CO2 condensing units boost efficiency up to 27%, R290 units up to 30%, according to case studies in new EIA/shecco study, unveiled at ATMOshere Europe 2018.
Supermarket refrigeration systems using CO2 or propane (R290) were found to be more efficient than their HFC counterparts, according to a new report published by the Environmental Investigation Agency (EIA) and shecco, publisher of this website.
The report “ Technical report on energy efficiency in HFC-free supermarket refrigeration ” was released this week at ATMOsphere Europe 2018 , in Lago di Garda, Italy, where a session presented the main highlights of the report.
The EIA/shecco initiative was funded by the Kigali Cooling Efficiency Program (KCEP) to support the consideration of energy efficiency requirements by members of the Consumer Goods Forum (CGF) as they roll out HFC-free commercial refrigeration.
“The report itself aims to serve as an information source for end users looking for energy efficient HFC-free alternatives,” said Klára Zolcer Skačanová, Market Development Manager, shecco.

According to the report, various energy-efficient HFC-free commercial refrigeration options currently exist for different sizes of supermarkets:
Switching refrigeration systems away from HFCs offers an ideal opportunity for supermarkets to simultaneously improve their energy efficiency. Through careful planning and assessment of future-proof decisions, supermarkets can now be designed and installed with both the climate and the bottom line in mind.
“Food retailers should use the opportunity of the HFC phase-down to simultaneously improve the energy efficiency and sustainability of their refrigeration systems,” said Clare Perry, Climate Campaign Leader, EIA.

Food retailers will be key players in ensuring market demand for energy efficient HFC-free technology, encouraging development of new technology and system controls, providing and sharing case studies and success stories and maintaining pressure on the manufacturing industry and policymakers to ensure the success of the HFC phasedown.
Decisions concerning refrigeration systems must take into account the total life cycle cost (not just the initial upfront cost) and the full environmental impact. Making the right choice of refrigerant and system now will avoid serious headaches for retailers down the line.
