Air conditioning system 

Air conditioner is a device used to control the temperature of the room. Its used in cold countries.

The system use a refrigeration cycle, to keep the warm weather.

The system:

 

The system uses a copper tubes in the form of coils containing Refrigeration (The liquid uses) that can be easily evaporate to gas, and turn to liquid again. The condensing unit is outside the building and the other set (Evaporating system) is inside the building.

 The compressor compresses cool low-pressure gas into hot high pressure gas. 

As the gas then moves through the condenser outside the building, it cools down into a liquid. This liquid flows through the piping and passes through an expansion valve, causing it to evaporate into a cold low-pressure gas. 

As the liquid changes to gas and evaporates, it absorbs heat from the inside of the building. 

A fan blows air across metal fins that have been chilled as a result of the heating being absorbed.

 This cause the room to cool down. The gas then continues to the compressor to continue the cycle.
