Startup of Closed-Circuit Ammonia Refrigeration Systems
ANSI/IIAR 5 will define the minimum requirements for startup of closed-circuit ammonia refrigeration systems. The standard will be known as the first of its kind supporting the Initial Startup Procedure defined by OSHA’s PSM and EPA’s RMP requirements. It presupposes that the persons who use the document have a working knowledge of the functionality of an ammonia refrigeration system(s) and basic ammonia refrigeration practices and principles. This standard is intended for those who startup closed-circuit ammonia refrigeration systems. This standard shall apply only to stationary closed-circuit refrigeration systems utilizing ammonia 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 (e.g., model mechanical or fire codes).
The proposed standard under review/comment is proposed as a 7 chapter text and three of which will be core topics.
- Pre-Charging Activities and Requirements
- Startup Process
We encourage you to review and comment as needed on the new proposed standard.
