Ductless Minisplit and Positive Pressure
First of all, thanks for your help, this community replies fast and is extremely helpful, thanks a lot.
I am having issues with second hand smoke and one theory as a solution is to have a window fan to generate positive pressure (and seal as much as you can the walls).
I live in a condo with Window AC Units in the walls (instead of windows). I know that Window AC Units generate negative pressure to push out the hot air they generate.
Having a window fan during summer in Chicago with super high humidity is going to be a problem. I am pushing humid and hot air inside a house I want with low humidity and low temperature, so I have the kitchen humid and hot, and then AC units and dehumidifiers running.
Now, a simple question. If I need positive pressure and a window fan does the job, would a ductless mini split generate positive pressure?
If the “machine” is outside, it shouldn’t generate negative pressure like an window unit, right? It would work as a window fan but that actually pushes cold air.
Hopefully someone can confirm this, I am willing to change all AC Wall units if that will create positive pressure.
