Air - conditioning
Most people think that air conditioners lower the temperature in their homes simply by pumping cool air in. What ' s really happening is the warm air from your habitation is being removed and cycled back in as storeroom air. This cycle continues until your thermostat reaches the tailor-made temperature.
An air conditioner is fundamentally a refrigerator without an insulated box. It mainly uses the evaporation of a refrigerant, like Freon, to present cooling. The master mechanics of the Freon evaporation cycle are the similar in a refrigerator as in an air conditioner. According to the Merriam - Webster Dictionary Online, the term Freon is generically " used for any of changeable nonflammable fluorocarbons used as refrigerants and now propellants for aerosols. "
Diagram of the typical air conditioner.
This is how the evaporation cycle in an air conditioner works ( See How Refrigerators Work for complete details on this cycle ):
The compressor compresses cool Freon gas, causing undoubted to convert hot, high - pressure Freon gas ( pink in the diagram large ).
This hot gas runs through a set of coils so it can dissipate its fire, and it condenses into a fluid.The Freon fluid runs through an flowering valve, and in the process it evaporates to be reformed cold, blue - apprehension Freon facetious ( light blue in the diagram above ).
This cold gas runs through a set of coils that allow the gas to swallow heat and cool down the air inside the mansion.
Mixed in with the Freon is a small equivalent of lightweight oil. This oil is to lubricate the compressor.
Air conditioners help clean your home ' s air as husky. Most indoor units obtain filters that catch dust, pollen, mold spores and other allergens seeing well as smoke and everyday dirt found in the air. Most air conditioners and function whereas dehumidifiers. They catching excess water from the air and use positive to help cool the unit before getting rid of the water through a hose to the outside. Other units use the condensed wetness to improve effectiveness by routing the frozen water back into the system to be used again.
Whence this is the obscure concept involved in air conditioning. In the next section, we ' ll take a look at window and split - scheme units.
