Which saves electricity, 26 degrees or 28 degrees? Why?

Air conditioning can be said to be a "good helper" in home life, and it is also one of the indispensable household appliances to provide a comfortable living environment. In the use of air conditioners, people are most concerned about how to save electricity while ensuring normal operation. After all, the electricity saved is very real. According to relevant data, 26℃ is the relatively energy-saving temperature setting of air conditioners, but 28℃ is the most ideal energy-saving temperature value for many people in their home life. So, which is more energy-saving to turn on the air conditioner at 26℃ or 28℃?

Which is more energy efficient, 26℃ or 28℃? I want to know which is more energy-saving when turning on the air conditioner at 26℃ or 28℃. I think it is necessary to analyze it in detail from three aspects: fixed frequency and frequency conversion, running time and temperature energy-saving rate, so as to get a comprehensive answer.

First, fixed frequency and frequency conversion.

Air conditioning can be divided into fixed frequency and variable frequency, which is also the key factor affecting power saving. As an air-conditioning business, it also takes this item as the sales focus to guide consumers, and also clearly tells consumers that frequency conversion will save more electricity.

⑴. Fixed-frequency air conditioner: The so-called fixed-frequency air conditioner means that the compressor of the air conditioner has been running for a long time, so in the process of use, the external machine is basically running all the time, which will naturally generate more electricity bills. But for people who can use fixed-frequency air conditioners, it is possible for fixed-frequency air conditioners to save electricity than frequency conversion, but this is a minority after all, and there are certain preconditions that not everyone can do.

⑵. Variable-frequency air conditioning: The so-called variable-frequency air conditioning means that the air conditioner runs at high speed after the set temperature value, so that the room can quickly reach the set temperature value. When the indoor temperature reaches the set temperature, it will naturally turn to low speed operation. At this time, it can not only ensure the indoor temperature, but also achieve a certain power saving effect. This is also the reason why air-conditioning businesses are pushing inverter air conditioners now, and consumers recognize inverter air conditioners more.

Extended analysis: In the same environment, the power consumption of fixed-frequency air conditioners will exceed that of variable-frequency air conditioners at 26℃, mainly because the fixed-frequency air conditioners can't automatically adjust and naturally can't reduce energy consumption. But under the same conditions, both fixed-frequency and variable-frequency air conditioners are more energy-saving than 26℃. After all, the temperature difference between 28℃ and outdoor is smaller, which is relatively easier to realize and naturally more energy-saving.

Second, the running time depends on the running time of the air conditioner at 26℃ or 28℃. Because of the different running time, the electricity consumption will also be different.

⑴. There is basically no difference in the power-saving effect of air conditioning running for a short time: if air conditioning is used for a short time in summer, it will only take one or two hours a day. At this time, whether the air conditioner is turned on at 26℃ or 28℃, there is basically no difference in the convenience of saving electricity between the two. This is mainly because the air conditioner has just started high-speed operation, and it is necessary to quickly reduce the indoor temperature to the set temperature. At this time, whether it is started at 26℃ or 28℃, and whether it is fixed frequency or fixed frequency, it is running at full horsepower. When the indoor temperature reaches the set temperature value, it is basically not used, so there is no difference. Neither of them has achieved the performance of reducing energy consumption because there is not enough time to show it.

⑵ Running the air conditioner at 28℃ for a long time is more energy-saving: For using the air conditioner for a long time in hot summer, it is obvious that turning it on at 28℃ is more energy-saving than turning it on at 26℃. This is mainly because using air conditioner for a long time can reach the temperature of 28℃ faster and can also maintain the temperature of 28℃ faster. At the same time, the difference between the temperature value of 28℃ and the indoor temperature value is also small, which will naturally save more electricity. At the same time, sleeping at 28℃ is more comfortable than sleeping at 26℃, which is one of the main reasons why many people turn on 26℃ at the beginning of air conditioning operation and adjust the temperature to 28℃ before going to bed.

To sum up, under the same conditions, turning on the air conditioner at 28℃ saves 20% electricity compared with 26℃, which is relatively more energy-saving.
