US retailer Piggly Wiggly has recorded energy savings averaging 28.5% over a seven-month period in a Georgia store, thanks mainly to its ammonia/CO2 refrigeration system.
French firm Atlantic Compressors is delivering an NH3-CO2 cascade system to serve the cooling needs of a distribution centre for one of France’s main supermarket chains. The system will be up and running next month.
Japan’s Mayekawa and North American companies CIMCO and SCE are collaborating to install and gather data on the performance of the NewTon refrigeration system in the United States.
While ammonia has long been an accepted industry standard refrigerant, especially in larger industrial refrigeration systems, a new generation of natural refrigerant technology is shaking up the sector. A special edition Accelerate Corporate, recently published in partnership with Japan-based Mayekawa, investigates further.
Japan-based technology provider Mayekawa Manufacturing Company, Ltd. has announced plans to launch four new models of its highly efficient natural refrigerant-based cooling system, the NewTon, on 21 July 2016. The NewTon R-3000 and R-6000 for cold storage, and F-300 and F-600 for frozen storage, will feature reduced refrigerant charge, system size and weight compared to previous models.
Emerson Climate Technologies is in the final stages of testing reciprocating compressors for CO2/ammonia cascade systems in its recently opened Helix Innovation Centre. The company expects to launch the new products in the coming months.
Mayekawa (MYCOM) turned heads at HVAC&R Japan 2016 in Tokyo with a prototype of a 30kW NH3/CO2 system for smaller industrial applications and potentially even commercial applications, while Danfoss showcased its broadest array of natural refrigerant solutions yet at the event.
Natural refrigerant systems are proliferating in Asian countries, offering environmentally friendly solutions while helping to reduce operating costs in a wide range of areas, from cold storage or ice rinks to ground freezing for construction work. Users of CO2/NH3 systems in Asia shared their experiences and plans for the future at ATMOsphere Asia 2016.
