How does the Window Air Conditioner Works?

Air condition removes the warm air from your room by pumping the warm air outside. And while releasing the cool air into your room the air conditioner reduces the temperature of the air. Most of all it absorbs heat and releases cool air.

You maybe know how the refrigerator works. It absorbed heat in the room and releases cool air. The air conditioner works as same as the refrigerator.

How does the Window Air Conditioner Works

Step by step process of how portable mini window air conditioner works.

  • First of all, the warm/hot air drawn into a system
  • The warm air flows over a pipe inside and makes it cool
  • The warm air pumped outside with a pipe
  • Inside the air conditioner, it absorbs heat and reduces the temperature.
  • And then the cold air enters the room and mixes the cold air with the warm air inside the room. It reduces the total temperature of the room.
  • It also reduces humidity in that room.
  • This is how the air conditioner works
