How much electricity does an inverter air conditioner use each month? How much can you save compared

Man, this question depends on how big your room is, whether the room is well insulated, and the temperature and room temperature you set, and if these conditions require the air conditioner to run at full capacity, it will not save electricity. If you can, talk about it.

A: 20% 30% energy saving than conventional air conditioners

Note: Inverter air conditioners require the air conditioner to run continuously to achieve the purpose of power saving.

Classification and reasons for power saving:

1) AC inverter air conditioner adopts AC inverter compressor, and the voltage conversion is adjusted twice, because compared with the fixed-frequency compressor, there is no starting capacitor, so the circuit loss is reduced, so as to achieve the purpose of power saving.

2) DC inverter air conditioner adopts DC digital variable speed compressor, which only undergoes one voltage conversion, similar to DC motor, removes the copper loss in the circuit, and can save 18-40% of electrical energy compared with AC inverter, thus reflecting the superiority of DC inverter technology.

Principle: Inverter air conditioner is based on ordinary air conditioner, which selects a special compressor for inverter, and adds a variable frequency control system. Its basic structure and refrigeration principle are exactly the same as those of ordinary air conditioners.

The host of the inverter air conditioner is automatically continuously variable speed, which can automatically provide the required amount of cold (heat) according to the room situation; When the indoor temperature reaches the desired value, the air withering host will operate at a constant speed that can accurately maintain this temperature, so as to achieve "non-stop operation", so as to ensure the stability of the ambient temperature.

Features of inverter air conditioner:

The starting current is small, the speed is gradually accelerated, and the starting current is 1 7 of the conventional air conditioner

There is no Mao Zhaoqing disease of sudden cold and heat, because the inverter air conditioner gradually reduces the speed as the temperature approaches the set temperature, gradually reaches the set temperature and maintains a low-frequency operation balanced with the loss of cooling capacity, so that the indoor temperature remains stable;

The noise is lower than that of conventional air conditioners, because the inverter air conditioner uses a double-rotor compressor, which greatly reduces the cyclotron unbalance, so that the vibration of the outdoor unit is very small, about 1 2 of the conventional air conditioner

The speed of cooling and heating is 1 2 times faster than that of conventional air conditioners. The inverter air conditioner adopts electronic expansion throttling technology, and the microprocessor can control the opening degree of the valve according to the information collected by the temperature sensors installed in the inlet and outlet of the expansion valve, the suction pipe of the compressor, etc., so as to achieve the purpose of rapid cooling and heating.

Specific power saving analysis:

For example, if the air conditioner is used for three months per year, 30 days a month, and runs for an average of 8 hours a day, the refrigeration operation time is 960 hours, and the average air conditioning power is 2000W, during the refrigeration period, the use of fixed-speed 5-level air conditioning (eer = total power consumption is 1920 degrees, if the current Shanghai standard 5-level inverter air conditioner (eer =, the total power consumption is 1510 degrees, and the power saving is about 410 degrees, each unit saves only more than 150 yuan per year. However, at present, the ** of inverter air conditioner is more than 1,000 yuan more than ordinary air conditioner**!

In addition, taking northern cities as an example, many areas have heating facilities in winter, and the season of using air conditioning is only about three months a year, and most of the time the air conditioner is idle, and the advantage of inverter air conditioning is not obvious.

What is an inverter air conditioner?

The host of the inverter air conditioner is automatically continuously variable speed, which can automatically provide the required amount of cold (heat) according to the room situation; When the indoor temperature reaches the desired value, the air withering host will operate at a constant speed that can accurately maintain this temperature, so as to achieve "non-stop operation", so as to ensure the stability of the ambient temperature.

What is a fixed-frequency air conditioner?

The grid voltage in China is 220 volts and 50 Hz, and the air conditioner that works under this condition is called a fixed-frequency air conditioner. Because the power supply frequency cannot be changed, the compressor speed of the traditional fixed-frequency air conditioner is basically unchanged, and the compressor is constantly "turned on and stopped" to adjust the indoor temperature, which is easy to cause the room temperature to be cold and hot between one turn and one off, and consume more electric energy. Due to the large temperature difference between the room temperature and the set temperature within 1 hour of the inverter air conditioner, the refrigeration is quickly adjusted with high power and high frequency operation, so the power consumption is large for a period of time when the machine is just turned on; If the test consumes electricity for a long period of time, the inverter air conditioner will save more power than the fixed-frequency air conditioner with the same number of horses, but if the environment is special (such as poor room insulation effect) and the load is always large, the inverter air conditioner may consume more power than the fixed-frequency air conditioner with the same number of horses.

The part of the air conditioner that consumes the most electricity is the compressor. The inverter air conditioner has added an inverter that can be used to adjust the compressor speed than the ordinary air conditioner, and the speed of the inverter air conditioner compressor will slow down according to the decrease in the indoor temperature, while the ordinary air conditioning compressor has been running at the maximum speed, so under certain circumstances, the inverter air conditioner is more energy-saving than the ordinary air conditioner. But why is it that the actual use is often not as energy-efficient as the merchant says?

That's because when the inverter air conditioner and the ordinary air conditioner start up, because the indoor temperature does not reach the set temperature, they are running at the maximum power. When the indoor temperature reaches the set temperature, the inverter air conditioner reduces the running speed of the compressor through the inverter, and of course, the power consumption drops sharply. After the indoor temperature reaches the set temperature, the ordinary air conditioner cannot adjust the speed of the compressor, so it must turn off the compressor, and its power consumption is lower than that of the inverter air conditioner.

When heating, an average of about one kilowatt-hour of electricity is required. The power consumption is mainly to look at the power of the compressor, the power difference of the compressor = the energy consumption ratio of cooling capacity, and the energy consumption ratio of the general air conditioner is greater than 3

A Gree inverter air conditioner can use one kilowatt-hour of electricity in one hour. In the summer, the air conditioner is hail, and after it stabilizes between 16 degrees and 18 degrees, don't adjust it again, and then try to turn the air conditioner into sleep mode when we sleep.

One Gree inverter air conditioner can be used for about an hour. Don't always press the switch in daily use, don't always change the mode, etc.

The energy efficiency ratio of inverter air conditioners is very high, and the so-called seasonal energy efficiency ratio is actually inconsistent with the energy consumption ratio method of Yubend fixed-frequency air conditioners.

For example, I set the room temperature at 25 degrees with virtual circles, and the inverter air conditioner is always 25, so the air dissipation in the test room has always been 25 standards; However, the fixed-frequency air conditioner may reduce the room temperature to 20, which leads to the loss of cold air in the fixed-frequency air conditioner room, which wastes cooling capacity.

The energy efficiency ratio is calculated based on cooling capacity and energy consumption alone, and the difference will not be large.

Under the same set room temperature, the inverter air conditioner reduces the heat loss in the room, which can indeed achieve the purpose of saving electricity.

However, it is at least necessary to let the air conditioner run for more than 2 hours before the energy saving starts to start saving energy (energy saving starts when the predetermined temperature is reached), and it is obvious after more than 10 hours.

Generally, when you go to buy an air conditioner, the salesman will ask you to buy a frequency conversion or a fixed frequency, generally often turn on the air conditioner, and those who want to save power for the air conditioner will choose frequency conversion, but the frequency conversion needs to be opened for a long time to save power than the fixed frequency, and a lot of money is spent to buy the frequency conversion, in fact, it is the same as the fixed frequency effect. So, how much electricity can an inverter air conditioner save in a summer? Let's take a look!

An hour doesn't save much electricity.

It is difficult to accurately calculate the difference in electricity bills, and in the same environment, 12 hours of use must be an inverter air conditioner to save electricity. The fixed-frequency air conditioner works at the rated speed during refrigeration, and the power is generally about 1000 watts, while the inverter air conditioner maintains the temperature at a low speed after the temperature reaches the set temperature, and the working range of the power front rate is between 100-1000 watts.

The longer you use it, the more electricity you save, because when the inverter air conditioner is running, if the temperature in the lab reaches our predetermined temperature, it will automatically switch to a low-speed operation, i.e. standby. Conventional fixed-frequency air conditioners are operated by turning the machine on and off, so the power consumption will be listed. Therefore, there is no clear indication of how much power can be saved by an inverter air conditioner.

Just tell us from the side that if the usage rate of air conditioning in our home is relatively high, then it is absolutely correct to choose inverter. If the utilization rate of the air conditioner is low and it cannot be turned on several times a year, a fixed-frequency air conditioner can be used.

The simplest understanding of inverter air conditioning is similar to the motor of an electric bicycle, the speed is controllable, and you can think fast or slow. Ordinary air conditioners are at a speed, and the temperature is controlled by starting and stopping, and the temperature is high when it is turned on, and when the temperature is low, it is turned off. After the temperature reaches expectations, the inverter air conditioner can reduce the motor speed and reduce the power, making the temperature more stable and the environment more comfortable.

However, it seems to have nothing to do with power saving, I don't know why manufacturers want to promote power saving, not much saving!
