Everyone knows that inverter air compressors can save energy, so why can inverter air compressors save energy? The editor of JOY Machinery (Shanghai) Co., Ltd. specially summarizes it for you as follows:
1. Since it is not excluded that the compressor will run at full load for a long time, the motor capacity can only be chosen according to the maximum demand, so the design capacity is generally too large, which wastes energy. In actual operation, the air compressor will not always run at full capacity. If the inverter air compressor is used, the work efficiency during operation can be greatly improved, and a lot of power can be saved.
2. Because the variable frequency air compressor makes the pressure on the pipe network stable, it can reduce or even eliminate the pressure fluctuation, so that all the running air compressors in the system operate at a lower pressure that meets the production requirements, reducing the pressure caused by upward pressure. power loss.
3. The pressure setting of the variable frequency air compressor can be a fixed value, that is, the minimum pressure that meets the requirements of the production equipment can be used as the set pressure. The speed of the air compressor even eliminates the unloading operation of the air compressor and saves electricity.
4. Some adjustment methods (such as adjusting the valve opening and changing the angle of the blades, etc.) cannot reduce the operating power of the motor even when the demand is small. After the frequency conversion speed regulation is adopted, when the demand is small, the speed of the motor can be reduced, and the operating power of the motor can be reduced, thereby further realizing energy saving.
5. The power frequency air compressor cannot be continuously adjusted according to the load. After adopting the frequency conversion speed regulation, it can be very convenient to carry out continuous adjustment, and can maintain the stability of parameters such as pressure, flow, temperature, etc., thereby greatly improving the working performance of the compressor.
The inverter air compressor saves energy by 10%~35% compared with the ordinary air compressor. The specific energy saving depends on the working conditions of the air compressor and the parameter settings of the inverter. The biggest influencing factor is the working condition of the air compressor. Under normal circumstances, the greater the fluctuation of the air consumption, the more obvious the energy saving effect, or the greater the proportion of the no-load time to the total working time, the greater the energy saving. more obvious.
JOY Machinery frequency conversion air compressor series, including ordinary frequency conversion screw air compressors, permanent magnet frequency conversion screw air compressors, two-stage compression permanent magnet frequency conversion screw air compressors, etc. Inverter air compressor series motors operate at ultra-low temperature to avoid high temperature demagnetization. When the air supply is not large, or the air is not needed, the system will enter the sleep mode to achieve maximum environmental protection and energy saving. In the dormant state, when the specific working pressure reaches the dormant state and arouses the working pressure, the inverter responds at a high speed and runs immediately. Save up to 40% of unnecessary energy waste:
An example of power saving: a 75KW general air compressor runs 8,000 hours a year, and the electricity bill is 0.7 RMB/kWh, and the annual electricity bill is 75KW*8000*0.7=420,000 RMB. JOY's permanent magnet variable frequency air compressor can save about 40% of electricity in one year, then more than 420,000 RMB * 40% = 168,000 RMB
