I have been reading it is a good idea to cool the air coming from the pump before it goes to the tank and have a water trap after the cooler. Alot of guys have used an automotive evaporator or condenser to cool the air. I have an old a-coil from home unit and was thinking of using it. I was going to plumb it between the pump and tank and have a water trap before it goes into the tank. Also would add a fan to blow into the a-coil just like your furnace does to dissipate the heat. Of course I would have to eliminate the expansion valve on the a-coil to remove that restriction.
Any thoughts?
The only things I can think of are 1) be sure the coil is internally clean and 2) what's the tube size? If it's too small, it could be a restriction to flow rate.
Is the A coil the condenser or the evaporator? I would think the condenser would be more effective though either would be an improvement. You will also need a catch tank for the water that will condense out as the air cools.
As far as restrictions go, it looks to be ok. It has a 3/8(I think) small line going in and that splits off into smaller 1/4(I think) lines an goes into the core.
The a-coil is the evaporator portion that is in the house above the furnace fan. The condensor is the part outside and would be way too big to mount anywhere. I have that unit also and was going to scrap it.
Of course you are right. I engaged my typing finger before I put my brain in gear. I was thinking of automotive unit. I would think the home evaporator would work great. You would need to have a small tank to catch the water before it got to your compressor tank but that should not be too hard to find either. This is something I have also wanted to do. I hope you will post your progress along with a few pictures as you go. Good luck.
The more I think about it the more i am leaning towards a trans cooler or condensor from a car/truck. The a-coil is so big and takes up alot of room I don't have. I can pick up a trans cooler from the local pick n pull for 10.00 and it would be small enough that it would not take up much room.
I am thinking going up the wall from my compressor to the cooler, then out of the cooler down to a tee w/a leg w/a drain at the end, then back to the tank.
That will work but I think you may get more water than you think. I would be tempted to pick up a 10 gallon air tank and run through it to catch the condensation.
Got a new camera,see if this works.One is the "infamous" Franzinator....with external cooling coil(total loss system,IOWs 1/4" tubing taps into water supply but instead of tying back in,it simply fills a bucket.Only use this when AC is runnin non-stop.....and the water is simply adj to dribble).
The other pic is a copper coil.Its 3/4 that was simply coiled around a big sander drum or sumthing?Anyway its gonna be installed after comp.....
I need to tig up another expansion chamber on comp outlet...then plumb the above coil in....just need the time to do it....duh.
I've just added this, and a few more pics of this to my project journal.
