Let’s take a walk back in time to remember those who invented the world we all live in now and maybe even thank them for the amazing invention of heating and cooling for the home or office! It is something most people take for granted but it has made the lives of everyone a lot better, especially in those southern weather conditions where the temps can get quite hot, the Heating and Air Conditioning program was invented in the early 19th century by American inventor Oliver Evans.
Evans’s system, which he called the “evaporative cooling system”, was first used in textile mills to control the temperature and humidity of the air. In 1881, English engineer Sir William Thomson (later Lord Kelvin) patented the thermostat, which he used to regulate the temperature of his oil heater. The first Heating and Air Conditioning systems using the thermostat were installed in factories and office buildings in the late 19th century. In 1902, American engineer Willis Carrier invented the AC unit, which he used to cool the air in a printing plant. The AC component quickly became popular for its ability to evenly cool large spaces. In 1925, Carrier introduced the first Heating and Air Conditioning program for residential use. The system, which he called the “heat pump”, was designed to both heat and cool homes. Today, Heating and Air Conditioning systems are used in a wide range of applications, from small homes to immense office buildings and industrial facilities, and heating and Air Conditioning systems are an essential part of modern life, and their invention has had a profound impact on our world. It is always wonderful to remember the heroes of the world.
