Two stage Sabroe
I have been doing a survey today on an old Sabroe pack. The compressors are TSMC 116S and are running on R69L. The compressors are over twenty years old, does anyone have a manual for these? and how can i tell that my interstage saturated pressure is most efficent. I seem to remember there was a calculation for working out the interstage pressure, something like ''the squre root of the sst x sdt''. Any ideas and feed back would be most welcome.

easiest way is to plot the conditions you have on Coolpack and then play with the interstage pressure and keep checking the calculated COP.

Hi Ian,
Yeah i tried Coolpack, but my version doesnt have R69L(R403B) in it. Does your version?
