Das' Chiller

[NoL]

Still the weekend, and still at my Dads, about to go buy wood for the cascade case though. I'm waiting on a pack of 20 3/8" couplings to make this a bit easier.

Good stuff. So do you go to your dads every weekend then?

 

[NoL]

Everyother.

U don't keep or take any of the phase projects with u over there so u can keep working? Or does it give you time to think about stuff that you can do with what you're working on @ ur moms?

 

[NoL]

Hahaha the amount of tools would be astagering to move over here. Its not just a pipe bender, piping, and a brazing torch mate!

Bump for an update

I asked on another forum, but I guess I should have posted it here:

You reversed the heat exchanger's connections; why?

(i.e. the 1/4" line is meant for liquid, the 1/2" line is meant for the refrigerant).

I picked up four of these H-50 exchangers myself (apparently the eBay guy still has plenty of them).

FYI, I loaded the liquid side with water, just to try to determine how it was built inside. it holds exactly 1 fl oz of liquid, which points to a straight run of 1/4" in tubing, but there's no line of sight straight through the unit. Any idea what the inside looks like?

Its a HX, so the insides are going to be coiled/windy as possible to give the greatest surface area making the whole thing more efficent.

TBH id use the 1/2 in line for the liquid aswell. That way it cools more liquid. afterall your not trying to water cool the ref...

I used it that way for less restriction to the actual unit. This is quite a test unit, in the end I may convert it to a small res'd unit. Who knows?

Actually... I've seen similar heat exchangers that have a simple inner chamber, instead of a coil. I really don't know how this one is setup.

Me neither and there's the fun

The chiller and Mach are now re-vacuuming.
