How Does an Air Conditioner Work?

The weather is climbing to record numbers throughout the country and many homes are using some type of air conditioner to battle the summer heat. While we are all appreciative that your air conditioner is functioning, the team at Eco Fresh HVAC Inc. in Anaheim thought they would give you a glance at how an air conditioner operates.

The Basics

There’s plenty of science behind keeping your living space cool. Your air conditioner runs in a comparable way to your refrigerator, of course your AC has a more difficult responsibility to manage. Both your fridge and AC cool with a reoccurring loop of refrigerant, in your air conditioner this refrigerant loops from inside to outside your home. This refrigerant quickly alters from a liquid to gas and back to a liquid again. It flows into your home as a sub-cooled liquid and as it evaporates it soaks in heat from the indoors and turns 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 main sections to your air conditioner unit: 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 established inside your home, in your garage or sometimes in your attic. Warm air passes across the cold evaporator coil and the heat is taken from the air. This cooled air is then sent throughout your home.

Your compressor resides in your outdoor condensing unit. The super-heated vapor from your evaporator coil enters 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 runs across the coil, heat is moved 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 accomplishes your physics lesson today…your air conditioner functions on an relentless loop of science. We know that it’s not as top-priority to you how it works, but just the fact it’s running.
