Vane-type Compressors and Expanders with Minimal Internal Energy Losses

摘要: Current piston based air-conditioning system compressors only have isentropic efficiencies near 50%. Making internal leakage and friction negligible, via detailed design of the vane machine, would almost halve power consumption. In addition, by recovering expansion energy that is normally wasted an expander, Coefficient Performance COP can be improved up to additional 30%.
