Use of Air Conditioners in high temperatures
As we experience persistently high temperatures, here are some simple actions for minimising energy consumption when using Air Conditioners:
- Block direct sunlight from entering the room.
- Turn off air conditioners and lighting when a room is expected to be vacant for longer than 15 minutes.
- Keep the AC temperature at an appropriate setting, typically not below 23℃ for cooling. Every additional degree requires some 6% more energy.
- Instead of lowering the temperature, consider directing the flaps in your direction.
- Set the fan speed to automatic for the most efficient airflow rate.
- When there are multiple AC units in the same space, avoid the Auto setting and ensure that they are all set to cooling.
- Wherever reasonable, reduce the use of AC and employ the use of fresh air and cross-ventilation.
C-SUM wishes you a pleasant summer.
