If your house is warm, it’s awful. Too much heat can make you feel uncomfortable. Fortunately, you can cool your stuffy rooms! The air flow can be improved. So, how to position fans to cool a room? How to maximize the breeze? There are some accessible tricks. Let’s observe and use them in our everyday life.
Can a Fan Blow Directly on Your Face?
Do you like this gentle breeze? In one respect, it makes us feel comfortable. We sweat and feel cooler. What happens when air moves over us, our bodies? A blowing fan speeds up the evaporation process. So, according to research, it helps to improve our thermal control.
Additionally, the best portable fan is beneficial in terms of air quality. It removes the harmful carbon dioxide from the buildings. Additionally, sleeping in a cold environment slows down aging. The sleep quality itself is improved. The body produces melatonin. Metabolic diseases, diabetes risks are decreased. Insomnia is prevented. Sleeping in a cold bedroom promotes reducing of the stress level!
Does a Fan Make a Room Cooler?
A fan is a device designed to cool down your room. Meanwhile, it features a motor that generates heat. Actually, it just makes you feel cooler by:
- Moving the air over your skin.
- Lowering your body temperature.
- Carrying hot air away from your skin.
Korean scientists even introduced a theory that a fan blowing can make a human heart stop beating. When metabolism slows down and the body temperature is below 95 degrees, it might be dangerous. Is it true? Quite naturally, it isn’t. Slight cooling can be fatal for neonatal infants only. Patients with accidental hypothermia are treated successfully nowadays. The body temperature of about 79 °F is not fatal.
What are the Possible Negative Issues?
A fan blowing on you might trigger:
- cold sore;
- muscle soreness;
- sinus trouble.
Thus, the best fan for sleeping is to be available in your bedroom. However, it is to blow not on you, but another direction. Otherwise, rapid air movement is not beneficial. It removes not only heat but also the moisture. It dries out your nasal passages and mouth.
How to Circulate Air with Fans?
Therefore, it’s recommended to keep the fan at a safe distance from your body. It’s better to install it not above your bed, but out of it. Additionally, if a filter is not available, dust is circulated together with air. It contains mold, allergens and bacteria. So, the best fans to cool a room come with air filters. This feature is really essential in the bedroom.
What are the common ventilation rules? The common problems of buildings in hot climate areas include high temperature, solar radiation, and humidity. Fortunately, the climate in Los Angeles is mostly dry in summer. Excessive moisture is typical only for the coastal regions of California.
So how can we deal with warm air? It is:
- Displacing from the lower stores.
- Moving upward.
- Rising and collecting on the top floor.
Quite naturally, the hottest place in a private building is in the attic. Additionally, the southern side of your house gets more sunlight than the northern walls. Arranging cross-ventilation, you are to consider these peculiarities.
Is It Better to Point a Fan Up or Down?
In California, keeping your house cool is a heavy task, for real. Intense heatwaves might become unbearable in summer and autumn. Low-rise buildings are at the greatest fire risk. How to deal with this heat? Cool roofs might solve the task. Featuring, highly reflective tiles, they absorb less heat than standard or traditional roofs.
Additionally, since 2020, all new residential houses in California have become green. They require solar panels on the roof. It lets the residents save on electricity and utilities. Energy-efficient air-circulation options are still essential. Air conditioning is powerful and functional but energy-intensive.
Ceiling fan is another essential option. It doesn’t replace your AC system but supplements it. Large, streamlined blades create powerful airflow. It improves air circulation in your room. In summer, it should run counterclockwise. It lets the blades push cool air down, lowering your room air temperature.
Changing their position angle, you may improve aerodynamics of the fan. Blades pitch matters. It modifies the tangential direction of motion, determining airflow force and amount.
Which Types of Fans Allow you to Charge the Airflow Direction?
There is a grip of useful and efficient cooling devices. Wall and window-mount units are space-saving and efficient. Coming with blades, they let you change the breeze intensity and drive. For example, you can point a window fan outwards. Commonly, it’s efficient, as the device itself generates some heat.
Additionally, you might use portable fans, including:
- stand devices.
These options would be necessary during extreme heat outbreaks. They meet your individual or local cooling needs. Which of them let you direct and control airflow? Side-to-side or up-and-down adjustments are not common. Typically, you’ll have to move the fan itself to direct the airflow.
Rotating side-to-side, oscillating devices provide even air circulation. If you need the special breeze amount and angle, opt for powerful, stand or pedestal devices. Very few devices are able to adjust vertical direction of airflow. They grant you ultimate comfort and coolness.
How to Keep a Room Cool that Faces the Sun?
Thus if your room is on the southern side, you should not open the windows. It wouldn’t help, especially in the daytime. Medium-colored window coverings are efficient to shadow or reflect the sun. What else works well? The list of elements includes:
- adjustable blinds;
- reflective film.
It would reduce the amount of sunlight that enters the room. Therefore, it won’t heat the surfaces up to the extent you can’t bear it.
How to Cool a Room without a Fan?
Do you live in a private house? Plant shady trees outdoors, around the windows. Are you allowed to make any building conversions? If so, install double-pane windows. Insulate the walls and paint them white. Light-colored house side reflects the sun. It absorbs less heat.
Adjustable awnings are also beneficial. Thanks to them, direct sunlight is blocked. Have you got an air conditioner? It’s a great relief! Just turn it on and set a favorable temperature. It should not be lower than 68°F.
Meanwhile, you still need to open windows sometimes. It’s better to do at nighttime. Early mornings can be pretty cool. Cross-ventilation can be arranged even without a fan. Just open two or more windows. Remove the covers in beforehand. If the wind is blowing, it promotes a cross-breeze. Don’t forget to close the windows in the morning. Curtains or blinds are to be drawn or closed during the day. Additionally, try to keep appliances and lights off. They generate heat.
How to Cool Down a Room with Two Fans?
Meanwhile, a ceiling fan only draws cooler air upward. Heat rises and the device pushes hot air downward. It creates a draft that makes you feel comfortable. However, in a living area that faces the sun, it might be not the most efficient. If the heat can’t escape from the room, space is not cooled.
A box fan does the job. It keeps the indoor air cool and eliminates odors. Quite naturally, the best way to cool a room with a box fan is to position it in front of a window. Arranging cross-ventilation at night:
- Open the windows.
- Position the fans.
- Create a wind tunnel.
A box fan can be placed on a table near the window. It is to be positioned just in front of it.
How to Get Cool Air from One Room to Another?
So, should the fan blow inwards or outwards? Cross ventilation is to remove the heat out from the house. Is your room connected to a hallway? It is commonly cooler than the room. So, the fan can be placed to push hot air out from the room.
Likewise, a window fan blows air out of the room. A box device can be turned in or out. It depends on the outdoor temperature. The fan is to face in, if:
- the temperature outdoors is cooler than indoors;
- the wind is blowing this direction;
- this side of the house is northern or shaded.
The other fan is to be placed in the opposite room. It draws hot air out of the house. A box fan can be positioned on a table or on the floor. An exhaust window fan can be used to remove the warm air.
Have you got a two-story house? Position several fans, both downstairs and upstairs. The device on the second floor is to face out. A fan in the downstairs window draws fresh air into the house.
How to Cool Down a Room Without Windows?
Can the spaces that have no windows be aired? They have to be. According to the California Building Code, all bathing fixtures are to be mechanically ventilated. Exhaust fans are to be installed in the bathroom, in the toilet, etc. They are designed to remove moist, odors and heat. Mildew forming is to be prevented for sure!
So, what are the acceptable exhaust rates? If the intermittent operation is assumed, it is to be not less than 50 cfm (cubic feet per minute). The continuous operation allows 20 cfm or higher rate.
Are you going to size a bathroom fan? Let’s try to do it together. Just consider the room size and its application.
|The Room Application
|The Room Size, sq. ft.
|CFM Ration of the Fan
|Medium-sized bathrooms with shower cubicles
|Bathrooms with jetted tubs available
|Large rooms with all fixtures and a toilet
Commonly, the rules allow the CFM rating that is higher than the sq. ft. number. According to the table. you get the minimum allowable CFM rating. However, it’s recommended to oversize the fan. If the ceiling is high, it is to be considered.
How to Cool a Room with a Tower Fan?
The device is taller than a box fan. It can be placed directly on the floor. Additionally, it rotates. So, position it in a corner. It will circulate the air through the room. If you’ve got 2 devices, place them in diagonal corners. A wind tunnel is created.
Actually, tower fans are great devices. They are:
The fan’s footprint is small. Therefore, it suits small rooms. The tower fans slide into the minimal spaces. The stylish design embellishes the room. Additionally, you can cool down a room fast with the fans. They distribute the air at 90 degrees. Additionally, tower fans commonly oscillate from left to right. Therefore, cooling and air circulation effects are maximized. The models that feature air ionization options are preferable.
How to Cool a Room with Ice and Fan?
It doesn’t matter which type of fan you use. This can be a table, box or tower device. It is to be portable, that’s all. So, place a pan or a tray of ice in front of the available fan. Bottles with cold water can be used instead. It’s less messy. However, ice is more efficient.
Air conditioners use a similar principle. They don’t melt ice. However, the refrigerant inside reduces the room temperature. It changes from vapor to liquid. This way, heat is removed. Thus, melting ice cools the air. The fan circulates it. It feels great.
I am sure you know, how to make your room look cool. A lot of design tricks are available. Curtains and pillows, wallpaper and lamps decorate it perfectly well. Use house plants and various accessories to personalize your living space. What about the fans? Some of them are decorative. The other ones are simple. All of them are functional. They help you to cool your room or the whole house. Just position them according to the wind direction and the airflow. They do the job.
