| Abstract: | The influences of oil return technology on the performance of flooded and falling-film water chiller （heat pump） unit are analyzed firstly. Then the influences of oil separation technology on the performance of chiller are described in detail, and the influences of refrigerant＇s oil content on the heat transfer performance are analyzed from the theoretical and practical perspectives. It is concluded that it is easier to reach the goals of improving unit operation efficiency and stability using oil separation technology than using oil return technology only. |
