The general adoption of the R-290 on the self-contained equipment will practically nullify the direct CO₂ emission (GWP=0,02) focusing all the efforts on the indirect emission due to the energy use.

Variable speed technology (VCC) provides relevant energy saving vs on-off compressors, by modulating the compressor's cooling capacity according to the heat load; however, part of the advantages are eroded by other energy-using components (fans, lights, heater...) and further improvements on the VCC COP and speed extension are transferred to the cabinets with an asymptotic trend of its energy consumption.

The case study here presented highlights the results of the Embraco solution aiming to improve the above situation: it shows the energy-saving maximiza ...
