Carrier’s new top-of-the line central air conditioner, the Infinity, is far different than the founder’s early models, featuring advanced components including a two-stage scroll compressor for quieter, more energy-efficient performance.Įnergy efficiency standards set by the U.S. Willis Haviland Carrier was an American engineer and inventor, and is known as the man who invented modern air conditioning.Today’s air conditioners, while operating on the same fundamental science as Carrier’s 1933 system, incorporate advancements in vapor compression, diagnostics and controls, electronic sensors, materials, and energy efficiency. In 1933, the Carrier Air Conditioning Company of America developed an air conditioner using a belt-driven condensing unit and associated blower, mechanical controls, and evaporator coil, and this device became the model in the growing U.S. Borrowing from the concepts of mechanical refrigeration established in earlier years, Carrier’s system sent air through coils filled with cold water, cooling the air while at the same time removing moisture to control room humidity.
The first modern air conditioner was invented in 1902 by Willis Haviland Carrier, a skilled engineer who began experimenting with the laws of humidity control to solve an application problem at a printing plant in Brooklyn, NY. Willis Carrier: The Father of the Air Conditioner The concept of air cooling also intrigued the great American inventor and statesman Benjamin Franklin, who in 1758 conducted experiments with evaporation and alcohol to attain freezing temperatures. In 2000, air conditioning/refrigeration was named among the 10 greatest mechanical engineering achievements of the 20th century, according to a survey of ASME members.Īir conditioning actually has roots in second century China, where an inventor named Ding Huane crafted a manually powered rotary fan. These comfort units that homeowners activate with the ease of flipping a switch are complex electromechanical systems, the end products of nearly a century of engineering development in cooling, thermodynamics, controls, and energy efficiency. As summer approaches, bringing with it soaring temperatures and unbearable humidity, millions of people will turn on that marvel of discovery and invention – the air conditioner.
