This calculator will calculate the size of acoustic louvre required around an air-conditioning unit based on a given noise requirement.
The calculated louvre area includes the exhaust and intake, and assumes a maximum pressure allowance of 20Pa for PUMY and 60Pa for PUHY/PURY units.
It should be noted that the PUMY S units can handle 30Pa and the PUHY/PURY units range from 0Pa to 80Pa and therefore alternative configurations are possible.
To operate the calculator, first select the type of air-conditioning unit,
then specify the required noise limit and the distance to the assessment location. The calculator will then provide a recommended
louvre type and area to acheive the required level of attenuation.
If your unit is not included in the drop down, or you do not know your noise limit, please contact a member of the team
and we will be happy to assist.
