The weather has gradually become hot, and many families have plans to purchase air conditioners. If you want to buy air conditioners, many people will entangle what kind of air conditioners they buy. The air conditioners on the market today are basically fixed-frequency air conditioners and inverter air conditioners. So, is the air conditioner to buy the inverter or the fixed frequency? We all come together to understand it.
The difference between air conditioning frequency conversion and fixed frequency
The biggest difference between frequency conversion and fixed frequency air conditioners is that the application principle of the products on the compressor is different.
The simplest understanding: fixed frequency, when the compressor reaches the temperature you set, it will stop, thus getting power saving effect. When the temperature changes, the compressor will rotate again.
Frequency conversion, when the compressor reaches the temperature you set, it will keep rotating at a constant speed, and the temperature that you set is maintained at a constant temperature. The temperature difference can be neglected, and the relative frequency is not easy to cause a cold, and the comfort is better.
Is the inverter air conditioner really saving electricity?
In fact, according to the actual situation, if the air-conditioning time is more than ten hours a day, please buy inverter air conditioner. For less than ten hours, please install a fixed-frequency air conditioner. When only a few hours a day, the power consumption of the inverter and fixed-frequency air conditioner is the same.
In our home, we use inverter air conditioner. Only when it is turned on for 6 hours for a long time, and continuously keep going, the inverter air conditioner will save about 30% than the fixed frequency air conditioner. However, our average family does not meet this standard, and few people will turn on the air conditioner at home for a long time. Therefore, inverter air conditioners are not as economical as the propaganda said.
30 years of maintenance master said that he bought a fixed frequency, why?
The main advantage of inverter air conditioner is that it can be stepless speed regulation, temperature control is more accurate, temperature difference is small, and human body comfort is better. But the inverter air conditioner is too expensive, almost 3-4 times of the fixed frequency. If the price is the same, it is a good frequency conversion. The problem is that the inverter air conditioner is twice as expensive as the fixed frequency air conditioner. Willing to take out the money for the ten years of power saving, then you can buy the inverter!
The most important, the fixed frequency is mainly good repair, even if it is all broken. The compressor is connected to 220v and I have to turn it. Frequency conversion?... That set of driver boards didn’t come out a few hundred pieces, oh, oh.
Final conclusion:
Whether it is fixed frequency or frequency conversion, each has its own advantages and disadvantages. Therefore, I suggest that if the family's economic conditions are normal, it is still using fixed-frequency air conditioners, and the price is also relatively cheap. Then the fixed-frequency air-conditioning structure is relatively simple, so the probability of failure is relatively low, and the maintenance cost is relatively cheap. In any case, the fixed-frequency is more practical.
