按照铁道部开行“绿色列车”要求,乌鲁木齐铁路局对其管内6对旅客列车车厢内部空气质量和微小气候现状进行了调查,并采用空气质量综合评价指数法对调查结果进行了评价。调查结果表明,特快空调列车车厢内部空气质量和微小气候均符合国家标准;普通空调列车和旧车型车厢内部的温度、细菌总数等部分指标超过国家标准。根据旅客季节性和阶段性变化情况,控制列车空调机组风机风量,可有效改善车厢内部空气质量,降低能耗;夏季将空调列车车厢内部温度提高1℃,使其保持在25～27℃,可提高旅客满意度21%,降低油耗5.4%,并减少CO2、NOX等污染物的排放量,减轻对环境的影响。
According to the “Green Train” requirement of the Ministry of Railways, Urumqi Railway Bureau investigated the internal air quality and the microclimate status of the six passenger train compartments in their pipelines. The results of the survey were evaluated by using the comprehensive air quality assessment index method. The survey results show that the internal air quality and the microclimate of the express train air-conditioned train meet the national standards; some indicators such as the temperature and the total number of bacteria in the ordinary air-conditioned train and the old model train car exceed the national standards. According to the seasonal and periodic changes of passengers, controlling the air volume of the air-conditioner of the train air-conditioning unit can effectively improve the air quality inside the carriage and reduce the energy consumption. In summer, the internal temperature of the air-conditioned train carriage is increased by 1 ℃ to keep it at 25-27 ℃ Increase customer satisfaction by 21%, reduce fuel consumption by 5.4%, and reduce emissions of pollutants such as CO2 and NOx to mitigate the impact on the environment.
