Air Conditioning Noise Analysis and Calculation in Nuclear Power Flant

摘要

With the rapid development of nuclear power industry, people are paying more and more attention to the acoustic environment of nuclear power plants. Apart from the main control room ^{[1], the air conditioning noise of other plants in the nuclear power plant is basically calculated by designers manually or through empirical evaluation. However, different designers consider the system design noise from different starting points and perspectives, and the actual effect can only be tested in the application process. But at this time to adjust and modify the system, will bring serious losses. The three-dimensional layout design of nuclear power is the product of the comprehensive development of forward design of nuclear power and the high-speed advancement of the design work of three generations of nuclear power, such as HuaLong no.1 and AP1000, which has been widely promoted and applied. Based on the PDMS software of HVAC 3d layout design, a software for noise analysis and calculation of air conditioning system is developed. Designers can conduct noise checking while designing, so as to automate, intellectualize and visualize noise calculation, reduce manpower input and improve design efficiency. This paper will demonstrate it.}
