Three Key Takeaways from the IIAR 2018 Natural Refrigeration Conference & Expo

Recently, Hixson’s Jim Adler, P.E., attended the 2018 International Institute of Ammonia Refrigeration (IIAR) Natural Refrigeration Annual Conference and Expo in Colorado. Jim, who is the Manager of Hixson’s Refrigeration department and a former IIAR board member, noted that one of his biggest takeaways from his time at the event, which marked its 40th year in 2018, concerned the refrigeration codes.  “IIAR is in the process of issuing an addendum to IIAR-2, the American National Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems, to correct known issues and include adsorption systems,” said Jim.  “This will allow ASHRAE-15 to revise their ammonia design requirements and refer to IIAR-2, and will help in project work by only needing to reference one code for design.”

In addition to general information sessions, technical papers were also presented at the conference, including one which covered the use of a packaged CO2/NH3 system for a supermarket.  According to Jim, the paper’s authors concluded that the technology was proven viable, and also resulted in reduced operating costs.  “This could lead to larger systems for industrial users,” said Jim.

Finally, Jim provided an overview of several standards that are in or soon will be entering into, the public review phase.  “The Recognized And Generally Accepted Good Engineering Practices (RAGAGEP) standard, of which I am a member of the team helping to write, has had its first public review, generating more than 200 comments,” said Jim.  In addition, the Process Safety Management/Risk Management Plan (PSM/RMP) program, Ammonia Refrigeration Management (ARM) programs, and the low-charge ARM program are all very close to being issued for public review.
