Refrigeration Cycle Teaching System

Bench-top apparatus that demonstrates the refrigeration cycle.

This simple refrigeration cycle unit assists students to learn the stages of refrigeration at an entry level. Students learn about Pressure-Enthalpy charts and use them to determine the Coefficient of Performance (COP), superheat and sub-cooling from the enthalpy changes.

Key features

  • Includes TecQuipment’s Versatile Data Acquisition
    System VDAS® Onboard, featuring data acquisition via USB
  • VDAS® software allows students to visualize experimental parameters using pressure–enthalply charts
  • Pressure andTemperature sensors in heat source and heat-sink water tanks allows clear demonstration of a refrigeration or heat pump cycle
  • Water pump allows circulation of water for steady-state experiment
