Who invented the air conditioner in 1902

In the next wave of technology development, Ingersoll Rand and other manufacturers will advance smart technologies to interface their systems with the national electric grid, allowing units to be regulated according to geography and changing weather conditions.

Grid interoperability could push air-conditioning research down the pathway of fully variable speed systems, further reducing energy consumption. Air conditioning has grown from a luxury to a necessity and contributed in many ways to the quality of life in America and the industrialized world. In addition to the obvious benefits and enjoyments of comfort cooling, the air conditioner altered architectural design, allowing windowless office buildings and houses without porches.

Air conditioning also played a major role in migration patterns and economic development in the U. ASME Membership 1 year has been added to your cart. Throughout the next decade, scores of commercial businesses jumped on the air conditioning bandwagon, installing huge by modern standards and toxic they used ammonia as a coolant air conditioning devices in their stores. The addition of air conditioning allowed employee productivity to soar in the summer months, a time when workers frequently began losing their motivation due to sweltering temperatures.

The expansion of air conditioning into American homes was stalled during the Great Depression and World War II, but by the s, those who could afford it began adopting this modern convenience by the thousands. And while only 10 percent of American homes had air conditioning units in , this number continued to climb slowly and steadily as the decades rolled by.

By the year , 86 percent of homes had AC systems, according to the Carrier Corporation. Today, air conditioning units are considered standard equipment in U. The type of AC equipment varies across regions, however.

Central air systems are most common in the South, Midwest and West, while room conditioners are most common in the Northeast, according to the U. Widespread use of air conditioning eventually facilitated a long-term shift in the U. Prior to home AC units, cities in the desert, the Deep South and Florida had very little growth as most people couldn't handle the oppressive weather.

With the advent of home air conditioning, however, people were able to spread out and migrate to these formerly avoided areas. Advances in technology eventually yielded the more convenient window air conditioner in the late s, though it remained out of reach for most. The general public—those not privy to the few luxurious hotels and cars that used cooling systems early on—often first encountered air-conditioning in movie theaters, which started to widely use the technology in the s.

It was one of the few things proprietors sprung for during the Great Depression, and theaters were one of the rare places where the hoi polloi could enjoy chilly, artificial air.

Eventually, air conditioners lost their aura of luxury. Write to Mahita Gajanan at mahita. The first centrifugal refrigeration machine invented by Willis H. The Carrier Brand went on to be a leading brand in air conditioning and made enjoying Texas summers possible.

While Carrier invented the AC unit, we fix and install them for our customers. Although Willis Carrier is largely credited with inventing the modern air conditioner, Frederick Jones, an African-American, invented the first portable air conditioning unit.

His invention was used largely in field military hospitals keeping wounded soldiers comfortable while they recovered from injuries sustained while fighting. Jones had at least 60 patents on various inventions including refrigeration for food transport trucks.
