广州地铁二号线空调系统高压故障原因探讨

Discussion on the High Pressure Fault of Air Conditioning System of Guangzhou Metro Line 2

广州地铁二号线电客车空调通风系统采用的石家庄王牌国祥定速空调、法维莱定速空调和山东朗进变频空调系统。主要有为顶置式空调机组、空调控制柜等组成。空调系统通过输送适宜人体的新风,改善客室空气质量,为乘客提供舒适的乘车环境。随着二号线电客车运营时间增加以及隧道环境的恶化,空调系统高压故障出现明显增加趋势,为解决此问题开展了隧道环境优化对电客车空调系统的影响调查试验,测试结果表明改善隧道环境温度能有效降低空调系统高压故障发生概率。

The air conditioning and ventilation system of guangzhou metro line 2 electric bus adopts the shijiazhuang kingpin guoxiang constant speed air conditioning,favelle constant speed air conditioning and shandong lanjin variable frequency air conditioning system. It is mainly composed of overhead air conditioning unit and air conditioning control cabinet. The air conditioning system can improve the air quality of the passenger room by delivering fresh air suitable for human body, and provide a comfortable riding environment for passengers. As electric bus operating time is increased and the environmental deterioration in the tunnel,high pressure air conditioning system failure occurs obvious increasing trend, in order to solve the problem of guangzhou metro line 2 in the tunnel environment optimization of electric bus air conditioning system investigation and experiment,the influence of the test results show that improve the tunnel environment temperature can effectively reduce the high pressure air conditioning system failure probability.
