Development Of Scroll Compressor With New Compliant Mechanism

Increased demand of energy saving, more-high efficiency compressor is required. For high-efficiency of scroll compressor, we must minimize leak-loss on the tip and thrust-mechanical loss of the Orbiting-Scroll’s thrust face. New-type scroll compressor has new parts “Compliant-Frame” that is compliant axially, in the back of the Orbiting-Scroll, and has two independent middle-pressure chambers located in the upper side and the lower side of Compliant-Frame. By optimizing the lower side chamber, Orbiting-Scroll contacts Fixed-Scroll softly and we could minimize leak-loss on the tip. By optimizing the upper side chamber, thrust load on Orbiting-Scroll is decreased and we could minimize thrust mechanical loss of the Orbiting-Scroll’s thrust face. As a result, this new-type scroll compressor gained around 14% improvement in COP.
