Un système de refroidissement au CO2 pour le véhicule blindé HMMWV.

An improved CO2 cooling system for the up-armored HMMWV.

Auteurs : MANZIONE J., COLLIER S., MEMORY S., et al.


The US Army has conducted a second-generation design, fabrication, and test of a transcritical carbon dioxide cooling system on the M1114 up-armored High Mobility Multi-Purpose Wheeled Vehicle (HMMWV). The HMMWV cooling system is designed to cool military personnel and electronics equipment in hot ambient climates with rated conditions of 51.7°C outdoor ambient temperature. Carbon dioxide was selected as an alternate refrigerant because of its high potential for reduced logistics burden, cool-down performance, space and weight reductions, and environmental responsibility. During 2005-6, the US Army, in collaboration with Modine and the University of Illinois, has conducted breadboard testing, full-scale prototype fabrication, instrumented laboratory tests, and proving ground operational testing. This paper summarizes those development and testing results.
