How do Portable Air Conditioners work?

Portable air conditioner units work similarly to conventional air conditioning units. Portable air conditioners work by pulling hot air from the room into the unit. The motor inside the portable air conditioner then cools the air in order to circulate it throughout the room. The portable air conditioner also absorbs the warm air and excess moisture and pushes it through a hose and out the window. This is why you must learn how to ventilate a portable window air conditioner without Windows. In this article, you might find a way to vent your portable air conditioner.

​How to vent a portable air conditioner without Windows?

When a portable air conditioner is turned on, it draws warm air from the room. It will then cool the air and send it back to your room. Meanwhile, air conditioners will have to expel hot air. If not ventilated, air conditioners can drain warm air back into your room, reducing its cooling effectiveness.

Here's how to ventilate a portable air conditioner without Windows.

  • Vent through doors
  • Vent through exterior walls
  • Vent through Interior Wall
  • Vent through the ceiling
  • Vent through a chimney

1. Vent through doors

In addition to ventilating portable air conditioners through Windows, another of the simplest forms of air conditioner ventilation is through the doors. Open a slit for ventilation and let the hose out when using portable air conditioners. If you take it camping or on a trip, it's even more convenient. Simply unzip the tent and let the vent out.

However, the hoses of most portable air conditioners are usually not long enough. Therefore, you must place the portable air conditioner near the door. If placed far from the door, the hose may be unable to expel hot air outside.

2. Vent through exterior walls

Vent for portable air conditioner through exterior walls. If the room you are cooling has an exterior wall that leads directly to the outside, you can dig a hole in that wall that is large enough to provide adequate ventilation for all the hot air you are sucking out of the interior space by the hose.

It is a good idea to look at the structural plans and details of the building and use a stud finder to locate any supporting studs or beams before cutting holes in the wall. After all, you don't want to weaken the structure of the building at all, and you want to avoid cutting pipes or wires in the exterior walls.

Once you find a safe place, one that won't interfere with building systems or structures, you can carefully cut through the hole with a circular saw or similar tool. Be careful when cutting brick, stone, siding, and other exterior materials. Or the building structure might be destroyed.

3. Vent through interior walls

In addition to ventilation through the exterior walls, you can also ventilate portable air conditioning units through the interior walls. Suppose the windowless room you want to cool is near the center of the building and has no external walls. You can cut a hole in one of the inner walls and insert the device's ventilation hose into the other room. So the device will suck heat out of one room and pour it into another.

But this might be a problem: the second room gets hotter. So the other room should be an infrequently used laundry room, utility room, storage area, or garage.

4. Vent through the ceiling

If the wall method doesn't work well in your house, you can try to vent through the ceiling. In this case, you will need to install the air conditioner higher up in the room, perhaps on top of a sturdy metal shelving unit or bracket. Or you can elongate the exhaust hose so that the air conditioning unit can be placed on the floor, and the hose can be extended along the wall to the ceiling to be vented.

Use a ladder so you can get close to the ceiling. Carefully cut a hole in the ceiling, or remove all or part of the panel from the ceiling. In addition, you must monitor the humidity and temperature of the ceiling space to ensure that the heat and humidity levels are not too high. If it's too humid, mold can develop in the ceiling space.

5. Vent through a chimney

Another method is to vent your portable air conditioner through a chimney. You can vent the hot air through the chimney. However, it absolutely must be an unused chimney in an unused fireplace. Never attempt to ventilate a portable air conditioning unit through a functioning, working chimney or fireplace -- this is a considerable safety risk.

Before you drain the air conditioning unit into the chimney, especially if it has not been used for a long time, it is a good idea to check to ensure the chimney is clean and open.
