Summary

This paper shows the energy behavior of a chest-freezer of 7ft3 when is tested in different conditions of temperature and humidity which correspond of three geographical zones in Mexico: north, center and south. The refrigerant used is R516A which is evaluated like substitute of R134a which is the baseline refrigerant in the equipment. Results show an increase in the refrigerant mass of R516A respect to R134a in a 29.4%. Taking account of use of R516A, an increase in both COP as cooling capacity was found for climate conditions of center zone in comparison with north and south zones of 25.86% and 31.59% for the first parameter and 12.6% and 3.8% for the second. Finally, a reduction in specific compression work was got in the climate conditions of center zone being this of 15.3% and 29% respect to north and south zones.
