How Does an Air Conditioner Work?

The weather is hitting record numbers throughout the U.S. and most homes are utilizing some type of air conditioner to combat the smoldering heat. While we are all thankful that your air conditioner runs, the experts at Alltemp Comfort Services LLC in Winnsboro thought they would give you a glance at how an air conditioner operates.

The Basics

There’s a plethora of science involved in keeping your house cool. Your air conditioner operates in a parallel way to your refrigerator, however your cooling system has a bigger task to handle. Both your fridge and AC cool with a reoccurring loop of refrigerant, however with the air conditioner this refrigerant loops from inside to the outdoors. This refrigerant effortlessly alters from a liquid to gas and back to a liquid again. It goes into your home as a sub-cooled liquid and as it evaporates it absorbs heat from inside the home and expands back into vapor. This vapor then moves back to the unit located outdoors where the heat is freed and is then condensed back into a sub-cooled liquid.

Four Components

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

The evaporator coil is the location your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be located in the home, in your garage or even in your attic. Warm air transports through the cold evaporator coil and the heat is taken from the air. This cooled air is then sent throughout the space inside your home.

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

That accomplishes your physics lesson of the day…your air conditioner functions on an relentless loop of science. We realize that it’s not as top-priority to you how it works, but that you are staying cool. If you’d like to talk about staying cool and comfortable in Winnsboro contact us at 803-220-0753.
