Should the temperature be adjusted and how long should it be used to save electricity for the air conditioner?
1. How much temperature is reasonable?
Many families are used to keeping it at 22.23 degrees Celsius, or even the lowest (usually 15-16 degrees Celsius), if it is cold, cover it with a blanket to make it easier to sleep. However, in fact, lying on a mattress, covering with a blanket, and turning on the extremely low air conditioner is very wasteful. While just increasing the temperature by about 1 degree Celsius can save up to 7-10% of power consumption.
Accordingly, to suit the Vietnamese climate, households should keep the air conditioner at 27-28 degrees Celsius, or even 29 degrees Celsius at night, which will help save maximum electricity bills without affecting much to the environment. health.
It should be noted that during the peak of hot days, if the room temperature is turned on too low, but often have to go out and in, it will cause thermal stress, causing colds or even heat stroke.
2. Should the fan be turned on when using the air conditioner?
This is a question asked by many households, whether turning on the fan when using the air conditioner consumes more electricity, or saves more electricity. In fact, the answer depends more on the conditions of the room, such as whether your room is directly exposed to sunlight, is it located in the attic, is it large, and has many obstructions? air circulation or not.
However, in general, turning on the fan when using the air conditioner is reasonable, and does not consume more electricity. The reason is because the fan will help circulate cool air in the room better, helping the places with hot air to be cooled, and thereby reducing the work load on the air conditioner.
If you pay attention, you will see that the air conditioner has a diffuser and a fan to help push cool air over a large area. However, the wind power and operating range of the air conditioner cannot be as effective as an electric fan, especially a ceiling fan. Therefore, it is recommended to use a combination of air conditioners and fans at all times to optimize the capabilities of both.
3. How many hours should I use the air conditioner per day?
The actual frequency of using the air conditioner depends greatly on the outdoor weather conditions. On hot days, temperatures up to 39, 40 degrees Celsius like the recent heat wave, you may have to turn on the air conditioner for 15-20 hours a day. On cooler days, frequency can be reduced to 8-10 hours depending on conditions.
To answer the question on too hot days, can the air conditioner be turned on continuously 24/24 or not, the expert in the refrigeration field said: “It is necessary to distinguish between inverter air conditioners and inverters. and old-fashioned, non-inverter air conditioners.”
Accordingly, the inverter air conditioner can run continuously from the time the machine is turned on until the machine is turned off. Old-style air conditioners, without inverters, when running, when resting (ie, running continuously but with a break time). In the hot days, the air conditioner without inverter can work continuously 24/24h. However, when running continuously, the life of the machine will decrease. When the machine is rested, the life of the machine will certainly be longer.
Therefore, we should take advantage of times when the air is cool like early morning, or when there are thunderstorms to turn off the air conditioner to rest.
Note that using the air conditioner for too long with both adults and children is not good, should not turn on the air conditioner and sleep for more than 5 hours because this will affect health.
4. Should I turn off the air conditioner every time I leave the room?
Although the air conditioner should not be used continuously for a long time, you should also not turn it off when leaving the room for a few minutes. The reason is because the stage that makes the machine work the heaviest is at the beginning, ie cooling a hot, stuffy room.
This is true when the outdoor temperature is very high, causing even 5-10 minutes to turn off the air conditioner will cause the temperature in the room to change significantly, and when turned back on, the air conditioner must cool from the beginning with the highest capacity. .
5. Note when using air conditioners for pregnant women and babies
For infants, the ideal temperature is around 28 – 30 degrees Celsius. Older children may have lower temperatures. This is also true for pregnant women, because the temperature should not be turned on too low as it will affect health.
Besides, users also need to pay attention to turn on more fans to circulate air. However, if there are infants, it is necessary to avoid the wind from blowing directly on the child. The room should also not let the humidity be too high, and especially do not use a humidifier, misting fan, … in an air-conditioned room. Just put a basin of water in the room or dry a wet towel soaked in water is enough.
