流溪河水电站是按照第Ⅲ气象条件进行通风设计的。设计采用的夏季室外温度为33℃,相对湿度为85%;室内设计温度为30℃,相对湿度为70%。所采用的降温降湿措施是设置喷水冷却空调装置。据计算主厂房散热所需风量为50000立方米/时,最大风压为56毫米水柱,原设计选用了B_2-12型离心式通风机一台作主用,另以СТД-57-В-11型离心式通风机一台作为备用,主备用风机未 Liuxihe Hydropower Station is in accordance with the first meteorological conditions for ventilation design. The design uses a summer outdoor temperature of 33 ℃, relative humidity of 85%; interior design temperature of 30 ℃, relative humidity of 70%. The cooling and dehumidification method adopted is to set the water jet cooling air conditioner. According to the calculation of the main plant cooling required air volume of 50000 cubic meters / hour, the maximum pressure of 56 mm water column, the original design uses a B_2-12 centrifugal fan for a master, the other with СТД-57-В-11 Centrifugal fan as a backup, the main backup fan is not
