According to one of the reports from the University of Berkeley, 700 million air conditioners will be installed in the world by 2030, and this figure will reach 1.6 billion by 2050. In terms of electricity consumption and greenhouse gas emissions, this is comparable to the emergence of several new countries in the world.
80% of air conditioners contain R22 freon, which contains hydrofluorocarbons (HFCs). According to scientists, this freon has a destructive effect on the ozone ball and contributes to global warming.
In order to reduce this effect, in 2016, 200 countries from all over the world signed agreements on the replacement of R22 freon with three-component freon 407 and two-component R 410a in the production of air conditioners.
To maximize the effect, researchers are exploring how to use a passive turbocharged cooling technology known as radiation cooling or sky cooling with sunscreen nonmaterials that radiate heat from the rooftops of buildings.
