Yes, a portable air conditioner can be exhausted to another interior room through a vent in an adjoining wall. This method is often referred to as "dual-hose" or "dual-duct" setup and is a practical solution to address some of the limitations of single-hose portable air conditioners.
In a standard single-hose portable air conditioner, the unit takes in warm air from the room it's cooling, cools it down, and then exhausts the hot air through a hose that leads outside. This process creates a negative pressure in the room, which can result in warm air being drawn into the cooled space from other areas, like adjacent rooms or outdoors. As a result, single-hose portable ACs may have reduced overall efficiency.
Dual-hose portable air conditioners, on the other hand, have two separate hoses: one for intake and one for exhaust. The intake hose draws air from the outside, while the exhaust hose directs hot air back outside. This configuration eliminates the negative pressure issue and allows for more efficient cooling.
To set up a dual-hose portable air conditioner in a way that exhausts the hot air into an adjoining room, you'll need to:
- Position the portable AC near the vent in the wall that leads to the adjoining room.
- Attach the intake hose to the designated intake port on the AC unit.
- Connect the exhaust hose to the designated exhaust port on the AC unit.
- Extend the exhaust hose and route it to the vent in the adjoining wall.
- Make sure to seal any gaps around the hoses to prevent air leaks.
By exhausting the hot air into the adjoining room, you can cool that space as well, provided it has proper ventilation to allow the hot air to dissipate naturally or be exhausted outside through a window or another vent. Keep in mind that this setup might not be as efficient as exhausting the hot air directly outside, but it can still be a viable option to improve cooling in multiple rooms without the need for additional units.
Always refer to the manufacturer's guidelines and recommendations for the specific portable air conditioner model you have, as they may provide additional instructions or safety precautions for setting up the unit in this manner.
