Multiple Compressor Trainer Refrigeration Training Equipment Teaching Equipment

TCCM-C Multiple Compressor Trainer Refrigeration Training Equipment Teaching Equipment

The trainer allows to study the combined operation of compressors in a refrigeration system controlled via a control unit/PC (mod.TCCM-C) that switch on and off each compressor depending on the required cooling power.
TRAINING PROGRAM
• Study of the combined operation of compressors
• Study of the operation of a compressor pack controller (mod. TCCM)
• Use of the p – h diagram of a refrigerant gas
• Collection of the operating data and calculation of the heat balances and system efficiency
• Electric power consumption measurement depending on the number of active compressors
• Effect of the airflow rate on the condenser performance
• Data acquisition, system supervision and fault insertion via PC (mod. TCCM-C)
