How does a cooling coil work?

The cooling coil (or evaporating coil) starts to drop in temperature as soon as its compressor starts. The blower pulls in room air that’s hot and full of dust particles and moves it through the air filter, separating out the unwanted particles. Next, the air passes over your cooling coil. Two things happen here:

Why does the temperature of a cooling coil drop?

First, given that the coil’s temperature is much lower than the room air, the coil absorbs the heat; this causes the room’s ambient to drop; “chilling” the air. Second, the cooling coil’s temperature is lower than the room’s dew point, causing (you guessed it) dew to form on the cooling coil’s surface.

How does the hot air cycle get its name?

All this hot air is how the cycle gets its name. Once it’s cooled, the refrigerant first enters into the expansion valve, and then the evaporator, or cooling coil.

Step 1

First measure the window in order to know what size Plexiglas insert you’ll need. You can have a piece of Plexiglas cut at your local hardware store. You’ll also need a hole cut in the Plexiglas for your vent hose. It’s best to bring the vent hose with you so they can cut the hole to fit your hose correctly.

Step 2

Once you’ve got your Plexiglas, you can begin the installation process. Open the crank window and firmly attach a latch to the window as well as the frame.

Step 3

Next, using retainer clips or twist clamps securely position the insert into the window frame. You”ll then need to caulk where the casing and window frame meet in order to seal the insert and keep it waterproof. A second option would be to run weatherproof stripping where the casing and window frame meet instead of caulk.

Step 4

Now that your insert is installed weatherproofed, all that’s left is to attach the hose to your insert and enjoy the cool air.
