Computerized industrial refrigeration trainer

TRIC/EV

This trainer is designed for the study of industrial refrigeration whose main aim consists in controlling the temperature and relative humidity of one or more cold rooms.

Training program

  • Plant starting and safety devices intervention checking
  • Studying the operation of a thermostatic expansion valve and its calibration
  • Proportional control
  • Correlation between evaporation temperature, room temperature and relative humidity in positive-temperature rooms
  • Analyzing the system behaviour versus the variation of:
    • valves opening degree
    • condenser air flow
  • Plotting the cycle in the refrigerant pressure-enthalpy diagram
  • Data acquisition and calculation of:
    • heat balances corresponding to evaporator, condenser, compressor
    • refrigerant mass flow
    • ideal and actual EER
    • volumetric compression efficiency
    • condenser exchange surface
    • heat transfer coefficient between air and refrigerant in the condenser
    • heat losses through the room walls
  • The software of the equipment allows to enter different sections:
    • system automatic and manual operation
    • faults enabling (12)
    • troubleshooting and plant operation reset
    • system supervision with display of the values detected by the sensors
