Refrigeration Learning System

Learn the thermodynamics fundamentals and main components of refrigeration cycle basics in a compact workstation

This system is designed to teach the fundamentals of refrigeration to students starting their learning in HVAC/R. With a data acquisition interface (DAI), parameters are shown live, making abstract notions such as enthalpy or COP much easier to grasp. A refrigeration training unit is often a “magic” piece of equipment that generates cold for the non-specialists. The Refrigeration Learning System (DAI) includes a software that shows the components of the system along with pressure and temperature readings at key locations.

Topic coverage

  • Identify the main components of a typical refrigeration cycle and briefly explain their role
  • Verify the pressure-temperature relationship of R-134a using the DAI, determine the COP and NRE
  • Describe and configure the pressure and temperature controllers
  • Vary the load, fan speed or expansion device and observe the effect on the other parameters of the system using the software
  • Perform various electrical measurements and troubleshoot faults
