Electronically Commutated Motors Fujitsu brand-Universal motor • Motor Efficiency • Example -Take a typical duty of 190 l/s with an external resistance of 30 Pa the EC solution provides a power saving of 91W and reduces the Specific Fan Power (SFP) from 0.72 to 0.25 W/l/s. Fan coils are often used in office applications where they operate 12 hours a day, 3120 hours per year. Using the above energy saving of 91W, there is an annual saving of 384 kWh and 122kg of CO2. • A typical installation of 500 units will save 61 tons of CO2 per year • System Efficiency • The use of high efficiency EC motors reduces friction and therefore heat. This reduced heat gain can be incorporated at the design stage to reduce chiller, pump and pipe work sizes. A medium sized fan coil unit could save up to 120W through reduced motor heat pick-up. • AC driven fan coils typically operate at a Specific Fan Power of around 0.5 - 0.8 W/l/s. Compliance with the maximum 0.8 W/l/s is dependent on the unit selection and the external static air pressure in the system. EC driven units will operate in a much lower range of 0.25 - 0.45 W/l/s. The reduction of about will greatly assist in the building energy reduction calculations. • Life Expectancy • The reduced friction and heat allow for significantly improved life expectancy of the EC motors when compared to a standard AC motor. By not being subjected to thermal stress the life expectancy is almost twice that of an AC equivalent motor. A quality AC motor would have a life expectancy of approximately 50,000 hours, the EC versions have a life expectancy exceeding 80,000 hours, or over 20 years.
Electronically Commutated MotorsFujitsu brand-Universal motor • SUMMARY • Low energy consumption - up to 60% saving. • Flexible speed control options - easy and accurate fan speed adjustment. • Fully compliant to part L building regulations -half the Specific Fan Power of AC. • High quality long life fan and motor -life expectancy nearly twice that of AC. • Reduced motor heat pick-up - further energy saving on main plant chiller. • No special electrical requirement - units are wired to normal AC 230V mains. • EC fan coil performance as AC - simple selection process. • Set back speed offers further savings of around 25-30% - total energy saving potential exceeds 70% (W) or 50% kVA.
Business Management Capabilities • Software • The host computer software works together with the data logger and can monitor and control all units, including: • On/Off modes • Set Temperature • Swing • Sleep • Fan speed • 365 days timer • Open source protocol allows for integration to different BMS programs. • Open MODBUS functionality up to 2048 units per network (64 sub-groups of 32 units). • Master / slave communication
