How Does Your Central Air Conditioner Cool Your Home?
April 17, 2019
Aside from the professionals, like ours at Comfort Zone Heating & Cooling, who really thinks about air conditioners and their components? Air conditioners keep your Weiser, ID, home or business cool and comfy when the outside temperatures are high, and that’s all you really need to know, right? Well, air conditioners do so much more than just cool, like dehumidify your home or business and help keep your inside air cleaner. Understanding a bit of its basic components and how they work can help you identify a problem or malfunction when it occurs.
Air Conditioner OverviewAs already mentioned, your air conditioner does more than just cool. It dehumidifies by reducing the volume of humid air, thereby taking a portion of its moisture. That’s the reason for pans and drains with air conditioners. Your air conditioner also aids in cleaning the air by removing allergen and debris particles from the airflow where they attach to the filter. But the largest purpose of your air conditioner is to remove the heat from your inside air and cool it, providing the maximum indoor comfort. Looking at this side of your air conditioner, most conventional central air conditioners have a hot side, which is located outside, and a cool side, located inside. Since these air conditioners have both outdoor and indoor components, many times you’ll see your air conditioner referred to as a split-system air conditioner. In the very basest of explanations, here’s how your air conditioner works:
- Air conditioners transfer heat to the outside, extracting it from the inside air.
- The compressed gas refrigerant in the system (you probably know DuPont’s Freon® refrigerant) absorbs the excess heat before it’s pumped through the piping in a closed system to an outside coil.
- A fan blows air over the hot coil, transferring the absorbed heat in the refrigerant to the outdoor air.
- Since the inside heat has been removed, the indoor air is now cool. As a result, the refrigerant is re-cooled and condensed here, then sent back to circulate through the system to begin the process again.
Air Conditioner ComponentsAn air conditioner is made up of many components, but the major parts doing the heavy lifting of moving the air indoors and outdoors are the evaporator, condenser, expansion valve, and compressor. Keep in mind they’re each either located outside (the hot side) or inside (the cool side).
