Besides the air conditioning system used to cool the air in the cabin for the passengers an additional on-board cooling system is necessary for food and beverages.
This function is achieved either through several individual air chillers distributed in every place where cooling is required or with a high power centralized cooling system located in one place. The cooling capability is distributed by a liquid loop carrying cooling in every place where it is required.
In all these locations a heat exchanger connected to this liquid loop converts the cooling power into air cooling.
Liebherr supplies complete supplemental cooling systems as needed on board commercial aircraft or any other military application.
