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。
The design features of two central air conditioning systems and one main ventilation system of the Three Gorges Left Bank Power Station are introduced, and their operation are analyzed. According to the characteristics of the service area, 1 # central air-conditioning system is designed as an open system, large space using a spherical nozzle outlet; 2 # central air-conditioning system designed for closed systems, the use of double loop pipeline; in order to ensure system reliability, Have considered enough spare equipment. The main ventilation system uses low-temperature corridor cooling, air supply filtered twice, from the tertiary fan relay into the air-conditioned area.
