暖风空调的性能直接影响电动客车的动力性、舒适性及续航里程.为了对锂电池冷却水、电机冷却水余热及正温度系数(PTC)热敏电阻加热器加热进行综合管理,该文设计了一种基于多种制暖并存分阶段联合控制式纯电动客车暖风空调系统,提出了在-25～25 ℃之间,不同温度,分阶段空调制热的系统控制模式.通过分析电动客车空调室的热负荷,建立空调系统数学模型,运用模糊神经网络算法进行控制,并对装有该暖风空调系统的客车进行了低温试验.结果表明:该空调运行良好,能够满足人体的热舒适性评价指标,达到了人群热舒适性温度22.1～27.4 ℃的范围.%The power,comfort and mileage of electric bus are affected by the performance of warm air conditioners.A kind of warm air conditioning system based on multi-stage heating and co-existence control was designed to provide integrated management for lithium battery cooling water,motor cooling water waste heat and positive temperature coefficient (PTC) heating.The system of air conditioning was heated between-25℃ and 25 ℃ by multi-stage to different temperatures,and the heat load of air-conditioned room of electric bus was analyzed.The mathematical model of the air conditioning system was established,and the fuzzy neural network algorithm was used to control the heat load of the air-conditioned room.The results show that the air conditioning system works well and achieves the expected affects (22.1-27.4 ℃),which satisfies the human body's thermal comfort evaluation index.
