Without a central air conditioner, distributing cool air evenly in your home is likely a problem you will face. Some rooms will be cooler, while others might become hotter. Leaving doors open and hoping cool air will slip to the other rooms is not going to always work.
There are several steps you can take to move cool air from one room to another, and in this post, I’ll be sharing them with you. Enjoy.
Here are five ways to get cool air from one room to another:
- Use an Air Circulator
- Place a Fan in the Doorway
- Use a Box Fan in the Window
- Install a Whole House Fan
- Add Ductwork & an Exhaust Fan Linking the Two Rooms
There are different types of fans you can use in your home. Air circulators are not your normal type of fan. These are fans that are built to work by keeping the air in a room always in continual motion. Air circulators use a combination of different elements including deep-pitched propellers, blade ducts, and air accelerators, which push air around a room with power.
To get cool air from one room to another, all you need is to place the air circulator in the doorway of the cooler room. Because cool air is denser and sinks below, the air circulator should effectively suck it and blow it to the other room. Alternatively, you can blow out hot air to the cooler room. This will create pressure in the cooler room which will force air to move into other rooms.
Air circulators come in a variety of different forms, such as pedestal, tower, and floor fans. Floor air circulating fans are best for moving cool air to other rooms, while taller pedestal air circulating fans are good for pumping out hot air out of a room.
Using a floor fan is another way of distributing air to an adjoining room. For example, if you have an air conditioner installed in a particular room, but you would also like to cool another room, first, close off any entrances in the air-conditioned room.
Second, place a floor fan in the doorway facing the room that needs to be cooled. As the fan pushes cool air to the other room, hot air will escape leaving the room temperature cooler.
This method utilizes a law in physics known as convection. The difference in temperature will find each other. Although leaving the door open to both rooms also works, a fan in the doorway speeds the movement of air between the two rooms.
The difference between using either a floor or a box fan is the placement. For a box fan, instead of placing them in the doorway, put it in the window of the warmer room. The box fan should also be positioned to blow out air. This forces warm air to be exhausted out of a room. The negative pressure created also sucks in cool air from the adjoining rooms.
For better efficiency, close all the openings in your home except the one that links the two rooms and leaves a window open in the cooler room to help circulate cool air.
Whole house fans work by pulling air, usually hot air hovering above a room, and exhausting it through the room or attic. According to the US Department of Energy, a whole-house fan can substitute air conditioning in most climates for most of the year.
Using a whole house fan to move cool air from one room to another is a very easy and effective way. All you need is to install a whole-house fan in the ceiling of the hotter room. As the whole house fan exhausts hot air from the room, it will create negative pressure in the room, which will suck in cool air from other rooms in your home.
Apart from cooling an individual room, whole-house fans can be installed to cool your entire home. This is possible when the outdoor temperature is colder than the temperature in your own home. All you need to do is open the windows or other openings in your home, turn on the whole house fan and let it do its job.
In some cases, you might want to move cold air into a room that is not adjacent to the cooler room.
Installing ductwork to act as an airway between the two rooms is a method you can try. An exhaust fan on the warmer room is used to pull cool air from the cold room.
If you choose to use this method, keep the ductwork straight with fewer curves and as short as possible. A powerful exhaust fan that can move larger quantities of air through the ductwork should be used.
An advantage of this method is that it can also be used to move warm air between the two rooms even in the winter.
The above methods should help you move cool air between two rooms. Improving the ventilation in your home can also help distribute cool air and save on cooling or even heating bills. Setting up proper air circulation is one of the main things that can keep your home cool during the summer.
