A Hermetic Scroll Compressor For Application To High Heat Of Compression Gases

A horizontal hermetic scroll compressor has been developed for applications with high heatof-compression gases, including natural gas, air and helium (cryogenics). The compressor is a low profile horizontal design with oil-flooded cooling of the compression process. Combined with components required for oil separation and cooling, this design provides a smooth, continuous compression process featuring low noise and vibration, and performance comparable to other commercial oil flooded designs such as screw and rotary vane. The design approach allows the use of a production air conditioning compressor as the baseline model from which modifications are made for each specific use. Compressor operating characteristics and performance are discussed for each application.
