How Does an Air Conditioner Work?

The temperatures are climbing to record figures across the country and most homes are utilizing some type of air conditioner to beat the summer heat. Although we are all thankful that your air conditioner runs, the professionals at Hale's Air Conditioning Services Inc in Saint Petersburg thought they would give you a sneak peek at how an air conditioner operates.

The Basics

There’s a plethora of science behind keeping your home cool. Your air conditioner runs in a parallel way to your refrigerator, of course your air conditioner has a larger job to tackle. Both your fridge and AC cool with a consistent loop of refrigerant, in your air conditioner this refrigerant loops from inside to the outdoors. This refrigerant quickly alters from a liquid to gas and back to a liquid again. It enters your residence as a sub-cooled liquid and as it evaporates it soaks in heat from inside the home and reverts back into vapor. This vapor then moves back to the unit located outdoors where the heat is released and is then condensed back into a sub-cooled liquid.

Four Components

There are 4 core components to your AC system: a compressor, an evaporator coil, the condensing coil and an expansion valve.

The evaporator coil is the place your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be found indoors, in your garage or sometimes in your attic. Warm air transports across the cold evaporator coil and the heat is taken from the air. This cooled air is then transferred throughout your indoor space.

Your compressor is located in your outdoor condensing unit. The super-heated vapor from your evaporator coil enters into the compressor which increases the pressure of the vapor until it is converted into hot, high pressure vapor. The hot vapor then moves back into the condenser coil where less hot outdoor air runs across the coil, heat is released outdoors and the refrigerant is converted back into a sub-cooled liquid. The sub-cooled liquid returns to the indoor evaporator coil through an expansion valve or metering device. The process is then repeated.

That accomplishes your physics lesson for now…your air conditioner functions on an never-ending loop of science. We know that it’s not as crucial to you how it works, but that you are staying cool.
