摘　　要：水库水可作为地下式水电站厂房空调系统的冷源。为了研究空调系统的取水水温,总结了现有水库水温计算方法和部分水电站所属的水库类型;对类比法、经验公式法、数学模型法3种水库水温计算方法进行了对比分析,并提出了抽水蓄能电站适用的计算方法。根据传热学原理,结合地下式水电站的布置特点,分析了可能引起取水温升的环节,给出了不同位置取水的水温修正方法,为地下式水电站空调系统设计提供参考。Reservoir water can be used as the cold source of the air conditioning system of underground hydropower plants.In order to study the water intake temperature in the air conditioning system,summarizes the existing calculation methods of water temperature in reservoirs and the reservoir types of some hydropower plants.Compares and analyses three calculation methods of reservoir water temperature:analogy method,empirical formula method and mathematical model method.Puts forward the applicable calculation methods for pumped storage power plants.According to the principle of heat transfer,combined with the layout characteristics of underground hydropower plants,analyses the procedures that may cause the water intake temperature rise and proposes the water temperature correction methods for different water intake positions,so as to provide reference for the air conditioning system design of underground hydropower plants.
