hi all

I am trying to understand what causes the compressor limits / envelope , or to be more precise the maximum evaporating temperature SST given by the manufacturer.
In that is it the temperature of the return gas that would give insufficent cooling to the suction cooled windings or is it the pressure relevant to the SST that would overload the compressor due to a high suction pressure ?

If anyone could help me it would be great;y appreciated

Thanks
