HFC emissions in the US are expected to nearly double by 2020 and triple by 2030

EPA estimates this final rule will reduce greenhouse gas emissions of 54-64 million metric tons of carbon dioxide equivalent in 2025, equal to the carbon dioxide emissions from the annual energy use of more than 5.8 million homes.
The HFC management workshop and Open-Ended Working Group meetings are an opportunity to present technical information relevant to HFCs, such as high-ambient temperature performance, safety requirements, and energy efficiency, and to provide a forum to discuss potential obstacles to an HFC phasedown.
Honeywell Intl. Inc. announced that leading global compressor manufacturers Emerson Climate Technologies Inc., Bitzer, and Frascold have approved Honeywell’s low-global warming potential (low-GWP) refrigerants Solstice N40 (R-448A) and Solstice N13 (R-450A) for use in their commercial refrigeration compressors.
As expected, R-404A, -407A, -410A, -507A, many others targeted

On July 2, the U.S. Environmental Protection Agency (EPA) issued its Final Rule — Protection of Stratospheric Ozone: Change of Listing Status for Certain Substitutes under the Significant New Alternatives Policy Program.
If refrigerant migration occurs in a system that has a crankcase heater, the vapor will be forced away from the crankcase and end up in the suction line. This refrigerant may condense in the suction line and cause slugging in the compressor’s cylinders on startup.
Thinking in temperature in-stead of pressure can help make the crossover to a new refrigerant much easier. The next time you’re faced with determining the correct operating evaporator or condensing pressure, think in terms of temperature and then convert it to pressure.
