VSD Operation Examples
Application and Examples
* Load rate : 76.7%
* Total electric consumption :
- Load electricity : 89.2%
- Unload electricity : 10.8%
* When adopting VSD vs. the standard 10.8% more energy saving compared with the same input condition
* Target pressure setting additionally reduces the energy by 5% of the compressor capacity.
Controller for Inverters
* Controlling the speed of motors in accordance with the demand for compressed air
* Using text messages to show the condition of the compressor and inverter
* Strengthening the resistance force against noise by suing products that have passed EMC tests
Effects of the VSD Screw Compressor to Save Energy
* Saving electricity during unloading operation : Free changes in speed is quickly and precisely performed to meet the changes in the amount of air needs by the system.
* Required compressed air equals the amount of compressed air produced : The loss of energy caused by the production of unnecessary comperssed air can be prevented.
* Setting the target pressure so as to reduce electricity : VSD screw that can control constant pressure. The minimum pressure required by the system can be set, and the compressed air (target pressure) energy can be saved in accordance with the demand from the system. If the target pressure is set, the electricity can be additionally reduced per 1 bar by 5% of the capacity of the compressor.
* The soft start through the inverter prevents the loss of electricity caus-ed by the overshoot of the electric current during operation and redu-ces the stress on the operating motors (extending the life of montors).
Applocation of VSD Screw Compressor
* The system has a big variation in air consumption.
1. System with a big variation of the amount of compressed air during operation.
2. System with a big variation of the amount of compressed air during night and day time.
3. System with monthly or seasonal variation of the amount of compressed air.
* A plan has been made to multiply facilities on the production lines.
* Large capacity facilities to operate many compressors at the same time : Standard Screw (=Base Load) + VSD Screw (=Top Load)
1.A precise system needs to have a small range of pressure changes
2.The system requires a certain type of constant presure when compressed air is consumed.
Option
* 10" Touch Screen
1. The condition of the operation can be easily recognized.
2. A journal does not have to be kept to record the operation. (The records can be stored in an excel file after the data has been backed up.)
3. The environment can be set, operated, and maintained without special know-how.
4. Trends in the use of compressed air can be (daily, weekly or mon-thiy) analyzed by referring to graphs.
5. Scheduled operation is possible.
