(1)缺少与烤漆房有关的环保意识。由于国家对烤漆房在环保方面的统一要求和检测规范不像对汽车尾气那样严格,所以汽车维修企业对烤漆房在环保方面的配置基本上没有特殊要求。部分汽车维修企业甚至认为,针对烤漆房排放的燃烧废气和喷漆烟雾而加装净化装置是“舍本逐末”的投资。 相似文献

由于纯电动汽车动力蓄电池储能有限,所以,燃料电池以高效率、无污染、高可靠性的特点成为电动汽车增程器的研究热点。文章以市场上某款纯电动汽车为研究对象,将甲醇燃料电池增程器布置在车辆前舱内,对不同车速下燃料电池增程器三维模型的温度场分布进行仿真。仿真结果表明:车辆静止时,甲醇燃料电池以额定功率工作会影响前舱部件正常工作,当车辆以超过30 km/h的速度行驶,可以忽略燃料电池增程器对前舱部件的影响。试验结果验证了仿真结果的准确性,对于实车燃料电池增程器的布置和控制策略的制定具有一定的参考价值。 相似文献

Ventilation system in a bus is employed to provide good indoor air quality and thermal comfort for passengers. Poor ventilation system will increase the concentration level of air contaminants which could affect the passenger’s health. The presence mixing ventilation system used in many buses is not efficient in removing the air contaminants from the passenger compartments. This article presents a study on the effects of using different ventilation setups on the concentration level of gases and particulate matters inside a passenger compartment of a university’s shuttle bus. The goal is to find a suitable layout of the air supply diffusers and air return grilles that would lower the concentration level of contaminants inside the passenger compartment. Field measurements were carried out to quantify the concentration of gases (carbon monoxide, carbon dioxide and formaldehyde) and particulate matters (PM1, PM2.5 and PM10). The measurements were done at the front section of the bus compartment, close to the front door. The data were acquired in the morning, afternoon and evening hours during a clear and sunny day. The bus travelled along an in-campus road with no passengers. A simplified three-dimensional model of the bus compartment was developed using computational fluid dynamics software. Flow analyses were carried out to predict distribution of gases and particulate matters concentration. The concentrations of carbon dioxide, carbon monoxide, formaldehyde and particulate matters obtained from the field measurements were used as boundary conditions and for validating the computational model. A parametric study was carried out to identify a suitable layout of air supply diffusers and air return grilles that would lower the concentration level of the air contaminants. Two types of ventilation systems were considered namely a displacement ventilation and an underfloor air distribution. Results show that the underfloor air distribution system is more effective in reducing the concentration level of gases and particulate matters inside the passenger compartment compared to the displacement ventilation system. 相似文献
