Like AC? Thank the printing industry.

It is #famouslyhot in Columbia (and everywhere) right now. Could you imagine if we didn’t have air conditioning? Willis Carrier invented the process of cooling air – the technology behind the modern day AC – all to improve conditions of the ink and paper in a printing company!

From Wiki: “Carrier’s invention controlled not only temperature but also humidity. Carrier used his knowledge of the heating of objects with steam and reversed the process. Instead of sending air through hot coils, he sent it through cold coils (ones filled with cold water). The air blowing over the cold coils cooled the air, and one could thereby control the amount of moisture the colder air could hold. In turn, the humidity in the room could be controlled. The low heat and humidity were to help maintain consistent paper dimensions and ink alignment.” AC not only improved the raw materials and production processes, but also increased productivity among employees.

100 years later – we are all thankful for the relief from the heat!
