昆明地区某泵房复合通风设计

Hybrid ventilation design for a pump house in Kunming area

昆明地区夏季通风室外计算温度较低,具备较好的自然通风条件,半地下泵房采用自然通风能满足全年绝大多数时间的散热要求。半地下泵房引水泵站连续运行时间长、供水安全性要求高,为满足极端室外空气温度条件下的泵房散热要求,应同时设计机械通风系统。自然通风与机械通风相结合的复合通风系统具有运行管理简单、保证率高、运行能耗低等优点。

The outdoor design temperature for summer ventilation in Kunming area is relatively low,and it has better natural ventilation conditions.The use of natural ventilation in the semi-underground pump house in Kunming can meet the heat dissipation requirements for most of the year.For the divert water pump station of the semi-underground pump house,the continuous running time is long and water supply safety requirements are high.In order to meet the heat dissipation requirements of the pump house under extreme outdoor air temperatures,the mechanical ventilation system should be designed at the same time.The hybrid ventilation system with a combination of natural ventilation and mechanical ventilation has the advantages of simple operation management,a high guarantee rate and low operating energy consumption.
