Is an inverter air conditioner really that power efficient? Only 1 kilowatt hour of electricity a ni

Hehe, people with a bit of brains and scientific knowledge understand that "as long as 1 kilowatt-hour of electricity a night" is impossible to drop; No matter what air conditioner, if you set it to a ventilated state (no refrigeration, only blowing), you can't use 1 kilowatt-hour of electricity a night; Also, how long is "one night"? According to my experience of using inverter air conditioning, in addition to the comfort (will not be cool and hot) better than fixed-frequency air conditioning, there is no advantage, and even more power-intensive, and the failure rate is extremely high

My family bought two Mitsubishi Electric air conditioners, and one of them had problems with the inverter. The others are not inverters, and they have always been used well.

I watched a program on CCTV that introduced inverter air conditioners. The inverter air conditioner is turned on for one hour --- 2 hours, and the electricity consumption is twice that of the fixed-frequency air conditioner, the longer the time it is on, for example, your home is more luxurious, 24 hours a day, in addition to ventilation for 2 hours, the air conditioner has been turned on. Then choose the right inverter air conditioner.

If your house is like my parents, knocking on the door and timing it for an hour, then there is no need to choose an inverter air conditioner. Considering the cost of electricity**, **poor and possible maintenance costs, it is recommended that you still use a Gree fixed-frequency air conditioner. Considering energy saving, emission reduction, and green environmental protection, it is recommended that you buy a fan directly without installing an air conditioner.

When using the air conditioner for a long time, the inverter air conditioner does have an advantage, if you drive it for three or four hours a day, it is still cost-effective to set the frequency, and the frequency conversion'Expensive. I just got three hang-up machines and one cabinet machine, all of which are fixed-frequency. Inverters are much more expensive.

There is basically not much difference in power consumption. Frequency conversion will save a little bit of the world, but don't expect a difference of a few kilowatt-hours of electricity, just one or two degrees. The focus is on the temperature of the inverter is more stable and more comfortable.

There are slight differences in air conditioners of different brands and models. Taking 1 HP air conditioner as an example, 1Hz reaches a constant temperature state for 24 hours, but the power consumption in the first two hours of shutdown is large, reaching more than 2 degrees, so it must consume 3-4 degrees of electricity when the inverter air conditioner is turned on for 8 hours a night.

The power consumption and maximum power of the inverter air conditioner are closed, and the greater the power of the air conditioner, the more power will be consumed. In addition, it is also related to the size of the room, whether the room is blocked from the sun, and the thermal insulation effect of the house. All in all, there are many constraints that must be considered comprehensively.

The actual difference is not very large, when the external ambient temperature is very high, the difference is about one kilowatt-hour; When the external ambient temperature is not high, the phase difference temperature will be slightly higher. The main reason is that the noise of inverter air conditioning is small, and the comfort is better than that of fixed frequency.

There is basically not much difference in power consumption. Inverter will save a little, but don't expect a difference of a few kilowatt-hours. The focus is on the temperature of the inverter is more stable and more comfortable.

This one will still be 1 to 2 degrees off.

If it takes a long time, then it will be more advantageous and the power saving effect will be better.

Nowadays, many people prefer to use inverter air conditioners, because inverter air conditioners are relatively more energy-saving, and in the process of using inverter air conditioners before judgment, they are also more worried about the problem of how many kilowatt-hours of electricity in a night of inverter air conditioners, and the difference between inverter air conditioners and fixed frequency should also be mastered, so that they can have more understanding. Now many people prefer to use inverter air conditioners, because inverter air conditioners are relatively more energy-saving, for inverter air conditioners are still in the process of use, they are also more worried about the problem of how many kilowatt-hours of inverter air conditioners are used overnight, and the difference between inverter air conditioning and fixed frequency should also be mastered, so as to have more understanding.

How many kilowatt-hours of electricity does an inverter air conditioner have at night?

The inverter air conditioner is relatively energy-saving, it is a soft start when it is turned on, and the current will not be wasted without impact. During operation, the inverter air conditioner will automatically change to low frequency and continue to maintain the temperature without downtime. When the temperature is maintained, it does not consume power, and it is only one-third or even one-quarter of the specified amount of power.

When the outdoor temperature reaches 35 degrees Celsius and the indoor temperature is 27 degrees Celsius, the power consumption of the ordinary air conditioner is 2 86 degrees and the power consumption of the AC inverter air conditioner is 2 85 degrees. When the outdoor temperature reaches 40 degrees Celsius and the indoor temperature is 32 degrees Celsius, the power consumption of ordinary air conditioners is 4 25 degrees, and the power consumption of AC inverter air conditioners is 3 97 degrees.

What is the difference between air conditioner inverter and fixed frequency?

a. The working principle of DC inverter air conditioner is to convert the 50Hz power frequency AC power supply into DC power supply, and send it to the main circuit of the power module, the power module is also controlled by the microcomputer, the difference is that the module outputs a DC power supply with variable voltage, and the compressor uses a DC motor, so the DC inverter air conditioner can also be called a full DC variable speed air conditioner. DC inverter air conditioners do not have an inverter link, which is more energy-efficient than AC inverter in this regard.

b. The working principle of AC inverter air conditioner is: inverter technology is a technology that changes the frequency of the power supply through the inverter, thereby changing the speed of the compressor (see Figure 1 Block diagram of inverter inverter inverter). The AC to DC conversion is carried out through the inverter first, and then the DC to AC conversion is carried out through the inverter, so as to control the speed of the AC motor.

The control of the inverter is to transmit the indoor temperature information to the microcomputer through the sensor, and output a waveform with a certain frequency change to control the frequency of the inverter. When the indoor air conditioning is rapidly cooled or heated rapidly, the indoor air conditioning load increases, the compressor speed increases, and the refrigeration capacity increases proportionally, on the contrary, when the indoor air conditioning load decreases, the compressor runs normally or decelerates.

Inverter air conditioner a few degrees of electricity a night, after reading the above introduction, people should already know it, in fact, as long as it is purchased, it can achieve good quality assurance when it is used, so that people can use it more assured, the difference between air conditioning frequency conversion and fixed frequency is also very large, only after mastering it can we do it, and no matter what, we should go to the regular store to buy.

The power consumption of the inverter air conditioner when it is just turned on is larger than that of the ordinary fixed-frequency air conditioner, and only after 5 hours of start-up, can the power-saving advantages of the inverter air conditioner be reflected.

Inverter air conditioner is under the control of inverter module, the speed of the compressor can be fast or slow, so the cooling capacity or heating capacity of the air conditioner can also be large or small, fast or slow, when the air conditioner is just turned on, the inverter air conditioning compressor is in a high-speed state, so the refrigeration capacity or heating capacity is very large, and the indoor temperature can quickly reach the set temperature; When the room temperature reaches the set temperature, the compressor is in a low-speed operation state, and the cooling capacity or heating capacity is very small, and the power consumption is very small, so as to maintain the indoor temperature unchanged. Therefore, the cooling or heating speed of inverter air conditioner is fast, the indoor temperature difference is small, the comfort is good, and the long-term reasonable use can give full play to its power-saving characteristics. Inverter air conditioners are especially suitable for use in bedrooms or rooms with long power on periods of time.

However, the structure of inverter air conditioners is relatively complex, so the manufacturing cost is high, and the installation must also be vacuumed, and the maintenance cost is also very high.

The compressor speed of ordinary fixed-frequency air conditioner is always the same, so the cooling capacity or heating capacity is also the same, it is to maintain the indoor temperature within a certain range by controlling the start and stop of the compressor, so the indoor temperature difference is large and the comfort is poor. However, the structure of Mengjian is relatively simple, the manufacturing cost is low, and the maintenance cost is relatively small. It is especially suitable for rooms where the boot time is not very long, or the indoor temperature difference is not high.

The reason why the inverter air conditioner saves electricity is that after the set temperature is reached, the compressor can be operated with reduced load. Although the compressor is still running, it saves a lot of power, and the control of the room temperature is relatively stable.

Ordinary air conditioners can't do this, the compressor is very cold when it is running, and the temperature in the city will quickly rise when it is shut down. The temperature is not smooth.

If the inverter air conditioner is small because the room is large, the temperature in the city will not be able to drop, and the compressor will run 100%, and the sedan will not save electricity.

Moreover, it is now in the heating state, the operating state of the air conditioner is to absorb the heat from the outside and release it to the indoor, the outside is already very cold, the refrigerant system should use a lower temperature to absorb heat from the outside, and the compressor must of course run at full load. Moreover, the indoor unit generally has an electric auxiliary heating system, which is an electric heating tube to put it bluntly. to make up for the lack of heating.

In a word, it is very, very not cost-effective to use air conditioning for heating in winter. Whether it's an inverter air conditioner or not.

It depends on the length of the start-up time, the refrigeration of the inverter air conditioner is fast, the indoor temperature difference is small, and the comfort is good, if the boot time is very long, it can give full play to its power-saving advantages, but if the start-up time is not long, it will not be able to play its power-saving characteristics, and even consume electricity more than ordinary timed air conditioners.

When the inverter air conditioner is just turned on, according to the indoor temperature difference, the compressor runs at high speed, so that the indoor temperature quickly reaches the set temperature, the power consumption at this time is very large, almost double that of the scheduled air conditioner, but when the indoor temperature reaches the set temperature, the eggplant pin compressor enters the low-speed operation to maintain the indoor temperature unchanged, at this time, the power consumption of the air conditioner is very small, and the power consumption will be very small if such a power consumption is maintained for a long time. Generally, it saves 10 40 more power than the fixed-speed air conditioner, and the longer the power on time, the more power-saving the inverter air conditioner is.

The power of a fixed-speed air conditioner is generally about 800 watts, and the power consumption when working at full load is the degree, and the average power consumption is between degrees, and the power consumption is related to the ambient temperature, the level of the indoor set temperature, the size of the room area and the sealing and thermal insulation performance. The power consumption of the inverter air conditioner is very large when it is just turned on, and only when the indoor temperature reaches the set temperature, the power consumption is reduced, and the average hourly power consumption is between degrees (if the inverter air conditioner always maintains high-speed operation, the power consumption is greater than that of the fixed-speed air conditioner).

1. Is it better to have an inverter air conditioner or a fixed frequency?

1. Power saving. The buying point of inverter air conditioner* is power saving, it can automatically simplify the indoor temperature, when the set temperature is reached or exceeded, the indoor unit and the outdoor unit will carry out low-frequency work, maintain the temperature unchanged, reduce the work efficiency to achieve the effect of power saving. The fixed-frequency air conditioner means that when the temperature reaches the preset value, the outdoor unit of the air conditioner will stop working, and when the temperature rises, the outdoor unit will be turned on again.

2、**。Because the frequency conversion function has the effect of intelligent work, it is more expensive than the fixed frequency function, and the frequency conversion air conditioner of different brands and models is generally higher than the fixed frequency air conditioner by about 500-1000 yuan.

3. Practical family.

On the topic of which air conditioner is more economical, it also needs to be analyzed on a case-by-case basis. If you have an air conditioner for less than 5 hours, you can choose a cheaper fixed-frequency air conditioner, but if you have to turn on the air conditioner every 20 hours, it will be more cost-effective to buy a power-saving inverter air conditioner.

2. Several kilowatt-hours of electricity for inverter air conditioners a night.

1. How many kilowatt-hours of electricity does a hail of inverter air conditioner have at night? Different brands and models of air conditioners vary. Taking 1 HP air conditioner as an example, 1Hz reaches a constant temperature state for 24 hours, but the power consumption in the first two hours of the machine is large, reaching more than 2 degrees, so it takes 3-4 degrees to turn on the inverter air conditioner for 8 hours a night.

2. The power consumption of the inverter air conditioner is related to the * power, the greater the power of the air conditioner, the more power consumption. In addition, it is also related to the size of the room, whether the room is blocked from the sun, and the thermal insulation effect of the house. All in all, there are many factors that affect and need to be considered comprehensively.

3. What brand of inverter air conditioner is good?
