Switching from Cool to Dry mode can save tenfold on air conditioner electricity consumption.
1. Tips for maximizing air conditioner energy efficiency
Switching from Cool to Dry mode can save tenfold on air conditioner electricity consumption.
Select the “dry” mode
Switch from Cool (right, with snowflake) to Dry (left, with water drop) mode to save electricity.
Use the controller to switch from “Cool” (cool, indicated by a snowflake) to “Dry” mode (dehumidify, indicated by a water drop). This simple action reduces air conditioner power consumption by tenfold, preventing thermal shock as room temperature remains above 23°C without significant fluctuations with outdoor temperature.
In practice, this method saves electricity because in Cool mode, the air conditioner extracts heat from the room to expel it outside, lowering the temperature and cooling the indoor air. The electricity consumption for this operation is considerable. Meanwhile, in Dry mode, the air conditioner removes moisture from the room, providing fresher and drier air. This mode consumes less electricity than cooling mode.
Maintain room temperature above 25 degrees Celsius. According to Bijli Bachao, an Indian website specializing in electricity-saving tips for homes and offices, the closer the air conditioner temperature is to the natural temperature, the less electricity it consumes. To cool the room, it's advisable not to set the temperature below 25 degrees Celsius. You can calculate the energy-saving formula when increasing the air conditioning temperature as follows: Percentage savings = (new temperature - old temperature) : (outside temperature - old temperature) x 100. For example, if the outside temperature is 37 degrees Celsius and you increase the air conditioning from 20 to 25 degrees Celsius, you will save: (25 - 20) : (37-20) x 100 = 29.4%. Note: This formula is calculated assuming poor insulation between the room and the outside, so the room temperature is equivalent to the outside temperature in non-air-conditioned conditions.
Many people believe that maintaining the same air conditioning temperature will save electricity. This is entirely wrong. According to the recommendations of the US energy-saving agency, the simplest way to save electricity is to increase the temperature when you're not in the room. When you return, you may feel hot for a few minutes, but the heat dissipated is not significant enough to require your air conditioner to start cooling from scratch. Always set the air conditioner to the highest temperature to save the most electricity. Even a slight adjustment in temperature can increase costs. The US Department of Energy recommends a room temperature of 25 degrees Celsius. Additionally, you can use other methods such as turning off some electrical devices indoors to avoid further temperature increase.
The placement of the outdoor unit can also affect energy consumption: Heat from the sun will reduce the efficiency of the air conditioner, so the outdoor unit should not be placed in excessively hot and confined spaces.
Avoid running the air conditioner 24/7, even on the hottest days. In fact, running the air conditioner continuously throughout the day can be harmful to your health because the air is not circulated and the room humidity is significantly reduced. Therefore, turn off the air conditioner and use a fan during less hot times of the day. This not only helps to ventilate the room better but also significantly saves electricity. If combined with a fan and a cool water bowl, it will help enhance the effectiveness of use because the fan helps circulate cool air in the room.
