For example, a fan with a CFM/Watt of 20 moves 20 cubic feet of air per minute for every watt of energy it uses.
- EER: This stands for energy efficiency ratio and is a measure of the cooling output of the fan relative to the energy it uses. The higher the EER, the more efficient the fan is. For example, a fan with an EER of 10 can deliver 10,000 BTUs of cooling per hour for every 1,000 watts of energy it uses.
- SEER: This stands for seasonal energy efficiency ratio and is a measure of the cooling output of the fan over an entire cooling season relative to the energy it uses. The higher the SEER, the more efficient the fan is. For example, a fan with a SEER of 20 can deliver 20,000 BTUs of cooling over a season for every 1,000 watts of energy it uses.
When comparing fans, it’s important to consider both their efficiency rating and their size. A larger fan with a lower efficiency rating may use more energy than a smaller fan with a higher efficiency rating, so it really depends on your specific needs and preferences.
Here is a comparison table of the CFM/Watt rating for common types of fans:
| Fan Type | CFM/Watt |
|---|---|
| Ceiling Fan | 50-90 |

The difference between AC and DC fans in power consumption
When it comes to fans, there are two main types: AC fans and DC fans. The main difference between these fans lies in their power consumption.
- AC fans: AC fans are the more common type of fan. They work by converting AC power from the mains supply to DC power using a rectifier. The rectifier converts the AC power to DC power by alternating the direction of the current several times a second, which creates a fluctuating current that can be used to power the fan motor. AC fans are typically less expensive and have a higher power consumption than DC fans.
- DC fans: Unlike AC fans, DC fans work solely on DC power, which means that they do not require a rectifier. They are also more efficient than AC fans, as they use less power to operate. This makes them the preferred choice for use in battery-powered devices. However, they are typically more expensive than AC fans.
While both AC and DC fans are widely used in various devices, the choice between the two depends on several factors such as power consumption, efficiency, cost, and application.
Below is a table that shows the power consumption of various fan sizes:
| Fan Size | AC Fan Power (Watts) | DC Fan Power (Watts) |
|---|---|---|
| 120mm | 7 | 2.5 |
| 140mm | 14 | 4.5 |
| 200mm | 24 | 7.5 |
As shown in the table, DC fans use less power than their AC counterparts. However, it’s worth noting that this is just a general comparison and actual power consumption may vary depending on the device and operating conditions.
