Portable Air Conditioners They also both require ventilation in order to work properly. The big advantage with a portable air conditioner over a window AC unit is the fact you can use it in rooms with or without windows. It is also easier to move from room to room if you have a window and a vent kit.
What happens if you don't vent portable air conditioner?
If you take off the vent hose, though, the AC will just run your room air through a cycle between cool-and-dry and hot-and-humid. Since most units consume about 1,000 watts of electricity, this would actually heat up your room far more than it would cool off.
How do you bring outside air?

Why vent a portable AC?
The principle is to expel hot air through vent hose. In very simple terms, they take heat from your room and expel it. That is why venting is necessary when using them. But venting in portable AC is flexible compared to window AC units that have fixed position and no flexibility in venting.
How to keep AC from mixing?
Just keep the vent hose on. Keep it in the opposite direction to the front of your unit. Have as much as separation between the two air streams as possible. This would prevent active mixing of the airflow at two temperatures and increase cooling effectiveness of your portable AC.
How to improve outdoor cooling?
You can improve the cooling by keeping the vent hose opposite to the direction of cooling and far away from the cooling outlet. The best options for outdoor cooling are misting fan and evaporative cooler .
What is the difference between an evaporative cooler and a misting fan?
Evaporative cooler uses same principle as the misting fan. The difference is that the evaporation of water to make air cool is somewhat passive. It has cooling pads with large surface area that absorb water. The fan pulls air through them so evaporation carried out is larger.

If these two temperature airflows are released close to each other then this would nullify their effects . Heat will be transferred from the cool air to hot air resulting in a stream of air that reaches you at the same temperature as the external environment. Only a miniscule amount of cooling will reach you.

How does a portable AC work?
How Do Portable Air Conditioners Work. Portable air conditioners work by pulling hot air from the room into the unit. The motor inside the portable AC then cools the air for circulation throughout the room. The portable air conditioner also takes the warm air and excess moisture and pushes it through a hose and out the window.
What is inside of air conditioning unit?
If you take a moment to inspect your air conditioning unit, you will see that there is an inside component and an outside component, connected by copper lines. These copper lines are filled with refrigerant, either in a liquid or gaseous state. That is the only thing that is passing between the two units.
How does an AC unit work?
How Your AC Unit Works. The indoor portion of your unit has an air conditioner return air intake, usually located on the ceiling. This return air intake grille typically includes some type of filter to keep dust and debris out, while allowing air to pass through.
How does a filtered air conditioner work?
The air passes through the filter of the unit, and quickly passes over the supercooled coils inside. This process transfers the heat out of the air and into the coils , before the now-cold filtered air is pushed back out into your home.
How does an outdoor unit work?
Likewise, your outdoor unit uses a fan to draw air in, taking the heat back out of the refrigerant and allowing it to cool down once more before being recycled. That air simply passes through the outdoor unit, whisking away heat and continuing along.
