三峡左岸电站暖通空调系统设计与运行

介绍了三峡左岸电站的2个集中空调系统和1个主通风系统的设计特点,并分析了其运行情况。根据所服务区域的特点,1#集中空调系统设计为开式系统,大空间采用球形喷口送风;2#集中空调系统设计为闭式系统,采用双循环管路;为保证系统的可靠性,均考虑了足够的备用设备。主通风系统利用低温廊道降温,送风经两次过滤,由三级风机接力送入空调区域。

HVAC system design and operation of Three Gorges Left Bank Power Station

Presents the design features of the two central air conditioning systems and one main ventilation system of the power station and analyses their operation.According to characteristics of the zones served,No.1 central air conditioning system is designed as an open system and supplies air with spherical nozzles in large spaces;No.2 central air conditioning system is designed as a closed system with double loop pipelines;and both of them are equipped with sufficient stand-up devices for guaranteeing the systems’ reliability.The main ventilation system uses the low temperature gallery for cooling and supplies the cold air to air-conditioned areas by three-stage cascade fans after two-stage filtering.
