When it comes to air conditioning, you may focus on wind speed, temperature changes and other indicators that we directly feel. In fact, energy efficiency is also important for air conditioning. At present, the domestic air conditioners on the market are mainly three-level energy efficiency, two-level energy efficiency and one level energy efficiency. Among them, the first level energy efficiency is the most energy-saving, while Xiaomi's "huge power saving" is called super first level energy efficiency, so how much power will be saved? Let's take a look at the evaluation of Xiaomi air conditioner.
Appearance and installation: simple design, fashionable and versatile
The exterior design of Xiaomi air conditioner adopts the consistent simple style of Xiaomi. Its indoor unit adopts pure white color matching, equipped with circular display screen, which looks quite simple. Such design can also match the decoration style of most families. No matter in the simple European, Chinese or western style, Xiaomi air conditioner can be well integrated into the environment.
The display screen of Xiaomi air conditioner can display the set temperature, and the temperature is accurate to one decimal place, which is convenient for users to control the indoor temperature more accurately.
In terms of outdoor unit, we can see a big millet logo, which is also protected by a fine metal mesh at the fan blade. In the back and side of the outdoor unit, protective nets are added to prevent sundries from entering the interior of the machine body, so the protection of the machine is in place.
It is worth mentioning that a protective cover is also added at the pipe interface of the outdoor unit to bring more comprehensive protection.
In terms of installation, after purchasing millet air conditioner, there will be a special person to contact and arrange a master to install it on site. If the installation is normal, the installation is free. If you need to drill or extend the pipeline at home, you need to pay additional installation costs.
The design of 13 key remote control of Xiaomi air conditioner is also very simple. The operation mode, temperature and wind speed will be displayed on the screen. After pressing the key, the air conditioner will have a sound prompt. The temperature adjustment of Xiaomi air conditioner can be set to one decimal place, which is very accurate.
Power consumption test: super energy efficiency and power saving
Data display of power detector
After installation, we will test the power consumption of Xiaomi air conditioner. The test equipment we choose is 16A power detector, which can display the real-time power of the air conditioner and record the power used. We will record the power consumption of the air conditioner through this equipment.
Test 1: heating at 26 ℃ for one hour
Indoor area: 13 ㎡
Room temperature: 16.3 ℃
After the test, under the heating mode of 26 ℃, the power consumption of millet air conditioner in an hour is 0.68 degrees. According to the current electricity price of 0.4883 yuan / degree in Beijing, the total cost of the test is 0.332 yuan, or more than 30 cents. Because the power of the air conditioner is high at the beginning of startup, the power of the air conditioner will gradually decrease with the rise of temperature, so the average power consumption of the air conditioner will be lower if it is operated for a long time.
Millet air conditioner supports frequency conversion function. When it is just started, the power will be high, so as to realize the room temperature rise as soon as possible. When the room temperature rises close to the set temperature, the power of millet air conditioner will be reduced, so as to save power.
Test 2: energy saving mode heating for one hour
Indoor area: 13 ㎡
Room temperature: 19.3 ℃
Millet air conditioner supports the energy-saving mode. In the energy-saving mode, the heating temperature of the air conditioner is limited to 25 ℃.
Through the data comparison, we can see that in the energy-saving mode, the real-time power of millet air conditioner is lower than that of the ordinary mode, which is why the energy-saving mode is more energy-saving. However, because the energy-saving mode reduces the power of millet air conditioner, the energy-saving mode is slower than the ordinary mode in terms of the speed of indoor temperature rise.
In the energy-saving mode, the cost of one hour heating of millet air conditioner is 27 cents.
We also make the data of common mode and energy-saving mode into a curve chart, which is convenient for you to compare and view.
Test 3: refrigeration at 20 ℃ for one hour
Indoor area: 13 ㎡
Room temperature: 25.1 ℃
At present, the daytime temperature in Beijing is only about 12 ℃, so before the test, we first raise the room temperature to 25 ℃, and then lower the temperature through millet air conditioner. If the outdoor temperature is more than 30 ℃ in summer, the cooling power of air conditioner will increase and the power consumption will increase.
After one hour's test, we can see that when the indoor temperature drops to 20 ℃, the air conditioner will be in a very low power consumption state, with a power of only 11.5w, and the final one hour's power consumption is only 0.068 degrees, which costs 0.03 yuan, that is, 3 cents.
Test 4: energy saving mode cooling for one hour
Indoor area: 13 ㎡
Room temperature: 28 ℃
In the energy-saving mode, the cooling temperature of Xiaomi air conditioner will be limited to 26 ℃, we will raise the room temperature to 28 ℃, when the refrigeration is started, the real-time power of Xiaomi air conditioner reaches 328w, but with the room temperature approaching 26 ℃, the power of air conditioner immediately drops to about 11.5w. During the whole test process, Xiaomi air conditioner is in a very low power refrigeration state. Finally, the electric charge of Xiaomi air conditioner in the energy-saving mode is 0.01 yuan, that is, 1 cent.
Note: during the test, the temperature in Beijing is as low as 12 ℃, so it will affect the test cooling data. In summer, the power consumption of the cooling function of millet air conditioner will be higher than the test data.
Performance test: comparable to the temperature control performance of high-end air conditioner
The performance of air conditioning is mainly reflected in the speed of refrigeration or heating. Whether it can quickly change the indoor temperature? Based on this, let's test the performance of millet air conditioning.
Data display of air volume and temperature test equipment
In terms of performance test, we will use instruments to record the air volume, air temperature and the time from room temperature to set temperature of Xiaomi air conditioner.

Noise and wind speed test
Noise test equipment data display
In noise test, we set the mode of Xiaomi air conditioner as 30 ℃ heating and 16 ℃ refrigeration respectively, and record the noise volume at the air outlet of the air conditioner and 2m away from the air conditioner, the wind speed noise of Xiaomi air conditioner from level 1-6 and the noise in energy-saving mode.
Indoor noise: 38dba
Other selling points: intelligent manipulation and cleaning is easie
It is not hard to see through the test that Xiaomi air conditioner performs well in terms of power consumption. In fact, in addition to power consumption, the function highlights of Xiaomi air conditioner itself are also worthy of attention.
First of all, millet air conditioning supports the function of making hot and cold air. When we start heating mode in winter, millet air conditioning will start outdoor unit first, and indoor air will come out after the temperature rises. In this way, all the hot air will come out to avoid cold air entering the room.
Video demonstration of Xiaoai operating Xiaomi Internet air conditioner
In addition, Xiaomi air conditioning supports Xiao Ai through the voice control, after the network can be through Xiao Ai to carry on the voice control to the air conditioning. If there is a millet temperature and humidity sensor at home, the millet air conditioner can also be linked with the temperature and humidity sensor. The user can set the indoor temperature and humidity of the air conditioning self-starting. When the indoor environment reaches the value set by the user, the air conditioning will start automatically.
