This paper presents a new variant of the Revolving Vane (RV) compressor, suitable for applications that require high cooling capacity yet low pressure pulsation. By adding supplementary free sliding vanes into the original RV mechanism, the compressor produces multiple discharge cycles per revolution, and hence, it can be configured to produce high volumetric capacity with lower pressure pulsations which are expected to lower the discharge noise level. In this paper, the working principles and the theoretical modelling of the multi-vane RV compressor are presented. A functional prototype has been designed, fabricated, instrumented and tested at the industrial grade compressor performance test bench, using refrigerant R134a as the working fluid. The prototype has operated at 1000 to 2000 rpm and attained pressure ratios of 5.3. The prototype's mass flow rates and volumetric efficiency were successfully measured and correlated with the predictions from numerical simulations. Discrepancies between the predicted and the measured mass flow rates are within ±15%.

本文介绍了一种新型旋转叶片 (RV) 压缩机，适用于需要高冷却能力和低压脉动的应用。通过在原始 RV 机构中添加辅助自由滑动叶片，压缩机每转产生多个排放循环，因此，它可以配置为产生高容积容量和较低的压力脉动，从而降低排放噪音水平。在本文中，介绍了多叶片 RV 压缩机的工作原理和理论建模。使用制冷剂 R134a 作为工作流体，已经在工业级压缩机性能测试台上设计、制造、安装并测试了功能原型。该原型机以 1000 至 2000 rpm 的转速运行，压力比为 5.3。原型' s 质量流量和容积效率被成功测量并与数值模拟的预测相关联。预测和测量的质量流量之间的差异在 ±15% 以内。
