Refrigeration System Demonstrator

The Refrigeration System Demonstrator 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. It is designed to clearly show the different refrigerant stages within the cycles of the most common refrigeration system configurations.

The training system is supported by correlated courseware employing a competency-based, individualized approach to the study of refrigeration fundamentals.
