Energy Saving Parameters for Facility Managers

The training covers the energy-saving parameters that equipment managers need to master, including equipment operation modes, power consumption thresholds, and smart scheduling strategies.By using reasonable energy efficiency parameters, not only can energy consumption be reduced by 20-35 %, the lifespan of equipment can also be extended, helping companies achieve their goals of green operations.

Why is parameter adjustment the lifeblood of energy conservation?

Don't underestimate these parameters hidden in the background of the equipment. They are like invisible switches that control energy consumption.For example, last year a certain factory adjusted the threshold values of the pressure parameters of its air compressors, and saved more than NT $ 800 a month in electricity per machine.The job of the equipment manager is to figure out the key numbers that affect energy consumption, and find the optimal balance between efficiency and energy conservation.

These are the three core parameters that must be closely watched.

Choosing a management model.

Most modern equipment has options such as "intelligent mode," "economy mode," and "standby mode.For example, variable frequency air conditioners can automatically adjust the speed of their compressors according to room temperature, saving 30 % or more energy compared to fixed frequency models.But be aware that some equipment is set to high performance by default, and must be manually switched to energy-saving mode.

Set the sleep threshold.

Idle equipment consumes the most electricity, so you should set printers, lathes, and other such intermittent-use equipment to go into standby mode after 10-15 minutes of inactivity.There's a little trick: You can make the time it takes the phone to wake from sleep shorter, and this will not affect the user's experience and will save power.

Power dynamic adjustment.

Equipment with load regulation functions needs to be closely watched.For example, the most efficient operating point for a chiller is usually 70 % to 80 % of full load. Setting the parameters within this range is more energy efficient than full-load operation, and more efficient than low-load operation.Remember to combine production planning with dynamic adjustment, so that the equipment is not left in a state of "starvation" for long periods.

It's easy to fall into a trap of misallocation.

He has seen too many managers adjust the parameters too aggressively, with the result that the equipment is constantly starting up and shutting down, and actually consuming more electricity.For example, for large power-consuming equipment like elevators, the on-off intervals should be no shorter than 30 minutes.Another thing to keep in mind is that the temperature difference between the set point and the actual temperature should be set 0.5-1 ° C higher in summer than in winter. This will prevent the compressor from starting and stopping repeatedly.

Figures speak for themselves.

After setting the parameters, don't be in a hurry to wrap things up. Install an intelligent meter and monitor usage for a few days or a week.The important thing is to see if the utilization of off-peak electricity has improved, and to compare the change in the energy consumption curves under the same operating conditions.Once, after adjusting the parameters on a forklift, I found that the peak morning power consumption had dropped by 40 %.

Finally, it is recommended that the parameters be recalculated once a quarter.In particular, after a production line has been reconfigured or upgraded, the original energy-saving equipment may no longer be appropriate for the new operating conditions.Only by forming the habit of regularly optimizing parameters can the energy-saving effects be sustained.
