What is an Air conditioner and how does it works?
An air conditioner is a device that removes heat from a given space by the process of air cooling. Air conditioners can either cool the air or remove heat from the inside of a building to make it more comfortable for people inside. The refrigeration cycle is responsible for removing heat from the air and transferring it to water, which then transfers it to an outside condenser unit, where it is converted back into liquid form. The liquid refrigerant is then pumped through coils in an evaporator in order to cool down the air and remove heat from a given space. Air cooling by the natural process of evaporation is the oldest and simplest method, and was in use as long as 7000 years ago.
The first naturally occurring air conditioning systems were called "abundant" or "natural" air conditioners. These sometimes consisted of a shallow pool filled with water and mud, which would be covered in grass or some other vegetation. This would trap heat in the pool during the day and release it at night. More modern air conditioning systems involve using refrigerants to extract heat from a given space rather than relying on natural processes. Air conditioners are used as a cooling or heating system in buildings and vehicles, but they can also be installed outdoors to cool swimming pools, greenhouses, and other structures. The first crude, inefficient air conditioners were developed in the late 1800s, but it was not until the 1890s that they were successfully used. .The U.S. military uses mobile air conditioners to cool munitions during transport and storage. .The initial central air conditioning system was invented in 1902 by Willis Haviland Carrier. Carrier won the first patent for his invention on August 10, 1902, under patent no. 841,393 titled "Apparatus for Treating Air." By around 1906-1907 this invention was being sold and installed in New York City buildings including the Flatiron Building.
Nowadays air conditioners not only cool but also perform different functions such as air purification, humidity control and other things.
