Looks great Kg.... and somehow familiar
With the constant fresh air input condensation isn't really an issue. When running, my setup never fully reaches saturation. The mist is dissipated a foot or so past the outlet.
If it does then things are out of balance somehow. Tweak your airflow/moisture output, condensation is a waste product in this case. However, I do have pans at the bottom to catch the run off from watering. In addition, make sure the humidifier outlet tube maintains a degree of slope so any condensation inside the tube is allowed to run back into the humidifier and then be recycled.
Your performance numbers look good.... and be sure to install that second fan and power supply. It's tempting to do but don't slack on that issue.... it can come back to hurt ya real bad.
You might end up moving the humidifier output closer to the fan.... depends if the negative pressure differential developed by the inlet air velocity is sufficient enough to induce proper blending of the two from that distance
In other words.... make sure the fan sucks the mist into the airflow
Its a little counterintuitive but with this type of system, you don't want to see the mist sinking or collecting somewhere. We want it fully blended to get the maximum temperature drop (latent heat of vaporization)
just for fun, a little about Bernoulli from the master
and an old school vid on refrigeration
