谈大型公共建筑地下室变配电房通风空调设计

Design of air-conditioning and ventilation systems for large-scale public underground power distribution and transformer house

提出了消除室内余热所采用的两种方案,以同一变配电房处于两个不同地区为研究对象,根据不同室外气象参数计算出相应的通风换气量,分析了在实际设计安装过程中土建条件对两种方案的影响,选择了合理的通风空调设计方案,并对通风空调运行能耗的控制提出可行性方法,最后介绍了变配电房通风换热与变配电房消防气体灭火系统相结合的设计和运行方式。

Two schemes is presented to eliminate the indoor heat excess,as a identical substation for studying object,the detail calculation of the relevant ventilation is made according to the different outdoor meteorological data,then the analysis of the civil condition effecting to the two schemes in the actual installation process is made,finally,the reasonable ventilation air-conditioning design scheme is selected,and the feasibility method for the operating energy consumption＇s control is presented.In the end,the combined design and operation mode of the ventilation-heat exchanging and fire gas fire-extinguishing system.
