California natural refrigerants

California utility sees big potential for natural refrigerants

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.

IPro Genius is the cherry on top of Emerson’s CO2 booster system

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.

Systemes LMP installs CRYSTAL CO2 unit at Canadian ice arena

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.

IARW exhibitors see interest in transcritical CO2 and NH3/CO2 in cold storage sector

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.
