Combat rising HVAC energy costs Building owners and facility managers are continually look for ways to save energy and money. Recent government regulations and the rising popularity of the “green building” concept have led to highly energy-efficient new building, but what about older buildings, and will retrofit projects that achieve energy efficiency to […]
The advanced optimum excitation control (AOEC) in Mitsubishi Electric’s FR-F800 series inverter drives continuously adjusts the excitation current to an optimum level providing highest motor efficiency. The newly developed AOEC, provides a large starting torque while maintaining the motor efficiency throughout the speed range. This is done without the troublesome adjustment of acceleration/ […]
ABB says HVAC drives applications are more than just a change of speed. VSDs from every manufacturer and reseller can be applied to HVAC installations and will save energy over fixed speed motor drives. Like most applications however, HVAC invariably requires more from the drive than simply varying the speed. According […]
When should we replace our working VSDs? When to replace existing VSDs is an important decision for many organisations. Modern variable speed inverter drives (VSD) are very reliable. With earlier drives, the two biggest weaknesses were the cooling fans and the power capacitors, but in newer products, these components are designed to have […]
New ABB variable speed drive brings intelligent climate control. HVAC systems require intelligent fan control for proper airflow to protect the products and the people. Modern buildings rely on controlled airflow for productivity through comfort. In addition, precise control of pumps ensures water and piping systems provide consistent and fine-tuned climate control, and […]
