The difference between inverter and steady, inverter air conditioner and fixed frequency air conditi

1. Inverter refrigerant R410A, environmentally friendly, but flammable and explosive; Fixed-frequency refrigerant R22 is not environmentally friendly and has a low ignition point.

2. The power consumption of inverter is calculated according to 1136 hours of refrigeration in the whole year, if you refrigate for 4 months a year, the average continuous hours per day can reach the power consumption on the energy efficiency label. That is to say, inverter air conditioners are suitable for users who use continuously for a long time, and intermittent use cannot achieve the effect of power saving; The power consumption of a fixed-speed air conditioner is calculated based on one hour of continuous non-shutdown, and the power consumption on the energy efficiency label is its maximum power consumption for one hour.

3. When the inverter air conditioner reaches the temperature, the external unit does not stop, and the compressor stops after the fixed-speed air conditioner reaches the temperature.

4. Inverter air conditioner is suitable for the use of unstable voltage, and fixed-speed air conditioner needs stable voltage.

5. There are more inverter air conditioning parts, it is not easy to repair if it is broken, the maintenance cost is relatively high, and there are more fake inverters on the market now, it is recommended to buy a fixed speed (inverter air conditioning technology is imported from abroad, and the technology is not very stable).

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.

The inverter will maintain a constant temperature, and adjust the power to generate or cool down with the level of room temperature, saving power. When you set a temperature, it is equivalent to setting a power, which consumes electricity.

Inverter air conditioning is good. The principle of use of the two air conditioners is different, the fixed frequency is when a certain temperature is set, the air conditioner will inhibit the work in this rhythm, whether we are cold or hot now, we need to manually adjust the temperature to achieve comfort at all times.

Unlike fixed-frequency air conditioners, inverter air conditioners can monitor the indoor temperature and automatically adjust the temperature to stay comfortable at all times.

How it works. Inverter air conditioners are equipped with inverters, the domestic voltage of 220V, the frequency of 50Hz of the current through the rectification filter to get about 310V of direct current, the direct current after inverter, you can get the inverter power supply used to control the operation of the compressor, which can convert the 50 Hz grid frequency into 30-130 Hz, the inverter air conditioner is a kind of air conditioner that uses inverter compressor and fuzzy control technology, can adjust the refrigeration speed according to the change of indoor air temperature. In a 15-square-meter room, the inverter air conditioner is 6 to 10 minutes faster than the fixed-frequency temperature control.

1. The comfort is different

Fixed-frequency air conditioners are switched on and off to adjust the room temperature, so the temperature varies greatly and the comfort is not strong. The inverter air conditioner runs quickly when it starts, and when the room temperature reaches a predetermined temperature, it will switch to low-frequency operation, with little temperature change and high comfort.

2. The energy saving situation is different

When the fixed-frequency air conditioner is switched on, it will form an instantaneous large current, resulting in the consumption of current. The inverter air conditioner does not need to be turned on frequently, and will switch to a low-frequency working rotation after reaching the set temperature, so it consumes less power and is more energy-saving.

I believe that anyone who has used air conditioners knows that the noise of fixed-frequency air conditioners is often much lower than that of inverter air conditioners.

Question: Is it better to invert or keep the frequency of the household air conditioner?

It must be a good inverter.

For example, if the indoor temperature reaches the set goal, the wind speed will be automatically reduced, which will also save electricity.

Hello! When the inverter air conditioner reaches the set temperature, it will not stop and will keep running at a low frequency to maintain the temperature in the room. The fixed-frequency air conditioner stops running and works when the temperature rises! Fixed-speed air conditioning

The start-up current of the fixed-speed air conditioner is several times that of the rated current, and the fixed-speed air conditioner frequently starts and stops during operation

The fixed-speed air conditioner has been heating at rated high power during operation, and the air conditioner stops after the room temperature rises to the set temperature of the air conditioner plus 1 degree. After the air conditioner is shut down, when the room temperature drops to the set temperature of the air conditioner minus 1 degree, the air conditioner starts again, and so on. The same goes for refrigeration.

The heating capacity of the fixed-speed air conditioner in winter is insufficient, with an electrically assisted heating element, and the energy efficiency ratio is only 1. The electric auxiliary heating power of the fixed-speed air conditioner is 1 2kw2Inverter air conditioning

The start-up of the inverter air conditioner is soft start, and there is no inrush current.

When the room temperature reaches the set temperature of the air conditioner, the air conditioner becomes a low-frequency operation and does not stop (setting experience and skills are required). The power consumption of continuous low-frequency operation is only one-third or even only a quarter of the rated power. The same goes for refrigeration.

Inverter air conditioners do not have electrically assisted heating elements, which are very expensive to use.

The ability of the air conditioner to regulate the indoor air temperature with the same number of horses, the inverter air conditioner is greater than the fixed speed air conditioner. Inverter air conditioners are cost-effective. The fixed-speed air conditioner starts and stops, and the room temperature fluctuates up and down, which brings discomfort to people.

The inverter air conditioner works continuously without stopping, and the indoor temperature is constant, and there is no discomfort of hot and cold. The comfort of inverter air conditioning is high.

1. The production technology is different

The technical difference is whether the frequency of the compressor is adjustable, the inverter air conditioner adjusts the speed by adjusting the frequency of the compressor motor, and the compressor of the fixed frequency air conditioner works at 50Hz.

2. Different:

Inverter air conditioner technology is advanced, so it is a little more expensive than fixed-frequency air conditioner, but inverter air conditioner is more energy-efficient because it can automatically adjust the speed.

3. The refrigeration speed is different

Inverter air conditioners refrigerate faster and can more than double the frequency when they are first turned on, while fixed-frequency air conditioners are less efficient at a fixed frequency.

The difference between fixed frequency and frequency conversion of air conditioners: different uses, different adjustments.

1. Different uses:

The use of fixed-frequency air conditioning is linked to the surrounding environment, when the ambient temperature is low, the fixed-frequency air conditioner will operate slowly, and vice versa. Inverter air conditioners can adjust the speed according to the surrounding environment, which is a little better than fixed frequency, but now inverter cannot replace fixed frequency air conditioners.

2. Adjust differently:

The compressor of the inverter product can be moderately adjusted in the case of long-term operation. When there is no need for a large amount of heat and cold, the inverter air conditioner will run at a low frequency and can maintain a constant temperature. Fixed-frequency air conditioners need to be turned on and off under artificial conditions.

How it works. Air conditioners are divided into single cooling air conditioners and cold and warm air conditioners, the working principle is the same, and the refrigerant generally used in air conditioners is freon. The characteristic of Freon is that when it changes from a gaseous state to a liquid state, a large amount of heat is released.

When the liquid state changes from a gaseous state, it absorbs a large amount of heat. Air conditioners are designed based on this principle.

The compressor compresses the gaseous refrigerant into a liquid refrigerant at high temperature and high pressure, and then sends it to the condenser (outdoor unit) to dissipate heat and become a liquid refrigerant at room temperature and high pressure, so the outdoor unit blows hot air.

1. Inverter air conditioner has good comfort.

The comfort is reflected in the three points of high stability at room temperature, fast refrigeration and heating speed, and strong low-temperature heating capacity.

2. The stability of the room temperature of the inverter air conditioner is high.

Fixed-speed air conditioner uses the start and stop to adjust the room temperature, the temperature control range is 2, and the room temperature fluctuation range is large, people will feel uncomfortable and easy to get "air conditioning disease". Inverter (variable speed) air conditioner runs at high speed at the beginning, and when the room temperature reaches the set temperature, it turns to low-frequency work, the temperature control is accurate, and the temperature control range is in, because the room temperature is stable, people feel comfortable. It is especially suitable for the elderly and children to use while sleeping.

3. The refrigeration and heating speed of inverter air conditioner is fast.

Inverter (variable speed) air conditioner runs at the maximum frequency after starting, the frequency can reach more than 130Hz, and the refrigeration and heating capacity is 2 3 times that of the fixed speed machine (50Hz), so that the cooling or heating rate of the room is 1 2 times faster than that of the fixed speed air conditioner. It allows people to quickly obtain a comfortable temperature environment.

4. Inverter air conditioner has strong low-temperature heating capacity.

In winter, if the ambient temperature is very low, the heating capacity of the air conditioner will be greatly reduced because the air conditioner will defrost frequently. On the one hand, the inverter (variable speed) air conditioner can enhance the heating capacity by increasing the frequency during the non-defrosting period, and on the other hand, during the defrosting period, the high-frequency operation defrost is adopted, so that the defrosting time is greatly reduced, and the room temperature change during defrosting is reduced from about 6 to about 2 of the fixed speed machine. As a result, comfort is greatly improved.

5. Inverter air conditioner has good energy saving.

Inverter (variable speed) air conditioners run at the maximum frequency after starting, and when the room temperature reaches the set temperature, they switch to low frequency operation, because the energy efficiency ratio is high when operating at low frequencies, and compared with fixed speed machines, it can achieve significant energy savings. According to the comparative test data of a DC inverter (variable speed) machine with a cooling capacity of 2800W and a fixed speed machine of the same capacity.

At 8 minutes, the cumulative power consumption of the inverter (variable) machine is twice that of the fixed speed machine; In about 40 minutes, the cumulative power consumption of the inverter (variable) machine and the fixed speed machine is the same; At 180 minutes (3 hours), the cumulative power consumption of the inverter (variable) machine is only that of the fixed speed machine. That is, in 3 hours, the cumulative power consumption of the inverter (variable) machine is less than that of the fixed speed machine.

When buying an air conditioner, what is the difference between choosing inverter or fixed frequency? It's never too late to understand and then buy.

Same as the same air conditioner, Gree's, turn it on to 16 degrees, the temperature of its air outlet is measured to be 9 degrees, and then Xiaomi's air outlet is opened to 16 degrees, and the air outlet is measured at 15 degrees, why is there such a big difference?

At the beginning of the fixed-frequency air conditioner, the effect will be more obvious, but it will stop working soon after reaching the set temperature, and then start to work to adjust the temperature after the temperature is restored.

Fixed frequency and inverter air conditioners have their own advantages and disadvantages, the biggest advantage of inverter is that the temperature is relatively stable, more comfortable than fixed frequency air conditioners. The fixed frequency machine is relatively simple, the failure rate is lower, and the price is relatively low, but the compressor will stop after the refrigeration reaches the set temperature, and then start the refrigeration after the temperature rises, so that it will be hot and cold, but it will not be felt if it is not a direct blow. If the conditions are good, you can buy an inverter, if you don't want to spend more money, you can buy a fixed frequency As for the energy efficiency level and how much power consumption is not the main consideration, these are all hype, the actual difference is not big, as long as the temperature is set reasonably, the difference in power consumption is not very much.

Inverter, of course.

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"Non-stop operation"to ensure the stability of the ambient temperature.

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. Since the power supply frequency cannot be changed, the compressor speed of the traditional fixed-frequency air conditioner is basically unchanged and depends on it continuously"On, stop"The compressor adjusts the room temperature, which is easy to cause the room temperature to fluctuate between one turn on and one off, and consumes more electricity.

Features of inverter air conditioner:

Energy conservation. Because the inverter air conditioner is equipped with an inverter, the operating speed of the compressor, the heart of the air conditioner, can be adjusted at any time, so as to achieve reasonable use of energy; Because the compressor will not be turned on frequently, the compressor will maintain a stable working state, which can make the air conditioner as a whole achieve the effect of saving more than 30%. At the same time, it has a fairly obvious effect on the reduction of noise and the extension of the service life of the air conditioner.

High temperature control accuracy. It can control the amount of cooling (heat) of the air conditioner by changing the speed of the compressor. Its refrigeration (heat) capacity has a change range, such as 36GW frequency conversion of the cooling capacity of 360 400W, the lead 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.

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.

Keep room temperature constant. The inverter air conditioner uses an inverter compressor, which can automatically adjust the operating frequency of the compressor according to the change of the cold (hot) load in the room. After reaching the set temperature, the inverter air conditioner runs at a lower frequency, avoiding the discomfort caused by drastic changes in room temperature.

When the load hour and the operating frequency is low, the power consumed by the compressor is small, and at the same time, frequent start-up and stop are avoided, and the stimulation is good so as to save more power.
