What is a window fan for?
If you want to maintain a moderate temperature in the room at a lower cost, then the air conditioner is not an option. They are too expensive to buy and maintain, so its affordability is a question. But there are specific devices available in the market which are not a replacement for an air-conditioner but make the environment moderate by maintaining a suitable temperature in the room.
A window fan is one such device that is available in various models and makes in the market. Window fans can also be used in the intervals when the air-conditioners are turned off to save electricity. The window fans are used to pull in the air and exhaust it out. The configuration of the Fan can be adjusted for blowing in or blowing out.
You can also adjust the fan speed according to your convenience and the temperature requirement of the room. Some window fans have a single fan in the frame, while some window fans offer two fans in the structure, which can be used for blowing in and out of the air. Modern window fans can be installed in the window frames of various sizes. They have side panels, which can be extended according to the size of the window frame. With less than 60% of the energy consumption compared to an air-conditioner, window fans are the best-rated airflow device used by the customers these days.
How to select a perfect window fan?
The choice of window fan will affect the ambiance and temperature of the room or an office. Thus the selection of a perfect window fan is a critical phase. Following are some of the factors which can be decisive in the range of an ideal window fan for you:
By reversibility, we mean the fan direction. The window fan can both be used for the intake and outflow of the air. How to intake and flow of the air will depend upon the fan direction. Some window fans are manually reversible. You have to remove the unit and to install it in the opposite direction to use it as an exhaust fan to remove the hot air and bad odor. This is a time-consuming process and will require some effort as well. However, its simple solution is the purchase of electrically reversible fans. The electrically reversible fans can be reversed just by pressing a button. The Fan starts to rotate in the opposite direction performing the outflow of air instead of inflow. So a perfect window fan should offer the feature of electrical reversibility.
By airflow, we mean the cooling capacity or power of the Fan. The airflow is measured by calculating the air’s velocity, entering, or leaving the space in which a fan is used. It is practically impossible for everyone to measure the airflow of the Fan, so it is generally measured by the manufacturers and written on the packing of the Fan. It is measured in the units of CFM. Although most of the people go for the fans with the highest CFM, but it is advised to calculate the airflow requirement of the room by considering the required factors and select the Fan with appropriate CFM to avoid any wastage of energy.
Of the fans, here are the units of window fans that offer a single bigger fan in their frame for more excellent airflow and to maintain the temperature in bigger rooms and halls. While there are models of window fans that incorporate two smaller fans in its structure, the airflow is relatively less, but these two fans can be used for the reversed operation. One can be used for inflow and others for the outflow of the air. Thus, if you want a window fan that can simultaneously perform two services, the window fans with two fans should be preferred. Both fans can be used for inflow or outflow simultaneously and can be used for alternative service depending upon the need of the user.
How to use a window fan
The usage of window fans is quite easy and can be quite useful if used in the right manner. There are certain norms which should be followed to keep the room temperature moderate by using a window fan:
- If you are using a window fan for your home, prefer the square ones instead of the circular or other shapes. The square fans offer a higher flow and are easy to install as most of the window frames are rectangular
- Secondly, it is suggested to use the even number of fans in your homes or offices. This is to ensure that the number of fans used for the inflow of air should be equal to the skyair’s outflow. Or, in another case, the number of inflow fans should be higher than the outflow fans.
- It is also suggested to install the inflow fans at the ground floor of the home and the outflow fans at the highest story of your home. This is because the air at the top is hotter as compared to the air at the ground level.
- Finally, make sure that the windows have a screen to prevent the insect and flies from entering the room from the window. Moreover, the window should not be closer to a noise source or garbage bin, which could affect the ambiance of your room.
So this device is good enough to maintain a moderate temperature in your homes or offices. At 60% less energy consumption, it is somewhat close to an air-conditioner, which can keep the temperature low. The reversibility function of window fans can also exhaust the hot air out, replacing it with the fresh one.
