In May, the headquarters and each subsidiary conducted daily collection and statistical analysis of energy data. The analysis revealed that the electricity consumption of public auxiliary equipment accounted for as high as 80%, with the dehumidifiers and accompanying chillers in the dry rooms being particularly prominent.

In August, the Engineering Center, as a pilot, proposed strategies for energy conservation and emission reduction:

Where feasible, experiments are scheduled in a concentrated manner to reduce the use of dehumidifiers and maximize energy savings.

• Centralized Use of Equipment

For experiments involving large equipment that is not easily movable, they are concentrated in laboratories served by the same dehumidifier to avoid the simultaneous operation of multiple devices, thereby saving energy.

• Staggered Use of Laboratories

If dehumidification is required in each laboratory, the use of laboratories is staggered, employing peak and off-peak pricing strategies to save energy and reduce costs.

Laboratory managers are required to record the operating hours of dehumidifiers for the week and plan the use of laboratories in a coordinated manner to avoid idle operation of equipment and improve equipment utilization.

• Adjust Dehumidifier Parameters

Under the guidance of the manufacturer, the regeneration temperature and return air dew point of the dehumidifiers were adjusted to control the room dew point between -40℃ and -45℃, significantly reducing heating energy consumption.

• Adjust Chilled Water Outlet Temperature

The outlet temperature of the chillers was also adjusted to operate under energy-saving conditions, avoiding energy waste.

After nearly a month of energy statistics, daily energy consumption has decreased by about 20%. This has not only effectively reduced the energy consumption of the Engineering Center but also laid a solid foundation for the company's sustainable development.
