概述:本文介绍了一种新型的制冷和液化装置。在这种装置中,用一个膨肿喷射器代替了常用的焦耳——汤姆逊阀。采用了这种方法,就可以避免最低温度与压缩机进气压力之间的联系。这样,就可以提高进气压力,从而导致压缩机热交换器体积的减小和工作效率的提高。这里讨论了不同的使用情况所要求的喷射器效率。 Overview: This article describes a new type of refrigeration and liquefaction plant. In this device, a swollen ejector is used instead of the usual Joule-Thomson valve. With this approach, the link between minimum temperature and compressor inlet pressure can be avoided. In this way, it is possible to increase the intake pressure, resulting in a reduction in the volume of the compressor heat exchanger and an increase in work efficiency. The injector efficiency required for different uses is discussed here.
