Efficiency – Properly sized piping reduces pressure drop, lowering compressor energy costs by 5–15%. The handbook gives you the formulas and friction loss data to optimize your system.
What is the IIAR?
Before diving into the Piping Handbook, it is crucial to understand the authority behind it. The International Institute of Ammonia Refrigeration (IIAR) is a non-profit trade association dedicated to the safe use of ammonia as a refrigerant. Their standards (e.g., IIAR 2, IIAR 3, IIAR 4, and IIAR 5) are recognized globally by OSHA (Occupational Safety and Health Administration) and building codes as the benchmark for safe system design.
