Air conditioners are a type of device that has become popular and familiar to everyone, even present in most families. However, how to use the air conditioner properly, save electricity while still being safe for the health of family members is always a question of interest to many people. Turning on the air conditioner at what temperature is one of them.
To answer this question, first of all, everyone needs to know that depending on the temperature inside the room compared to the ambient temperature, we have different answers to the above questions. However, normally, the air conditioner will cool most effectively when the condenser temperature is below 48°C and the room temperature is from 19°C or more.

According to experts, to save electricity when using air conditioning, you should set the air conditioning temperature at a difference of 6 to 10°C from the outside temperature.
This means that when the outside temperature is 40°C, turning on the air conditioner at 30°C will help save electricity while still providing enough coolness. But if you set the temperature below 25°C, the machine will have to operate at full capacity and will definitely consume a lot of electricity.
However, if the outside temperature is only about 30 - 35 degrees, you should set the air conditioner temperature to about 26 - 28 degrees to save electricity. If the air conditioner is set at 30 degrees, the air conditioner's hot block will turn on and off continuously. Every time the hot block starts, it will consume a large amount of electricity.
When you set the air conditioner at a low temperature of about 16 degrees Celsius, it will have to operate continuously at maximum capacity to bring the room to the desired temperature. If this is done continuously for a long time, it can increase monthly electricity consumption by 3 or 4 times compared to setting the temperature at a normal level of 25 - 27 degrees Celsius.
At the same time, according to experts from the US Department of Energy, the best temperature when using air conditioning is between 24 - 27 degrees Celsius. But this is the temperature that should be used during the day, and at night it should be at 28 degrees Celsius. The reason is because:
At night, the average temperature tends to decrease, and the body does not need to move as much as during the day. Therefore, the body will not sweat much, so if you keep the temperature the same as during the day, you will be more susceptible to catching a cold. In addition, it also makes you more likely to have cramps when going to bed.
In the evening before going to bed, adjusting the temperature to 28 degrees can also help save up to 10% of your electricity bill.
Vietnam Electricity Group (EVN) recommends that households using electricity for daily life should not set the air conditioner temperature below 26 degrees Celsius to save electricity. The information is included in a document sent by EVN to provinces and cities on promoting electricity saving in the 2023 dry season. In the announcement on the operation situation on May 15, EVN also said that it "hopes to receive the sharing and cooperation of people and customers" in using electricity economically, especially during peak hours at noon from 11:30 to 14:30 and in the evening from 20:00 to 22:00. |
