High Performance Scroll Compressor With Liquid Refrigerant Injection

Improvement of compressor efficiency using the alternative refrigerant is demanded strongly to reduce CO2 emission, which causes the global warming. Especially the compressor using in frozen temperature level has long lifetime, and the correspondence to above-mentioned is one of the most important subjects. The scroll compressor is the promising structure to solve this problem. A technical poin...

Vibration Analysis of Refrigerant Compressor Shaft

An analysis of transverse vibrations of a compressor, using the modified Mykle stad-Prohl method which is one of the transfer matrix methods, is explained. A 10 hp four-cylinder refrigerant compressor was used as an object. The shaft and the frame are modeled as beams which are coupled with the sets of a spring and a damper that are the models of bearing oil film, bearing pedestals or the magne...

Experimental Performance Analysis of Reciprocating Compressor Working with Non-Aceotropic Refrigerant Mixtures

Unsteady State Analysis Of A Hermetic Reciprocating Compressor: Heat Transfer Inside the Cylinder And Valve Dynamics

In this work, an unsteady state analysis of the compression cycle of a small hermetic reciprocating compressor for domestic refrigeration was carried out. The mass and energy balances were applied to the refrigerant inside the cylinder in order to determine the mass and temperature behaviour through the compression process. A specific onedimensional model of the valves was developed to calculat...
