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.
A scroll compressor, also known as scroll pump and scroll vacuum pump, uses two interleaved spiral-like vanes to pump or compress fluids such as liquids and gases. The vane geometry may be involute , archimedean spiral , or hybrid curves.
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.
In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.
The screw compressor was first patented in 1878 by Heinrich Krigar in Germany, however the patent expired without a working machine being built. [4] [5] The modern helical lobe screw compressor was developed in Sweden by Alf Lysholm who was the chief engineer at Ljungstroms Angturbin.
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 ...
