摘要
分析了螺杆式制冷机回油方法的缺陷 ,提出了利用平衡油泵进出口压力和平衡蒸发器与油泵及其进口管路温度的改进方法。实践证明改进方法回油效果良好。
Analyses the defect of oil recycle method for screw refrigerating machines, presents an improved method by balancing pressure between exits and entrances of oil pumps, balancing temperature between evaporators and pumps and balancing temperature between evaporators and entrance piping of pumps. The improved method is proved satisfying.
