Traditional Ceiling Fan vs BLDC Ceiling Fan: A Comprehensive Comparison
When it comes to choosing a ceiling fan, there are several factors to consider. In this article, we will compare a traditional ceiling fan with no remote control, Wi-Fi, or smart home integration, consuming 75W of power, to a BLDC ceiling fan with downlight. The BLDC fan offers features such as color-changing options, remote control, immunity to power fluctuations, reduced noise, and compatibility with voice assistants like Alexa and Google. We will also calculate the energy consumption and cost savings for both types of fans.
Ceiling Fan Feature Comparison
| Feature | Traditional Ceiling Fan | BLDC Ceiling Fan with Downlight |
|---|---|---|
| Control Options | Wall switch only | Remote control, Alexa, Google Assistant |
| Smart Home Integration | N/A | Alexa, Google Assistant |
| Power Consumption | 75W | Generally lower (30-40W) |
| Fluctuation Resistance | Sensitive to voltage fluctuations | Stable operation in voltage fluctuations |
| Noise Level | Can be noisy, especially at higher speeds | Generally quieter due to BLDC technology |
| RPM (Revolutions Per Minute) | Standard RPM range (300-400 RPM) | Variable RPM, adjustable for efficiency |
| Air Delivery | Varies, generally lower compared to BLDC fans | Higher air delivery due to efficient blade design |
| Lighting Features | N/A | Downlight with color-changing options |
| Ease of Installation | Standard installation | Standard installation (no additional wiring for lights) |
| Durability and Lifespan | Standard lifespan | Longer lifespan due to efficient BLDC motor |
| Initial Cost | Generally lower | Higher due to additional features and technology |
| Energy Consumption (per hour) | 0.075 kWh | 0.030-0.040 kWh (assuming 30-40W) |
| Energy Cost (per hour at 8 INR/unit) | 0.60 INR | 0.24-0.32 INR |
| Savings (per hour) | N/A | 0.28-0.36 INR |
| Savings (per day) | N/A | 6.72-8.64 INR |
| Savings (per month) | N/A | 201.60-259.20 INR |
| Savings (per year) | N/A | 2,419.20-3,110.40 INR |
Energy Consumption and Cost Savings
In India, electricity is measured in kilowatt-hours (kWh). Let's calculate the energy consumption and cost savings for both types of fans, assuming an electricity cost of 8 INR per unit.
Traditional Ceiling Fan
The traditional ceiling fan consumes 75W of power. To calculate the energy consumption per day, we multiply the power by the number of hours used. Assuming the fan is used for 16 hours a day:
Energy consumption per day = 75W * 16 hours = 600Wh = 1.2kWh
To calculate the monthly consumption, we multiply the daily consumption by 30:
Energy consumption per month = 1.2kWh * 30 days = 36kWh
And finally, the yearly consumption is obtained by multiplying the monthly consumption by 365:
Energy consumption per year = 1.2kWh * 365 days = 438kWh
To calculate the cost savings, we multiply the yearly consumption by the electricity cost:
Cost savings per year = 438kWh * 8 INR = 3504 INR
BLDC Ceiling Fan
The power consumption of a BLDC ceiling fan varies, but it is typically lower than 75W. eff4 Prosper 5 star bldc fan consumes 30W of power. Using the same calculations as above:
Energy consumption per day = 30W * 16 hours = 240Wh = 0.48kWh
Energy consumption per month = 0.48kWh * 30 days = 14.4kWh
Energy consumption per year = 0.48kWh * 365 days = 175.2kWh
Cost savings per year = 175.2kWh * 8 INR = 1401 INR
Conclusion
In summary, the comparison between a traditional ceiling fan and a BLDC ceiling fan reveals several advantages of the latter. The BLDC fan offers remote control, Wi-Fi/app control, compatibility with voice assistants, color-changing options, immunity to power fluctuations, and reduced noise. Additionally, the BLDC fan consumes less power, resulting in significant cost savings. Over a year, the savings can amount to 2100 INR, compared to the traditional fan's consumption cost of 3500 INR. Minimum Lifespan of a Ceiling Fan is 5 years and goes as high as 10 - 12 years. At present the cost difference between a traditional fan and BLDC fan is 25-40%, which can be very much covered within first year itself. Considering these factors, the BLDC ceiling fan emerges as a more efficient and technologically advanced choice for modern homes.
Please note : the energy consumption values are approximate, and actual values may vary based on specific fan models and usage patterns. The savings calculations are based on the assumption of continuous operation for simplicity; actual savings may vary depending on individual usage patterns.
