An aircraft cooling system includes a refrigerant cycle including a first heat exchanger. A liquid cycle passes a liquid through the first heat exchanger, at which it is cooled by a refrigerant in the refrigerant cycle. An air cycle compresses air and delivers the compressed air into a second heat exchanger. The liquid passes through the second heat exchanger at a location downstream of the first heat exchanger. The liquid cools the air in the second heat exchanger. Air downstream of the second heat exchanger passes to be utilized by a use on an aircraft.

1. An aircraft cooling system comprises: a refrigerant cycle, said refrigerant cycle including a first heat exchanger;a liquid cycle, said liquid cycle passing a liquid through said first heat exchanger, at which it is cooled by a refrigerant in the refrigerant cycle;an air cycle including a compressor for compressing air and delivering compressed air into a primary heat exchanger, and a fan to drive cooling air over said primary heat exchanger to cool the compressed air, the compressed air then being delivered into a second heat exchanger, and liquid passing through said second heat exchanger at a location downstream of said first heat exchanger, and the liquid for cooling the air in said second heat exchanger, air downstream of said second heat exchanger passing to be utilized by an air use on an aircraft;said air cycle includes a turbine downstream of said second heat exchanger, and air having been cooled in said second heat exchanger driving said turbine to expand the air, and at least partially power said compressor;a water extractor is positioned downstream of said second heat exchanger, and upstream of said turbine;a liquid supply line branches to at least two destinations downstream of said first heat exchanger, with one branch passing through said second heat exchanger, and another branch passing to a liquid use for cool liquid; andsaid air cycle includes a third heat exchanger downstream of said second heat exchanger, and a portion of the liquid which is not delivered to said second heat exchanger passing through said third heat exchanger prior to passing to the liquid use. 2. The aircraft cooling system of claim 1, wherein the air use is one of at least a portion of the air being delivered into a passenger cabin on an associated aircraft, or being used to cool a component on an associated aircraft. 3. A combined system for providing cooling fluids to an aircraft comprising: a vapor cycle, said vapor cycle including a condenser receiving a compressed refrigerant from a compressor, and an expansion device downstream of said condenser, refrigerant passing from said condenser to said expansion device and into an evaporator;a liquid cycle, said liquid cycle passing through said evaporator to be cooled by the refrigerant in said evaporator, a first portion of the liquid then passing to an air moisture condensing heat exchanger, and a second portion of the liquid branching to a liquid use, wherein the cooled liquid is utilized to cool components;an air cycle including a compressor receiving air from an outside source and compressing the air, the compressed air being delivered through a primary heat exchanger, wherein heat is exchanged from the compressed air to an outside environment by passing outside air over said primary heat exchanger, and air having passed through said primary heat exchanger passing through said air moisture condensing heat exchanger at which it is further cooled by the liquid, and air from said air moisture condensing heat exchanger then passing through a turbine to drive said turbine, and at least partially drive said compressor, air from said turbine passing to an enclosed space for use of a cooled air;said enclosed space includes providing air on an associated aircraft into a passenger cabin; andsaid second portion of liquid passing through an intermediate heat exchanger, and then to the liquid load, and air downstream of said turbine passing through said intermediate heat exchanger. 4. The aircraft cooling system of claim 2, wherein said air use includes at least a portion of the air being delivered into a passenger cabin.
