There are fixed-frequency and inverter air conditioners, which one should we choose when we buy an air conditioner? How to distinguish between fixed frequency air conditioners and inverter air conditioners? Which is better, fixed frequency air conditioner or inverter air conditioner? Today, I carried out a comparative analysis between fixed-frequency air conditioners and inverter air conditioners from various aspects, take a look.
1, the working principle of comparison
Fixed frequency is when you set a room temperature, before you set the room temperature has not reached the compressor has been working non-stop, and so on to reach the set room temperature after the compressor stopped working, and so the room temperature back up 2-3 degrees and then restart the compressor (outdoor unit), restart the compressor noise is somewhat large, but it depends on whether the outdoor unit installation location is reasonable.
But the inverter will not appear this situation, the inverter is in the set room temperature after the compressor high-frequency operation can quickly reach the set room temperature, to set the room temperature after the compressor becomes low-frequency operation, the compressor to different frequencies to reach the set temperature, and then this conversion process indoor constant temperature effect is good noise low.
2, power saving comparison
If the air conditioner is installed in the living room and the use of time is not long or buy fixed-frequency, because inverter machine for a short time does not save electricity.
Of course, the bedroom should be installed inverter air conditioning, because the bedroom is generally the whole night on.
The temperature will reach a very small power to maintain, can reflect the energy-saving power saving.
3, the use of a sense of contrast
Also because the inverter is not like the fixed frequency machine to start and stop to maintain the temperature, inverter is always stable small power operation, so you do not feel the cool breeze when the machine is on and off when the heat, more comfortable.
From the overall point of view, or inverter good, because it will be based on the indoor set temperature changes to adjust the speed of the compressor, the temperature rises, the compressor will run at high speed to increase the cooling capacity, and vice versa to reduce the speed to reduce the cooling capacity, there will be no sudden cold and hot phenomenon.
4、Price comparison
The same horsepower frequency conversion than fixed frequency thousands of dollars, fixed frequency price than the price of frequency conversion is relatively obvious advantage; fixed frequency price is more affordable.
5、Contrast summary
According to the actual use of the situation to decide, under the conditions of adequate budget, buy frequency, for the family economic conditions do not allow the case to buy fixed frequency is more appropriate.
