Longtan Hydropower Station Air Conditioning System Solutions Election,

This dissertation analyzes the characteristics of the heat absorption and heatemission of Long Tan hydroelectric power station's building enclosure,calculatesthe quantity of the heat absorption and heat emission of Long Tan hydroelectricpower station's building enclosure,and draws a conclusion that the heatabsorption and heat emission of hydroelectric power station's building enclosuremust be considered in considered in calculating the designing heat load of the halls of generator,bus-line, and water turbine, whereas it is on the contrary when it comes to thebus-bar space and the main transformer space.(the three formers:(the heat absorption and emission quantity of building enclosure)/(the heat load only from the inside equipments of the room)＞5%the two laters:(the heat absorption and emission quantity of building enclosure)/(the heat load only from the inside equipments of the room) ＜5%)The air-conditioning system of this hydroelectric power station includes twomain parts.One is the system of the main workshop; the other is the one of themain transformer.This dissertation analyzes two air-conditioning plans with two differentsupply air temperatures.Through the energy comparison consumed by air-conditioning system it gets the optimized plan of air-conditioning:the supply airtemperature is 22.5℃ and the maxim supply air quantity is 72×10~4m~3/h.
