Emerson Climate Technologies Inc. will host a webinar, “Seven Keys to Servicing CO2 Systems,” to explore the many operating implications of a CO2 (R-744)-based refrigeration system. The complimentary webinar will be held Tuesday, July 14, from 2 to 3 p.m. EDT.
This case study documents one year of operating experience with a transcritical carbon dioxide (TC CO2) booster refrigeration system at Delhaize America’s Hannaford supermarket location in Turner, Maine. This store, which began operation in June 2013, is the first supermarket installation in the U.S. of a TC CO2 booster refrigeration system.
Everyone talks about what it initially costs a supermarket to switch to a 100 percent CO2 commercial refrigeration system. But start thinking about the costs that come next — on everything from electricity to regulatory compliance — and the return on investment on CO2 begins to make a great deal of sense.
So, supermarket owners want refrigeration systems that are energy efficient to hold down costs and pro-environmental for political correctness. But for engineers, contractors, and technicians that approach may not be all that easy, whether bringing a new store online or retrofitting an existing one.

The International Institute of Refrigeration (IIR) announced the first edition of the IIR guide “CO2 as a Refrigerant,” written by Dr. A.B. Pearson, an expert in the field of CO2 application. The organization said the guide highlights the use of CO2 in various sectors.
As 2015 begins, the end of new and imported HCFCs is in sight and phasedown and limits on certain HFCs seem more and more likely. So to continue to meet refrigeration needs, f-gas proponents turn to low global warming potential (GWP) HFCs and HFOs, while advocates of natural refrigerants continue to build their case.
