We often think that when using air conditioning, we have to close all the doors tightly. This way, it ensures coolness and protects the machine, but this method is not entirely correct.
Why shouldn’t you close the door when turning on the air conditioner?
When turning on the air conditioner, we usually close all the doors tightly to prevent cold air from escaping, helping to save electricity. However, many people do not know that the air inside a closed air-conditioned room is usually 2-5 times more harmful than outdoor air. If you continuously use the air conditioner in a small room with closed doors, the room will become stuffy, and the users will feel suffocating, heavy, as if there is no oxygen to breathe. Especially for the elderly and children, the risk of harmful effects on health is even higher.
To minimize this, you can create small gaps in the room for air circulation, install additional ventilation fans; choose air conditioners with air filtering functions, which not only cool the room but also ensure health.
Experts recommend that every 30 minutes, you should open the door of the room to let the room “breathe” once. This will help the air in the room to be “refreshed” and avoid the uncomfortable feeling for both the mind and the health of the people inside.
Why shouldn’t you close the door when turning on the air conditioner?
During the day, you should not stay in an air-conditioned room continuously for 4 hours as it will make you dependent on higher-than-normal conditions and reduce your adaptability. Therefore, every 2-3 hours, you should go outside to experience the normal temperature, change the air and adapt to the outside temperature.
In addition, when the temperature drops (such as in the evening, when it rains…), you can turn off the air conditioner and open the door of the room to let the air circulate.
Common mistakes when using air conditioners
Leaving the air conditioner on all night
At night, when your body doesn’t require such low temperatures, even cold like during the day. Try to turn off the air conditioner temperature when sleeping or turn it off 1-2 hours before sleep. That way, the operating time of the machine will be reduced.
Setting the air conditioner temperature too low
26 degrees Celsius is the ideal number for running the air conditioner at its most efficient level. It’s similar to a car driving on a flat terrain without accelerating up a slope or over rough terrain, just running steadily.
Turning off the air conditioner when the room is already cool
To save electricity, many people have a habit of turning off the air conditioner when the room is cool and turning it back on when the room temperature rises! There are cases where the air conditioner is turned on for only 15 minutes, and when the room becomes slightly cold, it is turned off, then turned back on after 15 minutes.
In fact, this is a mistake of “overthinking,” because when restarting, the air conditioner consumes a lot of energy. Constantly changing between hot and cold states also makes your body uncomfortable.
The most reasonable way is to maintain the room temperature at a stable level, instead of turning off the air conditioner completely. The ideal temperature difference between the air-conditioned room and the outside temperature is about 7 degrees Celsius.
Only using the air conditioner without using the fan
We should use fans to circulate cool air evenly throughout the room. They consume less energy than air conditioners, so using fans instead of air conditioning when it is not too hot is always a great idea.
