区域供冷项目中冷却塔降噪技术分析与模拟
Analysis and simulation of cooling tower noise reduction technology in district cooling projects
摘要：
为探究冷却塔场地受限时的噪声治理方案，总结了冷却塔噪声类型及治理措施。以深圳某区域供冷项目为例，对冷却塔降噪方案进行分析、比较后选出最优方案，采用Cadna/A软件对冷却塔选用最优方案前后周边建筑物的噪声进行了计算和模拟，以验证方案的可行性。提出了在冷却塔场地受限时，冷却塔整体采用消声器和吸声隔声板相结合的噪声控制技术，可使周围建筑物受到的冷却塔噪声达到噪声限制要求。
Abstract：
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.
