Automotive A/C Troubleshooting Training System
  • Investigate the operation of a real automotive air conditioning unit.
  • Investigate the change in the state of refrigerant as it goes through the air conditioning cycle.
  • Representing the cycle on P-H diagram
  • Calculating C.O.P of the system with various compressor speeds.
  • Investigating the effect of compressor rotating speed on C.O.P.
  • Automotive Air Conditioning Troubleshooting Training System (AT - 083)
  • Hard copy user manual

An educational unit designed to train students and technicians on the operation of the automotive air-conditioning system. The unit features typical automotive air-conditioner components, driven by an electric motor instead of the engine and includes pressure and temperature indications at various circuit points, in addition to its fault simulation capability, all system components are typical elements used in automotive technology.

  • The trainer consists of two main units, a unit that features a real typical automotive air conditioning system and an integrated stand-alone unit with a touch screen computer equipped with an interactive software of 3 main purposes.
  • The device includes typical components of a real automotive air conditioner, including compressor, condenser, filter, expansion valve and an evaporator.
  • The unit features a control panel that contains all operation switches, knobs, digital and gauge displays and detailed diagram of the refrigeration circuit.
  • The compressor is driven by an electric motor as an alternative to an engine.
  • The speed of the electric motor can be varied by a knob fitted on the control panel, to examine the system’s performance at various speeds.
  • The unit can simulate common automotive air conditioner faults, such as faulty compressor, condenser, evaporator, etc.
  • The unit is equipped with pressure gauges that indicate the pressure at various points along the refrigeration circuit.
  • The refrigeration circuit is also fitted with temperature sensors at various points, the measured signal is further conditioned and displayed on digital displays on the control panel.
  • The unit is equipped with thermostat to control the output temperature.
  • The unit is equipped with a meter for measuring electric energy consumption.
  • The unit is equipped with protective covering for movable parts to insure user safety.
  • The trainer has a touch screen computer equipped with an interactive software.
  • The unit is fixed on four caster wheels to ease moving it inside the laboratory, these caster wheels are equipped with breaks to prevent the trainer from sliding during the operation.
  • The unit is treated against rust and electrostatically painted.
