Researchers at Johns Hopkins University in the United States have developed a new material that makes obsolete air conditioners – with positive environmental implications.
A team of US researchers took a significant step in the field of energy efficiency By presenting a new material capable of reducing electrical consumption and improving performance in the face of traditional air conditioning systems.
The technology, based on semiconductors, was developed at the Johns Hopkins University Applied Physics Laboratory (APL), and could replace the current devices of air conditioningthanks to its ability to cool twice and spend only half.
The new system, known as CHESSwas presented in a recently published in the journal Nature.
Unlike conventional systems, the Chess No fans Not compressors, as it directly uses electricity to move the heat which makes it more compact, silent and friendly with the environment.
Laboratory tests conducted by the investigators team showed that the chess not only doubles the cooling capacity Compared to other thermoelectric materials, as well as a minimum amount of the new component to work – which makes its industrial production a large scale and would contribute to its economic viability.
The new material was developed with the collaboration of Samsung, which allowed the realization of tests in a real context as Housing and Work Spaces.
“This demonstration in the real world of refrigeration using new thermoelectric materials shows the capabilities of Nano-Película Chess,” he said Rama VenkatasubramanianAPL researcher and main author of the article that presented the new material, in Da Johns Hopkins.
“Marks a significant leap in cooling technology and prepares the terrain to translate advances into thermoelectric materials into practical, large -scale and energetically efficient refrigeration applications.”
The results confirm that this material can maintain optimal performance in daily situations without losing energy efficiency no refrigeration capacity.
In addition to its use in domestic climatization, technology could apply to sectors such as medicine, portable electronics or electric vehicles. Its ability to generate electricity from heat, including the human body, would allow feed small devices no need for traditional batteries.
It is also foreseen its usefulness in extreme contexts such as spacewhere compact and efficient solutions are required to manage temperatures.
“The success of this collaborative effort demonstrates that high -efficiency solid state refrigeration is not only scientifically viable, but also made of scale,” he said Susan honestAPL technology marketing manager.
“We hope to continue research and transferring technology with companies while we work to translate these innovations into real -world practical applications,” concludes Ehrlich.
