Transcritical CO2 Refrigeration is Applied to the Cold Storage Industry

Arlington, VA (October 29, 2019)

     The World Food Logistics Organization (WFLO), a Core Partner of the Global Cold Chain Alliance (GCCA) is pleased to announce the publication of a new cold chain industry white paper developed by the GCCA Refrigeration & Energy Committee on the use of transcritical CO 2 (TCO) refrigerant in the refrigerated warehouse industry.

With increased regulatory attention on ammonia and the long-term uncertainties with some of the synthetic refrigerants, it is important for cold chain logistics providers to understand the evolution of CO 2 refrigeration technologies as they evaluate which refrigerants and systems are most effective for their situation.  All of these refrigerants can be viable choices depending on their application.  This white paper includes background and case studies that can provide members with useful information as they consider future refrigerant choices.

“The case studies presented in this paper clearly illustrate that an effective metric to use when comparing transcritical CO2 systems to traditional refrigeration systems is the Total Cost of Ownership (TCO) metric,” says Eric Teale, PE, CRST, Business Development Manager – Industrial Refrigeration for Danfoss. “When TCO is used, the relatively minor inefficiencies of a transcritical CO2 system are offset by larger factors that provide a lower TCO as compared to traditional refrigeration systems. Transcritical CO2 systems are a viable alternative to traditional refrigeration systems.”

The use of TCO is significant in the refrigerated warehouse industry. Paul Henningsen, President, Henningsen Cold Storage Co., has this to say: “We place a great emphasis not only on the safety of our associates, the environment, and the products we are entrusted with by our customers, but also on energy efficiency, continuous improvement, regulatory compliance, and sustainability. Trans-critical carbon dioxide refrigeration has been a great solution to meet all of our objectives, including the added benefit of a reduced construction schedule and lower construction costs.”

The complimentary white paper may be downloaded from the GCCA website.
