Vibration reduction of a single cylinder reciprocating compressor based on multi-stage balancing

A Numerical Investigation on the Unstable Flow in a Single Stage of an Axial Compressor

An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters to improve the order of accuracy and the two-layer Baldwin-Lomax turbulence model was also implemented. Two test cases were prepared to validate the solver. The computed results were compared with the e...

Noise Reduction Analysis on Inverter Driven Two-Cylinder Rotary Compressor

Sanyo has originally introduced 6HP two-cylinder rotary compressors for packaged airconditioners in I 985. The concept of two-cylinder rotary compressor has been recently applied to room airconditioners(RACs) for the purpose of reducing vibration and noise of the unit. However. RACs are demanded to decrease the noise by lowering levels of the compressor noise. SanYo has newly developed the quie...

EER Improvement on a Reciprocating Hermetic Compressor

Experimental Study on Property of Oil-Flooded Rolling Cylinder Reciprocating Compressor

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...
