Water intake temperature calculation of air conditioning system of an underground hydropower plant

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.
