An object oriented approach of the numerical simulation model for the thermal and fluid dynamic behavior of hermetic reciprocating compressors was previously presented (Damle, et al., 2008), describing the fluid flow resolution and its numerical verification, based on an updated version of the conservation equations resolution (continuity, momentum and energy) along the whole compressor domain in a sequential way (Pérez-Segarra, et al. 2003). In the present paper, not only a numerical verification is shown, but also an experimental validation is detailed, including to the object oriented code the heat transfer resolution between solid parts and its coupling with the fluid flow through compressor elements, in addition to kinematic and dynamic analysis of crankshaft vs. connecting rod mechanism. The present full object oriented numerical simulation program, together with a brief numerical verification is here presented, while a detailed experimental validation for different compressor capacities, fluid refrigerants and working fluids is also shown in order to assure the numerical results obtained and the possibilities offered by the new program.
