Question

Answer

Release of compressed gas
Air conditioning works by removing heat from a space and transferring it outside. This process is achieved through the use of a refrigerant, a substance that changes from a liquid to a gas and back again quickly and efficiently. The cooling by an air conditioner is primarily done by the release of compressed gas.

How does it work?
- The air conditioner absorbs heat from the indoor air, which causes the refrigerant to evaporate and turn into a gas.
- The gas is then compressed, which increases its temperature and pressure.
- The hot, compressed gas is then passed through a set of coils located outside the building, where it releases the heat to the outside air.
- As the gas releases heat, it condenses back into a liquid state.
- The liquid refrigerant then flows back inside the building, where it absorbs more heat and the cycle continues.

Importance of compressed gas
- The release of compressed gas is crucial in the cooling process as it allows the air conditioner to transfer heat effectively from inside to outside.
- By compressing the gas, the air conditioner is able to raise its temperature, making it easier to release the heat to the external environment.
In conclusion, the cooling by an air conditioner is primarily done by the release of compressed gas, which plays a vital role in the heat transfer process.
