Domestic Refrigerator Refrigeration Training Equipment Teaching Equipment

DR-2 Domestic Refrigerator Refrigeration Training Equipment Teaching Equipment

The equipment has been designed to allow students to see in detail the operation of a 2-door (mod. DR-2) domestic refrigerator.
TRAINING PROGRAM
• Domestic refrigerator operation analysis
• ON/OFF regulation: the refrigerated room thermostat
• Evaluation of the cycle pressures and of the corresponding evaporation/condensation temperatures
• Drawing of the cycle on the pressure enthalpy diagram
• Evaluation of the specific energy exchanged at the evaporator and at the condenser
• Cycle EER evaluation
• Fault insertion
