How Does an Air Conditioner Work?

The temps are climbing to record numbers around the states and many homes are utilizing some variety of air conditioner to battle the seasonal heat. Although we are all thankful that your air conditioner runs, the professionals at Comfort Zone Inc in Cape Coral thought they would give you a glance at how an air conditioner operates.

The Basics

There’s plenty of science regarding keeping your living space at a comfortable temperature. Your air conditioner runs in a comparable way to your refrigerator, but your cooling system has a more difficult responsibility to handle. Both your fridge and AC cool with a constant loop of refrigerant, with your AC this refrigerant loops from inside to to the external part of your home. This refrigerant easily alters from a liquid to gas and back to a liquid again. It enters your home as a sub-cooled liquid and as it evaporates it takes in heat from inside the home and turns back into vapor. This vapor then moves 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 elements to your cooling system: a compressor, an evaporator coil, the condensing coil and an expansion valve.

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

Your compressor resides in your outdoor condensing unit. The super-heated vapor from your evaporator coil goes into the compressor which surges the pressure of the vapor until it is converted 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 converted back into a sub-cooled liquid. This sub-cooled liquid is then returned to the indoor evaporator coil through an expansion valve or metering device. The process is then repeated.

That concludes your physics lesson today…your air conditioner runs on an endless loop of science. We understand that it’s not as top-priority to you how it works, but that you are staying cool.
