What is the difference between inverter air conditioners and ordinary air conditioners? Understand first before buying
At present, the hottest air conditioner on the market should be inverter air conditioners. Whether it is the model of the machine on the market or the promotion of sales personnel, Xiaobian also believes that many people have the question of whether they buy inverter air conditioners or fixed-frequency air conditioners? What is the difference between inverter air conditioners and ordinary air conditioners? In fact, these two issues are very simple. We only need to understand two concepts.
What is a fixed-frequency air conditioner: The fixed-frequency air conditioner we understand means that the compressor inside operates at a constant frequency. For example, in China, the common power supply voltage is generally 220v/50Hz, so the operating power of the fixed-frequency air conditioner is 50Hz.
What is a frequency conversion air conditioner: A frequency conversion air conditioner can adjust itself according to different requirements and the compressor can follow changes in demand. The main reason for realizing frequency conversion is that the electric board of the air conditioner can adjust the power supply voltage, thereby realizing the frequency conversion function.
What is the difference between fixed-frequency air conditioners and inverter air conditioners?
The compressor of the air conditioner is essentially an ordinary motor. The difference is that the inverter air conditioner has an electronic control board, but the fixed-frequency air conditioner does not. Therefore, we can know that the fixed-frequency air conditioner has the following characteristics:
1. Fixed frequency air conditioners have high requirements for voltage stability. If the voltage is unstable or insufficient, its effect will be affected.
2. The displacement of the fixed-frequency compressor is fixed, so the output of cooling capacity is fixed. The compressor will not stop until the set temperature is reached. Therefore, there will be people who are sensitive to temperature who feel cold and hot.
3. The power consumption of a fixed-frequency air conditioner can be calculated according to the data on the nameplate. If the power written on the nameplate is 1050w, then its power consumption per hour is about 1 kilowatt hour.
4. The fixed-frequency air conditioner has a simple structure, relatively mature technology, stable performance, low maintenance costs in the later period, and basically only cleaning will be carried out.
As mentioned above, the main difference between inverter air conditioners and fixed-frequency air conditioners is that the compressor of inverter air conditioners has an electric plate to control its operation, which also leads to inverter air conditioners being able to achieve different cooling outputs. This also leads to inverter air conditioners having the following several advantages:
1. Inverter air conditioners have certain requirements for the power supply voltage. The power supply voltage must be between 170v and 254v to start and operate normally.
2. As the frequency of the compressor changes, its internal cooling output changes with the room temperature. When the room temperature approaches the target, the compressor will operate at a low frequency to avoid excessive indoor temperature changes, and vice versa.
3. Regarding the calculation of power consumption of inverter air conditioners, since the power of inverter compressors is variable, its power consumption will vary in different rooms. In general, the prerequisite for power saving of inverter air conditioners is that the use does not exceed 4 hours.
4. Due to the complex structure of inverter air conditioners, especially the increase of electronic control panels, maintenance costs in the later period increase. The main reason is that the electronic control panels are easy to damage, especially in some small air conditioner dealers, where installation technology is not up to standard can easily lead to damage.
The difference between fixed frequency and frequency conversion of air conditioners is mainly that fixed frequency air conditioners will always operate within the rated range and have certain requirements on the power supply voltage. Frequency conversion air conditioners have low requirements for these, and can even operate at low frequencies, and can be adjusted according to the actual requirements. change. When choosing, you can purchase based on your needs.
