摘　　要：根据烟岗水电站地下厂房特点(多洞室群结构、发热量大、通风量大),结合工程所在地气候特点,对该大空间地下厂房进行常规通风空调方案比对。利用电站的自然冷源资源优势(尾水洞引风),提出三种改进型空调及通风方案:液泵供液直接蒸发多联机供冷与通风方案;水源热泵升温通风方案;水源热泵机组除湿调温通风方案。比对各方案技术参数,同时进行参数分析,通过比对,水源热泵机组除湿调温通风方案发电机层的相对湿度及母线洞温度得到有效控制;机组设备运行效率高;系统调节灵活、方便,送风参数具有很好的可调性。According to the characteristics of the underground powerhouse of the Yangang Hydropower Station （multi-cavity group structure, large heat generation, large ventilation）, combined with the climate characteristics of the project site, the large-scale underground powerhouse is compared with the conventional ventilation and air-conditioning scheme. Taking advantage of the natural cold source resources of the power station （drainage of the tail water tunnel）, three improved air conditioning and ventilation schemes are proposed： liquid pump supply direct evaporation muhi-line cooling and ventilation scheme; water source heat pump heating and ventilation scheme; water source heat pump unit dehumidification Temperature and ventilation scheme. Comparing the technical parameters of each scheme and analyzing the parameters at the same time, through comparison, the relative humidity of the generator layer and the temperature of the busbar hole of the water source heat pump unit are effectively controlled; the unit equipment has high operating efficiency; the system adjustment is flexible and convenient. The air supply parameters have good adjustability.
