  • 1. Air conditioners and refrigerators work the sameway. Instead of cooling just the small, insulatedspace inside of a refrigerator, an air conditionercools a room, a whole house, or an entirebusiness.Air conditioners use chemicals that easily convertfrom a gas to a liquid and back again. Thischemical is used to transfer heat from the airinside of a home to the outside air.
  • 2. The first modern air conditioning system wasdeveloped in 1902 by a young electrical engineernamed Willis Haviland Carrier. It was designed tosolve a humidity problem at the Sackett-WilhelmsLithographing and Publishing Company inBrooklyn, N.Y. Paper stock .
  • 3. An evaporator is a device used to turn the liquid form of a chemical into its gaseousform. The liquid is evaporated, or vaporized, into a gas. An evaporator is used in an air-conditioning system to allow a compressed cooling chemical, such as Freon or R-410A,to evaporate from liquid to gas while absorbing heat in the process.[1] It can also be usedto remove water or other liquids from mixtures. The process of evaporation is widelyused to concentrate foods and chemicals as well as salvagesolvents. In theconcentration process, the goal of evaporation is to vaporize most of the water from asolution which contains the desired product. In the case of desalination of sea water, thereverse purpose applies; evaporation removes the desirable drinking water from theundesired product, salt.
  • 4. An air conditioning condenser works in conjunction with an airconditioning compressor. The unit is powered on, and then therefrigerant--a chemical liquid that easily converts to gas--is circulatedto the compressor. The refrigerant is compressed, forcing therefrigerants molecules to become compacted. The refrigerant, thendevelops increased energy, which, in turn causes it to increase intemperature. As a result, the refrigerant changes into a gas form thatflows into the condenser.
  • 5. The standard definition for an AC Motor is an electric motor thatis driven by alternating current. The fundamental operation ofan AC Motor relies on the principles of magnetism. The simpleAC Motor contains a coil of wire and two fixed magnetssurrounding a shaft. When an electric (AC) charge is applied tothe coil of wire, it becomes an electromagnet, generating amagnetic field. Simply described, when the magnets interact,the shaft and the coil of wires begin to rotate, operating themotor.
