New West Technologies announced that it has been chosen by the New York State Energy Research and Development Authority (NYSERDA) to develop a working prototype of an advanced energy storage and power system for refrigerated truck trailers that replaces their traditional diesel-powered systems.
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.
Coalition alleges dumping margins ranging from 100 percent to over 300 percent

The American Hydrofluorocarbon Coalition, a group of refrigerant suppliers, has filed an antidumping duty petition charging that unfairly traded imports of certain HFC blends and components from China are causing material injury to the U.S. domestic fluoro-chemicals industry.
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.
The plan that emerged from the Chemical Facility Safety and Security Working Group includes improved coordination and information sharing across DHS, OSHA, and the EPA as well as better coordination with state and local officials including the first-response community.
