Abstract

A case study was initiated with the aim of controlling the noise from axial (propeller type) condenser fans in an air-handling unit. The unit of concern was a 15 ton heating/cooling unit, with a pair of 30 inches diameter propeller fans used to move outdoor air over the condenser coil. It was found that the newer generation of `high-solidity' low-noise axial fans is an effective means of significantly reducing the noise impact of an existing rooftop air-handling unit.
