TCC Computerized Trainer For Studying The Hermetic Compressor Refrigeration Training Equipment Vocational Education Equipment

This trainer use so that students can also learn new techniques of data acquisition by the use of proper instruments and of a PC, besides understanding the issues concerning compressors.
TRAINING PROGRAM
• Plant starting and safety devices intervention checking
• Analyzing the system behaviour versus the variation of:
- liquid expansion device
- valve opening degree (when micrometric expansion valve is used)
- air flow rate at condenser and/or evaporator
• Examining hermetic compressors and their characteristics
• Assessing the quality of a compressor
• Determining the power of a compressor
• 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 carries out:
- the heat balance of the refrigerating circuit
- the system supervision with the display of the values detected by sensors
