Need a little help.
company i work for is doing an inhouse renovation project. took a room that was used for file storage and making it into a workspace. we demo'ed out the old VAV, and put in a bigger box. I saved the old (siemens BACnet) TEC, damper, and HWV. it will be the same application. just will be adding a CWV. my question is, we upsized the duct from 6in round to 8in round from the trunk line to the new VAV. they want to achieve a maximum cooling CFM of 450CFM for this box. i know i need to change the duct area subpoint. what other points do i need to change for a proper set up? thanks
