Do many people want to stay in the air conditioning room in summer? The cool environment is inseparable from the contribution of air conditioning. Summer is also the peak season of air conditioning sales. So you will choose fixed frequency or variable frequency air conditioning? What is the difference between fixed frequency air conditioning and variable frequency air conditioning?
First of all, we need to understand the difference between frequency conversion and constant frequency of air conditioning. The fundamental difference between them is that the operation principle of the compressor is different. The variable frequency air conditioning compressor can adjust the appropriate temperature when it is opened for a long time. It is an intelligent constant temperature control.
Its characteristic is very energy-saving. Its built-in frequency converter can adjust the rotation speed of the compressor to reach the ideal temperature. For example, you want to reach the temperature of 26 degrees in the room, and then the frequency converter air conditioner can help you adjust it to 26 degrees, and then it will remain at this temperature, and it will not continue to reduce the temperature. Its compressor will not be opened frequently, so the advantage is that it can not only Good energy saving, but also can reduce noise and extend the service life of air conditioning.
The second characteristic is that the temperature can be adjusted quickly. When the temperature difference between indoor and outdoor is large, the variable frequency air conditioner will work with the maximum power, so that the room temperature will rise or fall rapidly, and the temperature change will be very obvious.
The third characteristic is to be able to keep the room temperature constant. When our room temperature reaches a certain value, the variable-frequency air conditioner will stop working. When the room temperature drops or exceeds the set temperature, the variable-frequency air conditioner will start working, so that the overall temperature will maintain a good state.
The compressor of constant frequency air conditioner is always at the same speed, so its characteristic is relatively stable and can adapt to a variety of environments. Comparing the two, we will find that the disadvantage of variable frequency air conditioning is that its price is relatively expensive, the structure of components inside the air conditioning is relatively complex, and the failure rate is high. The disadvantage of constant frequency air conditioning is that it consumes a lot of power and has poor temperature control, so it will lead to a bad feeling. To sum up, both have advantages and disadvantages, but at present, frequency conversion is more popular.
This problem is considered from three aspects: comfort, price and power consumption.
First, I don't need to think about the comfort. The frequency conversion must be good. Variable frequency air conditioning realizes accurate temperature control. Many brands of variable frequency air conditioning claim that the temperature is accurately controlled to 0.1 ℃. The temperature control is accurate, and it will not be hot or cold, and the comfort is very good. Many bedrooms are used at home. Constant frequency is easy to be hot and cold, and the body feels uncomfortable. In developed countries that pursue high-quality life, 99% of air conditioners are variable frequency.
Second, the market price of frequency conversion is expensive, and the fixed frequency is much cheaper. For people who are short of money, fixed frequency air conditioning can save a lot of money.
Third, the power consumption performance should be separated. The power consumption is basically the same when the machine is started for a short time. When the machine is just started, the power consumption of frequency conversion may be greater than that of constant speed. If the air conditioner is used for a long time, such as continuous working for 12 hours or more, the power consumption of the variable frequency air conditioner will be 5% - 10%. According to the data statistics of the national recognized experiment center, the variable frequency air conditioner can save about 20% of the power consumption compared with the constant speed air conditioner.
To sum up, I personally suggest that the impact of variable frequency and fixed frequency on the unit air conditioner is not significant, and the bedroom has high requirements for comfort. It is recommended that variable frequency, especially for rooms with elderly and children, be installed with variable frequency air conditioner, which is not easy to catch a cold. It is recommended to use a constant frequency air conditioner in the living room.
