Series I Basic Ammonia Refrigeration Training ProgramAvailable in Spanish

The IIAR Basic Ammonia Refrigeration training program is a complete package of online instructional Videos and Tests to document employee training. Each module takes a step-by-step approach to fundamental ammonia refrigeration principles, applications, and components. These videos are designed to be used by companies for in-house training.

  • Introduction to Ammonia Refrigeration – This module examines applications of ammonia in the refrigeration industry. It reviews the molecular structure and basic chemical properties of ammonia, including an explanation of change of state and heat transfer process. In addition, this module explores the relationship between temperature and pressure.
  • Ammonia Refrigeration Systems – This module examines the major components that make up ammonia refrigeration systems, including direct expansion, recirculating, and indirect systems. This module also explores the role of pressure reduction devices in the system.
  • Evaporators – This module explores the inner workings of air units and liquid chillers, including shell & tube and plate & frame evaporators. It examines evaporator capacity and factors that impact evaporator operation. It also explores the pressure of the ammonia as it flows through the evaporator and the temperature difference between the liquid ammonia and the air, or secondary coolant, being cooled.
  • Compressors – This Module examines the operation of compressors commonly used in the ammonia refrigeration industry: the reciprocating compressor, the rotary vane compressor and the screw compressor. This module also discusses volumetric efficiency, swept volume and compression ratio.
  • Condensers – This Module explores air-cooled condensers, water-cooled condensers and evaporative condensers. It also outlines the factors that may impact a condenser’s efficiency and heat-transfer capability including the surface are of the heat transfer material, the conductive capability of the heat transfer surface, the difference in temperature between the cooling agent and the ammonia vapor and the rate and direction of flow of both the ammonia and cooling agent.
  • Shut-Off Valves – This module focuses on the use of shut-off valves in the ammonia refrigeration system. It describes various types of shut-off valves commonly in use. It also identifies the parts of a standard shut-off valve, provides installation guidance, including valve orientation and outlines standard maintenance procedures.
  • Control Valves – This module focuses on the characteristics of control valves in ammonia refrigeration systems. The video focuses primarily on solenoid valves and pressure regulators. It also identifies the principles of operation of direct and pilot operated control valves. Finally, it examines the various types of control valves that are commonly employed as well as their components.
  • Pumps – This module explores how pumps are used to move ammonia through a refrigeration system. It explores positive displacement and centrifugal pumps, pump components, problems associated with pumps including cavitation and the role of pumps in a liquid recirculation refrigeration system.

Series II - The IIAR Ammonia Refrigeration Safety Training Program
Each module focuses on critical safety information including the potential hazards of ammonia, personal protective equipment, emergency response team structure and emergency response procedures. Employee safety and efficient operation of your ammonia refrigeration system are fundamental to your company’s success. The IIAR Ammonia Refrigeration Safety Training Videos are excellent teaching tools for facility management, operations and maintenance personnel and any other employee who is expected to manage an emergency response or perform specific duties in the event of an ammonia release.

  • Introduction to Personal Protective Equipment – This module focuses on the nature of ammonia and its safe use as a refrigerant. It examines the characteristics of the three states of ammonia release: vapor, liquid and aerosol. Module 1 also discusses exposure levels, hazards and personal protection equipment.
  • Use of Personal Protective Equipment – Module 2 reviews basic personal protective equipment, it uses and its limitations. It provides a detailed description of the two main types of respirators and the varying levels of protection each offers. This module also discusses the four levels of personal protective equipment as defined by OSHA in the United States
  • Emergency Response – This module focuses on emergency action plans and the emergency response plan regulations, procedures and strategies for ammonia refrigeration facilities. It discusses the various levels of training required and outlines the actions that may or may not be taken by appropriately trained individuals.
  • Emergency Response Procedures – This module focuses on emergency response procedures. It covers preplanning and preparation for an emergency response, entry and decontamination procedures, first aid and post emergency evaluation.
  • The First 30 Minutes – This Module focuses on the first 30 minutes of an ammonia release or accident. It provides detailed instruction on how to plan and execute appropriate procedures for initial response. From plant technicians to fire officials, this module discusses the tool you need in order to quickly, efficiently, and effectively respond to an ammonia release or accident within the first 30 minutes.
Series III - Removing Oil from an Ammonia Refrigeration System - Available in Spanish

This training program instructs system operators in the most important maintenance procedure routinely performed – the safe draining of oil since this process is also the most common, it is imperative that system operators are properly trained with up to date oil draining guidelines.

All online videos include online exams to document successful completion of each course module. Student hours of completion are recorded by IIAR on the Learning Management System (LMS) with Personal Development Hours (PDH) certificates provided upon completion of the project.
