The base unit of refrigeration and air conditioning training system 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
