The piping handbook works in tandem with several ANSI/IIAR standards that you should be aware of:

The IIAR is the only organization writing performance and design standards specifically for ammonia refrigeration systems, making its publications fundamental to the industry. The Piping Handbook serves as a guidance document, providing recommendations on industry best practices rather than mandatory, code-enforceable rules.

Active members frequently receive discounted pricing or bundled digital access to the entire library of standards, handbooks, and data books.

These tables are vital for designing vapor and liquid systems, including flooded evaporators and pumped overfeed risers. iiar ammonia refrigeration piping handbook pdf link

Ammonia and traditional refrigeration oils do not mix easily. Oil tends to settle at the bottom of vessels and pipes, acting as an insulator and reducing heat transfer. The handbook teaches designers how to pitch pipes correctly and use oil separators effectively to keep the system running cleanly.

Using an official copy of the handbook ensures your facility stays compliant with OSHA and EPA regulations in the United States. Key safety topics included in the PDF version often include:

Serves as a recognized and generally accepted good engineering practice (RAGAGEP) for compliance.
