How Does an Air Conditioner Work?

The weather is reaching record figures throughout the U.S. and the majority of homes are utilizing some type of air conditioner to beat the seasonal heat. Though we are all grateful that your air conditioner runs, the experts at Bell Air Conditioning Inc. in Belton thought they would give you a look at how an air conditioner operates.

The Basics

There’s plenty of science behind keeping your house cooler. Your air conditioner runs in a comparable way to your refrigerator, but your cooling system has a larger task to handle. Both your fridge and AC cool with a consistent loop of refrigerant, however with the air conditioner this refrigerant loops from inside to to the external part of your home. This refrigerant quickly changes 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 reverts back into vapor. This vapor then travels back to the unit outside where the heat is freed and is then condensed back into a sub-cooled liquid.

Four Components

There are 4 main components to your AC 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 established inside your home, in your garage or possibly in your attic. Warm air moves through the cold evaporator coil and the heat is removed from the air. This cooled air is then transferred throughout the space inside your home.

Your compressor is located 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 moves across the coil, heat is pushed outdoors and the refrigerant is adapted back into a sub-cooled liquid. The sub-cooled liquid returns to the indoor evaporator coil through an expansion valve or metering device. This continues repeatedly throughout the process.

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