We could move air from one area to the other and seal them off, but other issues that impact is the bathroom with a constantly running vent fan and there are blowout vents to vent the nitrogen deluge system for fire protection. We will have to tie everything into the fire system to cut off all vents and intakes anyway.
My hope is that the dehumidifier will make up the exhaust air and provide a relatively dry makeup air to pressurize the rooms to reduce the dust migration into the area and help heep the air clean and dry.
The minisplits keep it cool, but the filters leave something to be desired and of course they were installed where it is inconvenient to get to them.
The lab needs the fresh air intake anyway so maybe we can kill two birds with one stone.
The air from the dehumidifier will be a little warmer, but drier as well. The load on the A/C will increase due to the hotter air, but be offset to some extent by the drier incoming air.
I guess we will see how it works.
Thanks,
