Modeling and numerical simulation of the thermal and fluid dynamic behavior of hermetic reciprocating compressors. Part 2: experimental investigation.

An experimental validation of a mathematical model developed for the numerical simulation of the thermal and fluid dynamic behaviour of hermetic reciprocating compressors is presented. Details of the physical model and a critical analysis of the quality of the numerical solutions are presented in a companion paper (Part 1). Different compressor geometries have been tested considering a wide range of working conditions and refrigerant fluids. A complete description of the experimental equipment and its instrumentation is included here. Good agreement between numerical and experimental data has been obtained, generating a better understanding of the thermal and fluid dynamic behavior of these compressors.
