Nanoparticles can make home refrigeration more accessible for low-income households

Power consumption of a home refrigerator can be cut by 29% while improving cooling capacity. Researchers replaced environmentally-unfriendly R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotube (MWCNT) nanoparticles. Drop-in refrigerant replacement in the field by trained technicians is possible, says an engineer from the University of Johannesburg. This test of nanoparticle-dosed refrigerants is a first of its kind and can help make home refrigeration more accessible for vulnerable families.
