Willis Haviland Carrier (November 26, 1876 – October 7, 1950) was an American engineer, best known for inventing modern air conditioning.Carrier invented the first electrical air conditioning unit in 1902.
David N. Crosthwait Jr. (May 27, 1898 – February 25, 1976) was an African-American mechanical and electrical engineer, inventor, and writer.Crosthwait's expertise was on air ventilation, central air conditioning, and heat transfer systems.
An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space. [51] Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs. At the same time, the fan is slowed to reduce the evaporator temperature and condense more water.
A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators.
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required.

Parker's invention was further improved in 1935 by scientists who created forced convection wall heaters that use a coal furnace, electric fan, and ductwork throughout a home. Nowadays, homes utilize thermostats and forced air furnaces which can be attributed to Parker's design and invention of the central heating furnace.
However, before air conditioning existed, people had to be creative when trying to stay comfortable in sweltering conditions. ... 5 ways people stayed cool before air conditioning was invented ...
Reuben's invention of the convector radiator in 1923, which replaced the heavy, bulky, cast-iron radiators that prevailed at the time, was a major success. Trane's first air conditioning unit was developed in 1931. In 1982, Trane purchased General Electric's Central Air Conditioning Division.
