Summary

Trends in refrigeration market are forcing hermetic compressor manufacturers to increase the technical performance of their products as never before. New technologies are showing up as alternatives to face this challenge and help refrigeration compressor industry cope with this scenario. Among many possibilities electrically commanded valves is one that might be carefully studied and evaluated as a trend on refrigeration segment. This work studied analytical and experimentally the gas flow behavior along the discharge system of a serial hermetic compressor provided with an electrical commanded discharge valve. An incompressible unsteady viscous flow model was developed and applied to estimate gas pressures along discharge components in time domain. Experimental and calculated data were compared and presented good agreement in terms of absolute values and profiles, in spite of the relatively simple model employed.
