The History of Air Conditioning

October 7, 2019 |

Imagine your life without air conditioning. It’s pretty hard, right? Would you even live where you live now without it? Probably not. Air conditioning is a luxury we’ve all come to realize we don’t want to live without. We have chemistry, countless engineers, and modern technology to thank for keeping us cool during these hot summers.

The first air conditioners were said to have dated back to ancient Egypt, where reeds were hung in windows and moistened with trickling water. The evaporation of the water cooled the air blowing through the window. Systems like these, called evaporative cooling, were used and developed all over the world until the early 19th century.

Modern air conditioning emerged from advances in chemistry during the early 19th century. The first large-scale electrical air conditioning was invented in 1902 by Willis Carrier, controlling not only the air’s temperature but also humidity. He used his knowledge of heating objects with steam and reversed the process. Instead of sending air through hot coils, he sent it through cold coils filled with cold water. This process, however, was not aimed at human comfort, it was designed to control humidity in the printing plant where he worked.

The look of modern air conditioners has changed quite a bit over time. When they were first introduced in homes in the late 1920s to the early 1930s, they were big and bulky and the size of furniture.

Until 1931, when the first window unit A/C was invented by H.H. Schultz and J.Q. Sherman.

The 1960s and 1970s saw the innovation of central A/C, which removed the window units for ductwork, evaporators, compressors, and fans. 

Today, HVAC innovations combine comfort and energy efficiency through variable speed motors, smart thermostats, and zoned comfort.
