Thanks, I have bookmarked this for future reference. Practical research is always valuable.

The article below alone could cause an extended discussion in the optimization sub-forum.

4-1336 Discus™ "Optimized Medium Temperature Models Bulletin".

Not so USIceman?

This is a good collection of information, but I'm curious about potential copyright infringement on the website owners part.

In any event, I found one PDF of particular interest: 4-1334 Low Condensing Temperature Bulletin

It appears Copeland has finally lowered their minimum acceptable condensing temperatures. This is good news!

I said "finally" above as this topic has been verboten for many years. Even though I was doing it about 25 years ago when the first Discus compressor became available.:D
