Which type of fan gives more air?
by Sam Smith Search Engine MarketingCeiling fans are an inevitable part of a building. It works by converting electrical energy into mechanical energy which moves the blades of the fan creating airflow. This can keep you comfortable even when the temperatures are soaring outdoors. This is because the ceiling fan cools by moving air over your skin and prevents you from sweating profusely in a hot and humid climate.
Two important measures
The two important measures that you would have to consider when you are buying a ceiling fan is its efficacy and efficiency rating. Efficacy is the rating that indicates the output measured in cubic feet per minute (cfm). The CFM tells you how well the ceiling fan moves air within the room. The efficiency refers to the input that is required to produce the output. In other words, it is the amount of electrical energy or watts required to produce the airflow that is adequate to keep you cool in a room. A good fan is one that would give more than 100cfm per watt. A poor one has a CFM of 30 per watt. You can look for the CFM measures and watt measure mentioned on brochures, catalogs, and the package of the ceiling fan to estimate the efficacy and efficiency of the fan.
Bigger is better
Generally, fans with longer blades have better efficacy than those with shorter blades. This does not mean that fans with shorter blades are worthless. They would not be manufacturing ceiling fans with shorter blades if they were of no use at all. Having a fan with a long blade for a smaller space would counter the effect. Therefore, it is important to choose the fan with the right blade length. That is when ceiling fans with shorter lengths are handy.
Speed
If you want to understand the fan speed, you have got to consider a factor called RPM or Rotations per minute of the blade. The standard 48” 1200mm blade fan would run at 300/350 RPM. The high-speed fans have an RPM of 380-390. RPM is an important consideration because of how fast the ceiling fan spins generally influence the amount of air it produces. Some standards have been laid out regarding the maximum RPM that the ceiling fans can have. It has been drafted based on the blade span and the thickness of the blade. The ceiling fans with thinner blades usually have lower RPM compared to those with thicker blades. That is for a blade span of 24, the maximum RPM that is permitted for a 3/16” thick blade is 509 while the RPM for a 1/8” thick blade is 382.
You have fans with two blades to up to those with 9 blades. In general, the three, four, and five-blade fans are used often. They are noted for their efficacy and efficiency ratings. However, in the case of small rooms, outdoor use, etc, you might have to go in for the other options. You may take the help of the experts to decide which type of fan would be suitable for your requirements.
The ceiling fans are designed to give air. But, you need to consider the above-mentioned factors and choose the right one for the space in which you intend to use it to ensure good airflow.Sponsor Ads
