Hey,
I'm designing an HVAC system for a laundry building. I have vacuum equipment (Vacuum press and Vacuum Ironing boards ) in the space which have a vacuum outlet the is taken outside the building through individual ducts. When all machines are operational, 877 l/s of hot air and moisture would be extracted to the outside. My question is does this air come from the space it self and does this cause negative pressure in the building if it does and what are the usual solutions for dealing with this kind of case. I was thinking about providing fresh air to maintain positive pressure with a variable frequency drive motor controlled by a differential pressure sensor.
