[Abstract]:Hydropower is a renewable energy source, which has less impact on the environment. Under the background of the global energy crisis, our country is vigorously developing hydropower. The main function of the ventilation and air conditioning system of underground powerhouse of hydropower station is to control the thermal and wet environment in the factory building, so as to ensure the normal and stable operation of the process equipment and the comfort of the working environment of the personnel. Through a large number of site tests of hydropower stations and the investigation of related documents, it is found that most underground hydropower stations have some problems in the design of ventilation and air conditioning systems. For example, they do not have a deep understanding of the characteristics of equipment heat dissipation. The calculation value of waste heat load is on the high side, and the selection of air treatment scheme, the calculation of system design air volume, etc., are simply selected according to experience, and the method of scheme selection and design air volume determination is not clear. These problems may lead to the mismatch between system equipment capacity and demand. Therefore, this paper will discuss and study the optimization of system design scheme, and find a more reasonable and scientific way to determine the residual heat load of the system. This paper puts forward the method of determining the optimal air treatment scheme and calculating the design air volume of the system correctly. This paper is one of the research contents of the project 51178482 supported by the National Natural Science Foundation of China "formation mechanism and energy saving regulation of thermal and wet environment of deep buried underground hydropower station". In this paper, the functions and working time characteristics of various equipments in the operation of hydropower station are summarized, and the heat dissipation characteristics of the equipment are summarized, including the intensity characteristic, time characteristic and space characteristic of the equipment. Based on the analysis of the heat transfer characteristics of the equipment and the relationship between the heat emission of the equipment and the waste heat load, based on the problems existing in the calculation of the heat dissipation of the existing plant equipment, a more accurate formula for calculating the residual heat load in the plant is put forward in this paper. The formula can reflect the actual working time of the equipment and the heat transfer characteristics of the equipment, and is closer to the real value of the residual heat load in the plant. Secondly, this paper induces eight feasible air treatment schemes for ventilation and air conditioning system of main workshop, and analyzes the influencing factors of system design air volume. According to the principle that the temperature and humidity parameters of all places do not exceed the design value, according to the equation of heat and humidity balance, The method of determining the system design air volume and the cooling rate of air treatment equipment corresponding to various air treatment schemes and ventilation processes is derived. In this paper, the feasibility, adjustment, environmental impact, investment, energy consumption, operation cost and other technical and economic evaluation indicators are compared and analyzed. The factors that affect the selection of each project are summed up, and the factors, namely, outdoor air inlet parameters, underground wind tunnel's pretreatment capacity for fresh air, and the residual heat load in the plant, are analyzed and determined more deeply. Finally, taking BHT power station as an example, the air treatment scheme of the power station is determined by using the scheme optimization method proposed in this paper, and a series of analysis and comparison between the scheme and other schemes are made. The analysis results show that the scheme selected by the optimal selection method is the most scientific. Therefore, the scheme optimization method proposed in this paper is feasible and reasonable.
