Review of Simple Mathematical Models of Valves in Reciprocating Compressors

Heat Transfer and Fluid Flow Considerations in Automatic Valves of Reciprocating Compressors

Several aspects related to fluid flow and heat transfer in reed type valves of reciprocating compressors are explored in the present work. Both n~erical and experimental results for pressure distributions along the valve in laminar and turbulent flows and results for heat transfer from the valve walls are presented and discussed. The presence of hydrodynamic instabilities related to self-sustai...

Innovation in Reciprocating Compressors by Technology Transfer From Modern Combustion Engines

In the paper the weak points of today's reciprocating compressors arc described. Referring to latest internal combustion engine technologies and improvements, some possible application on reciprocating compressors will be described and discussed as: • Application of advanced Electromechanical Valves (EMV) with fully variable valve actuation in order to increase compressor speed ("downsizing") a...

Accurate Experimental Determination of Frequencies, Mode Shapes, and Dynamic Strains in Plate Valves of Reciprocating Compressors

Study of Pneumatic Damping Behaviour for Reciprocating Compressorâ•Žs Valves

Based on the theoretical analysis and experimental study of pneumatic damping behaviour for the valves in the reciprocating compressor, this paper presents a simple mathematical model of pneumatic damping valves, in which the non-viscous damping force is introduced. The non-viscous damping coefficient is obtained by the experimental determination. The simulation results of this simple model for...

An Investigation on Reciprocating and Rotary Refrigeration Compressors

Besides reciprocating compressors which are the traditional working machines in refrigeration cycles a growing number of different types of rotary compressors is used especially for air conditioning purposes. In an experimental investigation various reciprocating and rotary compressors were ana lysed concerning their thermodynamic and mechanical losses. The compressors investigated are all near...
