General Overview of the Air Conditioner: How Does it Work?

The air conditioner is a blessing in the summer holidays throughout the hotter climates of the world.  It feels as though the AC gives out cold air to the people that need it.  But, how does it make cold air?

     The AC actually uses a chemical, which is also described as “condensable working fluid” because it can easily change its state in gas or liquid form.  This transferable state of the condensable working fluid serves to transfer the heat that is inside a room to the outside world.  There is a fan inside the air conditioners that comes into play during this process.  Three other components are also necessary: “a compressor, a condenser, and an evaporator.”  The working fluid must pass through each of these inbuilt systems in order to convert the air in the room from hot to cold (“Air Conditioners,” 2007).

     As the working fluid passes through the compressor, it changes its state and increases in temperature.  Leaving the compressor as a heated, “high pressure gas,” the working fluid moves into the condenser which serves to ultimately transfer the heat from the inside to the outside world by means of its “metal fins” (“Air Conditioners”).

     The working fluid changes it state once again, right through this transfer of air.  As a “high pressure liquid,” the chemical flows next into the evaporator, where it undergoes a change of state yet again.  This change of state is the last but not the least important state of the chemical.  It is during its time in the evaporator that the working fluid also changes the temperature of the air around the evaporator.  Returning next to the compressor, the process is begun one more time, and continues to repeat itself while the AC is on (“Air Conditioners”).
