An Improved Shape for Hermetic Compressor Housings
نویسنده
چکیده
An improved acoustic design for a hermetic compressor shell has been developed. The entire shell'surface is described by a single mathematical expression which insures that there are no discontinuities in either the surface or its curvature. The curvature of the improved housing is maximized within the geometric constraints of the size of the interior pumping mechanism and the specified maximum outside dimensions. The resulting housing, in the case of a small refrigeration compressor, has natural frequenices about one octave higher than exist in conventional housings. These higher resonant frequencies coupled with proper acoustic design of the rest of the compressor can result in significantly lower sound power levels.

Development of Hermetic Carbon Dioxide Compressor
This study, which developed a laboratory prototype of a hermetic C02 compressor, was motivated by three primary factors. First, the C02 cycle is important because of global concern about ozone depletion and global wanning. Second, the leak tightness, efficiency, size and weight of hermetic motor-driven compressors make them preferable to open-type compressors for conventional residentiallcommer...
متن کاملPressure Strength Test Requirements for Hermetic Refrigerant Compressor Housings Using Fatigue Analysis
The introduction of new refrigerants into the marketplace to replace CFC's banned by the Montreal Protocol has generated new research, required a review of many refrigeration concepts, and has raised new safety issues. One aspect that required further study occurred because some of the new refrigerants have a higher working pressure in the refrigeration and air conditioning equipment. This caus...
متن کاملNumerical Study and Experimental Comparison of CO2 Reciprocating Compressors for Small Cooling and/or Freezing Capacity Applications
The present paper is a numerical and experimental comparative study of hermetic and semi-hermetic reciprocating compressors working with carbon dioxide as fluid refrigerant against the conventional R134a hermetic compressors. When cooling conditions for one-stage compressor type (i.e., evaporation temperatures between 7.2oC and –10oC) have been considered, the numerical and experimental results...
متن کاملUnsteady-State Analysis of the Compression Cycle of a Hermetic Reciprocating Compressor
In this work a previous steady-state model [1] of a hermetic reciprocating compressor has been improved using an unsteady-state analysis of the compression cycle which allows a direct computation of the heat, work and mass flow rates. The new model requires the geometry of the machine, refrigerant inlet temperature and pressure, vapour discharge pressure, electric and mechanical efficiencies as...
متن کاملDesign and Development of an Oilfree, Hermetic High Pressure Compressor
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...
