How Does An Air Conditioner Work

You know that you enjoy your air conditioner, but you might not be so knowledgeable about how your air conditioner works or what air conditioner equipment is used. Air conditioners actually work a lot like refrigerators, except air conditioners work on a much larger scale than refrigerators.
The chemicals in side of an air conditioner are capable of shifting back and forth from a gas to a liquid as necessary. Those chemicals are essential for funneling the heat from inside your home to outside of your home. There are three essential parts to an air conditioner: the condenser, the compressor and the evaporator. Both the condenser and the compressor are found on the exterior of the unit while the evaporator is found on the inside of your home and is sometimes part of your furnace.
The fluid travels to the compressor as a low-pressure cool gas where it's squeezed into a fluid by the compressor. By compressing the cool gas into a fluid, the molecules of the fluid are bunched much closer together. The more bunched up the molecules are in the fluid, the higher temperature and energy it has.
The working fluid works its way out of the compressor in the form of a high pressure hot gas as it travels into the condenser. The condenser is the outside part of the air conditioner equipment that has metal fins surrounding it. The fins work much in the same way that a radiator does in that it helps to either get rid of or dissipate the heat more quickly than it would on its own.
Once the working fluid is flushed out of the condenser, its temperature cools and it is converted from a gas to a liquid under intense pressure. The liquid then works its way through the evaporator by way of a narrow and tiny hole. Once it's on the opposite side, the pressure of the liquid drops and it starts to change into a gas.
Once the liquid has shifted from gas and evaporates through air conditioning equipment, it pulls heat from the surrounding air in order to pull apart the molecules of the fluid from a liquid into a gas. The evaporator uses the metal fins to assist with switching out the thermal energy with the surrounding air. Once the working fluid has made its way out of the evaporator, it's had a chance to cool into a low pressure gas before it travels back to the compressor to start the process all over again.
One vital piece of air conditioning equipment is the fan that is connected to the evaporator that moves the air around inside of your house to blow across the fins of the evaporator. Since hot air is much lighter than cold air, the hot air in the house is buoyed upward to the top of the room. There is a vent where the air is pulled into the unit and flows down air ducts. The heated air is then used to cool all of the gas that's in the evaporator. While the heat is being pulled from the air, it's also being cooled before being blown into your house through the floor level air ducts. This process keeps going until your home is as cool as you'd like for it to be.
Now that you have a better idea of how your air conditioning equipment works, you might have a better idea of what's wrong with it the next time it's on the fritz.
