Compressor frequency is good or frequency conversion is good

When discussing whether the compressor is good for power frequency or frequency conversion, we can compare and analyze from many aspects:

1. pressure stability and regulation flexibility

the variable frequency compressor is opened smoothly through the continuous speed regulation of the frequency converter, and has a good response to the stability of the air pressure. Its displacement range is relatively wide, and the motor running speed can be automatically adjusted according to the actual gas consumption, so as to control the displacement size.

The power frequency compressor is controlled by upper and lower switches. Although its air pressure stability is also good, its displacement is fixed and cannot be flexibly adjusted according to actual needs.

2. start-up impact force and equipment life

the inverter compressor has a soft start function, and the current when starting is small, usually within 1.2 times of the maximum set current, which greatly reduces the impact on the equipment when starting and helps to extend the service life of the equipment.

The power frequency compressor usually has a large current impact when starting, which is generally 6 times the rated current, which may cause certain damage to the equipment and affect the service life.

3. energy consumption and operating costs

inverter compressors can adjust the operating frequency and power according to actual needs, so they are more efficient in energy consumption and help reduce operating costs.

Due to the fixed operating frequency and power, the power frequency compressor cannot be adjusted according to the actual load, which may cause waste of energy consumption in some cases.

4. noise and comfort

inverter compressors usually work in a low-speed environment, and the internal friction of the equipment is low, so the noise is relatively small, providing a more comfortable working environment.

The power frequency compressor may produce large noise due to the fixed frequency and high speed during operation, which affects the comfort of the working environment.

In summary, from the aspects of air pressure stability and adjustment flexibility, starting impact and equipment life, energy consumption and operating costs, and noise and comfort, the inverter compressor has more advantages than the power frequency compressor. However, it should be noted that the price of inverter compressors is relatively high and maintenance may be more complicated. Therefore, the choice needs to be balanced according to the actual needs and budget.
