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.

The refrigeration circuit features high and low pressure gauges, a pressure switch, sight glass, filter dryer and TEV valve. The circuit also includes pressure transducers that connect to the instrumentation.

The evaporator and condenser coils are submerged in heat source and heat sink water tanks for the clear demonstration of a practical heat pump. A small pump provides a circulation of the water between the heat source and sink for steady state experiments.

  • Learn to use a P-h Chart
  • Determine Coefficient of Performance (COP)
  • Determine superheat and sub-cooling
  • Basic refrigeration cycle energy balance
  • Determine isentropic and non-isentropic efficiencies of the compression stage
  • Effect of heat source and heat sink temperatures on COP
Case Study
Nottingham Trent University Video Case Study

In October 2019, Nottingham Trent University opened a new engineering teaching and research facility, that houses a wide range of apparatus from TecQuipment for bringing mechanical theory to life. In this video case study, lecturers and laboratory technicians talk about how they use these products to teach engineering principles that relate to fluid dynamics, heat transfer, thermodynamics, materials testing, and engineering science and all levels of engineering study at degree level.
