Keywords: Carbon dioxide, cooling system, evaporating coolant

On-board cooling systems using carbon dioxide are of interest due to possible advantages in installation space and system mass. Here, a new system architecture is introduced using CO2 as evaporating coolant in a distribution cycle cooled by ambient air, allowing reduced power consumption during flight.
