As the scorching heat nears, one reliable companion emerges to provide the ultimate relief – the air conditioner. Have you ever wondered how this magical device manages to transform hot air into a refreshing breeze? Or maybe you have a problem with your AC and are looking to learn more? In this blog post, we’ll unravel the mechanics behind your AC and explore its inner workings.

The Basics of How An Air Conditioner Works

At its core, an air conditioner operates on a simple principle: it removes heat from the air and expels it outside, leaving the indoor environment pleasantly cool. This process involves 4 key components working together – the compressor, condenser, expansion valve, and evaporator – along with a refrigerant that passes through all these components.

1. Compressor – Building Up the Pressure

The compressor, located in the outdoor unit of a split AC system, is responsible for compressing the refrigerant, a special fluid that circulates throughout the system, absorbing and releasing heat. By doing so, it raises the refrigerant’s temperature and pressure, transforming it into a hot, high-pressure gas and preparing it for the next step.

2. Condenser – Releasing the Heat

After leaving the compressor, the refrigerant flows into the condenser, another unit in the outdoor section. Here, the refrigerant releases the heat it absorbed from the indoor air. The condenser’s fan blows outside air over the condenser coils, which helps the refrigerant release the heat and transforms it into a high-pressure liquid.

3. Expansion Valve – Regulating the Flow and More Cooling

The high-pressure liquid refrigerant then passes through the expansion valve, a small component of the indoor section that acts as a gatekeeper. The valve restricts the flow of refrigerant and causes a sudden drop in pressure. This leads to a significant decrease in the refrigerant’s temperature, meaning the refrigerant is cool enough to move to the evaporator.

4. Evaporator – Cooling the Air

The now-cool refrigerant enters the evaporator – part of the indoor unit of a split AC system or in the main body of a window AC. As warm air from the indoor environment comes in contact with the evaporator coils, the cold refrigerant absorbs the heat from the air, thereby cooling it. The cooled air is then blown back into the indoor room through the AC vents.

Lastly, the cycle repeats! The refrigerant, now holding the heat it absorbed from the indoor air, turns into a low-pressure gas and returns to the compressor to restart the process. This continuous cycle allows the air conditioner to expel hot air and maintain a cool and comfortable indoor temperature. 

Understanding how an air conditioner works helps you appreciate the technology behind cooling your home or business and encourages you to take better care of your AC system. Routine maintenance and proper usage contribute to better performance and longevity of your air conditioner, so reach out to professionals to stay cool!
