R744.com: ATMO America: Study Shows Efficiency Impacts of Transcritical CO2 Add-on Technologies in High Ambient Climates

U.S. component manufacturer Emerson and South African consultant Future Green Now have partnered on a new study designed to help supermarkets in North America identify which add-on technologies they should use to boost the efficiency of transcritical CO2 (R744) refrigeration systems in warm climates.

The study – “New to the World Climate Study for the Americas: Climate Zone Impact of CO2 System Selection” – looks at the amount of time CO2 systems spend operating in less-efficient “transcritical mode” in 166 cities across 13 climate zones in the Americas. It then examines how this time could be reduced by adding an adiabatic gas cooler, parallel compression, ejector, or some combination of these technologies to the system.

Findings from the study were presented by Andre Patenaude, Director Solutions Strategy – Cold Chain at Emerson Commercial and Residential Solutions, and Samantha Bothma, Design Engineering Consultant at Future Green Now, during a refrigeration case study session at the ATMOsphere (ATMO) America Summit 2022 on natural refrigerants. The conference took place June 7–8 in Alexandria, Virginia, and was organized by ATMOsphere, publisher of R744.com.
