TF&F PLMC has the ability to achieve very low Power Utilization Efficiency (PUE) =<1.08.
It does not require any chillers or any vapor compression.
One of the PLMC cooled facility embodiments is illustrated below
for the PetaFlop computing container design proposal.
It involves R-134a condensers on the roof, processor count,
cooling required, thermal budget, refrigerant flow and pumps.
