Heating, ventilation, air conditioning and refrigeration are all part of electromechanical technologies. This term applies to appliances and/or machinery that are both mechanical and electrical, like your air conditioning system in Cincinnati. However, understanding that your air conditioner is electromechanical in nature only gives you a small piece of the puzzle as to how it works. To truly understand how your AC keeps you comfortable, you need to understand the principles behind its operation.
How Your Air Conditioner Cools
Your air conditioner is a closed system. It uses a chemical called refrigerant to transfer heat from the inside of your home to the outside. Refrigerant can do this because it easily changes from a liquid to a gas and vice-versa. So how does this help cool you?
There are many parts in your air conditioning system, but the 3 main ones are the compressor, condenser and evaporator. The condenser and compressor are housed in the outside unit while the evaporator is placed inside.
As the cycle of your air conditioner begins, the refrigerant moves into the compressor as a cool, low pressure gas. Inside the compressor, the refrigerant is pressurized and changes from a cool, low pressure gas to a hot, high pressure gas. Once the refrigerant is pressurized, it flows into the condenser of your air conditioner; as it does this, it cools and releases heat through the condenser fins. When the refrigerant leaves the condenser, it is cooler (but still warm) and has changed from a gas to a liquid. This warm liquid then flows into the evaporator unit through a tiny hole known as a valve. When the liquid refrigerant exits the valve, its pressure has been reduced, and it begins to evaporate into a gas because the cool liquid starts to absorb the heat in the surrounding air; this heat energy turns the refrigerant back into a gas. When the refrigerant leaves the evaporator and heads back to the compressor, it is once again a cool gas, and the cycle starts again.
Where does the cool air come from? The return ducts in your air conditioning system suck in the warm air from your indoors and blow it over the evaporator coils where the refrigerant gas is. The refrigerant extracts the heat from this air and the air becomes cooled. The blower on the indoor unit blows this cool air into your home until the desired temperature is released.
Air conditioners are amazing feats of engineering, which is why it’s always best to have a trained professional attend to any issues you may have with your air conditioning system in Cincinnati.
