Could these 3D printed bricks replace air conditioning?

These 3D printed bricks don’t look anything like an air conditioner, but that’s what they are. Provided, of course, that they’re wet and nature is allowed to do its thing.

The bricks are printed in such a way that they can function like a sponge. Their porous construction allows them to lock away water, which gets released later as evaporation takes place. That reduces the temperature of the bricks, and, theoretically, their surroundings.

The company behind Cool Bricks, Emerging Objects, based them on a passive refrigeration device that’s thousands of years old: the zeer pot. A zeer pot is actually a pair of terracotta pots — a larger one with a smaller one placed inside, with sand filling the gap between the two. The sand is then wet, and moisture is pulled through the porous terracotta as evaporation occurs.

Just how effective would these so-called Cool Bricks be? They wouldn’t do you any good in a place like Florida. The humidity is so high in the summer months that the bricks might just end up compounding your woes. Water they store wouldn’t evaporate and therefore wouldn’t help cool down your house.

In drier climates, they could certainly be effective — though for optimal results some very specific conditions are required. Assuming the Cool Brick does mimic the zeer pots that inspired their design, the humidity needs to hover between 10-30% and the temperature just a touch under 20° Celsius.

Another thing that helps increase the performance of a zeer pot is a bit of shade. That same shade can obviously have a major impact on the temperature of a structure on its own — in extreme cases, temperatures in the shade can be as much as 20° Celsius lower than in direct sun.

That’s why Cool Bricks might make a good choice for interior walls. With proper air flow, they ought to help keep rooms a bit cooler. You’d probably want to set up an eco-friendly water supply, too. You wouldn’t want to be wasting potable water keeping your Bricks moistened, not if you live in the kind of hot, dry climate where they’d make the most sense. Saving it for drinking might be a better move.
