T/CNFAGS 11-2024 Technical specifications for ammonia refrigerating(centrifugal compressor) system
Basic Information
Scope
This document defines the terms of ammonia refrigeration systems and stipulates the requirements for ammonia refrigeration systems and their centrifugal compressors, dry gas seals, control valves, containers, heat exchangers, overpressure relief devices, pumps, piping and equipment layouts, instrumentation and control systems, and electrical systems.
This document is applicable to refrigeration systems using ammonia as the refrigerant, with a design temperature not lower than -50 ℃, and centrifugal compressors. Centrifugal refrigeration systems using other refrigerants can be implemented with reference to this document.
This document does not include the requirements for the driving equipment of ammonia refrigeration systems (such as motors, steam turbines), gearboxes, couplings, and lubrication (regulation) oil systems.
