Refrigeration System Demonstrator

The Refrigeration System Demonstrator (3400-3) is an integrated training system for instructor demonstration and hands-on student experimentation in the fundamental principles and components of typical refrigeration systems and heat pumps. The demonstrator is designed to clearly show the different refrigerant stages within the cycles of the most common refrigeration system configurations. The Refrigeration System Demonstrator includes all the equipment required to perform the exercises contained in the courseware. Available optional equipment adds to the efficiency of the refrigeration, air conditioning, and heating training exercises.

The training system is supported by correlated courseware employing a competency-based, individualized approach to the study of refrigeration fundamentals. The courseware consists of a training manual organized in a unit/exercise format with clearly stated objectives, and a companion instructor’s lesson planning guide.
