BS EN 13487 is one of a series dedicated to air-cooled heat exchangers.
BS EN 13487 provides information for assessing and presenting the acoustic emission characteristics of heat exchangers under stationary operating conditions.
BS EN 13487 is applicable to self-standing forced convection air-cooled refrigerant condensers and air-cooled liquid coolers "dry coolers" and air coolers.
BS EN 13487 on air-cooled heat exchangers is useful for:
When hot process fluid flows through the tubes of an air-cooled heat exchanger, heat is rejected to the surrounding air. The cooled fluid is returned to the facility, while the heated air is discharged into the surrounding environment.
BS EN 13487 offers ways to determine the sound power level of units. Some of them are specifically adapted to provide results with low uncertainties, by using laboratory class or engineering class acoustic methods under highly controlled working conditions. Those results are suitable for certification, labelling and marking purposes. It helps to minimize unnecessary vibrations and sounds in the air-cooled heat exchanger and improves the efficiency of heat removal.
BS EN 13487 is helpful for determining sound power levels LW, expressed in decibels (dB) with reference to a sound power of one picowatt (1 pW), of airborne acoustical noise within the specified frequency range of interest and for prescribed operating conditions of the appliance to be measured:
