Metal fins increase the surface area of the heat ... Midea is exploring new refrigeration technologies, such as radiative cooling materials, that can lower temperature by radiating energy ...

Q. How do I clean my AC condenser unit without damaging the metal fins? A. Dirt and debris that clog the condenser’s coil fins can restrict air flow, causing your cooling system to waste energy.

“The hollow rectangular shape of [the] fins, with open ends, also provides the air flow channel, which can ultimately increase the cooling effect,” the researchers also explained. The new ...

Researchers from the Solar Energy Research Institute (SERI) at the Universiti Kebangsaan Malaysia have developed a new passive technology to keep solar panels cool. They claim their new tech can ...
