Carry out energy-saving renovation of fans.
For fans that have been put into operation, the efficiency of the fans can be tested. For fans with lower efficiency, you can consider modifying them in the following ways to achieve the purpose of saving energy.
- For fans whose actual operating point deviates far from the design point, a more effective energy-saving modification method is to add a variable frequency drive. The modification is relatively simple, and the energy-saving effect is obvious. However, when performing frequency conversion modification, pay attention to the issues mentioned above.
- For fan equipment with backward technology, you can consider replacing the entire machine with high-efficiency equipment. During the renovation, the fan inlet and outlet air ducts can be reused, and the basics can be adapted to new equipment with slight modifications. According to experience, when high-efficiency energy-saving products eliminate products with backward technology, the investment payback period is generally about three years.
- For fans whose actual operating point deviates slightly from the design point, the rotor or blades can be replaced to improve the efficiency of the fan.
- For occasions where the loss of the fan system is large, you can consider adding guide vanes to the air ducts and elbows to reduce the airflow loss, thereby achieving the purpose of energy saving.
Improve the management level of high-end equipment operations!
Good equipment requires good management. Improving the management level of equipment operation is also critical to giving full play to the advantages of the equipment and improving the efficiency of equipment operation. It is recommended that enterprises start from the following aspects to strive for precise planning and on-demand ventilation. Avoid unnecessary waste of energy.
- Carefully arrange production, rationally control fans, and strive to achieve on-demand ventilation.
- Improve the professional level of equipment managers.
- Optimize the system to avoid unnecessary increases in system resistance.
- Equipment maintenance must be in place and management concepts such as “make do” should be avoided.
