Most people understand that their air conditioning systems use a fan to blow cold air throughout their home but few people understand how they’re able to remove heat from your home. Having a basic understanding of the air conditioning process is a great way to be able to identify problems and know when you need to call for repair. John’s Refrigeration offers a full range of Mesa, AZ air conditioning services and we wanted to share a little about how an air conditioner works.
Mesa, AZ Air Conditioning Tip: How AC Works
Take a look below to learn a little bit about how your air conditioning system removes heat from your home.
Think of a can of compressed air that you use to clean your computer. When you squeeze the trigger air blasts out and the outside of the can gets cold. This happens because that remaining air inside the can has to expand and fill the space left by the exiting air. The expansion of that air requires energy so it pulls in all the heat energy it can from the area around it thus making the outside of the can feel cold.
The Split System
If you have a central air conditioning system then you likely have an indoor unit and an outdoor unit which is why the system is often referred to as “split”. The outdoor unit contains a fan, a set of condensing coils and a compressor. The inside unit contains another fan and the evaporator coils.
The Refrigeration Process
So here’s how all the pieces fit together. The compressor in the outdoor unit compresses the refrigerant and then circulates it inside to the evaporator coils where the pressure is released causing the coils to get very cold. A fan in the indoor unit pulls in warm air from your home and passes it over the evaporator coils where the refrigerant absorbs heat and cools the air. The now-hot refrigerant then continues outside where it enters the other set of coils in the outdoor unit and its heat is exhausted by the other fan. The process is then repeated.
