What is the difference between inverter and constant frequency of air conditioner

Air conditioning is a must-have appliance for every home, and there is happiness with air conditioning in the hot summer. Usually, whether it is at home or in the office, the air conditioner is turned on almost all day of the day. In fact, air conditioners are also divided into types, and the air conditioners on the market are generally divided into:

The gap between inverter air conditioner and constant frequency air conditioner is still relatively large. So, what is the difference between inverter air conditioner and inverter air conditioner?

What is the difference between inverter air conditioner and invariable frequency air conditioner The difference between inverter air conditioner and invariable frequency air conditioner.

First, the concept is different.

The meaning of frequency conversion means that the frequency is variable and adjustable. Compared with the traditional air conditioner, the generation of inverter air conditioning is due to the rapid development of power electronics technology and technology, and the frequency conversion is to change the frequency of the mains from 50Hz to 30 130Hz. The inverter air conditioner can automatically adjust the temperature according to the set temperature, which is a relatively intelligent air conditioner.

The frequency of the constant frequency air conditioner is fixed, and the compressor speed is basically maintained at a constant value, and the temperature will not be automatically controlled.

What is the difference between inverter air conditioner and invariable frequency air conditioner The difference between inverter air conditioner and invariable frequency air conditioner.

Second, the energy saving is different.

Inverter air conditioners do not start as frequently as fixed-frequency air conditioners, so they do not generate instantaneous high currents many times. The inverter air conditioner runs at the maximum frequency after starting, and when the room temperature reaches the set temperature, it will automatically switch to low frequency operation. As a result, significant energy savings can be achieved compared to in-frequency air conditioners.

Third, the comfort is different.

The constant frequency air conditioner uses the switch on and off to adjust the room temperature, and the temperature control range is 2, resulting in a large range of room temperature fluctuations, and people will feel uncomfortable and hot and cold. The inverter air conditioner switches to low-frequency work after the room temperature reaches the set temperature, and the temperature control is precise and the temperature control range is in , so that the indoor temperature remains constant, so the comfort is better than that of the inverter air conditioner.

The difference between inverter air conditioner and ordinary air conditioner.

1. Good energy-saving effect. We all know that the inverter compressor and control system used in inverter air conditioner can automatically adjust the operating state of the compressor, while keeping the room temperature in a stable range.

2. The refrigeration and heating speed is fast. After starting, the inverter air conditioner will start to run at the maximum frequency, speeding up the cooling speed and bringing the indoor temperature to the set temperature value in a short time.

3. The starting current is small. Inverter air conditioner can be started under the state of ground temperature and low voltage, and the current is small in the process of starting, which will not cause impact on the power grid and affect the normal operation of other electrical appliances.

4. Keep room temperature stable. After the inverter air conditioner is refrigerated, the compressor will run at a low frequency to accurately control the indoor temperature and maintain the indoor temperature in a stable state.

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.

Precautions for the purchase of air conditioners.

1.Consumers should choose the type of air conditioner according to the area of their own room when purchasing, generally according to the cooling capacity of the room area multiplied by 140 watts to 180 watts, and the heating capacity is the room area multiplied by 180 watts to 240 watts, to calculate the cooling capacity and heating required by the room.

2.Choose a good after-sales brand, when purchasing air conditioners, we should choose those products with strong enterprise strength, high brand degree and perfect after-sales service. Such enterprises not only have strong technical force, but also pay special attention to quality, and the quality of such products is more guaranteed.

3.The energy efficiency ratio of the air conditioner, which reflects the amount of cooling (heat) converted into a unit of input power during the operation of the air conditioner. The larger the energy efficiency ratio of the air conditioner, the more electricity will be saved when the cooling capacity is equal, and the higher the energy efficiency ratio of the air conditioner, the more electricity will be saved, so the energy efficiency ratio is also a very important part of the precautions for buying an air conditioner.

4.Inverter and fixed speed machine, inverter has no mechanical noise of compressor start and stop, and the temperature control can also be accurate to 0 5 degrees, which is very suitable for use in the bedroom.

5.According to the actual needs of the type, household air conditioners are divided into three types: window type, split wall-mounted type, and split floor type according to different installation methods or structures. Generally, the family bedroom is split wall-mounted, and the living room is split floor-to-ceiling.

The difference between inverter air conditioner and fixed frequency air conditioner is actually very basic air conditioning common sense.

How air conditioners work.

The working principle of air conditioning is heat exchange, relying on the compressor to operate, pressurize the refrigerant (refrigerant), and then pass through the heat exchanger (evaporator, condenser) of the indoor unit and the outdoor unit to exchange heat.

You know, the air conditioner doesn't carry heat all the time, it has a temperature sensor, and when it detects that the temperature has reached a preset value, it won't carry heat.

Fixed-frequency air conditioning. For fixed-frequency air conditioners, when the temperature reaches the preset value, the compressor will shut down, that is, the fan of the external unit will not rotate, and the compressor will not work, and when the indoor temperature rises and is detected by the temperature sensor, the compressor will restart and carry the heat again. This is how the fixed-frequency air conditioner works in a repetitive cycle when it is running:

Start-stop-start-stop.

Inverter air conditioning. Because of the inverter technology, the inverter air conditioner can change the power operation, and the operating frequency is no longer fixed like the fixed frequency air conditioner.

Therefore, when the inverter air conditioner is running, for example, the indoor temperature is 30, the preset temperature is 20, and then the air conditioner will start at a high frequency when it is turned on, so that the indoor temperature will be cooled quickly, with the induction of the temperature sensor, the closer the temperature is to 20, the compressor will continue to change the frequency, even if the temperature reaches 20, the compressor will not shut down, but will change the frequency according to the temperature change, and maintain the indoor temperature at 20.

The state of the inverter air conditioner when it is running is: start at a high frequency - reduce the frequency - adjust the frequency according to the room temperature.

If the indoor temperature rises too fast, the compressor frequency will increase, and if the temperature rises slowly, the compressor frequency will slow down, and it will not stop anyway.

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

Because the operating state is different, they are also very different:

1.Temperature control.

The temperature control of inverter air conditioners is accurate, and the temperature control of fixed-frequency air conditioners is relatively poor.

2.Comfort.

Because of the poor temperature control, the fixed frequency gives people the feeling that it is hot and cold, and the inverter air conditioner gives us a higher comfort experience.

3.Energy savings.

The operating frequency of the inverter air conditioner can be changed, and the energy saving is saved in the low-frequency state, while the fixed-frequency air conditioner is often started and stopped, and the power consumption is higher.

4.Mute effect.

The noise generated by the fixed-frequency air conditioner when it starts and stops is greater, and the inverter air conditioner is relatively quieter.

5.Cost. The frequency conversion technology is high, the failure rate and maintenance cost are naturally higher, and the first frequency is more expensive than the fixed frequency.

There may be many differences between these two types of air conditioners in the advertised description. In fact, the biggest difference is that the inverter air conditioner saves electricity.

Summary. Hello, inverter means that the frequency of the compressor of the air conditioner can be changed, and it can be adjusted according to the temperature; 2.Whereas, constant frequency means that the frequency at which the compressor runs is fixed.

3.Inverter air conditioner is more comfortable, but relatively speaking, the inverter is higher, and the inverter is lower in maintenance costs.

Hello, frequency conversion means that the frequency of the compressor of the air conditioner can be changed, and it can be adjusted according to the temperature; 2.Whereas, constant frequency means that the frequency at which the compressor runs is fixed. 3.

Inverter air conditioner has stronger comfort, but relatively speaking, the constant frequency is higher, and the price of the variable frequency is relatively low.

1. The difference between comfort and fixed-frequency air conditioning: it uses a fixed frequency to adjust the indoor temperature and tolerance, and the room temperature fluctuates greatly.

2.Inverter air conditioner seepage digging tung: it is at the beginning of the operation at a high speed, and when the temperature of the room reaches the temperature we set, it will work at a low frequency, the temperature control is more accurate, and the temperature is kept more scattered and stable, the comfort is better, and it is more suitable for the elderly and children to sleep than Congtan.

2. The difference between energy-saving inverter air conditioner is not like a fixed-frequency air conditioner, which is not like a fixed-frequency air conditioner, which does not start quickly, and will not produce many times of instantaneous high current, and the inverter air conditioner runs at a high speed at the beginning, and when the temperature of the room reaches the temperature we set, it will work at a low frequency, and the energy saving effect is relatively high.

3. The difference between frequency conversion refrigeration and heating capacity. The higher the frequency of the compression section of the inverter air conditioner, the faster the speed, and the better the refrigeration effect, the greater the natural indoor temperature change, and the cooling or heating speed is 1 to 2 times that of the invariant air conditioner.

Pro, the above points are the difference between air conditioning inverter and constant frequency, Xiangli lead for the same which to change the good frequency of air conditioning, inverter air conditioning is more comfortable and energy-saving, and with our country's updated energy efficiency standards for air conditioning, traditional air conditioning will be eliminated in the next one to two years. DC inverter air conditioners will occupy the mainstream market.

The difference between inverter and constant frequency of air conditioner: different energy saving, different definitions, and different temperature control.

1. Energy saving is different.

The inverter air conditioner is equipped with an inverter, which can adjust the speed of the compressor at any time and use energy reasonably. Moreover, the compressor will not be turned on frequently, and the energy saving is more than 30%, and the speed of the fixed-frequency air conditioning compressor is output at the same frequency, which cannot effectively save energy.

2. The definitions are different.

The inverter air conditioner host is stepless variable speed, strong adaptability to voltage, can operate under the voltage of 150 volts -240 volts, can operate continuously to ensure the stability of the indoor temperature, fixed frequency air conditioning, the space provides temperature change of the unit, working under the condition of voltage of 220 volts and 50 Hz.

3. The temperature control is different.

Inverter air conditioner, the compressor power can be changed independently, maintaining a stable temperature, and the room temperature is close to the set temperature. The fixed-frequency air conditioning compressor works at a fixed frequency, with frequent start and stop, and the room temperature fluctuates greatly.

Air conditioning refrigeration principle:

Liquid vaporization refrigeration is the use of liquid vaporization of heat absorption, condensation of the exothermic effect to actually touch the mu of refrigeration, liquid vaporization to form steam, when the liquid (refrigeration fluid) in a closed container, in addition to the liquid and the liquid itself produced by the vapor of the horseman, there is no other gas.

The liquid and steam will reach equilibrium at a certain pressure, the gas at this time is called saturated steam, the pressure is called saturation pressure, and the temperature is called saturation temperature, the liquid is no longer vaporized when equilibrium, at this time, if a part of the vapor is withdrawn from the container, the liquid must continue to vaporize to produce a part of the vapor to maintain this equilibrium, and the liquid should absorb heat when vaporizing, and this heat is called the latent heat of vaporization.

The latent heat of vaporization comes from the cooled object, which makes the cooled object cold, in order to make this process continuous, it is necessary to continuously extract the steam from the container, and let it condense into a liquid and then return to the container, if the steam extracted from the container is directly condensed into a liquid, the temperature of the required cooling medium is lower than the evaporation temperature of the liquid.

The refrigeration working fluid will evaporate at low temperature and low pressure to produce a cooling effect, and condense at room temperature and high pressure, releasing heat to the surrounding environment or cooling medium, and the steam will become a high-pressure liquid after condensation at room temperature and high pressure, and its pressure needs to be reduced to evaporation pressure before it can enter the container.

The liquid vaporization refrigeration cycle is composed of four processes: working fluid vaporization, steam pressurization, high-pressure steam condensation, and high-pressure liquid depressurization.

Inverter means that the frequency of the compressor of the air conditioner is OK, and it can be adjusted according to the temperature; Whereas, constant frequency means that the frequency at which the compressor runs is fixed. The difference between inverter and constant frequency of air conditioner is as follows:

1. The difference in comfort.

Fixed-frequency air rolling: It uses a fixed frequency to adjust the indoor temperature, and the room temperature fluctuates greatly, and people will feel uncomfortable and are prone to air conditioning disease.

Inverter air conditioner: it is at the beginning of the operation at a high speed, and when the temperature of the room reaches the temperature we set, it will work at a low frequency, the temperature control is more accurate, and the temperature remains relatively stable, the comfort is better, and it is more suitable for the elderly and children to sleep.

2. The difference in energy saving.

Inverter air conditioner it is not like fixed frequency air conditioning, keep starting, will not produce many times of instantaneous high current, inverter air conditioning at the beginning of the high speed of operation, and so on the temperature of the room to reach the temperature we set, it will work at a low frequency, energy efficiency is relatively high, energy saving effect is good.

3. The difference between frequency conversion refrigeration and heating capacity.

The higher the frequency of the inverter air conditioner compressor, the faster the speed, and the better its refrigeration effect, the greater the natural indoor temperature change, and the cooling or heating rate is 1 to 2 times that of the inverter air conditioner.

Introduction to inverter air conditioners

Inverter air conditioner is to add a special inverter compressor for inverter air conditioner and inverter bureau backup control system on the basis of ordinary air conditioning, so it is called inverter air conditioner. In fact, the refrigeration principle of inverter air conditioner and ordinary air conditioner is the same, in inverter air conditioner, its host is automatically continuously variable speed.

The main engine can automatically realize the control of the cooling capacity provided by the air conditioner according to the temperature change in the room, and ensure the indoor temperature evenly when the temperature reaches the setting, so that the compressor can maintain constant operation and reduce the loss of electric energy. The inverter of inverter air conditioner adopts advanced compressor technology.

This technology allows the compressor to keep the current of the starting voltage relatively small at the time of start-up, so that the air conditioner can be started at low voltage and low temperature. Inverter air conditioner for some low temperature, unstable voltage in the area makes it difficult to start the situation has been greatly improved, inverter air conditioner stepless speed technology, so that the air conditioner is more able to adapt to the needs of cooling and heating in a larger space.
