Automotive air-conditioner trainer allows trainees to study components and operation of automotive air-conditioning system. The educational unit features real automotive air-conditioner components, driven by an electric motor instead of the engine. The trainer is equipped with 12 faults simulation switches to enhance trainee’s troubleshooting skills.

                                     
  • The trainer includes real automotive air conditioner components such as compressor, condenser, filter unit, expansion valve and evaporator.
  • The compressor is driven by an electric motor instead of the engine.
  • The educational unit includes a front control panel that features operation switches, fault simulation switches, knobs, digital displays and gauges, and detailed air-conditioning circuit diagram.
  • Speed of the electric motor can be controlled via a knob on front control panel to investigate influence of engine speed on air-conditioner performance.
  • The trainer can simulate up to 12 automotive air-conditioning common faults, such as faults of compressor, condenser fan and evaporator.
  • The pressure gauges provided at front control panel display pressures of the refrigerant at different points through air conditioning circuit.
  • Air conditioning circuit is also provided with temperature sensors at various points through the circuit to display the system temperatures on digital displays.
  • Compressor’s electric energy consumption is measured and displayed.
  • The educational unit is equipped with a thermostat to control output temperature.
  • The trainer is equipped with a protective covering for movable parts to ensure user safety.
