Technical report HLH Issue 06 | 2025 Saving electrical energy in HVAC systems by optimizing the number of fans

Regulating volume flows according to demand makes it possible to save energy.

In addition to the design point, further savings effects in HVAC systems and devices are particularly relevant in partial load operating cases.

The current technical report follows on from the first article, “Saving electrical energy by optimizing the number of fans used.” (Available here on the homepage under Technical Articles / HLH 09 | 2024 dated December 17, 2024)

The second part describes the possibilities for optimizing efficiency in partial load operation.
