Today, air conditioning units have become such an integral part of life that many people forget that there was a time when people didn’t have them. Thankfully for us, air conditioning units were invented, and we have them in our homes today.
The idea behind air conditioning units actually began as far back as second century China when Ding Huane invented the manually powered rotary fan. While it was a far cry from today’s air conditioning units, it sparked the idea that air could be cooled for comfort.
Hundreds of years later in 1758, Benjamin Franklin became very interested in the subject. He began experimenting with evaporation and alcohol to see how he could decrease the temperature of the air even further. He was able to obtain freezing temperatures with his tools and techniques.
The first of the modern air conditioning units wasn’t invented until the beginning of the twentieth century. In 1902, Willis Haviland Carrier began his own experiments. His idea was to send air through coils filled with cold water. He wasn’t trying to create air conditioning, only to solve a problem at a printing plant. Still, his idea was a good one, and it caught on.
Thirty years later, in 1933, air conditioning units were finally created for the purposes of human comfort. They were created by the Carrier Air Conditioning Company of America, and they contained a condensing unit, a blower, mechanical controls, and an evaporator coil. Finally, Americans had a workable model for creating a whole new line of air conditioning units.
While air conditioning units still work based on the same principles as the first air conditioning units did over a hundred years ago, they have made huge advances since then. Today’s models are more energy-efficient than ever, and the required standards rise every year. Today’s air conditioning units also have several new and improved features such as convenient temperature controls, timers, remote access and email alerts for ultimate homeowner comfort.
