Automatic AC System Training Bench (SMT-AT-20)

This training bench is designed to demonstrate the complete structure and operation of a modern automotive automatic air conditioning system, using a real and operable system based on a Toyota Corolla or equivalent. It allows students to holistically study the system principles, including electrical control, refrigerant flow, and diagnostic procedures. The unit features a fully functional AC system where the compressor is driven by a three-phase motor, with a control panel for system operation and an intelligent fault-setting system for troubleshooting practice. It is equipped with detection terminals for measuring electrical parameters like voltage and resistance, and instruments such as pressure gauges and thermometers to display real-time system conditions. The sturdy, steel-framed bench is mounted on wheels for mobility and includes facilities for practices like refrigerant charging and leak detection. Its primary application is in automotive engineering education for vocational training and technician development. The key benefit is the comprehensive, hands-on learning experience it provides, enabling students to understand system operation, perform electrical and pressure diagnostics, and develop practical troubleshooting skills for real-world automotive service and repair.
