First and foremost, I believe natural world, is the low-charge ammonia system that is just about refrigerant HVAC&R technology is the best replacement for installed on the rooftop of a 248,000-square-foot Baker Cold halocarbon refrigerant systems that harm the ozone layer and/or Storage warehouse in Long Beach, Calif. (page 42). This system, contribute significantly to global warming. which is being managed by another cold-storage operator, Lineage Logistics, comprises no less than 46 NXTCOLD low- But another very exciting aspect of this industry is the almost charge units, which will serve applications ranging from cold non-stop development of innovative natural refrigerant systems storage and blast freezers to railroad/truck docks and produce that are disrupting the marketplace and offering a myriad of new repacking. Rather than the 22,000 lbs. of ammonia originally options to end users. slated for this building, the system contains just 496 pounds for 1,015 TR. In this issue, we have several examples of eye-catching innovation. For example, our cover story (page 32) tells the story Also in this issue we have articles on two refrigeration systems of JTM Corp., a Piggly Wiggly franchise operator, that installed that have yet to hit the marketplace. What is particularly an ammonia/CO2 cascade refrigeration system in a store in notable about them is that they both depart from using vapor Columbus, Ga., last year – only the fourth supermarket in the U.S. compression in favor of a totally different technology. to implement such a system. It has a tremendous upside, saving the store on average 22% in energy over a four-month period this One of these systems, marketed by Cooltech Applications, year compared to an HFC system installed in the same building. employs the magneto-caloric effect, whereby certain materials The big question is whether the ammonia – just 53 pounds and heat up in a magnetic field, and cool off outside it page( 60). confined to the roof – will prove to be a safe and unobtrusive Based in France, Cooltech is starting to market the system in refrigerant over the long term; so far it has. the U.S. as a refrigeration option for beverage coolers. The other system, called IcePoint (from Rebound Technologies), uses Last month, another highly unusual system – a propane/CO2 ammonia to freeze water below its freezing point, and waste heat cascade system, at a store in Santa Clara, Calif. – was announced to separate the two and restart the cycle (page 10). by Whole Foods Market (page 10). Here, too, the high-side refrigerant, propane, is confined to the roof. This is believed to be How all of these innovative technologies are going to play out the first such installation in the U.S. remains to be seen. What is certain is they are challenging the status quo and offering end users new ways to run their businesses and help the environment.
