Abstract:
1. A cooling system that uses a compression cycle for cooling a working fluid, comprising: a cool side heat exchanger for transferring heat QL from a heat load to the working fluid that heats the working fluid; a compressor driven by a prime mover that receives the heated working fluid and compresses it to a high pressure; a warm side heat exchanger that receives the heated high-pressure working fluid from the compressor and cools it with an expendable liquid that receives heat from the heated high pressure working fluid and vaporises it to produce a pressurised expendable gas; a turbine powered by the pressurised expendable gas that assists the prime mover to drive the compressor; an expendable storage tank for storing the expendable; and an expendable feed pump for transferring expendable from the expendable storage tank to the warm side heat exchanger.
