本文测试了广州地铁三号线车厢内部的热环境,对其进行了分析,并利用不均匀系数与热环境评价指标对地铁热环境舒适度进行了评价。结果表明,在目前的送风方式下,载客量对温度分布影响明显,载人工况下,客室高度方向温度分层较为严重,且容易形成回风短路;现有空调设计不能满足满员工况需求,在客室站立密度为2人/m~2时,热环境不满意率最低。
This paper tests the thermal environment in the interior of Guangzhou Metro Line 3, analyzes it and evaluates the thermal comfort of the subway by using the non-uniform coefficient and thermal environment evaluation index. The results show that under the current air supply mode, the influence of passenger load on temperature distribution is obvious. Under manned conditions, the stratification of temperature in the height direction of the passenger compartment is more serious and the return air short circuit is easy to form. The existing air conditioning design can not meet the needs of full staff Situation needs, standing density in the guest room of 2 people / m ~ 2, the thermal environment is not satisfied with the minimum rate.
