The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
cleanse the air; After several more years of refinement and field testing, on January 2, 1906, Carrier was granted U.S. patent 808,897 for an Apparatus for Treating Air, the world's first spray-type air conditioning equipment. It was designed to humidify or dehumidify air, heating water for the first function and cooling it for the second.
Then by allowing hot air to blow on the cloths it decreased the room temperature by 20 degrees Fahrenheit. The problem with this method was essentially the same problem Gorrie had. It required an enormous amount of ice to keep the room cooled continuously. Yet it was an important event in the history of air conditioning.
American Standard Companies Inc. was a manufacturer of heating, ventilation, and air conditioning (HVAC) systems, plumbing fixtures, and automotive parts.The company was formed in 1929 through the merger of the American Radiator Company and Standard Sanitary Manufacturing Company forming the American Radiator and Standard Sanitary Corporation.
Willis Carrier's invention of air conditioning in 1902 marked a pivotal moment in human history, transforming the way people interact with indoor spaces. Before his breakthrough, buildings were subject to the whims of nature, often becoming unbearably hot and humid during the summer months.
In 1908, the Carrier Air Conditioner Company of America was created as a subsidiary of the Buffalo Forge Company, with Willis Carrier as its vice president. [ 7 ] With the onset of World War I in late 1914, the Buffalo Forge Company, where Carrier had been employed for 12 years, decided to confine its activities entirely to manufacturing.
In addition to manufacturing room air conditioners, Frigidaire also provided the factory air conditioning systems for General Motors (GM) automobiles. From the 1950s through the 1970s, these units developed a reputation for providing powerful air conditioning systems on virtually all GM cars and trucks from the largest Cadillacs to the small ...
The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K). [1] It also lists important milestones in thermometry , thermodynamics , statistical physics and calorimetry , that were crucial in development of low temperature systems.
