II Training Program
Plant starting and verification of the safely devices intervention
Study of the operation of a thermostatic expansion valve
On-off control
Analysis of the system behavior at variation of:
- Number of evaporators
- Condenser evaporations air flow
- Thermostatic valves superheat
Drawing the cycle in the pressure-enthalpy diagram of the refrigerant gas
Data collection and calculation of:
- Thermal balances at the evaporators, condenser, compressor
- Refrigerant mass flow
- Compressor volumetric efficiency
- Thermostatic valve superheat
