Very soon, a completely new type of refrigerators may appear in the world, which will work without freon and even without a compressor. Scientists from three countries (China, USA, Brazil) propose to use twisting and unwinding spirals instead.
Such spirals can be made of both metal and polyethylene, and even 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 have a positive impact on the consumption of electricity on a global scale. It turns out that from 20 to 30% of all electricity generated in the world is consumed by large household appliances, including refrigerators. Cooling devices of a new type, working on elastic spirals, will be able, albeit partially, but to reduce these economic costs.
But here it is not so much the economic aspect that is important, but security. After all, with such household appliances, humanity will be able to completely abandon the use of harmful, ozone-destroying refrigerant in an indispensable household appliance (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 high.
Of course, a new type of refrigerator is only at the first stages of development, and before creating a full-fledged device, scientists will still have to face many technical issues. But already now there is every reason to believe that the new refrigerator, according to the principle of operation, will be completely different from its predecessor, working on freon.
