Technical Specification
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.
  • Single phase, 220 - 240 VAC, 50 Hz
  • PC running Windows 7 or newer, required for optional software
  • Basic refrigeration cycle energy balance
  • Determine coefficient of performance (CoP)
  • Effect of heat source and heat sink temperatures on CoP
  • Compare performance between actual and reversed Carnot cycles
