PHOENIX — The International Institute of Ammonia Refrigeration (IIAR) welcomed more than 1,600 attendees and 150 exhibitors to its annual Natural Refrigeration Conference and Expo. The three-day event provided extensive opportunities to learn more about how natural refrigerants such as ammonia, CO2, and hydrocarbons are being used in refrigeration applications.
This year’s conference was a little different, as IIAR partnered with the North American Sustainable Refrigeration Council (NASRC) to offer a dual track of technical papers, panels, and workshops. The Commercial and Food Retail Refrigeration track featured presentations on topics ranging from low-charge ammonia systems in grocery stores to the first and only propane/CO2 cascade system in a North American supermarket.
