Do you think air conditioners lower the temperature in your home by pumping cool air in?
Actually the warm air from your home is being removed and cycled back in as cooler air. This cycle continues until your thermostat reaches the desired temperature. An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The Freon evaporation process is the same in a refrigerator as in an air conditioner.
This is how the evaporation cycle in an air conditioner works:
1.The compressor compresses cool Freon gas, causing it to become hot, high-pressure Freon gas.
2.This hot gas runs through a set of coils so it can dissipate its heat, and it condenses into a liquid.
3.The refrigerant runs through an expansion valve, and in the process it evaporates to become cold, low-pressure Freon gas.
4.This cold gas runs through a set of coils that allow the gas to absorb heat and cool down the air inside the building.
