The weather has gradually become hotter. Many families have plans to purchase air conditioners. To buy air conditioners, many people will entangle what kind of air conditioners they are buying. Now the basic air conditioners on the market are fixed-frequency air conditioners and inverter air conditioners. In the end to buy a good conversion or fixed frequency is good? 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 conditioning is that the principle of the product in the compressor is different.
The simplest understanding: Fixed frequency, when the compressor reaches the temperature you set, it will stop, so as to get the power saving effect. When the temperature changes, the compressor will turn again.
Inverter, when the compressor reaches the temperature you set, it will maintain a uniform rotation, always maintain your set temperature can also be said to be a constant temperature rotation. The temperature difference can be ignored, relatively fixed than the fixed frequency is not easy to cause a cold, comfort is better.
Inverter air conditioner really save power?
In fact, according to the actual situation to be determined, one day to open the air conditioning more than 10 hours, please buy inverter air conditioner. Less than ten hours, please install fixed-frequency air-conditioning is enough. Only a few hours a day, then frequency and fixed-frequency air-conditioning The electricity consumption is the same.
We use inverter air conditioners in our homes. Only when it is turned on for a long period of time up to six hours, and it continues to go on, inverter air conditioners will save about 30% more power than fixed-frequency air conditioners. However, our average family cannot reach this standard. , Few people will turn on the air conditioner for a long time at home. Therefore, inverter air conditioners are not as economical as they say.
In 30 years, the maintenance master said that his family bought fixed frequency. Why?
The main advantage of inverter air conditioner is that it can steplessly adjust the speed, the temperature control is more accurate, the temperature difference is small, and the human body feels better. However, the inverter air conditioner is too expensive, which is almost 3-4 times of the fixed frequency. If the price is the same, the frequency conversion is good. The problem is that inverter air conditioners are twice as expensive as fixed-frequency air conditioners. When you use an air conditioner for ten years, you are willing to take out the power-saving ten-year money first. Then you can buy inverters!
The most critical thing is that the fixed frequency is still a good repair, even if it is completely broken. Compressor connected to 220v also have to give me turn. Inverter What ... ... ... that a set of driver board did not come under a few hundred, ah, hey.
The final conclusion:
Both the fixed frequency and the frequency conversion have their own advantages and disadvantages. Therefore, I suggest that if the family economic conditions are normal, they will still use fixed-frequency air-conditioning, and they will also be cheaper in terms of the price. The fixed-frequency air-conditioning structure is relatively simple. Therefore, the probability of failure is relatively low, and maintenance costs are also relatively cheap. In any case, it is more practical to use fixed frequency.
