Note:
This paper presents a method for the numerical simulation of reciprocating compressors for household refrigeration. The compressor is regarded as a set of volumes and one-dimensional, variable-area ducts connected together. The model describes all relevant features of the compressor, including suction and discharge

mufflers and automatic valves. The equations governing the unsteady flow of a real gas in the ducts are numerically solved with a high order accurate discontinuous Galerkin method. The model accounts for the interaction between the gas flow and the automatic valves motion by solving the governing equations in a strictly coupled fashion. The method has been validated by comparing the numerical results obtained in the simulation of a compressor for household refrigeration with experimental data. The results show the potentialities offered by the proposed approach.
