跨临界CO_2循环中回热器研究进展概述
|
摘要
由于臭氧层破坏和全球变暖等原因,CO_2作为新型制冷工质在跨临界CO_2循环中被广泛推广和应用。在循环中加入回热器可大幅度提升系统性能,本文针对跨临界CO_2循环中的回热器应用,从带回热器的跨临界CO_2系统性能、回热器结构、回热器在系统循环中的位置、回热器效率以及回热器入口制冷剂温度等几个方面对系统性能的具体影响进行深入探讨,介绍了国内外研究进展,对回热器的应用加以分析和展望。
Due to the depletion of the ozone layer and the global climate warming,CO_2 is promoted and applied extensively in the transcritical CO_2 system as a new type of refrigerant. Adding the internal heat exchanger in the loop can sharply improve the performance of the system. This paper deeply discussed the specific effects on the performance of the system in the aspects of the performance of transcritical CO_2 system added with the internal heat exchanger,the structure of the internal heat exchanger,the location of the internal heat exchanger in the loop,the efficiency of the internal heat exchanger and the temperature of the refrigerant at inlet of the internal heat exchanger for the application of the internal heat exchanger in the transcritical CO_2 system. In addition,the progress in researches at home and abroad was introduced and the application of the internal heat exchanger was analyzed and prospected.
