Under a settlement with the U.S. Environmental Protection Agency (EPA), Bozzuto’s Inc., which operates a cold storage warehouse in North Haven, Connecticut, is updating its operations so that public safety is enhanced. The company has also agreed to pay $124,181 to settle claims it violated the federal Clean Air Act.

HFO refrigerants are actually unsaturated HFC refrigerants and are widely recognized as the next generation of refrigerants because of their environmental friendliness, cost-effectiveness, and great energy efficiencies.

A common accessory used on many refrigeration systems is the liquid receiver, a storage vessel designed to hold excess refrigerant not in circulation.

To continue to meet refrigeration needs, f-gas proponents are turning to low-global warming potential (GWP) HFCs and hydrofluoroolefins (HFOs) while advocates of so-called natural solutions — hydrocarbons (HCs), CO2, and ammonia — continue to build their cases.

Rajecki will replace current refrigeration editor Peter Powell, who will be retiring in February 2015.

The announcement a few months ago that the U.S. Environmental Protection Agency (EPA) was proposing to decertify certain high-global warming potential (GWP) HFC refrigerants for use in a wide range of new commercial refrigeration equipment did not come as a surprise to the HVACR industry.

With the phaseout of R-22, many food retailers are adapting to future R-22 supply constraints by transitioning away from this refrigerant. Because many of the substitute refrigerants are potent greenhouse gases, it is important that food retailers use the retrofitting process as an opportunity to tighten system leaks.

The following article was prepared by Parker Hannifin Corp. Micro Thermo Technologies and describes one of the approaches for use of CO2 in transcritical systems for refrigeration.

Polar Technology has announced that the California supermarket chain Stater Bros. is implementing a cloud-based refrigerant management program called TrakRef.
