Integrated Cooling System
One refrigerant architecture serving propulsion, power electronics, energy storage and passenger environments.
Cooling integrated
across the vehicle.
AALT uses environmentally responsible refrigerants to maintain key systems below atmospheric temperature and sustain high system efficiency after extensively assessing water-cooling approaches.
Actuators, generators, small batteries, power electronics and passenger compartments are cooled as one coordinated system, reducing the refrigeration power required by separate thermal loops.
R-134a, R-1234yf, R-600a, R-290 and R-744 have been tested. Current work uses R-1234yf in hot environments and R-744 in cold environments, while R-290 is being studied alongside isolation strategies for actuators, electronics and batteries.
Designed around the complete thermal path.
Each configuration balances low target temperature and minimum cooling-power consumption while maintaining vapour refrigerant at the outlet without dry-out.
