Animation of a spinning scroll compressor. Léon Creux first patented a scroll compressor in 1905 in France and the US. [2] Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively.
The scroll-type supercharger is a scroll compressor used as a positive displacement orbiting-spiral supercharger. It is a compromise between the more rugged rotating lobe, and the more efficient sliding vane type superchargers, and is considered to offer the highest potential in regard to efficiency, noise and pressure fluctuation.
The scroll machine was patented in 1905 by Creux. [1] However, the first industrial applications of scroll machines dated from the 1980s, with the introduction into the market of refrigerant scroll compressors. Today, the scroll compressor is a dominant technology in the HVAC& ;R industry.
A vapor compression chiller typically uses one of four types of compressor: Reciprocating compression, scroll compression, screw-driven compression, and centrifugal compression are all mechanical machines that can be powered by electric motors, steam, or gas turbines. Using electric motors in a semi-hermetic or hermetic configuration is the ...

In 1991, Robert Shaffer founded Air Squared Inc. in Cincinnati, Ohio [1] to license oil-free scroll compressors for medical device applications. [2] Air Squared's first patent was awarded in 1997 titled Scroll compressor having a tip seal. [3] In 2001, Air Squared Manufacturing Inc. was formed in Broomfield, Colorado. Operations were ...
