2. Kaeser Compressors - Wikipedia

   en.wikipedia.org/wiki/Kaeser_Compressors

   The company grew rapidly after turning out its first reciprocating compressor in 1948, and by 1960 had outgrown its facility of 38 years and moved to a new location in Coburg, Germany. Under the leadership of Carl Kaeser, Jr., Kaeser engineers developed a rotary screw compressor that featured the "Sigma Profile" air-end in the early 1970s. The ...

3. Rotary-screw compressor - Wikipedia

   en.wikipedia.org/wiki/Rotary-screw_compressor

   The modern helical lobe screw compressor was developed in Sweden by Alf Lysholm who was the chief engineer at Ljungstroms Angturbin. Lysholm developed the screw compressor while looking for a way to overcome compressor surge in gas turbines. Lysholm first considered a roots type blower but found this was unable to generate a high enough ...

4. Scroll compressor - Wikipedia

   en.wikipedia.org/wiki/Scroll_compressor

   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.

5. Thermal expansion valve - Wikipedia

   en.wikipedia.org/wiki/Thermal_expansion_valve

   The refrigerant is compressed by the compressor to a high-pressure and high-temperature gaseous state. The high-pressure and high-temperature gas then enters the condenser. The condenser cools the high-pressure and high-temperature gas allowing it to condense to a high-pressure liquid by transferring heat to a lower temperature medium, usually ...

6. Compressor characteristic - Wikipedia

   en.wikipedia.org/wiki/Compressor_characteristic

   Surging takes place when compressor is operated off the design point and it affects the whole machine and this is aerodynamically and mechanically undesirable. It can damage the rotor bearings, rotor seals, compressor driver and affect the whole cycle operation. It results in high temperature, high vibration and leads to flow reversal. [4] [11 ...
