Estimating Stress of Piping System Excited by Scroll Compressor

Scroll Compressor Analytical Model

The efficiency of the scroll compressor which employs the axial and the radial sealing techniques is competitive with that of the other rotary and the reciprocating compressors. The bearing load and the torque are smooth so that quiet operation is realized. 'l'herefore the machine is suitable particularly for air conditioning application. The authors have studied the scroll compressor which uti...

The Mechanical Analysis of a Scroll Compressor

Based on thermodynamic and mechanical models. the axial and tangential forces acting on the orbiting scroll and their balance methods are discussed in this paper. Besides, a detailed analysis of orbiting mechanism of three Pins is carried out too. INTRODUCTION The advantageous characteristics of scroll compressor have been pr1>ved in theory and experiment [ 1 ] [ 3 ] in rer.ent years. Remarking...

Development of High Performance 3D Scroll Compressor

This paper describes the efficiency improvement technology of the 3D scroll compressors and the development of 3D scroll compressor for commercial air-conditioner. 3D scroll, our newly developed profile, can compress refrigerant not only radially but also axially. Therefore, higher compression ratio, higher reliability and larger capacity are obtained by introducing 3D scroll. Since the 3D scro...

Development of Large Capacity CO2 Scroll Compressor

CO2 refrigerant with a high operating pressure has a large difference between the suction and discharge pressures in compressors. Because of a load increase, the high performance and high reliability of compressors are required. Compared to the scroll compressor employing the conventional refrigerant, the thrust load increases in the CO2 scroll compressor. Therefore the design of thrust bearing...
