Very soon, completely new types of refrigerators may appear in the world that will work without freon and even without a compressor. Scientists from three countries (China, USA, Brazil) propose instead to use twisting and untwisting spirals.
Such spirals can be made of both metal and polyethylene, and even of household rubber. Scientists are confident that the efficiency of the new refrigerator will be significantly higher than the efficiency of a conventional cooling device. And this, in turn, will positively affect the consumption of electricity on a global scale. It turns out that from 20 to 30% of all the electricity that is generated in the world is consumed by large household appliances, including refrigerators. Cooling devices of a new type, operating on elastic spirals, will be able, albeit partially, to reduce these economic costs.
But here, it’s not so much the economic aspect that matters as security. Indeed, with such household appliances, mankind will be able to completely abandon the use of harmful, depleting the ozone layer, refrigerant in an indispensable device in a household (that is, in a refrigerator).
On a note! Modern refrigerants are safe for the planet and people, but the percentage of devices running on the "old" versions of Freon is still large.
Of course, a new type of refrigerator is only in the first stages of development, and before creating a full-fledged device, scientists still have to deal with many technical issues. But now there is every reason to believe that the new refrigerator, by the principle of operation, will be completely unlike its predecessor, working on freon.
