Early middle ages. Aqueduct water diverted through certain

houses. Circulated through two layer walls. The earliest recorded air conditioning

system.

Roman Aqueduct Circulation

Developed in Han Dynasty.

Developed for Emperor Xuanzong, by Ding Huan.

3 meter wide, seven bladed fan.

Manually powered, likely by slaves.

Hand Dynasty Fan

Developed in the Middle East.

Developed during Medieval times.

Windows on top took in winds from above and funneled the cool air down into the lower buildings.

More efficient. Did not need any outsource energy such as water or man power. Only wind.

Wind Towers

Developed by Willis Havilland Carrier, ”Father of cool”.

Developed in 1902. Main purpose to let ink dry. Did not have to depend on the weather.

First Air Conditioning Machine

First air conditioning unit available for home use.

Large unit plugged into outlet.

Air conditioning no longer limited to commercial buildings.

Bulky.

Philco-York Air Conditioning Unit

Developed in 1947 Cheaply mass produced Innovated by Henry Gallison Saved space 43,000 sold in 1847

Window Air Conditioners

Kills airborne fungus and bacteria Small and Compact Cleans as well as cools the air.

Samsung Air conditioner

Effects on the environment could be negative from the mining for the raw materials in making them.

As the units became smaller, the effect became smaller.

Society improved from the innovations of air conditioning by allowing an improvement in worker morale.
