Summary

In the design of hermetic compressors for household refrigeration, one important part of the overall efficiency of the machine comes from an optimized thermal efficiency of the discharge manifold. It is aimed that the heat generated during the compression process and heats up gas in the discharge chamber does not return to the compression chamber walls. Heating up the pump implies reducing the volumetric efficiency. Current technologies, like on/off and variable speed compressors, normally make use of metallic parts in the discharge chamber, such parts having high thermal conductivity coefficients, jeopardizing the compressor efficiency. Linear compressor technology, together with the absence of oil, allows the improvement of the discharge manifold system, increasing the thermal insulation of the heat from discharge chamber to the compression chamber, improving overall efficiency. This article aims to show the development of this improved discharge system, tests performed, and results obtained.
