流体喷射式齿轮压缩机在多温制冷循环中的应用研究

Application and Investigation of Ejecting Fluid Gear Compressor on Multi-stage Temperature Refrigeration Cycle

提出了一个新的多温制冷循环—流体喷射式齿轮压缩机多温制冷循环。在工作原理、特点、性能等方面与目前广为应用的采用蒸发压力调节阀的传统制冷循环进行了对比性分析和计算,结果表明,新循环理论功耗和冷凝器单位热负荷显著降低、制冷系数可提高10%、单位容积制冷量略有提高。

In the present paper, a new multi - stage temperature refrigeration cycle basing on ejecting fluid gear compressor is studied theoretically. The performance of the new cycle is compared with the traditional cycle which based on pressure regulator valve. The results show that the work consumption and the condensation load of the new cycle are decreased significantly.the refrigeration efficiency of the new cycle is increased by 10% than the traditional cycle.
