The simple air-conditioning system model is a part of the refrigeration and air-conditioning educational unit. By connecting the model to the base unit electrically and hydraulically, a complete refrigeration circuit is created to simulate a simple air conditioning system.

                                     
  • This model demonstrates the principles of a room cooling and the components of a simple air conditioning system.
  • The components of the model are an air duct with a transparent front, a blower for air transport, an evaporator as air cooler, an expansion valve, solenoid valves and refrigerant quick connections.
  • The blower is provided with throttle valve.
  • The thermostatic expansion valve acts as expansion element.
  • Air volumetric flow rate, temperature and relative humidity are measured before and after the evaporator by sensors.
  • All components are clearly arranged at the model.
  • The software operates the individual components, system and fault simulation.
  • The unit is provided with an air outlet.
  • The model is connected to the base unit electrically by data cables and hydraulically by refrigerant hoses.
