Im curious to know/ figure out if duct fans are an option and how to calculate out how much or many would be needed in this type of application. - For the moment its a theoretical/planning idea. And im aware its more of a jerryrigged idea then a proper solution. I got a few estimates on a mini split ac system, but even for a single room the estimates were around $4k. So im mulling over the more outlandish ideas that might be a tad cheaper.
Some misc info.
A little while back i was considering adding a second portable ac unit to a room in the basement. There is currently one portable unit down there which is able to keep up with the temp needs pretty well. But when a dehumidifier is turned on, then the AC cant keep up and the temp slowly rises. I have temp sensitive animals down there. So the room must be kept cool at all times. - Its possible that better air circulation might help this issue, im not sure. But the ceiling is to low for ceiling fans. Even roof huggers. Between the height of the cages, and the main house ductwork and house support beams.. theres to much in the way + low ceiling. So ceiling fans dont seem to be an option.
I dont want to set up normal fans because the animals should not have direct drafts on them. So a normal fan might be to powerful even on a low setting. That being said, i already have one portable AC unit, and one dehumidifier. Id like a second dehumidifier to help keep up better. So if i added a second portable unit, then id have four various units and could arrange them to make a little bit of a circular air flow across the room. (remember when i said a more jerryrigged system?... yea.. )
But all of that would be irrelevant if i couldnt set up a second portable AC unit. Trouble is, there no where near by to vent the air in and out. So it would be a long ass duct run. And the port ac units arnt really designed with that level of power to draw the air in and out over that kind of distance. So i was considering those duct fans with a temp control for turning on and off to help move the air.
Which begs the question of how do i determine how much help would be needed? How many fans, or how strong a fan to make such a system work? - Unfortunately, the unit i have now, which i was going to use as a mathematical base, doesnt list the air flow force of its intake and extakes vents that i can see. So i cant even give a solid number for what it would need or what it currently has.
This is the rooms current setup
I havnt made a final decision cause i dont have all the info, obviously, but i was considering something like this.
The only good idea iv found so far is the mini split system. But at an estimated $4,000.. id like something so not damn expensive. So im considering not so pretty, jerryrigged systems. I would just have to make sure it would worked. The ductwork for the second port ac system in this example would be ~14ft outside the room, and 18 ft inside the room. A long duct for sure, hence the idea of the fans to help the air flow.
So if anyone can tell me how to go about finding out what level of airflow help i would need from the fans to make this work, please let me know!
Or any better ideas i dont know of, tell me those too! - I just need to come up with something that will work and not be a fortune; like a $4k mini split.
