Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 th…
