Introduction to Ammonia Refrigeration Operation: The objective of this 16-hour Introductory to Ammonia Refrigeration course is to offer a fundamental approach to ammonia refrigeration systems, devices and theory, including introductory operation & important refrigerant safety practices. The course is a great overview for new refrigeration operators to bridge the understanding gap from HVAC-R to industrial ammonia refrigeration or beginning fundamental refrigeration applications. Students receive instruction of fundamental applications at a pace geared for a true understanding of the ammonia systems. Students can expect an introduction approach in areas of maintenance scheduling/planning, servicing, system diagnostics, troubleshooting, and fine-tuning to gain maximum efficiency of an ammonia system. The course also covers an introduction to regulatory compliance such as Process Safety Management- Risk Management Programs (PSM/RMP) and system requirements and personal protective equipment.
Ammonia Refrigeration Operator I: Topics of discussion will include, but not be limited to: Refrigeration theory – how the refrigeration process works; Refrigeration systems –concentration on the vapor compression system; Refrigerants properties – specifically ammonia with emphasis on safety; Evaporators – operations and maintenance; Compressors – operations and maintenance; Condensers – operations and maintenance; Piping systems – understanding of piping practices and piping maintenance; Low temperature refrigeration – dealing with two stage systems; and Controls – how electrical and mechanical systems function together. Instruction is designed to incorporate the individual’s system design to familiarize each participant with how the system meets the facility demands. PSM and RMP will be emphasized where applicable.
