Many supermarkets converted their chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigeration systems to hydrofluorocarbon (HFC) systems only to see HFCs targeted for a phaseout. Now, they’re hearing about natural refrigerants, distributed refrigeration, and cascade systems.
There is always plenty of activity taking place on the HVACR side of the supermarket and restaurant industries. Here’s a quick look at eight items of note.
Florida Atlantic University’s (FAU’s) Institute for Sensing and Embedded Network Systems Engineering (I-SENSE) and Dioxide Materials™ have formed a partnership to develop and evaluate a novel low-cost, low-power, wireless CO2 sensing system for HVAC applications.
DeCicco & Sons’ newest store has been awarded Platinum GreenChill certification — the U.S. Environmental Protection Agency’s (EPA’s) highest sustainability award for food retailers — due to the grocer’s investment in a refrigeration system that uses natural refrigerant.
ATMOsphere America, a conference focusing on how natural refrigerants are being used in refrigeration, air conditioning, and heating systems, returns for its fifth edition, June 16 and 17, at the Westin Michigan Avenue in Chicago.
UK retailer Sainsbury’s has become the first customer to take delivery of Carrier Transicold’s prototype natural refrigerant trailer unit — a new generation of transport refrigeration system for trailers that operates exclusively with CO2 refrigerant.
As manufacturers research the viability of low-GWP and other natural refrigerants, they face the concurrent challenges of ensuring compressors are efficient, safe, and reliable.
The U.S. Army Natick Soldier Systems Center (NSSC) has awarded S-RAM Dynamics a Small Business Independent Research (SBIR) Phase 2 contract for $1 million to build and test a mobile refrigeration system demonstration prototype using the new S-RAM energy recovery compressor that utilizes CO2 refrigerant.
Hillphoenix has introduced its new AdvansorFlex CO2 refrigeration system, which the company said delivers all the benefits of CO2 refrigeration in a compact and scalable format for small and medium-sized retailers.
Honeywell Solstice ze (HFO 1234ze) refrigerant is being combined with carbon dioxide in a new supermarket cascade system designed to deliver heating, air conditioning, and refrigeration in one comprehensive, low-carbon solution.
