Yes, a portable air conditioner can be exhausted to another interior room through a vent in an adjoining wall. Portable air conditioners are designed to be versatile and offer flexible installation options, including using a vent kit to exhaust hot air and humidity from the room they are cooling. While they typically come with a window venting kit for standard window installations, you can modify the setup to vent the hot air into an adjacent room.
To achieve this, you'll need to do the following:
Position the portable air conditioner: Place the portable AC unit near the wall where you want to install the vent. Make sure it's positioned close enough to reach the adjoining room.
Create an opening: Cut a hole in the wall of the room where you want to vent the hot air. The size of the hole should match the diameter of the exhaust hose provided with the portable air conditioner.
Install the vent: Connect the exhaust hose to the opening in the wall securely. You may need to use an adaptor or sealing materials to ensure a tight fit and prevent air leaks.
Insulate and seal: Properly insulate and seal any gaps around the exhaust hose and vent opening to prevent the escape of cooled air or the entry of warm air.
Set up the window vent in the receiving room: In the adjacent room where the hot air is being exhausted, you can either direct the hose outside through a window or create a similar hole in the wall and install another vent to discharge the hot air.
It's important to note that while venting to an adjacent room is possible, it may not be the most efficient method of exhausting hot air. Portable air conditioners work best when the hot air is vented outside directly through a window or another suitable opening. Venting to another room can cause that room to heat up and reduce the overall cooling efficiency of the portable AC unit. Additionally, if the adjoining room is not adequately ventilated or doesn't have a way to expel the hot air, it may lead to an uncomfortable and less effective cooling experience.
If possible, venting the portable air conditioner directly to the outside is still the recommended method for optimal cooling performance. However, if you must vent to another interior room, ensure proper ventilation in that room to maintain a comfortable environment.
