TY - EJOU AU - Prater, G. AU - Jr., TI - Computer Modeling and Simulation of Stationary-Vane, Rolling Piston Refrigeration Compressors T2 - Computer Modeling in Engineering \& Sciences PY - 2002 VL - 3 IS - 3 SN - 1526-1506 AB - A vapor compressor's performance is affected by pressure and mass flow fluctuations resulting from acoustic effects in the suction and discharge manifolds. Through proper geometric design of the manifolds, these pulsations can be modified to increase efficiency and reduce noise. This paper documents the development of a computer simulation program used to tune stationary-vane refrigeration compressors. The program models the mechanical, fluid, thermodynamic, kinematic, and acoustical processes occurring in such compressors, and calculates suction and discharge chamber pressures, mass flow rates, valve displacements, and acoustic input and transfer impedances. Experimental acoustic pressure measurements from a refrigerator test stand provide validation of the simulation results.
