House of Spices (HOS) has ticked off a number of milestones in its 44-year history producing and distributing authentic Indian cuisine throughout the U.S. At its Chicago warehouse, the company recently achieved another rare feat, installing one of the few existing industrial CO2 transcritical refrigerant systems in North America, with the help of Hillphoenix.
In an exclusive interview published in Accelerate America issue #6, Joe Sanchez, application engineering manager at Bitzer, talks about the market opportunities for CO2 in North American supermarkets, food processing plants and ice rinks.
In light of ambitious greenhouse gas emission reduction targets in California, electricity supplier Southern California Edison (SCE) is making natural refrigerants central to its plans by evaluating the energy savings delivered by natural-refrigerant technologies. Through the state’s Refrigerant Management Plan, senior engineer at SCE Paul Delaney explains in the latest edition of Accelerate America how the utility plans to implement meaningful change.
At the upcoming ATMOsphere America 2015, Wieland Industrial Tubes will be participating for the first time as a Silver Sponsor, debuting its K65 high-pressure tube system for CO2 refrigeration systems. The K65 system is the only complete solution certified by TÜV based on a copper alloy.
At this year’s AHR Expo in Chicago, Emerson had their IPro Genius programmable controller on display. The IPro Genius controls high-pressure controls and bypass valves effectively to help maintain a constant flash tank pressure which is one of the keys to full efficiency when using a transcritical CO2 booster system and adds to the larger system to ensure optimal results for commercial refrigeration.
R744 technology innovator Systemes LMP has created a CO2 system for artificial cooling of ice slabs called the “CRYSTAL”, already installed at an ice arena in Canada. The CRYSTAL is a multi-compressor unit with an operating capacity of 30 to 140t ideal for new constructions of ice rinks under renovation. Thanks to its state-of-the-art design, the unit features total heat recovery of the compressors, which can be used for commercial space heating, hot water, mechanical room.
Hillphoneix, Carnot Refrigeration, Sanden, Bitzer US, KAV Consulting and Carter Synergy will be some of the companies presenting their latest CO2 based projects at the 4th edition of ATMOsphere America. These case studies will highlight innovation and efficiency in commercial and industrial refrigeration applications, heat pumps and data centers.
On April 21 a Kroger store in Ohio, U.S. became one of only a handful of stores to receive the GreenChill Partnership Platinum level award from the Environmental Protection Agency (EPA). The installed refrigeration system is a Hillphoenix CO2 transcritical solution that is expected to reduce the store’s overall carbon footprint by 40%.
In addition to featuring a number of low-charge ammonia products, the IARW-WFLO Convention & Expo, held in Orlando, Florida on 26 – 19 April, included several exhibitors promoting CO2-only and ammonia/CO2 refrigeration systems. While CO2 is still relatively new for the refrigerated warehouse operators attending the show, it is slowly gaining traction as an alternative to traditional high-charge ammonia systems.
A new flagship market in downtown Boston will keep its seafood fresh with a Howe flake ice machine using CO2 as a natural refrigerant.
