Discharge and casing temperature: behavior of hermetic compressors in countries with a tropical climate. Ingeniería Mecánica [online]. 2022, vol.25, n.3, pp. 49-57.  Epub 20-Dic-2022.

Knowing the temperature of the discharge and casing of hermetic domestic refrigeration compressors that operate in tropical climate conditions, allows us to guarantee the correct operation and useful life of these equipment. This article presents the results of tests in secondary fluid calorimeter of the behavior of the temperature of the discharge and casing to hermetic compressors of three manufacturers. The tests were carried out before and after the life test, at different ambient temperatures, voltages, with and without subcooling. The results have shown that there are significant differences between the discharge and casing temperature values of hermetic compressors, for the ambient temperature range studied. The necessary search for greater efficiency in refrigeration systems leads to the fact that the information obtained could be used in the study of improvements for the design of compressors that perform in tropical climates.

Palabras clave : hermetic compressors; discharge temperature; shell temperature; tropical climate; domestic refrigerators.
