Trying to make the DIY "Cheapo" AC system work

Philip, just click the "edit" button on the same posting where the picture is displayed. Now scroll down to the "attachements" and there's your pic. It also shows a "delete this attachement" button/link. Press it an't it's gone. Now, go and resize your original picture using whatever program on your pc (photo editor) to max 640x640. Then upload THAT edited version to your post you are currently EDITING.

Here's a crude drawing of how my add-on "chiller room" DIY AC system finally ended up working for me. 1: Window AC unit (10k BTU), in wall down near floor, blows onto: 2: 400 CFM "squirrel cage" fan intake, sitting on vibro mat on floor facing upward towards AC unit; connected to: 3: metal adapter and 10" flexible insulated ducting, going up to the ceiling and: 4: another metal adapter that goes thru an existing vent in the wall into the studio. This is the cool air input to the room. 5: farther down the same wall, up high, is a vent 6: it feeds an 8" duct 7: to an outlet in the ceiling of the "chiller room". This is the warm air return. This setup has kept me fairly cool this summer even w/ all the computers on. It could be cooler, and certainly quieter, some challenges remain, but it has been far more pleasant to work in here since I got this working. Thanks to all who helped. Philip Perkins CAS

Glad it's working for you -- perhaps not ideal and perfect as you indicated, but it seems as though it's acceptable to you and basically meeting your expectations! Any chance you can post pictures? :roll: :twisted: --Keith :mrgreen:

Here's pic from tonight, side view in the chiller room. You can see the big black duct that is feeding cool air from the squirrel cage fan (box on floor) up into a register high on the wall (that goes into the studio). The AC unit is behind the fan and the duct. The small white box at the top of the frame is the return air outlet. This box is actually a device made for clothes dryers to keep the warm air in the laundry room--it has a door inside it that can route the incoming air out the bottom (the warm air return in this case) or close that and route the air onward to the black box hanging from the ceiling next to it, which is a vent fan (for when the AC isn't needed). Still to do: make the vent fan work better (bigger duct), remount the AC unit so it is less noisy. But in any case--much cooler mixing in the studio this summer! thanks Philip Perkins
