Automobile air-conditioning simulator is a comprehensive education module for students of higher education, technical schools and universities to learn the basic concepts of air-conditioning systems.
Automobile air conditioning simulator can easily guide students to learn, experiment and troubleshoot exercises. Its procedures teach the basic concepts, maintenance procedures and troubleshooting methods necessary to maintain and repair modern automotive air conditioning systems.
The training simulator provides a realistic schematic diagram of an automotive air conditioning system. Controls in electrical and vacuum systems are presented in a clear and easy-to-understand manner.
Provides a check point for checking voltage and vacuum. The interconnection of the compressor, condenser, evaporator and accumulator describes the circulation of the cooling fluid. Embedded voltage probes, refrigerant leak detectors, and intake / exhaust pressure gauges are used for system evaluation and troubleshooting.
The courseware provides a complete course for learning automotive air conditioning procedures. Students master basic concepts through systematic experiments and then carry out complex troubleshooting exercises. Teach students to use logic and stepwise methods to solve problems.
Describe this simulation device to teach students the basic concepts of automotive air conditioning. Students learn how to operate testing equipment through system components. When the detection point can be evaluated and troubleshooting, the status indicator indicates the working condition of the component. The operation of this built-in testing equipment is safe and convenient.
The system constitutes a training system including: the simulator part; the student experiment manual; the user manual. The students can easily find the following components provided on the simulation board:
