How Does an Air Conditioner Work?

The temps are climbing to record highs around the country and many homes are using some type of air conditioner to combat the seasonal heat. Although we are all grateful that your air conditioner is functioning, the professionals at Cool Air Solutions in Murrieta 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 living space cool. Your air conditioner runs in a parallel way to your refrigerator, of course your AC has a larger job to tackle. Both your fridge and AC cool with a reoccurring loop of refrigerant, with your AC this refrigerant loops from inside to outside your home. This refrigerant easily converts from a liquid to gas and back to a liquid again. It enters your house 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 released and is then condensed back into a sub-cooled liquid.

Four Components

There are 4 core components to your cooling 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 possibly in your attic. Warm air moves across the cold evaporator coil and the heat is separated from the air. This cooled air is then sent throughout your indoor space.

Your compressor sits in your outdoor condensing unit. The super-heated vapor from your evaporator coil enters into the compressor which increases the pressure of the vapor until it is changed 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 adapted 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. This process is continually repeated.

That completes your physics lesson today…your air conditioner runs on an endless loop of science. We realize that it’s not as crucial to you how it works, but just the fact it’s running.
