This article describes the research on the technology of intelligent control of air-conditioning system for rail transit vehicles. The system uses frequency conversion air-conditioning units, which integrates refrigeration, heating, fresh air, exhaust, air purification, dehumidification, and passive pressure wave protection to improve passenger comfort. At the same time, the air-conditioning intelligent operation and maintenance system automatically diagnoses and predicts the failure of the air-conditioning system, which can improve the efficiency of the entire after-sales service team and reduce the company"s maintenance labor costs. This research can provide a technical reference for the intelligent research and application of air-conditioning systems for rail transit vehicles.
