BP21 - VSD for chilled water pump
| Address: Ben Luc District, Long An Province | |
| Project Summary: A textile and dyeing enterprise in Long An Province has installed variable speed drive (VSD) for chilled water pumps, reducing pump speed and saving power consumption. | |
| Year of implementation: 2019 | |
|
Status before implementation The number of looms changes based on the production volume, and the environment temperature changes over time. Chilled water pumps, condensate water pumps and cooling tower fans were operating at a steady speed. However, the actual load varied with the production output and time. The working capacity of the chilled water pumps was 8.9 kW.
Chilled water pumps
The factory may consider installing a VSD for the secondary pumps. |
Result 2 VSDs (18.5 kW) have been installed for 2 secondary chilled water pumps. The operating capacity is 4.9 kW.
The inverter has been installed Thus, savings rate is about 44% after installation (the rate is also affected by changes in cold load and outdoor temperature). |
