If hydrofluorocarbons (HFCs) are to have long-term viability, the low-global warming potential (GWP) versions will have to separate themselves from high-GWP types. And the survivors will have to play their part in energy efficiencies, especially in commercial buildings.

CO2 as a refrigerant has been a part of the refrigeration landscape for close to a decade. The most anticipated next step was running CO2 as a standalone refrigerant in a system, which is being done in Europe in more and larger applications. Finally, the approach crossed the Atlantic.

This article is the second of a two-part series in response to the question: “Should I choose CO2 (R-744) for my refrigeration system?” It was prepared by engineers with M&M Refrigeration of Federalsburg, Maryland.

This story was prepared by Danfoss and brings readers up to date on developments in Europe concerning HFC refrigerants. While what happens in Europe does not automatically reflect what will happen stateside, it would be wise for contractors in the United States and Canada to monitor developments overseas.

The 2014 ASHRAE Handbook—Refrigeration, which covers refrigeration equipment and systems for applications other than human comfort, is now available for purchase. The 51 chapters include information on cooling, freezing, and storing food; industrial applications of refrigeration; and low-temperature refrigeration.

The annual Food Marketing Institute Energy & Store Development Conference takes place Sept. 7-10 at the Union Station Hotel in downtown St. Louis. The focus of the annual event is on energy efficiency and conservation as well as store design and merchandising.

When I think of how big and complex our industry is, I see it most reflected in the limited number of places the refrigeration shows I have attended can be held. These shows have a lot of people looking at a lot of products.

Emerson Climate Technologies announced that it is preparing an industry communication to the U.S. Environmental Protection Agency’s (EPA’s) recent notice of proposed rulemaking (NOPR) that would delist some refrigerants commonly used in supermarkets and commercial refrigeration equipment.

Martin C. Eldridge III now faces 31 months in federal prison for releasing the refrigerant, which is currently being phased out of production in the U.S. due to its threat to the earth’s ozone layer.

Here, manufacturers of large machinery bring some of their latest developments, along with the range of products and services on display every year.
