Window Air Conditioner How It Works: 5 Best Processes!

Today, we are going to ponder on the topic, “Window air conditioner how it works.” Like any other air conditioner, it absorbs humidity from your room and cools it with the help of a refrigerant.

Freon is the most common refrigerant used for air conditioners.

It’s also one of the widely-used types of AC throughout the years. This type of AC is a square-shaped unit inserted through your wall or window. And all of its components are included in one casing.

Some claim it’s the most manageable type, yet there’s a lot more to it than we ever realized. How does it work?


The Operation Of A Window Air Conditioner

Though it’s only composed of one casing, it has many complicated components that provide one’s room with excellent air quality. And the whole process executed by this equipment is mesmerizing.

We look at our AC, thinking that it cools our room and nothing more. But they do a lot of things, and we should be curious about that. So we should let out curiosity ask about its whole operation.

Without further ado, here is what you need to know regarding “Window air conditioner how it works.”


Process #1. Circulation of room air

This cycle takes place in the interior side of your AC, and it involves removing moisture from your room and cooling it. But where and how does it start?

So, when you switch on your AC, its components, including the blower and compressor, will have electricity to work. Next, your blower will start to absorb the warm air from your room, and it will pass through your air filter, causing the air to purify.

The filtered air will pass through the evaporator coils. Because the air is warmer than the surface, the circuit will absorb the heat, resulting in tiny water droplets.

And the absorbed air is now a new cold product. In which the blower will exhale it through the ducts and out of the front cover. This process is a cycle, so it will continue until your AC is powered off.


Process #2. Purpose of air filter

We have already mentioned the air filter earlier, and its function in the overall unit is necessary. The AC absorbs air from your room, and the filter removes all the dirt and debris.

Without it, the particles might clog other parts of your AC and keep it from functioning efficiently. So, you should clean it once in two weeks.

You also don’t want the air released from your AC to carry the dust from the filter. And it will provide your home with fresher air and reliable air circulation.


Process #3. The cycle of warm air in the exterior side

Based on its name, this process takes place on the outer side of your AC. And it focuses on cooling the condenser, which is essential for the component to cool the refrigerant.

It also involves dealing with high-temperature air in the environment. And this is the reason why the back of your AC feels warm when touched.

Your AC has a propeller fan near the condenser, and it allows the air outside to enter the AC from the back. But, unfortunately, it usually absorbs the air.

The absorbed air removes the heat from the condenser, which makes the atmosphere even hotter.

Nevertheless, the condenser is now cooled and ready to perform its function: to cool the refrigerant. The refrigerant then travels to the valves and coils. And the entire cycle continues.


Process #4. Thermostat adjustment

All ACs have a thermostat. It could be in the unit itself or the remote. Despite the differences, you can still adjust the temperature of the air released from your AC.

Whenever you feel warm, you lower the temperature. But as time pass by, you feel a little colder, so you keep adjusting it until you feel contented.

So, when you alter the temperature, there’s a change in the room air cycle and the external air cycle. It could be that the condenser cools more amounts of refrigerant. Or more room air is converted into cool air.

However, note that adjusting the thermostat does not make the cycle faster, but other factors are adjusted. And in your window AC, the settings usually display numbers that indicate how cold you want it to be. But some use these numbers to indicate the timer.


Process #5. Fan intensity

Aside from the temperature, your thermostat also has settings for fan speed. And this process is responsible for cooling your room faster.

You can turn the controls to align your preferred fan speed. The higher the rate, the faster the cycle will occur. And it would result in more air blown out by your AC unit.

The most excellent feature is that you can stand next to the front panel and feel all of the cold air rush into your face. This scenario is the most common during the summer season.


It’s A Wrap

And that concludes the article about “Window air conditioner how it works.”

You acquainted yourself with the operation of your window air conditioner. And you’ll be able to answer your question regarding where the chilly air originated.

There are still things you need to discover inside your unit, especially about the valves and cables. But we’ll reserve that for the future. Thank you for reading!
