Yamato Co. Ltd., a Japanese engineering company specialising in the planning, design and installation of HVAC&R facilities, has developed and tested a new CO2-based brine-ice thermal storage system.
A paper published in the January 2017 edition of Applied Thermal Engineering compares CO2 transcritical systems to HFC systems in Sweden.
A new energy efficiency network within the global retail giant Metro Group is translating into a strong commitment to natural refrigerants.
A CO2 transcritical booster system is helping to deliver energy savings at a Co-op supermarket in the northern English town of Horwich, near Manchester.
Major food retailers like Piggly Wiggly, Sobeys and Roundy’s are harnessing natural refrigerant technologies to deliver energy savings at stores across North America, heard participants in the ATMOsphere America conference in Chicago earlier this month.
Hillphoenix has already installed its recently introduced AdvansorFlex CO2 transcritical unit – a downsized, less expensive version of its traditional Advansor CO2 transcritical booster system – in 30-40 stores in the United States, Derek Gosselin, the Conyers, Ga.-based company’s systems technical sales manager, told R744.com at the Food Marketing Institute Connect show at McCormick Place in Chicago yesterday (22 June).
Epta Refrigeration has installed a new commercial refrigeration system at a Walmart store in Buenos Aires. The supermarket giant hopes that the technology, which uses CO2 as the refrigerant, will reduce the store’s annual energy bills by 21%.
As retailers seek to enhance their commitment to sustainability, a concern often raised is cost. Although replacing a traditional HFC based system with a 100% CO2 system is more environmentally friendly, the initial cost for CO2 refrigeration equipment is generally higher. However, as system manufacturer Hillphoenix explains in their White Paper “DeCO2ded: understanding ROI on CO2 refrigeration systems”, CO2 offers a positive ret
