Air conditioning has fixed frequency and frequency conversion. When we buy air conditioning, which one should we choose? How to distinguish between fixed frequency air conditioning and variable frequency air conditioning? Fixed frequency air conditioning and frequency conversion air conditioning which good? Today, Xiaobian has carried out a comparative analysis between fixed frequency air conditioning and frequency conversion air conditioning from many aspects. Let’s take a look.
1. Comparison of working principles
Fixed frequency is when you set a room temperature, before you do not reach the room temperature you set the compressor has been working, and so on to reach the set room temperature compressor stop working, such as room temperature rise 2-3 degrees and then restart the compressor (outdoor unit), restart the compressor noise, but it depends on whether the outdoor unit installation position is reasonable.
But this will not happen with frequency conversion. Frequency conversion is that after setting the room temperature, the high frequency operation of the compressor can quickly reach the set room temperature. After reaching the set room temperature, the compressor runs at low frequency, and the compressor reaches the set temperature with different frequencies.
2. Comparison of power saving
If the air conditioner is installed in the living room and not used for a long time, or buy a fixed frequency, because the frequency conversion machine is not used for a short time to save electricity,
Of course, the bedroom should be installed frequency conversion air conditioning, because the bedroom is generally on all night.
After the temperature is reached, it will be maintained with a very small power, which can show energy saving.
3. Use a sense of contrast
Also because the frequency conversion machine is not like the fixed frequency machine to open and stop to maintain the temperature, the frequency conversion machine is stable and small power operation, so that you can not feel the cool wind when the boot and the stuffy when the stop, more comfortable.
On the whole, frequency conversion is better, because it will adjust the speed of the compressor according to the change of the indoor set temperature. When the temperature rises, the compressor will run at high speed to increase the cooling capacity, and on the contrary, the speed will be reduced to reduce the cooling capacity.
4. Price comparison
The same number frequency conversion is more expensive than fixed frequency thousands of pieces, fixed frequency than frequency conversion price comparative advantage is more obvious; Fixed frequency is more affordable,
5. Comparison and summary
According to the actual use of the situation to decide, under the condition of sufficient budget, buy frequency conversion, for the family economic conditions do not allow to buy fixed frequency is more appropriate.
