摘要
气体喷射器是一种利用制冷系统自身的高压气体源做动力,不消耗任何额外的其他能源的动力装置,在制冷系统中已经有大量的实际应用;利用数值模拟方法对制冷系统用喷射器的特征参数进行了实验研究,得出了最佳气体扩散角α和喉颈位置的实验值,对气体喷射器的设计研究有一定的参考价值。
The gas injector is a power device using high-pressure gas source from refrigerating system itself as the power, no consumption of any other extra energy, there has been a lot of practical application in the refrigeration system; This paper, by the experimental study using numerical simulation method on the characteristic parameters of the gas injector used for refrigeration system, obtained the optimum experimental value of the gas diffusion angle a and the throat neck location, have certain reference value for the design and research of gas injector.
