Summer is definitely a good time to buy air conditioners. When buying air conditioners, will you choose variable frequency air conditioners or constant frequency air conditioners? What is the difference between the two air conditioners? Which one is better to choose when buying?
1. Price comparison between variable frequency air conditioning and constant frequency air conditioning: high frequency conversion
For the same 1.5p air conditioner, the variable frequency air conditioner is hundreds of yuan more expensive than the fixed frequency air conditioner, and the higher the price, the greater the difference.
2. Power saving comparison between variable frequency air conditioning and constant frequency air conditioning: almost
The same is 1.5p air conditioner. The power consumption of variable frequency air conditioner is less than that of constant frequency air conditioner. But the percentage of power consumption is the test data under certain conditions. The owner of air conditioner told me that if the power is really saved, it will be effective if it is used for more than 6 hours. That is to say, the power consumption difference between the same 1.5p variable frequency air conditioner and constant frequency air conditioner is not big. So in order to save electricity and buy frequency conversion students can pass directly. Now it's peak and valley power, and they can't save 1 yuan for a night's driving.
3. Noise comparison between variable frequency air conditioner and constant frequency air conditioner: low frequency noise
The constant frequency air conditioner needs to start and shut down the compressor constantly to adjust the temperature, and the frequency converter is the control system used to control and adjust the speed of the compressor, so that it is always in the best speed state. The frequency converter air conditioner uses a double rotor compressor, which greatly reduces the cyclotron imbalance and makes the vibration of the outdoor unit very small, about 1 / 2 of the conventional air conditioner.
4. Comparison of refrigeration and heating speed between frequency conversion air conditioning and constant frequency air conditioning: the speed of frequency conversion refrigeration and heating is fast
The speed of refrigeration and heating is 1-2 times faster than that of conventional air conditioning. The electronic expansion throttling technology is adopted in the variable frequency air conditioner. The microprocessor can control the opening degree of the valve according to the information collected by the temperature sensors set at the inlet and outlet of the expansion valve and the suction pipe of the compressor, so as to achieve the purpose of rapid cooling and heating.
5. Frequency conversion air conditioner has no hot and cold faults, which is also a great advantage
Summing up the above comparison, regardless of the price factor, the variable-frequency air conditioner is indeed better than the fixed frequency air conditioner, but it's the price difference of hundreds of yuan that makes us tangle. In general, we remember that the main purpose of buying variable-frequency air conditioner is to save electricity, but in fact, it can't save much electricity, so we should choose it based on our own practical situation. My family finally bought one inverter for the master bedroom and two fixed frequencies for the secondary bedroom.
