The IIAR (International Institute of Ammonia Refrigeration) has been marketing the industrial natural refrigerant market for the last few years. From there national conference to publications the institute is emerging advancements outside of just ammonia refrigeration. IIAR is working on releasing a new standard for CO2 Refrigeration systems will be the first of its kind. This new proposed standard is out for public review. We encourage you to download and give your CO2 feedback to help make it the best safety and design standard on the market.
The new CO2 Standard will specify the minimum requirements for safe design, safe installation, start-up, and inspection, testing, and maintenance (ITM) tasks applicable to stationary closed-circuit carbon dioxide refrigeration systems. It presupposes that the persons who use the document have a working knowledge of the functionality of carbon dioxide refrigeration system(s) and basic carbon dioxide refrigeration practices and principles. This standard is intended for those who design, install, start-up, and inspect, test, and maintain stationary closed-circuit carbon dioxide refrigeration systems. This standard shall apply only to stationary closed-circuit refrigeration systems utilizing carbon dioxide as the refrigerant. It supplements existing general refrigeration standards issued by IIAR and other organizations such as ASHRAE, ASME, and ANSI. It is not intended to supplant existing safety codes.
