Some tips for your ac.
Here are some tips for saving on air conditioning electricity costs:
To save on electricity, I set my air conditioner to dehumidification mode (DRY mode), keeping the room's humidity between 50-60%.
On the remote control, I set the temperature to 26°C, but the actual room temperature is 24.3°C, with a humidity of 47%. Normally, my room's humidity is around 70%. In Malaysia, the ideal, fresh, and healthy humidity range is between 50-60%.
This means my air conditioner is working well and is suitable for the size of the room. The optimal sleeping temperature is 24°C or 25°C. Even if you set the remote control to 16°C, you might only reach about 19°C, but the compressor will keep running, leading to a spike in electricity costs.
To save energy, set the remote control to dehumidification mode (DRY mode, represented by a water droplet symbol instead of a snowflake) and set the temperature to 24°C or 25°C. If it still feels uncomfortable, you can first set the remote to 22°C in cooling mode (COOL mode), and then switch to dehumidification mode (DRY mode).
Dehumidification mode can save approximately 50% of electricity compared to cooling mode (COOL mode) because the compressor operates at a lower frequency.
For reference, the electricity cost per hour for an air conditioner is approximately:
- 1 HP (900 watts) - 20 sen per hour
- 1.5 HP (1.2 kW) - 30 sen per hour
- 2 HP (1.9 kW) - 40 sen per hour
- 2.5 HP (2 kW) - 50 sen per hour
Hope this helps!
