of mildly flammable, low-global warming potential (GWP) refrigerants.
Includes recommended practices for flammable refrigerant containers
July 14, 2016
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published updates to AHRI Guideline Q, Content Recovery and Proper Recycling of Refrigerant Cylinders, which now includes best practices for end-of-life recycling of flammable refrigerant containers.
We all know that some of the new refrigerant options are highly flammable, some are mildly flammable, and some operate at very high pressures. But our industry is filled with smart people who know the hazards, and will train and adapt.
AHRI, ASHRAE, US DOE partnership devotes $5.2 million to broaden knowledge

The research program is part of an ongoing global effort to phase down the use of high-GWP refrigerants and identify appropriate climate-friendly alternatives. The DOE will contribute $3 million; ASHRAE, $1.2 million; and AHRI, $1 million.
Will facilitate and accelerate the safe use of these refrigerants
June 9, 2016
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI), ASHRAE, and the U.S. Department of Energy (DOE) are collaborating to fund research that will establish a more robust fact base about the properties and use of flammable refrigerants.
Topics include toxicity, flammability, and higher pressures

With the advancing worldwide phaseout of hydrochlorofluorocarbons (HCFCs), the United Nations Environmental Programme (UNEP’s) OzonAction Division of Technology has produced a series of factsheets on the safe use of the new alternative refrigerants.
Industry input is being sought into a proposal to modify portions of ASHRAE’s refrigeration safety standard to incorporate subclass 2L flammability classifications. Addendum d to ANSI/ASHRAE Standard 15-2013, Safety Standard for Refrigeration Systems, is open for public comment until Jan. 18.
Standard 15 specifies safe design, construction, installation, and operation of refrigeration systems

HVACR industry input is being sought into a proposal to modify portions of ASHRAE’s refrigeration safety standard to incorporate subclass 2L flammability classifications. Addendum d to ANSI/ASHRAE Standard 15-2013, Safety Standard for Refrigeration Systems, is open for public comment until Jan. 18, 2016.
Although it’s commonly acknowledged that there is no one-size-fits-all answer, natural refrigerants, such as carbon dioxide (R-744), ammonia (R-717), and the hydrocarbon (HC) refrigerants propane (R-290) and isobutane (R-600), have been garnering attention.
In March, the EPA approved several low-GWP hydrocarbon refrigerants for use in refrigeration and air conditioning applications, subject to use conditions. The approval drew a mixture of reactions ranging from support to concern.
