提出了一种新型的燃气埃里克森循环热泵的实现方案。该概念使用压缩机和膨胀机的液体溢流来接近等温压缩和膨胀过程。使用基于EES的计算机模型进行循环的热力学分析。在具有可逆部件的理想情况下，随着液泛的增加，冷却器的性能系数（COP）接近卡诺COP。然而，在非理想情况下，当旋转机械不可逆地操作时，存在产生最佳性能的最佳液体溢流速率和压力比。与所有气体循环一样，液泛式埃里克森循环冷却器的性能对压缩机和膨胀机的效率非常敏感。两个周期配置的结果。
A novel implementation of a gas Ericsson cycle heat pump is presented. The concept uses liquid flooding of the compressor and expander to approach isothermal compression and expansion processes. A thermodynamic analysis of the cycle was performed using an EES-based computer model. In the ideal case with reversible components, the coefficient of performance (COP) of the cooler approaches the Carnot COP as the liquid flooding is increased. However, in the nonideal case when the rotating machinery operates irreversibly, there is an optimal liquid flooding rate and pressure ratio that produces the best performance. As with all gas cycles, the performance of the liquid flooded Ericsson cycle cooler is very sensitive to the efficiency of the compressor and expander. Results for two cycle configurations are presented.
