Especially in a large part of our country, living without air conditioners in the summer months affects the quality of life quite negatively. On the other hand, turning on the air conditioners also negatively affects our electricity bills. Since the air conditioners do not work without electricity, we are in a stalemate. MIT researchers seem to change this situation.
The newly developed method focuses on radiation and evaporation and does not use electricity. MIT’s system, called the passive cooling system, can be used to keep food fresher longer or to provide air conditioning in buildings. In the meantime, it will not allow our electricity bills to inflate.
It can be a new alternative to air conditioning.
Air conditioners, which draw attention with their electricity consumption, also cause the spread of gases that increase global warming. In addition, they put an additional load on existing power lines and become completely dysfunctional for regions with no or insufficient electricity infrastructure. The passive cooling system of Massachusetts Institute of Technology (MIT) researchers becomes an alternative at this point.
The cooling system, in which radiative cooling, evaporative cooling and thermal insulation techniques are used, is not much different from solar panels in appearance. On the other hand, in the tests, the developed systems can cool the ambient temperature up to 9.3 degrees. This allows food to be preserved for longer, even in hot climates.
In the article published in the journal Cell Reports Physical Science, the researchers state that such a system will at some point become an alternative for air conditioning and cooling, especially in parts of the world that do not have access to electricity and water.
The new system will play an important role both in food preservation and in reducing the burden on air conditioning systems. The three-layer system cools the water or air passing through it and transmits it. While the system can be used for surfaces in cabinets, it also needs a small amount of water for its maintenance.
