Pressure Strength Test Requirements for Hermetic Refrigerant Compressor Housings Using Fatigue Analysis
نویسندگان
چکیده
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 caused some research into the present safety factor used for pressure testing of equipment. Could this factor be revised or could a new method be developed using fatigue analysis to permit the new refrigerants to be used with current designs?

Unsteady-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...

The burst strength of rotary compressor pressure vessel directly affects the safety. Therefore, it is mandatory to ensure the strength of the pressure vessel. Major factors that determine the burst pressure of pressure vessel are stress concentration around the suction and discharge hole as well as its shape and thickness. In this study, stress concentration of the pressure vessel is investigat...
متن کاملBending Fatigue Failures of Compressor Valve Reeds
Bending fatigue failures OI cantilever type suction valve reeds occurred under operating conditions in a semi-hermetic refrigerant compressor during field trials. The finite element method (FEM) was applied to predict both the static and dynamic displacements and the resultant stresses of the reeds. The dynamic stresses in the location of the fracture exceeded the fatigue limit of the reed stee...
متن کاملAn Improved Shape for Hermetic Compressor Housings
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...
