Optimizing an HVAC system
3 Ways To Increase Chiller Efficiency VFDs, parallel devices, and increasing supply temperatures all contribute to energy savings for chiller plants. By Thomas Squillo HVAC
- Consider variable speed retrofits Most components within a chilled water system will benefit from variable speed drives. In fact, most current energy codes require VFDs for these components in new systems and major retrofits. VFD costs have also decreased dramatically in the last several years. As shown by the constant- and variable-speed chiller efficiency charts on page 38, there is a huge benefit to VFDs for chillers,...
