About Feature Technical Parameter Basic Configuration
i.About The Product
The device is designed based on the  automatic air conditioner system to holistically demonstrate the
structure and operation of the system. The device applies to theoretical teaching and maintenance training of the automatic
air conditioner system in secondary and senior vocational skill schools, normal education and training institutions.

ii. Features
1.A real and operable automatic air conditioner system is used to illustrate the structure and operation of the system.
2.The compressor is driven by a three-phase motor. A control panel can be operated to demonstrate operation and operating
principle of the automatic air conditioner system.
3.The training bench is made of advanced aluminum-plastic plate with characteristics of not less than 4mm thick, corrosion
resistance, impact resistance, pollution resistance, fireproof, and moistureproof. Its surface are processed by special craft
and spraying primer. Never fade color circuit diagram and working principal diagram are painted on the board whose
surface coating with varnish. The trainees can learn and analyze the working principle of the control system by referencing
the diagram and the real object.
4.The training bench is installed with detection terminals to detect electric signals, for example, resistance, voltage, current,
and frequency, of circuit components of the air conditioner system.
5.The training bench is installed with pressure gauges and thermometers, which display real-time pressure and temperature
at the inlet and outlet of the air conditioner system.
6.The training bench supports practice of filling refrigerant and detecting leakage.
7.The training bench's base frame is made in steel and the surface is paint-coated. Self-retention wheels are installed to
ensure that the bench is flexible, reliable and endurable.
8.Equipped with intelligent fault setting and appraisal system, include fault setting, troubleshooting and assessment
functions etc.
