An industrial ammonia refrigeration system relies heavily on safe, efficient, and compliant piping design. The International Institute of Ammonia Refrigeration (IIAR) publishes the , which serves as the global benchmark for engineers, contractors, and operators.
Detailed methods for calculating vapor and liquid flow capacities, estimating pressure losses, and selecting valves.
The complete handbook also includes chapters on plant layout, machinery room design, welding requirements, system schematics, relief piping, and insulation systems. iiar ammonia refrigeration piping handbook pdf link
Hydraulic shock, or "liquid hammer," occurs when a slug of liquid ammonia travels at high speed through a pipe and hits a sudden restriction, such as a closed valve or an elbow. This phenomenon can rupture steel pipes instantly. The handbook provides specific piping geometries and valve timing recommendations to eliminate hydraulic shock risks. Oil Management
