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, and it is something many people take for granted but it has made the lives of most people a lot better, especially in those southern climates where the temps can get quite toasty, but the Heating and A/C system 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 A/C 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 equipment abruptly became popular for its ability to evenly cool large spaces. In 1925, Carrier introduced the first Heating and A/C system for residential use. The system, which he called the “heat pump”, was designed to both heat and cool homes. Today, Heating and A/C systems are used in a wide range of applications, from small homes to large office buildings and industrial facilities, then heating and A/C systems are an essential part of modern life, and their invention has had a profound impact on our world. It is always good to remember the heroes of the world.
