The conversion was carried out in 2021 and together with a new AC system has saved 56% in power consumption in the test store.
The Brazilian compressor manufacturer has calculated that its R290 and R600a compressors have saved the planet 1,568,025 metric tons of CO2 emissions since 2010.
Shifting towards natural refrigerants, especially R290, in the country’s room air conditioning sector, is key to reducing emissions, the report says.
The Eletrofrio system, which includes an R290 chiller and R290/glycol/R744 system, uses 3.5% less energy than an R134a system.
The company is also committed to improving the efficiency of its refrigerators between 10% and 25%, it said at K-CEP meeting.9
