Industrial/Commercial Air Certificate (IA21)  Technical Certificate of Credit

Introduces the basic concepts, theories, and safety regulations and procedures of refrigeration. Topics include an introduction to OSHA, safety, first aid, laws of thermodynamics, pressure and temperature relationships, heat transfer, the refrigerant cycle, refrigerant identification, and types of AC systems.

This course provides an introduction to fundamental electrical concepts and theories as applied to the air conditioning industry. Topics include AC and DC theory, electric meters, electrical diagrams, distribution systems, electrical panels, voltage circuits, code requirements, and safety.

This course is designed to provide the Industrial Refrigeration Operator with a more in-depth understanding of the theory and practical knowledge required to success fully operate today's more sophisticated and demanding systems. The course consists of two parts. Participants will spend approximately equal time in the classroom and in the hands-on lab.

This advanced course is designed to provide students with sufficient knowledge and practical skill in all areas of industrial refrigeration operation. Topics include blueprint and diagram reading and interpretation, design codes and standards, piping, load calculations, freezer design and operation, compressor operations, and advanced evaporator and condenser topics.

This course introduces the operational theory, systems terminology, PLC installation, and programming procedures for Programmable Logic Controllers. Emphasis is placed on PLC programming, connections, installation, and start-up procedures. Other topics include timers and counters, relay logic instructions, and hardware and software applications.

This course provides for hands on development of operational skills in the maintenance and troubleshooting of industrial control systems and automated equipment. Topics include data manipulation, math instructions, introduction to HMI, analog control, and troubleshooting discrete IO devices.

Provides an increased level of concepts and theory beyond AIRC 1020. Students are introduced to more design theory in commercial refrigeration. Topics include: refrigeration heat calculation, equipment selection, refrigeration piping, codes, and safety.
