Abstract: In order to solve the problems of poor comfort, high operation and maintenance cost and low reliability of locomotive air conditioning, a locomotive air conditioning system with perfect function and strong practicability is designed from the perspectives of energy-saving transformation and intelligent control design. Firstly, according to the system requirements analysis, the overall design and function design of the system are completed. Secondly, the core functions of the system are realized from three aspects: intelligent air conditioning controller, variable frequency air conditioning unit and integrated intelligent air conditioning working mode, and the system is applied to specific practice. The results show that the locomotive air conditioning system operates normally, reliably and stably, and the realization of each functional module meets the relevant design requirements.
