As summer approaches with unbearable humidity and soaring temperatures, many homeowners turn to that marvel of inventions and discovery, which is the air conditioner. Homeowners activate these units with the simplicity of flipping a switch to complex electromechanical systems, the products of close to a century of engineering development in thermodynamics, cooling, controls, and energy efficiency. Air conditioning has origins in the second century China, where Ding Huang, an inventor, developed a manually powered rotary fan. The idea of air-cooling intrigued the American inventor Benjamin Franklin, who conducted experiments with alcohol evaporation in 1978 to attain freezing temperatures.

The Evolution of Air Conditioning SystemWillis Carrier: The Brains behind the Air Conditioner

Willis Haviland Carrier invented the first contemporary air conditioner in 1902. He is an expert engineer who started experimenting with humidity regulator to solve an application issue at a printing plant in Brooklyn. Deriving from the concepts of mechanical developed in the earlier years, his system transferred air through coils full of cold water, cooling the air and removing moisture to control the humidity in the room. In 1933, the Carrier Air Conditioning institution of America made an air conditioner utilizing a belt-driven condensing system and associated blower, mechanical controls, as well as an evaporator coil, which grew to became the model in the developing U.S. air-cooling systems’ market.

Willis Haviland Carrier was an American inventor, engineer, and is known to be the man who invented the modern day air conditioning. Whereas contemporary air conditioners operate on the same basic science as Carrier’s 1933 units, they incorporate developments in the compression of vapor, electronic sensors, diagnostics and controls, materials as well as energy efficiency. Carrier’s new premium central air conditioner is very different from the founder’s early models, featuring progressive parts, including two-stage scroll compressors for quieter and more energy-efficient performance.

Energy Efficiency Principles Set By The U.S.

The Department of Energy is spearheading improvements in air-conditioning systems. In further efforts to minimize the amount of energy used, some air-conditioning unit manufacturers have started stretching the capabilities of the standard wall thermostat, creating sophisticated microprocessor-based control and diagnostic kits that automate the functioning of the compressor and airflow system. The ComfortLink II remote thermostat by Trane offers the homeowner the ability to adjust settings and functions on the air conditioner from web-enabled cell phones and off-site computers; ComfortLink would additionally send emails and text alerts on when you need to replace the filter or schedule for routine service inspections.

Currently, nearly 80% of households in America have the central air conditioners, according to the Energy Information Administration. Progressively growing from being a form luxury to a necessity and significantly contributed to the quality of life in the country and the industrialized world. On top of the obvious enjoyments and benefits of comfort cooling, the air conditioner transformed architectural design, allowing houses without porches and windowless office buildings. Air conditioning has also played a significant role in the migration patterns and the economic development of the United States, allowing many homeowners to live and work in areas known for their hot climates.
