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
