Hello,

I am a process engineer currently working on a project concerning a low temperature operation. I try to make a proces scheme for an energy efficient cooling system in which part of the refrigrant-condensation is accomplished by using 'waste-cold' from a cold product stream. However not enough cold is available for the complete condensation and so additional cooling is required (preferrably) with an air condensor. This means two compressors and a 'high' and 'low' temperature condensation steps.

Is there someone who can tell me something about commercially available systems for the above described situation?

Thank you in advance,

Bart
