Investigations on Force Characteristics of Orbiting Scroll in Asymmetricsuction Scroll Compressors

Recent Patents on Mechanical Engineering, 2022
Background: Scroll refrigeration compressors are the critical equipment for the refrigeration system in air conditioners and vehicles. The asymmetric suction structure can be applied to reduce the scroll compressors' size. However, the pressure difference between the symmetric working chambers becomes larger and leads to the special force ...
