| In recent decades, energy crisis and environmental problem has increase seriously. Hydropower as a clean and renewable energy, operate flexible and has the benefit of comprehensive development and utilization, as the priority position of development for the developed countries. Especially with China’s sustained economic growth, and the improvement of living standards, the demand for energy is growing faster. Hydropower plant ventilation design related to the use time, safety, effective, economy of the hydropower station operation, it is essential for a successful hydropower station. With the development of hydropower, the number and scale of hydropower station increase dramatically, the design and research of hydropower plant ventilation become the main task for the HVAC professor.Firstly, this paper will introduce the characteristics of the hydropower station, expound the influence factors of system design air volume, summarize the calculation methods of heat load and air volume’s design. Taking Yinhanjiwei Sanhekou hydropower plant project as an example, to solve the problem of ground ventilation design effect main factory lack of comfort consideration and deputy factory in the form of a single ventilation to different functions of plant electrical room, the main factory combined with mechanical ventilation and natural ventilation, deputy factory according to different room’s function put forward the ventilation scheme.Secondly, through the example of xinjiang xiabandi underground hydropower station, to learns the technical feasibility and economical scheme of underground hydropower station, to summarizes four kinds of ventilation exhaust scheme and introduces the air distribution of each scheme. According the temperature humidity parameter requirements in the xinjiang xiabandi project, calculate the corresponding system design air volume and select equipment for different design air volume.Finally, this article will comprehensive analysis of four kinds of ventilation scheme from technical and economic evaluation index, such as feasibility, complexity, temperature parameters, investment, operation cost and so on. Through the scheme comparison, to determine the recommended ventilation exhaust scheme. |
