Cooling fans come in a variety of different styles and sizes. They use an attached motor to circulate air throughout the room, drawing hot air closer to the ceiling, which rises and gets pushed back down into the room by natural convection currents. They are the best to promote ventilation and should be used for drier, humid, warmer thermostats, etc.
This article is a step-by-step guide on how to determine whether a cooling fan is up to the task of providing you with enough airflow for your room.
Whether or not a cooling fan will cool the air with its central-air-conditioning properties, there are three necessary factors: the fan’s speed, how much area it is moving air through, and the amount of time it runs. In addition, two passive factors will also affect your results: room temperature and how close your ceiling fans are to each other.
What Factors Determine the Cooling Ability of Ceiling Fans?
- Exhaust Velocity: The exhaust velocity of a ceiling fan is the speed at which air is moved through the fan. A ceiling fan with an exhaust velocity of 100 mph will push air at the same rate as a 100 mph racecar. On the other hand, racecar racing can reach speeds up to 200 mph. If you want your ceiling fan to cool the air, then you should pick a pace that’s between 100-150 mph.
- Exhaust Area: The area of a room is measured in square feet, and there are 3600 square feet per linear inch. Therefore, an exhaust area of 1000 cubic feet per minute will move 1000 square inches of air at 100 mph. If you want to move more air, you’ll need an exhaust area that is more significant than 1000 square inches per linear inch. To do this, use a calculator.
- Temperatures: Room temperatures depend on the humidification and the weather outside, the electrical current from your home’s furnace or cooling system, any appliances running in your house (especially electric heaters), and whatever else is going on in the place at that time.
If you want to determine your room temperatures with a thermometer, then here are some steps for you:
- Find your average room temperature by averaging out hourly readings over a few days. If this isn’t possible due to extreme daily trends in temperature, then take daily tasks at about noon each day and average them out.
- Take the average ambient temperature of your room (in °c) and divide it by 16. It will be the number of degrees that your ceiling fan must move air for each given degree that the room temperature rises. You can use this calculator to determine how many degrees your ceiling fan must move air.
- If you want to get exact ambient ratio measurements, then use a thermometer to take 30 readings at varying heights in the room every 15 minutes while the ceiling fans are running.
- Use this chart to determine how many degrees you should run the ceiling fans at. For example, if your room temperature is 33°c but goes up to 34°c, then you’ll have to run your ceiling fans at +0.4°c.
How Do I Know Which Size Fan Works Best for My Space?
The first step is determining what type of room you’re trying to cool. The next step is finding the right size fan based on the dimensions of your room. Here are some things to consider when choosing a ceiling fan size:
Fan Size Square Footage x Linear Inches Per Sq Ft Fan Area
For example, if you live in an 800 sq ft apartment or house, then you need a fan that has a surface area of around 1600 square feet. This would mean that the fan needs to cover approximately 1.6 linear feet of wall space. You also need to make sure that the fan doesn’t block any windows or doors. Fans that don’t fit these requirements won’t work well because they won’t provide adequate ventilation.
Fans that aren’t sized correctly could cause problems such as overheating, noise pollution, and even fire hazards. So before buying one, check whether it fits into your home properly. Ceiling fans come in different sizes depending on their intended purpose.
Here are some tips to help you find the perfect ceiling fan size for your home:
1. Determine the square footage of your living space. To calculate the total square footage of your room, multiply the length times width. Then add those numbers together.
2. Find the height of your ceilings. Measure the distance between the top of your walls and the bottom of your roof rafters using a tape measure. Multiply this measurement by 2 to account for both sides of the room.
3. Calculate the volume of your room. Divide the sum of all three measurements by 3.
4. Use the following formula to figure out the ideal ceiling fan size for your room:
Square Feet Volume ÷ Height * Width
5. Make sure that the product’s specifications match yours exactly.
What Are the Best Fans to Cool a Room?
If you want your ceiling fans to be more energy efficient with better cooling systems, you should buy ones with a large exhaust/intake area of about 1400 square inches per linear inch of room. That means that if you had a high efficient 1000 square foot room, then the fan should be big enough to move at least 1400 larger of air through it (even if the room is not sealed).
