The Design of a Small Oil-Flooded Rotary Air Compressor

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 fe...

Oil Circulation Rate in Rotary Compressor: Its Measurement and Factors Affecting the Rate

Oil circulation rate is a crucial factor affecting air-conditioning system performance and rotary compressor reliability. This paper illustrates several design concepts to reduce oil circulation rate and discusses their effectiveness. This paper also discusses how to measure the rate in terms of accuracy and repeatability with a statistical significance.

Economics of water injected air screw compressor systems

There is a growing need for compressed air free of entrained oil to be used in industry. In many cases it can be supplied by oil flooded screw compressors with multi stage filtration systems, or by oil free screw compressors. However, if water injected screw compressors can be made to operate reliably, they could be more efficient and therefore cheaper to operate. Unfortunately, to date, such m...
