Abstract
Apparatus, systems, and methods for providing cooled air to an aircraft using dry ice. The cooling apparatus includes dry ice hopper to store dry ice and feed it to a dry ice mill, which is turn mills the dry ice into an insulated vessel containing a fluid coolant. A fluid coolant loop connects the insulated vessel with a heat exchanger, and a pump transports the fluid coolant through the fluid coolant loop. An agitator within the insulated vessel is coupled to the pump, so that operation of the pump causes the agitator to agitate the mixture of fluid coolant and milled dry ice within the insulated vessel. Cool air is provided to the aircraft by an air delivery system that conveys air across the heat exchanger.
