实验研究了反射式分流器在不同流量和不同安装角度工况下的分流特性，得到空气/水两相流体流量、安装角度对反射式分流器性能的影响规律。研究结果表明，反射式分流器的分流特性受安装角度影响小，在倾斜安装（0°~15°）时也具有较好分流性能；在0°~15°安装角度范围内，当两相流体流量增大时，分流性能变好，故其适合大流量的空调系统。结合理论分析和实验结果，提出反射式分流器改进结构的方案，通过 CFD 模拟，确定改进方案；并对改进后的结构进行实验，与改进前分流器性能进行对比，对比结果表明改进的分流器结构能够改善分流器的分流特性。

The flow distribution characteristics of reflect-type distributors under the conditions of different air/water two-phase flow rates and different installation angles were investigated experimentally, and the influence principle of two-phase flow rate and installation angle on the performance was obtained. The research results show that, the performance of reflect-type distributor is slightly affected by the installation angle, and is still good when the installation angle is within 0°~15°; as two-phase flow rate increases, the performance of reflect-type distributor becomes better, so the distributor is suitable for air conditioning system with large capacity. According to the theoretical analysis and experimental results, the structure of reflect-type distributor was improved by CFD simulation. The improvement effect was verified experimentally by comparing the performance of the optimized distributor with that of the original one, and the result shows that the performance of the optimized distributor is improved.
