How Does an Air Conditioner Work?

The temperatures are reaching record numbers throughout the states and most homes are utilizing some type of air conditioner to battle the seasonal heat. Although we are all appreciative that your air conditioner works, the experts at Controlled Comfort HVAC Inc in Carpentersville would like to inform you how it works.

The Basics

There’s a lot of science behind keeping your house cool. Your air conditioner operates in a comparable way to your refrigerator, but your cooling system has a larger responsibility 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 goes into your residence as a sub-cooled liquid and as it evaporates it takes in heat from the indoors 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 central sections to your cooling 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 established in the home, in your garage or possibly in your attic. Warm air moves through the cold evaporator coil and the heat is taken from the air. This cooled air is then released throughout the space inside your home.

Your compressor is located in your outdoor condensing unit. The super-heated vapor from your evaporator coil flows into the compressor which increases the pressure of the vapor until it is converted into hot, high pressure vapor. The hot vapor then enters back into the condenser coil where less hot outdoor air runs across the coil, heat is moved 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 concludes your physics lesson of the day…your air conditioner runs on an never-ending loop of science. We understand that it’s not as crucial to you how it works, but that you are staying cool.
