RCTC Computerized General  Refrigeration Trainer Refrigeration Training Equipment Technical Training Equipment
Description
RCTC Computerized General  Refrigeration Trainer Refrigeration Training Equipment Technical Training Equipment

This trainer is designed for the in-depth study of vapourcompression cycle; it uses a personal computer (supplied on demand), data acquisition and PC interface board, suitable transducers and sensors.
TRAINING PROGRAM
• Plant starting and safety devices intervention checking
• Analyzing the system behaviour versus the variation of:
- expansion device
- valve opening degree (when the electronic valve is used for expansion)
- air flow rate at condenser and/or evaporator
• 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
• The software of the equipment allows to enter different sections:
- system automatic and manual operation
- refrigerating circuit heat balance
- faults enabling (10)
- troubleshooting and plant operation reset
- system supervision with display of the values detected by the sensors
