DSS Energy Efficiency: Refrigeration

DSS Energy Efficiency: Refrigeration is part 15 of the DSS Energy Efficiency 16-part training series featuring DSS owner-operator content.

The course covers the components and principles of refrigeration systems and their efficient use.

Course objectives include:

  • Exercise proper safety precautions when working with and around refrigeration systems
  • Identify the parts that all mechanical refrigeration systems have in common
  • Assess the relationship between pressure, temperature, evaporation, and condensation in a refrigeration system
  • Compare common refrigerants
  • Apply the principles of operation of positive displacement and centrifugal refrigeration systems
  • Apply specific best practices for energy efficiency to refrigeration systems.
