Expansion noise - capillary tube into evaporator

[desA]

If you post the compressor volumetric flowrate we can then begin to see what the cap is doing and if the original length is right or your new numbers are right.

I'll write up the compressor details tonight. Excellent point.

There are of course a number of tests you can do before breaking the system to see how close your original cap is.

I agree - absolutely. I would like to push the current arrangement, as it stands, to its absolute limit. Once we've reached the end of what this can deliver, we can modify the piping. The final cut is so terribly terminal, isn't it?
