Analysis and simulation of cooling tower noise reduction technology in district cooling projects

To investigate the noise control scheme when the cooling tower site is limited, summarizes the types and control measures of cooling tower noise. Taking a district cooling project in Shenzhen as an example, analyses and compares two schemes, and selects the best one. To verify the feasibility of the scheme, calculates and simulates the noise of surrounding buildings before and after the optimal scheme with Cadna/A sofeware. Proposes that when the site of cooling tower is limited, adopting the noise control technology of the combination of muffler and sound absorption and insulation board can make the noise of the surrounding buildings meet the noise limit requirements.
