5、艺流程图上的液冷油冷却器，即压力容器图纸的油冷却器) 配经济器的系统中，从冷凝器或贮液器出来的液体，并不直接送节流阀节流，而是首先进入经济器冷却器中进一步冷却，出来后的液体工质的温度可下降数十度，制冷量将得到提高。经济器冷却器中液体的冷却，是依靠经辅助节流阀节流后进入经济器中的中压液体工质，它吸收高压液体工质的热量而蒸发，蒸发出来的中压气体被螺杆压缩机的中间补气口吸走（见流程图）。带经济器的机组特别适合取代双级活塞式机组，在较低蒸发温度下经济运行。压缩机的油分离系统 由于螺杆式制冷压缩机工作时喷入大量的润滑油与制冷剂蒸汽一起排出，所以在压缩机与冷凝器之间设置了高效的卧式油分离器。油分离器的作用

6、是分离压缩机排气中携带的润滑油，使进入冷凝器的制冷剂纯净，避免润滑油进入冷凝器而降低冷凝器的效率。油分离器还有贮油器的功能。本机组采用卧式油分离器，从压缩机排出的高压气体，通过排气管进入油分离器，降低流速，改变方向，向油分的另一端排去。在这个过程中，大量的润滑油因为惯性及重力的作用沉降到油分底部，剩余的含有微量冷冻机油的气体再通过油分滤芯，此微量冷冻机油被最后分离，通过油分离器底部的回油阀回到压缩机中，以确保挡油板之后的筒体底部尽量少存油。靠近油分离器出口的过滤芯采用的是高分子复合材料，油分离效果可达10ppm，当分油效果不够理想时可更换。油分离器附表一 R22饱和状态下的热力性质温度()绝对
