#AncientEgyptian ‘#AirConditioning’ could help cool modern buildings

One research team hopes to harness 5,000-year-old ideas to battle rising temperatures.

"By retrofitting their shipping container test chamber with off-the-grid, solar powered battery storage, AL-Hassawi’s team can heat their chamber to upwards of 130 degrees Fahrenheit to test out their solutions while measuring factors such as air velocity, temperature, and humidity. The team is particularly focused on optimizing a passive cooling method involving large towers and evaporative cooling that dates as far back as 2,500 BCE in ancient Egypt. In these designs, moisture evaporates at the tower’s top, which turns into cool, heavier air that then sinks down to the habitable space below. In the team’s version, moisture could be generated via misting nozzles, shower heads, or simply water-soaked pads.

" 'It’s an older technology, but there’s been an attempt to innovate and use a mix of new and existing technologies to improve performance and the cooling capacity of these systems,' explained Al-Hassawi, who also envisions retrofitting smokestacks in older buildings to work as new cooling towers."

Ancient Egyptian ‘air conditioning’ could help cool modern buildings

Passive cooling systems are increasingly vital to a warming world. Here's how one research team hopes to harness ancient tech to do it.

I once read of a cooling method a lot like this, but with the air flow in reverse.

The towers are passively heated by the sun, drawing warm air up and out. Fresh air enters the building via underground tunnels, where water from the soil evaporates to provide cooling.

@BlueDot I posted something about how the #RiverSeine in France was used for cooling, along similar lines.
