Is fixed frequency air conditioner as good as inverter?

There are many kinds of frequency converters, due to the unstable voltage, the air conditioner used to have a rectifier part, let it work at a fixed frequency, remove this part, save costs, and it becomes a frequency conversion. This also includes all equipment with motors, such as washing machines.

At this stage, the international frequency conversion refers to DC frequency conversion, which means that the equipment is not used with 220 volt electricity, but the voltage conversion rectification into direct current, that is, the alternating current with a frequency of 50 hertz into direct current without frequency, this process is called frequency conversion.

The purpose of this is to save energy, reduce noise and improve efficiency.

However, the failure rate will increase, mainly because there are more rectifier circuits and DC motors, which will accumulate carbon.

The country's technology is immature, and there are sometimes deceptive behaviors of consumers, stealing concepts, and so on.

If you buy an imported original machine, you can consider frequency conversion, and the domestic machine is still with high fixed frequency power.

The more marked energy-saving machines the worse the effect, the energy is conserved, it is impossible to achieve the desired effect with only one kilowatt-hour of electricity, don't listen to advertisements.

Inverter air conditioner is power-saving and efficient!

Fixed frequency is more power-saving in a short period of time, frequency conversion is more power-saving for long-term use, and the life of the inverter motor is also relatively long, so frequency conversion is recommended.

The frequency conversion is good, ** is also a little higher, and the air at home is also fresh.

Of course, it is good for frequency conversion. It can save electricity, and the noise is much smaller.

The beautiful ones should be a little better.

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.

This needs to be based on your own family situation, if the family's economic conditions are average, or use fixed-frequency air conditioning, and the fixed-frequency air conditioner is cheaper in price. If you turn on the air conditioner for less than an hour, buy a fixed frequency, ** cheap; On the contrary, buy an inverter air conditioner, which is more energy-saving.

The biggest difference between inverter and fixed-frequency air conditioner is that the product is used in the compressor.

Fixed-frequency air conditioner is when a certain temperature is set, the air conditioner will inhibit the work in this rhythm, no matter 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.

1. The difference between fixed frequency and frequency conversion.

In terms of working principle, the main difference between fixed frequency and variable frequency is the way the compressor works.

Fixed-frequency air conditioning, when the indoor temperature reaches a predetermined temperature, the compressor stops running; Inverter air conditioners, on the other hand, keep them running at low frequencies.

2. Which is better, fixed-frequency air conditioner or inverter air conditioner?

Let's compare the ** and comfort of fixed-frequency air conditioners and inverter air conditioners.

1、**。The cost of the new inverter technology used in inverter air conditioning is more expensive than that of fixed-frequency air conditioners, so inverter air conditioners are relatively more expensive than fixed-frequency air conditioners.

2. Indoor temperature difference.

Since the compressor stops working after the fixed-frequency air conditioner reaches the indoor temperature, the indoor temperature will change to a certain extent during the period when the compressor is stopped, which will eventually lead to a large indoor temperature difference;

After the inverter air conditioner reaches the indoor temperature, the compressor enters the low-frequency operation state, so that the indoor temperature will not change too much.

3. The number of Shu silver is moderate.

Through the comparison of the indoor temperature difference in point 2, the inverter air conditioner can better control the indoor temperature and will not let the indoor temperature change too much, so the comfort is also better.

The elderly and children in the family are sensitive to temperature changes, and if the temperature changes too much, there is a risk of catching a cold. Therefore, if there are elderly people and children at home, it is recommended to buy inverter air conditioners.

4. Maintenance and maintenance costs.

Although inverter air conditioners have better technology, inverter air conditioners are also more likely to break, with higher maintenance frequency and higher maintenance costs.

3. Is the inverter air conditioner really power-saving?

There are many people who think that inverter air conditioners are more energy-efficient, but in fact, this power saving is relative. A friend who sells air conditioners said that inverter air conditioners work continuously for more than 6 hours to reflect their power-saving significance.

However, for many ordinary families, it is not very common for the air conditioner to be turned on for more than 6 hours in a row, so the significance of inverter air conditioning to save electricity is not particularly great.

1. If there are elderly and children at home, it is better to buy inverter air conditioners;

2. Ordinary families are recommended to buy fixed-frequency air conditioners, which are not easy to break, and are cheaper;

3. Families who often turn on the air conditioner for a long time are recommended to buy inverter air conditioners.
