Electric Motor Efficiencies and VFD Compatibility
When consulting engineers select and specify fans for HVAC systems, they often specify that the motor for a fan should be a premium efficiency motor. This is critical because most variable frequency drives (VFDs) require a premium efficiency motor. Recent regulations that require engineers to specify premium efficiency motors are discussed.

Engineer's Notebook: Open Cooling Tower Design Considerations
Design decisions made in selecting and sizing cooling towers and their components has a direct impact on the performance of the overall chiller water plant. A cooling tower's long-term performance is a function of the details of design for the cooling tower and its supporting components.
