HVAC Refrigeration Heating Ventilation Refrigeration

Air Conditioner Training System developed to demonstrate the operation and working principle of split air conditioners. Students will be able to follow the refrigeration cycle, explore the layout and functions of all main components and perform maintenance and troubleshooting exercises.

The didactic system is fully operable and contains all the basic components of a split air conditioner. The components are exposed and mounted on a vertical frame. The students control and monitor the experiments procedure using instruments and transparent observation points.


  • The functions available with the system are refrigeration, heating, ventilation, dehumidification, temperature and wind speed selection, timing, sleep.
  • It includes electric control unit, air conditioning unit, measuring instruments unit, power supply units and fault introduction system.
  • It shows the inner components layout and refrigerating cycle system structure
  • It includes AC voltmeter, AC ammeter, thermometer, vacuum pressure gauge, pilot lamps and real-time LED status.
  • The main control board is covered with a transparent board for process observation; schematic diagram of control system and relative test points; sight glass in the pipeline is used to refrigerant status observation; HV pipeline is marked with red, while LV pipeline with blue, relative components are all labeled.
  • It includes a connection area for electrical control circuit of outdoor unit for students hands-on ability training.
  • It includes fault introduction system
