Optimization of Geometry Dimensions and Modification of Calculation of Small-Scale Ejector for Solar Jet Refrigeration Based on Experiment

对小型太阳能喷射式制冷用喷射器进行了正交实验研究,得到了此类小型喷射器性能与各参数间的关系,确定了最优的主要结构参数,并认为最优的结构参数与索科洛夫的经典方法计算结果有一定差异.提出了基于实验数据的小型喷射器喷射系数的改进计算方法.

An orthogonal experimental study of small-scale ejectors that are used in solar jet refrigeration systems has been given. The relationship between various parameters and the performance of ejectors has been obtained based on the experiments. The optimization of geometry dimensions of ejectors is carried out, which reveals differences of the optimal geometry dimensions from those by Sokolov Method. Based on the experimental data an improvement in computing the entrainment ratio of such kind of solar ejectors is proposed.
