An air conditioning system for vehicles having a reverse Brayton cycle cooling system with a turbine drive for the rotor in the reverse Brayton cycle cooling system. A binary working fluid is used in the air conditioning system with air used in the reverse Brayton cycle cooling system. Waste heat is used to provide superheated water vapor for driving the turbine with the turbine return supplied to the air flow at the outlet of the compressor of the cooling system. The combined working fluid is supplied to a heat rejection heat exchanger where the excess water vapor is condensed and returned to the waste heat recovery system.
