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
