Your air conditioning unit is really an exceptional machine. However, the idea of cooling air in the interior of our building in order to improve our comfort by removing heat and moisture from the air has been around for a long time. Since prehistoric times, ice and snow were brought indoors for this purpose and ice harvesting, or the process where ice was stored for use in the summer, has been around since the late 17th century.
The ancient Egyptians used a very similar process to modern air conditioning. They hung reed plants in the windows, which they then poured water down. As the hot desert air in Egypt evaporated the water, the wind would blow and push the cooler air from the evaporation process into homes. This also would humidify the air, which can be beneficial to people’s health, especially when you’re sick. The Chinese were using fans since the beginning of the 2nd century AD.
As technology continued to build, so too did the air conditioning process. Evaporation was the main source of cooled air throughout the 17th and 18th centuries. However, it wasn’t until 1902 that the first modern air conditioner was invented in the United States. The breakthrough was simple really, looking back on it. Instead of sending air through hot coils, air was sent through cold coils instead. This process cooled the air and allowed the moisture content in the air to be controlled — which ironically was the whole reason for this invention.

THE MAIN COMPONENTS OF AIR CONDITIONING
Your modern air conditioner uses chemicals (most likely Freon) to cool your air. Your AC unit converts gas to a liquid and then back again, which then transfers hot air out of your home. There are three main components of your air conditioning unit. They are the compressor, condenser, and the evaporator.
- Compressor. Located on the outside of your home, the compressor takes the refrigerant that enters as a gas. As you may have guessed by its name, the compressor then takes this gas and squeezes it, raising its temperature and energy. This hot gas next moves to the condenser. The outside of your air conditioning unit has what appears to be metal fins on it. The sole purpose of these is to get rid of the heat from the inside of your AC unit more quickly.
- Condenser. Again, the name of the condenser describes what goes on in this component of your air conditioning unit. The gas is condensed into a liquid and is much cooler, and then makes its way to the evaporator.
- Evaporator. The fluid from the condenser is forced through a tiny opening into the evaporator. This small space causes the fluid’s pressure to drop. The fluid then begins to evaporate back into a gas, which removes the heat from the surrounding air. The heat is what separates the molecules so it can become gas again. The metal fins also contribute to this process. The refrigerant leaves the evaporator as a low-pressure, chilled gas, travels back to the compressor to repeat this process all over again. A fan connected to the evaporator is what distributes this cooled air into your home. The ductwork is the delivery system, both bringing in cool air from your AC unit and transferring hot air from your home to the AC unit to be cooled.
- Thermostat. The thermostat is the brain of this operation. It’s whole job is to sense the temperature of the surrounding air. When the air temperature reaches the set temperature, the thermostat switches your AC unit off. When the thermostat senses a rise in temperature, it switches the air conditioning back on. All of this happens without you having to think about it.
Air conditioning is a great invention of the Industrial Age. It keeps us cool during the hot summer months and helps to prevent heat stroke from excessively hot temperatures, which can lead to deaths.
