Bench for the study of the electronic expansion valve

BDRCEEV/EV

The bench, properly designed for educational purposes, allows the student to deepen the knowledge of the operation of the electronic expansion valve as device used to regulate the refrigerant flow feeding the evaporator of a vapour compression refrigeration plant.

Training program

  • Study of the operation of a vapour compression refrigeration plant
  • Study of the operation of the electronic valve as refrigerant fluid expansion device
  • Plant starting and safety devices intervention checking
  • Analysing the system behaviour versus the variation of the air flow at the evaporator and/or at the condenser
  • Detection of pressures, temperatures, refrigerant flow rate with plant operating
  • Determination of electronic valve superheat
  • Drawing the refrigerant cycle in the pressure–enthalpy diagram of the refrigerant gas
  • Determination of specific energy and power transferred at each plant component (evaporator, condenser, compressor)
  • Determination of the volumetric efficiency of the compression
  • Evaluation of theoretical and actual cycle E.E.R.
