How Does an Air Conditioner Work?
Have you ever thought about how your air conditioner can make your home cool, bringing you comfort, even when it’s so hot outside? Getting to know and understand the working process of your air conditioner can actually be helpful when choosing a HVAC contractor to provide you with air conditioning maintenance. This choice is important and should not be taken lightly. If you want a reputable service provider to make sure your AC unit is in top shape you should contact Marc Cooling based in Miami, FL.
How an Air Conditioner Works
Your air conditioner works the same way as your refrigerator does. The only major difference is that it cools your whole home instead of just your food. It does so by using a refrigerant that easily changes from a liquid to a gas and vice versa.
Air conditioners are made up of two main parts: the evaporator, which is located inside and the condenser, located outside, housing the compressor (assuming you have a split AC system). The cooling process starts when the air conditioner refrigerant enters the compressor as a low pressure, cool gas. The compressor places pressure on the gas. As a result the molecules are packed together raising the temperature and energy of the gas.
At this point the refrigerant gas is quite hot as it moves into the condenser. The condenser is the part of the air conditioner with the fins. The fins help scatter heat away from the gas, ultimately causing it to condense into a cool liquid, still under significantly high pressure. The liquid then transfers into the evaporator through a tiny hole. Once it sweeps through the hole, the pressure is released, and it quickly vaporizes into a gas.
As the refrigerant evaporates, it absorbs heat from the air surrounding it. When it leaves the evaporator it is a low pressure, cool gas – exactly as it was when it started! Then the process begins all over again.
How Your Air Conditioner Cools Your Home
So how does that entire process actually cool the air in your home? A fan is connected to the evaporator. It circulates the air inside your property and blows it across the cold evaporator fins. Because hot air is lighter than cold air, the hot air rises to the ceiling and is being pulled through the vents, into the ducts, eventually reaching and passing over the evaporator to be cooled once again.
Keep Your Filters Clean!
Because air is traveling through the filters before it moves through the rest of your home, it is essential that you change or clean your filters every month. As the air moves from the inside of your home through your ducts, it’s will collect dust and other contaminants. This is very good, because it’s pulling them away from the air you’re breathing! Unfortunately, as the filters collect those allergens, dust particles and bacteria, the movement of the air through them gets harder and harder. Keep in mind that poor airflow is one of the main issues that can cause your evaporator to freeze! This situation can lead to unpleasant problems, such as refrigerant leaks that may require major air conditioning repairs.
Now you know exactly how your air conditioner works, you can take better care of it so it doesn’t break down when you need it the most. If you need any type of air conditioning maintenance, call Marc Cooling today!
