We are using a VRF HVAC System at a PK-8 School in Alexandria. Has anyone had success getting the appropriate data from Mitsubishi or other Manufacturers to be able to run the necessary Acoustic calculations for the prerequisite? We've had a very hard time obtaining needed data and are concerned we may not be able to do the design-side calculation method. Would love feedback from anyone out there who has succeeded. Thanks!

Sorry you're having a problem getting sound data. A lot of manufacturer's do not have data because it is an extra cost for them to get the testing performed. Your best but is to try to contact the sales rep in your area (or have the mechanical engineer contact them) and tell them you need the data. I have not had much luck getting information from Mitsubishi, personally. Good luck!

Daikin AC typically has sound data. http://www.daikinac.com/commercial/docsOverview.asp?sec=docs They are very similar sized unit and you may be able to substitute the data.
