Program Scope
It is anticipated that course participants will become familiar with the ANSI/IIAR 4-2020 Standard for Minimum System Safety Requirements for the Installation of Closed-Circuit Ammonia Refrigeration Systems and be able to apply those requirements to a safely installed and operated refrigeration system.
Intended Audience
This course is intended to serve as continuing education for industrial refrigeration professionals whose job responsibilities include installation and safe operation of closed-circuit ammonia refrigeration systems. This audience would include plant managers, maintenance directors and supervisors, designers, engineering managers, facilities engineers, facility managers, service technicians, mechanical engineers, and refrigeration engineers, as well as employees who focus on regulatory requirements for ammonia refrigeration systems.
How It Works
The IIAR 4 Certificate course includes two training sessions, each approximately 60 minutes long, delivered as a PowerPoint presentation with lecture. At the end of each module, you must successfully complete a short quiz to check your comprehension of the material. To receive a certificate and continuing education credit, participants will be required to pass all quizzes as well as a final course examination, which is included in the course registration fee.
Final Exam
The final course examination will be administered online. Qualified registrants MUST have paid their Certificate Course tuition and MUST have successfully completed the Module 1 and 2 Quick Check Quizzes (at least 80% correct on both quizzes).
Course Requisites
We recommend these minimum requirements for individuals interested in participating in this program:
* General knowledge of the physical properties of ammonia
* Familiarity with design, operation, and maintenance of closed-circuit ammonia refrigeration systems
* Working knowledge regarding equipment that may be employed in operational closed-circuit ammonia refrigeration systems
Learning Objectives
After completing the IIAR 4 Certificate Course, learners will be able to:
· Explain the difference between normative and informative content in the IIAR 4 standard.
· Discuss general requirements for installation of an ammonia refrigeration system.
· List helpful installation documentation to request during procurement.
· Discuss general requirements for installation of an ammonia refrigeration system
· Discuss piping installation
· Discuss components and controls installation
· Identify considerations regarding insulation systems for ammonia refrigeration
Continuing Education Credits
After completing an IIAR Academy of Natural Refrigeration certificate course, successfully completing the accompanying quizzes, and passing the final course exam, you will earn the corresponding number of continuing education credits, which can be applied toward maintaining P.E. licensure. IIAR is accredited by the Registered Continuing Education Program for Engineers, Surveyors & A/E/C Professionals (RCEP) as an approved provider of continuing education.
The IIAR 4 certificate course offers 2.0 Professional Development Hours (PDHs) for learners who successfully complete the course.
Module 1
Background, References, and General Requirements for Installation
This module reviews the first half of the IIAR 4 standard. Content includes an examination of the standard's purpose, scope and applicability to safe installation of closed-circuit ammonia refrigeration systems, along with key definitions of terminology used in the standard. We’ll also address requirements for supervision of an installation, installer qualifications, contractor responsibilities, and safety training. IIAR 4 includes requirements for welding, suitable materials that can be used in the presence of ammonia, and allowable locations for components. The module wraps up with some non-mandatory recommendations for useful documentation that should be collected during the installation process.
Module 2
Installation of Piping/Controls/Insulation; Leak/Pressure Testing
The second module in the IIAR 4 certificate course looks at the second half of the IIAR 4 standard, including requirements for equipment installation and for installation of pipe, valves, and flanges. Module 2 also reviews installation of visual indicators and dives into both normative and informative specifications for installation of ammonia system insulation. We wind up with a list of recommended references that would be useful to consult before undertaking an ammonia refrigeration installation project.
