Guide to HVAC drives for consultants
Published: November 2007
A brochure from ABB highlights the features of motor drives that can help get the best possible performance for an HVAC system. Aimed at consultants, it is called ‘Variable-speed drives for building services: checklist for HVAC consultants’. In recent years, the performance of variable-speed drives has improved dramatically, but ABB estimates that 70% of building-services consultants may not be using the most up-to-date specifications when selecting variable-speed drives for installations. Among the features of many of today’s drives are built-in PID controllers that can cope with demanding pump and fan functions without the added expense of an external controller. The brochure also points consultants towards a complete drive technical specification that can be downloaded from ABB’s website and pasted into any specification. Related articles:
