The invention relates to an alpine region subway air-conditioning system and a control method thereof. A fourth fireproof valve, an air return/exhaust fan, a third air valve, a third fireproof valve and an exhaust duct are sequentially connected, and afresh air duct, a filter and a purifier are sequentially connected. An outlet of the purifier is divided into two paths, one path is connected intoa first air mixing box through a first fireproof valve, a first air valve and afresh air fan, and the other path is connected into the first air mixing box through a second fireproof valve and a second air valve. A fifth fireproof valve, a second air mixing box, a seventh air valve, a combined air handling unit, a sixth air valve and the first air mixing box are connected in sequence. A bypass pipeline is connected with the first air mixing box and the second air mixing box, and a fifth air valve is installed on the bypass pipeline. The system is low in cost, a problem of frost cracking of thesurface air cooler in the combined air handling unit in winter is solved; meanwhile, a problem that the whole system cannot operate when the combined air handling unit breaks down is solved, automatic closed-loop control of the air conditioning system is realized, the energy is saved and consumption is reduced; and meanwhile, the environment temperature of the weak current motor room in the station is guaranteed.
本发明涉及一种高寒地区地铁空调系统及其控制方法,其中,第四防火阀、回/排风机、第三风阀、第三防火阀和排风道依次相连,新风道、过滤器和净化器依次相连,净化器出口分为两路,一路经第一防火阀、第一风阀和新风机后接入第一混风箱,另一路经第二防火阀和第二风阀后接入第一混风箱。第五防火阀、第二混风箱、第七风阀、组合式空气处理机组、第六风阀和第一混风箱依次相连。旁路管道连接第一、第二混风箱,第五风阀安装在旁路管道上。本发明成本较低,能够解决冬季组合式空气处理机组内表冷器冻裂问题,同时,解决组合式空气处理机组故障时整个系统无法运转的问题,实现空调系统的自动闭环控制,节能降耗的同时保障站内弱电机房的环境温度。
