Scientists have developed new cooling panels to help fight the summer heat
An international team of researchers has developed a system of rectangular cooling panels that are powered by heat from the human body..
Many people cope with the heat in summer with air conditioners, which, in addition to consuming electricity, can harm their health and cause breathing problems. A group of scientists from several universities in the USA and Singapore have proposed a better alternative called Cold Tube..
In fact, they created a system of rectangular wall or ceiling panels that are cooled by circulating chilled water. Due to the absorption of naturally released heat from the body of a person nearby, the water in them moves from a heated to a colder surface, thus removing the captured energy. This creates a cooling sensation, as if cold air was blowing over the body, even if the temperature inside is high enough..
Similar panels have been used for quite some time in the construction industry, but the uniqueness of the new system lies in the fact that it does not require an additional dehumidification system. This is achieved thanks to a special airtight, moisture-repelling membrane that covers the cooled panels and prevents condensation, but allows infrared radiation to pass through..
According to the developers, the panels work regardless of the temperature and humidity of the air, so they can be used not only indoors, but also outdoors, for example, at public transport stops, fairs, concerts..
We also previously reported on the development of a new passive cooling system that helps fight heat in megacities without electricity..
