Dual Zone AC & Climate System Trainer

Fully functional dual zone air conditioning and climate control system trainer is installed in a mobile aluminium frame. This training board – simulator is specially designed to help technical students understand electronics, mechanics, the theory of air conditioning and climate control system better. The educational training stand is based on Audi/VW OEM components. The integrated air conditioning and climate control system shows the different operation modes. The training board-simulator is a great educational tool that allows students to learn the structure of air conditioning and climate control system, study its components, perform various measurements, tests and other diagnostic procedures, to use diagnostic scan tools or other special tools and equipment. In order to show all the functions of climate control this educational aid has installed the auxiliary heating unit which could be petrol or diesel on request.

Technical specifications and functions

  • Integrated electronic 2C – Climatronic heating and air conditioning system
  • Monitoring operation modes of air conditioning and climate control system
  • Visible HVAC compressor, electromagnetic compressor clutch and its operation modes
  • Installed pressure gauges can monitor the pressure distribution of R134a refrigerant in the high and low pressure sides (circuits)
  • Visible HVAC (heating, ventilating and air conditioning) mixing unit with its operation modes
  • Visible the operation of airflow flaps
  • Ability to monitor and control changes of the parameters of each system component:
    – The air flow fan speed
    – The air flow flap positions
    – The interior (inside) temperature
    – The Refrigerant R134a pressure changes depending on the speed of the cooling radiator fan
    – The rate of the temperature change depending on the speed of the airflow radiator fan
    – The air flow flap position according to operation modes: defrost, air recirculation (fresh air) or footwell
  • The training stand has a complete electrical wiring diagram with built-in banana plug jumpers for measurements and simulation of the system fault codes
  • Ability to simulate more than 15 system faults by disconnecting banana plug jumpers. Ability to monitor the changing operation mode of each system component
  • The training stand has integrated auxiliary heating unit which could be petrol or diesel on request. The heating unit delivers heated coolant fluid to the heating exchange unit to enable the climate control run and show how it cools or heats the air.
