The summer season is here with record temps across the country, and with many houses having some sort of air conditioner, it’s the ideal way to get out of the heat. As you are unwinding in your comfortably cool home or office, appreciating that your air conditioner works, let’s take a peek at how a normal cooling system functions.
Your air conditioner operates the similar to your refrigerator, but understandably rather than keeping a small space cool, it has to work to cool down your whole house. Both use a refrigerant that converts swiftly from liquid to gas, back to liquid again. In your air conditioner, the refrigerant is on a regular loop from the outdoors to the inside of your home. It goes into the home as a sub-cooled liquid that evaporates and assembles or takes in heat from your indoor air, expands back into vapor, then returns to the outside condensing unit where it dissipates the heat and is transferred back to a sub-cooled liquid.
Your AC system is made of four key components: an evaporator coil, a compressor, a condensing coil, and an expansion valve or metering device.
The part where your refrigerant evaporates from a sub-cooled liquid to a super-heated vapor is called the evaporator coil, which may be inside your home, in your attic, or located in the garage. As warm indoor air is moved over the cold evaporator coil, heat is detached from the air…and the cooler air is driven among your indoor space.
From the evaporator coil, the now super-heated vapor refrigerant flows to the compressor stationed in your outside condensing unit. The compressor increases the pressure of the vapor until it turns into a hot, high pressure vapor. The now super-hot vapor meets the condenser coil where a lower amount hot air blows by the coil, moving heat to the outdoors, and changes the refrigerant to a sub-cooled liquid. The sub-cooled liquid refrigerant is returned to the indoor evaporator coil where, through an expansion valve or metering device, the process is redone.
Your air conditioner is an endless loop of movement. We realize the important thing to you isn’t really how it works, but that it’s working the right way.
