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...

In the design of the small hermetic compressor, the forces acting on the compressor shell are important parameters to study for noise and vibration control. However, the input forces to the shell cannot be measured directly. In this paper, random force spectra on compressor shell has been measured indirectly with in-situ · vibration responses and system information. Three existing techniques of...

Abstract When ensuring the normative limit of heat gas transmitted to main pipelines by means air cooling devices transmission compressor station, modes parallel operation fan motors device system are considered. At same time, a comparison was made methods for adapting factors affecting energy-efficient operating modes. As result, based on mathematical model combustion mode through gas-air devi...

This paper describes the concept and the design features of a new, oilfree, reciprocating high pressure compressor for technical gases. The compressor is unique in concept and design, and introduces various new design elements. A magnetic coupling makes the compressor hermetic and allows inlet pressures of up to 16 bar. A new kind of clearance seal in the high-pressure stages allows reliable oi...

The application of carbon dioxide as natural refrigerant in commercial refrigeration systems has attracted higher interest in recent years for its promising energy efficiency and ecological sustainability. This paper presented the development of a low side scroll compressor for the bottle cooler application in the trans-critical cycle. Experimental tests were performed in two different temperat...

A new type of compression mechanism named "Helical Compressor'' was presented at the Purdue Conference in 1992 and 1998 [Refs.1-2]. There they showed the design, performance of the prototype, theoretical analysis, and its potential. After that fundamental experiment and theoretical analysis have . clarified various phenomenon in the Helical Compressor. As a result, we can successfully achieve t...

This paper describes a new design of low power 3-2 compressor circuit for high speed multipliers. Power consumption of proposed 3-2 compressor circuit varies from 0.355 nW to 1.6964 nW and delay varies from 2.0390 ns to 2.0224 ns. Further, power delay product of proposed circuit varies from 7.23×10 -18 (J) to 34.30×10 -18 (J) with varying supply voltage from 1.8V to 3.3V. The proposed compresso...

Tris paper, through analy3is to the specific power of the compressor, indicates that to reduce the power loss caused by friction is an important way to reduce the specific power of the compressor, investigates the realizability employing a single piston ring or a piston ring with small elasticity in the high speed double acting compressor, and raises a standpoint for a high speed double acting ...
