The base unit of refrigeration and air conditioning training system (AR – 001) is designed to demonstrate the fundamentals of both the refrigeration and air conditioning systems and their components. The unit allows observation of the systems operation, in addition to a software to perform experiments and analyze the experiments results

  • The base unit is extended into complete refrigeration circuit with one of the four models.
  • The unit is provided with ON/OFF switch and emergency switch.
  • The unit is provided with condensing unit (compressor, condenser with add-on fan, receiver), solenoid valves, filter/drier, gauges, pressure switch, humidifier and refrigerant hoses.
  • The unit is equipped with self-sealing couplings to reduce the refrigerant loss to a minimum.
  • The solenoid valves are used to control the air conditioning / refrigeration system.
  • The unit is connected to the other models
  • hydraulically using refrigerant hoses and electrically with cables.
  • The components are arranged in a way that introduces trainees to the refrigeration and air conditioning components and allows the trainees to follow the path of the refrigerant.
  • Temperatures and pressures in the system are recorded by sensors and displayed dynamically in the software for system operation.
  • The effect of parameter changes can be tracked in log p-h diagram at the software.
  • The unit is provided with USB port to be connected to a PC
