No maybe you can come up with another way to do an exchanger , I know you can use plastic pipe but I don't know the tables for figuring out what size of pipe ect to make one for a 5K or 10K BTU set up.

Yes it is one of those threads. I think I've figured out the materials to use in the chiller barrel.

They will be made known once the tank has been running for a bit.

If you manage to find a way to use plastic for the refrigerant lines in the chiller barrel, I would like to know. I would really worry about the oil eating the plastics.

I guess you could chill some glycol and run that through some plastic pipes in the sump or chiller barrel. You would have to have another pump and a secondary chiller barrel to cool the glycol, but you could use copper tubing to cool the glycol in the primary chiller barrel. That would make materials easier to get, but the size of the equipment would grow.

I am toying around with a way to have a sump designed for chiller applications that would do away with the need for a special heat exchanger.

Does anyone want to be the first to try this new and breakthrough technology? (seriously) All you need to do is build the sump to my specs, have the A/C unit modified, some lines run and your good to go. I'm going to crunch some numbers to see if this idea would provide enough heat transfer
