How Does an Air Conditioner Work?

The temperatures are climbing to record figures around the states and many homes are utilizing some kind of air conditioner to battle the seasonal heat. Although we are all grateful that your air conditioner runs, the team at Allstar Heating & Air Conditioning in Buellton thought they would give you a glance at how an air conditioner operates.

The Basics

There’s a plethora of science regarding keeping your house cooler. Your air conditioner runs in a parallel way to your refrigerator, however your cooling system has a larger job to manage. Both your fridge and AC cool with a consistent loop of refrigerant, however with the air conditioner this refrigerant loops from inside to outside your home. This refrigerant effortlessly alters from a liquid to gas and back to a liquid again. It flows into your residence as a sub-cooled liquid and as it evaporates it soaks in heat from inside the home and expands back into vapor. This vapor then transfers back to your outdoor unit 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 inside your home, in your garage or possibly in your attic. Warm air passes throughout the cold evaporator coil and the heat is taken from the air. This cooled air is then transferred throughout your home.

Your compressor is located in your outdoor condensing unit. The super-heated vapor from your evaporator coil flows into the compressor which surges 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 flows across the coil, heat is released outdoors and the refrigerant is changed 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. This continues repeatedly throughout the process.

That completes your physics lesson today…your air conditioner functions on an never-ending loop of science. We understand that it’s not as important to you how it works, but that you are staying cool. If you’d like to talk about staying cool and comfortable in Buellton give us a call at 805-242-9638. Thanks to science and our pros, you’ll get through this hot summer.
