Danfoss launches latest Application Development Center in Florida
August 2, 2017
Danfoss’ latest “Engineering Tomorrow” Application Development Center in Tallahassee, Florida, will be able to test mildly flammable refrigerants at global nameplate voltages, with real-time data acquisition and performance.
Residential and commercial ‘worst-case scenarios’ included in A2L research
July 5, 2017
The Air-Conditioning, Heating, and Refrigeration Technology Institute (AHRTI) — the research arm of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) — released the first research report as part of its ongoing testing of flammable refrigerants, many of which were identified as possible replacements to high-GWP (global warming-potential) hydrofluorocarbons (HFCs) that will be phased down under the Montreal Protocol.
Researchers must look beyond nonflammable chemicals
April 3, 2017
NIST’s study, entitled “Limited options for low-global warming potential [GWP] refrigerants,” focused on residential and small-commercial single-package and split air conditioning systems, but the authors said their conclusions also generally apply to room air conditioning units and other refrigeration and heat-pump systems currently using common, ozone-depleting refrigerants such as R-410A or R-22, which are still used in some developing countries today. “The takeaway is there is no perfect, easy replacement for current refrigerants,” NIST chemical engineer Mark McLinden said.
Incorporating flammable refrigerants into manufacturing processes can have a dramatic impact on your facility from testing procedures to reclassification as a hazardous location to modifying or building new labs.
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
June 20, 2016
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
February 1, 2016
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.
