Detailed methods for calculating pressure drops and velocity to prevent erosion and noise.

Those who have purchased the official printed copy can access additional resources, downloads, and updates directly through the IIAR Publication Resources page.

Ammonia systems experience extreme temperature swings, causing pipes to expand and contract. The text outlines how to design expansion loops, select pipe hangers, and place anchors to prevent structural fatigue and weld failures. 5.

Guidance on selecting and installing hand stop valves, solenoid valves, pressure regulators, and check valves. Detailed methods for calculating pressure drops and velocity

Discharge lines carry high-pressure, superheated ammonia gas from the compressor to the condenser. The handbook details how to design these lines to handle thermal expansion, minimize vibration from compressor pulses, and prevent oil trapping. 5. Liquid Lines

If you are a student in a mechanical engineering or HVAC-R program, check your library’s database. Some institutions purchase access to engineering standards via Techstreet or IHS Markit, which resell IIAR documents. The text outlines how to design expansion loops,

The handbook provides comprehensive technical guidance across several critical areas of closed-circuit ammonia refrigeration systems:

Standards for preventing moisture ingress, managing thermal efficiency, and mitigating Corrosion Under Insulation (CUI).

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

Approved specifications for carbon steel and stainless steel piping, fittings, and copper-free valves compatible with anhydrous ammonia.
