How does an AC reduce a rooms temperature?

Question

What does electricity do to remove heat from air?

In: 5

Answer 1

1. Compress a gas, making it extremely hot (Like 120-140 Degrees Fahrenheit)
2. Move the hot gas outside
3. Blow lots of outside air over the gas to cool it to ambient temperature (Removing energy from the system)
4. Let the gas expand rapidly, causing it to cool (Down to around 30 Degrees Fahrenheit) and become a liquid
5. Blow lots of room air over the liquid, cooling the air and warming the liquid until it evaporates (Adding energy back into the system while removing it from the room)

This all works because refrigerant has an extremely low boiling point (40-50 degrees Fahrenheit) and because compressing things adds energy which is released as heat, while allowing them to expand does the opposite.
