How big is it to buy an air conditioner? Is it appropriate to convert or fix the frequency?

How big to buy an air conditioner is to choose according to your own space.

Comparison of Variable Frequency and Fixed Frequency:

Inverter air conditioner is based on ordinary air conditioner, which selects a special compressor for inverter, and adds a variable frequency control system.

A fixed-frequency air conditioner is a unit used to provide a space area (usually closed) with a treatment for changes in air temperature.

The advantages of inverter air conditioners are: more accurate temperature control, low noise, more comfortable human body feeling, and long compressor service life.

The advantage of ordinary air conditioning is that it is cheaper and the comfort of the whole room will be better when the inverter is used.

The compressor of the traditional fixed-speed air conditioner relies on its continuous "opening and stopping" to adjust the indoor temperature, which is easy to cause the room temperature to be hot and cold between opening and stopping, and consumes more electric energy.

Inverter air conditioners rely on the speed of the compressor to achieve the purpose of controlling room temperature, with small room temperature fluctuations, less power consumption, and greatly improved comfort. The inverter air conditioner using inverter control technology can automatically select the heating, cooling and dehumidification operation modes according to the ambient temperature, so that the room can quickly reach the required temperature in a short time and fluctuate with a small temperature difference under the condition of low speed and low energy consumption, so as to achieve fast, energy-saving and comfortable temperature control effect. However, the premise of variable frequency air conditioning is that the power generation time is longer each time, generally more than 5 hours, so as to give full play to its power-saving advantages.

Because when the inverter air conditioner is just turned on, the compressor is in a high-speed state, and the power consumption at this time is very large, so that the indoor temperature quickly reaches the set temperature. If the start-up time is short, the inverter air conditioner will not be able to give full play to its power-saving advantages, and even consume more electricity than ordinary fixed-speed air conditioners.

Inverter air conditioners and fixed-frequency air conditioners have their own characteristics, so you should choose according to your actual needs when purchasing.

To solve this problem, we must look at the specific use situation.

If the air conditioner usage rate is not high, and it is not to be installed in the bedroom, then it is good to choose a fixed frequency one! The power-saving advantage of inverter air conditioner should be reflected from long-term operation, if the usage rate is not particularly high, then there is little difference between fixed frequency and inverter in terms of electricity consumption.

On the other hand, because the inverter air conditioner does not start frequently, the noise during operation will be relatively smaller, but the compressor is installed outdoors in the outdoor unit, and the impact on the indoor unit depends on the specific installation location of the outdoor unit, and the impact on the indoor unit is generally not too great!

The third aspect is that the relative advantage of fixed frequency is more obvious than that of frequency conversion; So if you want to choose, you can at least refer to the three aspects I said above, and decide according to the actual usage!

Recommended:

If you install it in the living room, buy a fixed speed. Because the inverter is not used for a short time, it does not save electricity, and the living room is often used for a short time.

If you want to use it in the bedroom. Install inverter, because the bedroom is generally turned on all night. When the temperature is reached, it is maintained with very little power, which can save energy.

It is also because the inverter does not use the fixed speed machine to start and stop to maintain the temperature, but has been running stably and with low power, so that you can not feel the cool breeze when you start and the stuffy heat when you stop it, which is more comfortable.

On the whole, it is better to convert the frequency, because it will adjust the speed of the motor according to the change of ambient temperature, when the temperature rises, the motor will increase the speed to increase the cooling effect, and vice versa, reduce the speed of the motor to reduce the cooling capacity.

Before purchasing air conditioners, we must first reserve a good installation position for air conditioners, and during the decoration process, we must first lay a good wall hole, pull the wires, etc., we can reserve the location of home appliances installation through the designer's measurement room, apply for Tuba Rabbit free room measurement service, and have professional designers come to measure the room for free, and help us plan the reserved location of household appliances for free.

Inverter air conditioners and fixed-frequency air conditioners have the advantages and disadvantages of each mu chain, and the choice of which air conditioner is the best needs needs to be made according to the actual situation and needs of the individual.

Inverter air conditioners have strong cooling capacity and adjustment range, and can automatically adjust the cooling effect according to the changes in indoor and outdoor temperatures. The cooling effect of fixed-frequency air conditioners is relatively fixed.

Inverter air conditioners can automatically adjust the cooling or heating effect according to the indoor and outdoor temperatures, which can effectively reduce energy consumption. The energy-saving performance of fixed-frequency air conditioners is poor.

Due to the high frequency of use, inverter air conditioners need to be cleaned and maintained frequently. Fixed-frequency air conditioners, on the other hand, have a longer service life and lower maintenance costs.

Inverter air conditioners of the same brand and model are higher than fixed-frequency air conditioners**, but the average annual cost of use can be negotiable.

Therefore, if you need to use an air conditioner in an area where the temperature changes frequently or are easily affected by the temperature, it is recommended to choose an inverter air conditioner for better cooling effect and energy-saving performance.

If you only need to use the air conditioner at a specific time or place, and you want to reduce maintenance costs quickly and affordably, you can choose a fixed-frequency air conditioner.

Buying an air conditioner is good for inverter.

1.High temperature control accuracy.

It can control the amount of cooling (heat) of the air conditioner by changing the speed of the compressor. There is a change in the cooling (heat) capacity, such as the cooling capacity of 36GW frequency conversion is 360 400W, and the heating capacity is 300 6800W, so the indoor temperature control can be accurate to 1, so that the human body feels very comfortable.

2.The temperature is adjusted quickly.

When there is a large difference between the room temperature and the withering temperature, the inverter air conditioner will work with the maximum power as soon as it is turned on, so that the room temperature will rise or fall rapidly to the set temperature, and the refrigeration (heat) effect is obvious.

Fixed-frequency air conditioner Gree's is better. The difference between fixed-frequency air conditioner and inverter air conditioner is that inverter air conditioner is mainly power-saving, low noise, fast refrigeration, and wide use voltage; And the fixed-frequency air conditioner is a little worse than that. **The aspect is that the inverter air conditioner is more expensive, and the fixed-frequency air conditioner is cheap and easy to maintain.

The fixed-frequency air conditioner is relatively stable when the speed is working, so when the indoor stability reaches the set temperature, the compressor in the fixed-frequency air conditioner needs to be shut down to maintain the temperature, but when the inverter air conditioner is running, the speed of the operation can be adjusted according to the indoor temperature compressor, so the indoor temperature of the inverter air conditioner will be more comfortable than that of the fixed-frequency air conditioner.

Fixed frequency is at least half cheaper than the ** of frequency conversion, and the maintenance cost of frequency conversion is also more expensive than that of fixed frequency, the overall analysis of the maintenance rate of inverter air conditioning is greater than that of fixed frequency air conditioning, it is really dare not buy repair.

After the inverter air conditioner reaches the set temperature, the compressor does not stop but runs at a low speed, the indoor temperature is kept stable, the current is reduced, and the power can be saved for a long time. The fixed-frequency air conditioner will stop directly when the temperature reaches the temperature and restart when the temperature exceeds the set value. If the current fluctuates greatly, the electricity consumption will be large.

Gree is the leading brand of domestic air conditioners, and the difference between fixed frequency and inverter air conditioners is large, as follows:

1. The inverter air conditioner is high.

On the market, the common inverter air conditioner is generally between 3000 and 4000, and the fixed-frequency air conditioner is about 2000, and the price of the inverter air conditioner is usually 1000 2000 yuan more expensive than the fixed frequency! It's almost time for 2 fixed-frequency air conditioners.

2. Inverter air conditioner maintenance trouble.

The electronic control design of inverter air conditioner is more complex, and the failure rate is higher than that of fixed frequency, so the maintenance cost is also high, for example, the inverter drive of inverter air conditioner is damaged, if a drive module is replaced separately, it will cost about 600 yuan. In addition, if the compressor is replaced, the cost is much higher than that of a fixed-frequency air conditioner with the same number of horses.

Most of the refrigerants used in frequency conversion are R410A and R32, which need to be vacuumed for installation and maintenance. Because the pressure of these two refrigerants is high, if they are not pumped, it will lead to uneven operating pressure, poor refrigeration effect, and even failure problems.

The refrigerant used in the fixed-frequency compressor is R22 (Freon), which does not need to be vacuumed when installed, and only needs to be emptied. There is no need to drain the refrigerant during maintenance, and the refrigerant can be increased directly. Therefore, the high after-sales cost of inverter air conditioning installation is much higher than that of fixed-frequency air conditioner!

3. Inverter air conditioners do not save money when used for a short time.

Calculate a simple account. According to the use of 3 months, 8 hours a day, the average power of the air conditioner is 2000W. The total power consumption of fixed-frequency air conditioners is 1920 kWh, and the total power consumption of inverter air conditioners is 1510 kWh, which is relatively energy-saving 410 kWh and energy-saving electricity costs 300 yuan.

In fact, if the use time is short, both are actually running at power frequency (50Hz), and the power consumption is basically similar.

Inverter air conditioners are better and don't make much difference.

Advantages of inverter air conditioner over fixed frequency air conditioner:

More energy efficient. Inverter air conditioners determine the power according to the amount of need, so the efficiency is high. The fixed-frequency air conditioner is turned on and off, and the power consumption is very large every time.

When the fixed-frequency air conditioner is running, the host has been in a state of "high-speed rotation"; The inverter air conditioner can automatically adjust the speed according to the actual situation. More comfortable The temperature of the fixed-frequency air conditioner fluctuates greatly, with a fluctuation range of 4. The inverter air conditioner can accurately control the temperature, the temperature fluctuation is only 1, and the indoor is always in the most suitable state.

Quieter The outdoor unit of the inverter air conditioner does not need to be constantly restarted, which effectively reduces the noise caused by restarting, and the overall optimized design of the fan and air duct makes it quieter.

Inverter air conditioner has a longer life Inverter compressor has better performance and longer service life than fixed-frequency compressor. In addition, the inverter household air conditioner not only has the advantages of inverter air conditioning, but also has the characteristics of more space-saving and more beautiful air conditioning, which perfectly matches various decoration styles.

The difference between air conditioner inverter and fixed frequency.

The biggest difference between inverter and fixed-frequency air conditioner is that the product is used in the compressor. If the compressor of the inverter product can be moderately adjusted in the case of long-term operation, if the indoor does not need a lot of cold and heat, the air conditioner will run in a low-frequency state, intelligent constant temperature control, and the fixed-frequency product needs to be adjusted on and off the cold and hot of the air conditioner under artificial circumstances.

Gree air conditioner has a very high reputation at home and abroad, and Gree air conditioner is synonymous with excellent air conditioning products over the years. The difference is not very big, but the power consumption of the inverter air conditioner is relatively small, the noise is relatively small, and in terms of maintenance, the maintenance of the fixed frequency air conditioner is more convenient, and the refrigeration effect is faster.

A fixed-frequency air conditioner is a unit used to provide a space area (usually closed) with a treatment for changes in air temperature. The voltage of the national household power grid is 220 volts, 50 Hz, and the air conditioner that works under this condition is called a fixed-frequency air conditioner.

Since 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.

Inverter air conditioner is to add an inverter to the structure of conventional air conditioner. The compressor is the heart of the air conditioner, and its speed directly affects the efficiency of the air conditioner, and the inverter is the control system used to control and adjust the speed of the compressor, so that it is always in the best speed state, so as to improve the energy efficiency ratio (at least 30% more energy-saving than the conventional air conditioner).

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 conditioner unit 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.

Is it better to buy inverter or fixed frequency for air conditioners?

Or frequency conversion, the use of the frequency conversion machine outdoor unit is small, easy to move, and back home must enjoy the best effect in a short time, the efficiency of the frequency converter is much faster than the fixed frequency. Moreover, the noise of the inverter machine is low and the comfort is high, so the inverter is the first choice.

Let's decide this according to your own use! If you want to rely on air conditioning in winter and summer, it is more economical to choose frequency conversion for a long time; If you only indirectly turn on the use of an energy-efficient fixed frequency machine in summer, it would be good! Of course, DC inverter air conditioners are the first choice for families, which are energy-saving and environmentally friendly, and have lower noise!

The inverter is good, the indoor temperature is measured according to the temperature measurement sensor, and the inverter controller controls the speed of the compressor.

If the elderly buy it, they must be reluctant to use it often, so it is recommended to buy a fixed frequency, after all, the frequency conversion is relatively slightly more expensive, and the frequency conversion is relatively easy to have problems.

The effect is also good, and it is not expensive.

Household air conditioners, whether they are inverted or not, are the most expensive in the first hour The longer the air conditioner is also turned on, the more electricity is consumed, and the power saving of the inverter air conditioner is only relative to the ordinary air conditioner Once the inverter air conditioner reaches the set temperature, the power consumption is relatively uniform, and the power consumption is relatively small, and the energy consumption of the ordinary air conditioner will be relatively large, not that the inverter air conditioner will play for 5 hours and 4 hours The power saving of the inverter air conditioner is mainly in the frequency conversion period after reaching the set temperature At the beginning, the power consumption of the air conditioner is not inverter, compared with ordinary air conditioners, the longer the inverter air conditioner is on, the more power saving

Therefore, it is better to buy inverter, it can save electricity for a long time, it will not be used for a long time, and it will not waste electricity, the most important thing is that its comfort will be much higher than that of fixed frequency. Isn't buying an air conditioner just buying comfort? Recommend your beauty of the frequency conversion is very good, according to your specific requirements can go to the store to ask, the sales staff are quite enthusiastic and professional.
