In the face of dangerous heat waves this summer, Americans have taken shelter in air-conditioned cooling centers. Normally, that would be a wise choice, but during a pandemic, indoor shelters present new risks. The same air conditioning systems that keep us cool recirculate air around us, potentially spreading the coronavirus.
“Air conditioners look like they’re bringing in air from the outside because they go through the window, but it is 100 percent recirculated air,” said Forrest Meggers, an assistant professor of architecture at Princeton University. “If you had a system that could cool without being focused solely on cooling air, then you could actually open your windows.”
Meggers and an international team of researchers have developed a safer way for people to beat the heat — a highly efficient cooling system that doesn’t move air around.
