US Patent 10501191 Integrated aircraft cooling machine

An aircraft cooling machine is provided that includes a closed loop air cycle system and a vapor cycle system that both provide cooling aircraft loads. The closed loop air cycle system includes a compressor and a turbine and the vapor cycle system includes a compressor, condenser and an evaporator. A coupler is provided that pneumatically couples the turbine in the closed loop air cycle system to the compressor in the vapor cycle system via existing pneumatic power in the closed loop air cycle system.
