Summarizes the typical application forms of reservoir water in air conditioning systems of underground powerhouses of hydropower stations, and establishes an evaluation model based on the concept of energy efficiency ratio of air conditioning systems. Taking a hydropower station as an example, simulates and calculates the energy efficiency ratio of different air conditioning system types using reservoir water. The results show that under the water temperature and climate condition of this hydropower station, the best air conditioning scheme is using the reservoir water as the cold source of the primary surface cooler to precool the outdoor air, and then as the cooling water of the chiller.
