How a window air conditioner work – Do you use a window air conditioner in your home or office, and you may have also asked how a window air conditioner works. so you can make cooling water in the room of the house or office building where you work.
ok, In this post servicesparepart will exlpain clearly how a window air conditioner work. maybe things you don’t know about the work process or system of a window air conditioner that sometimes quickly looks complicated.
to be understood more easily, we will cover part by part in the window air conditioner system which includes :
- The Room Air Cycle Process
- The Hot Air Cycle Process
- What The Thermostat Does Process
- Controlling Air Speed Process
- Function of the Air Filters Process
The Room Air Cycle Process
The core of the AC window is to get moving air.
The air inside your room, on the front of the AC where the cooling coil is located, is what we call “room air”.
As soon as the AC window kicks in, the blower lights up, followed by the compressor. The cooling coil (or evaporator coil) starts to drop in temperature as soon as the compressor starts.
The blower draws air – hot, and full of dust particles – and moves it through the air filter, separating unwanted particles.
Next, air passes through your cooling coil; two things happen here.
First, given that the coil temperature is much lower than room air, the coil absorbs heat; this causes ambient room to decrease; “Cool” air.
Second, the temperature of the cooling coil is lower than the dew point of the room, causing dew (you guessed it) to form on the surface of the cooling coil. This removes moisture from the air, decreasing the value of its relative humidity.
This low-temperature and low-humidity air is sucked in by the AC blower, and “exhaled” at high speed, passing through a metal channel, and blown through the AC front panel. This pushes air into the room and shivers it, keeping temperature and humidity levels low.
Of course, it doesn’t stay like that; room air has a higher level of humidity and temperature than cold air, transferring the property to new air. Which means it will be sucked again by the blower and the whole cycle repeats.
The Hot Air Cycle Process
Another important aspect of understanding how AC windows work is the cycle of hot air.
This cycle focuses mainly on external air, or “atmosphere” used to cool the condenser.
So what is the condenser?
The condenser is part of the air conditioner that is outdoors. It is exposed to your external atmosphere, and the condenser propeller fan sucks in a high-temperature atmosphere and blows air over the condenser.
The condenser itself contains refrigerants, but at high temperatures; it needs to be cooled before giving cooling. “Atmospheric” air is relatively hot; after absorbing the condenser heat, the temperature rises higher.
Stand behind the AC window some time and see for yourself; heat back there! All this hot air is how the cycle gets its name.
After cooling, the first refrigerant enters the expansion valve, and then the evaporator – or cooling coil. Hot air blends with the atmosphere and atmospheric air is freshly absorbed and pushed upwards on the condenser – thus continuing the cycle of hot air.
What The Thermostat Does Process
This is another key factor in understanding how a window air conditioner works. Each air conditioner has a thermostat.
Cheap products cut costs by using a rotary dial, while the best window AC models include digital controls.
No matter how you set it, you enter the desired temperature equilibrium for the room; after the thermostat detects that you have reached the temperature you want, it stops the compressor, and the cycle stops.
However, after the room temperature rises once more, the thermostat removes its grip, kicks the compressor back into gear, and makes the cycle run.
With that, setting your thermostat lower won’t cool things faster, it’s just a setting that tells the unit when it’s time to turn off.
Controlling Air Speed Process
Blower fans on the other hand, have speeds that you can set.
Nothing too fancy here; it’s a fan; setting it faster means the air will rotate through the room faster, which can speed up the cooling process.
It’s also nice to stand in front if you bake in a hot room.
Function of the Air Filters Process
At the beginning of this article, we mention how the blower pulls the room air and along with that comes dust particles.
Fortunately, the AC window unit came with an air filter capturing all of that.
It’s important to clean this every few weeks or more. Skip this section, and the filter becomes blocked. The clogged filter means dirt starts to enter your evaporator coil, strangling it. After this happens, the AC device will stop functioning and you must pay the evaporator coil to be cleaned by a professional or replace the entire unit with a new one.
Cleaning the air filter only takes a few minutes of work and is very valuable every second. Maintain regularly, and your window air conditioner will provide happy cooling for years to come.
Now you know everything about how window air conditioners work.
