Many industrial facilities are required to meet stringent noise requirements. These requirements are imposed to protect workers’ hearing and/or to meet community ordinances. The facility designer must pay careful attention to the noise level of all industrial equipment, including air-cooled heat exchangers.
Air-cooled heat exchangers are a source of plant noise. Therefore, it is important to design each unit to produce the minimum amount of noise while still meeting the thermal requirements at a reasonable cost.
This paper discusses the major noise sources of an air-cooled heat exchanger, the factors affecting the noise from each source, and how the source affects the overall noise level of the air-cooled heat exchanger.
