Compression enhanced ejector refrigeration cycle for low-grade heat utilization
暂无分享,去创建一个
The adaptation of conventional and improved ejector (vapor compressor) refrigeration cycles for low-grade or waste heat utilization is discussed. The improved ejector cycle is achieved by compression enhancement of the inlet to the ejector. Thus, a proper combination of mechanical and thermal energies provides a wide range of design alternatives which should yield a competitive refrigeration system when a heat source is available. An overview of the systems is provided, covering its principle of operation, expected performance, design, optimization, and control. Special attention is given to modification of conventional system components. Experimentation with the system demonstrated its trouble-free operation with the expected performance.<<ETX>>
