Educational simulator represents a proper and natural adaptation to the new demands of labour market requiring high training levels of all the operators of air-conditioning systems installed in great industrial and business complexes. This equipment also includes an industrial controller that enables a detailed analysis of the automatic control system for an air-conditioning installation at the variation of operating parameters. It must necessarily
be connected to the PC.
TRAINING PROGRAM
• Studying the transformation the air undergoes when crossing the various sections of an air handling unit, with the aid of the psychrometric chart
• Assessing the air supply conditions to meet the thermo-hygrometric needs of the room having to be airconditioned
• Analyzing the operation of temperature and humidity regulators for air-handling unit
• Proportional and ON/OFF control
• Air dampers control according to temperature
• Antifreeze function
• Control of alarms
• Supervision of technical installations
