Electricity Saving Tip p1

Since its already summer and its very hot in Manila, I think its about time for us to think on how to save electricity since we are experiencing global crisis. I found this useful tips from Meralco.

Electric Fan Saving Tips

  • Choose the right type of fan to cool down a particular place. Desk fans are the most effective fans for small rooms. Stand fans, on the other hand, are best for medium-sized rooms. They offer great flexibility in providing the cool breeze you want because of their adjustable height levels. For large or spacious rooms, consider using ceiling fans. Ceiling fans have larger blades compared with other types of fans. The longer the blades, the more air they can push around. Ceiling fans are very efficient in stirring the cooler air along the floor to provide the necessary cooling in a room.
  • Get the right size of ceiling fan for your room. The sizes of a ceiling fan commonly range from 34” to 56” in diameter. Generally, a 36” fan is suitable for rooms that measure up to 9’x12’. A 48” fan is practical for rooms up to 12’x15’, and a 56” fan suits rooms larger than 12’x15’. A long and narrow room may require two fans for effective air circulation. Undersized fans are not effective to use because these would not provide you the cooling requirements and comfort that you need.
  • Properly set your fan speed according to your cooling needs. The speed level setting of a fan is directly proportional to its energy consumption. The faster your fan blades rotate the more energy your electric fan consumes.
  • Use the oscillating feature of your desk fan to efficiently provide the cooling effect you need. Lock the oscillator when fan is needed in one direction only.
  • Turn off your electric fans when no one is using it.
  • Perform regular maintenance to keep your electric fan running more efficiently. Maintenance activities can save up to 30% of fan energy.
  • Clean your electric fans regularly, to keep them running efficiently. Remove the dust accumulated at the fan blades, motor housings, and grills as it reduces the air current generated by the fan. Cobwebs, dust and other forms of impurities piling up at the motor’s cover prevent air to naturally provide the cooling needed by the motor or heat produced by the motor to be released. This causes additional heating of the motor’s windings, which leads to more consumption of energy.
