Hi all, as the title suggests i'd like to ask about total SSH. Specifically refrigeration.

It's not always possible or practical to have the guages attached to the evap, so you end up having to deal with pressure drops, 50m pipe runs etc and end up checking the superheat at the condensing unit.

I've heard/read that about 15K shouldn't cause any problems. I tend to make sure that the compressor's not too hot and that it's not rattling away and sweating like the preverbial.

So i was wondering if there's a definitive answer, or because of the random length of pipe runs a ball park figure is the best way to go eg. 15k

Any thought's would be welcome

cheers
