Cold Air In Refrigerators
There are two physical processes of what occurs inside the refrigerator. When a liquid boils, it boils at a specific temperature based on the pressure that it’s under. The liquid will most likely stay at that same temperature until everything has evaporated. When a gas is compressed, the temperature and the pressure rises. If the gas is compressed enough, it will turn into a liquid. When the gas expands, the temperature and pressure falls.
In conclusion, the cold air that comes out of the refrigerator comes from a liquid that evaporates inside. Even though this fact is known from a refrigerator… the question is does the same process go through with an air conditioner.
