Air cycle cooling machine.

摘要

A compact air cycle refrigeration system utilizes a three wheel air cycle cooling machine having a fan mounted between a turbine and compressor on a common drive shaft. The fan is positioned between two series-mounted heat exchangers mounted in a ram air duct and used to cool hot engine bleed air which drives the turbine. The turbine, in turn, drives the fan and the compressor, and the engine bleed air is directed, via the compressor, through the heat exchangers and into the turbine.
