Green Products for Energy Efficiency

1. Green Products for Energy Efficiency

2. Energy Conservation In OECD countries Electric motors account for 65% of the electrical energy consumed In India it is about 60% Motors consume more energy because: Most of them are fixed speed type irrespective of load requirement The smaller ones are inherently less efficient They are over-designed for large voltage fluctuations that occur in weak grids New generation Permanent Magnet motors are more efficient and flexible for speed variation, which gives rise to enormous power/energy savings

3. Solutions • Deltec has solutions for motor/generator controls in India for: • Energy Efficiency • Renewable Energy • The major product segments addressed are: • White Goods & Home Appliances • Industrial Equipments & Appliances like: • Pumps, Fans, Blowers, Compressors • Portable Electric Tools • Textile Spinning Machinery Drives • Solar Inverters & UPS • Generator & Controls for Micro Wind, PICO Hydel and Biomass Gas Engine Energy Systems

4. Description of Technology • All motorized appliances run directly from AC Mains/PV panel - do not need inverter • High Efficiency, BLDC, PMSM, SR motors are used • The appliances are operated in a variable speed mode, matching the motor torque to that demanded by the load at different speeds • State of the Art “Sensorless Vector Controls” is used which give: • The lowest current drain • And hence suitable for Solar/Battery energy sources

6. Advantages of Technology • Power rating of the solar panel comes down drastically, almost by a factor of 2 • Reduced capital costs • Appliances can run from AC mains if solar light is not available • Incorporation of MPPT results in: • Maximum power available in the panel is used • 20% extra power yield from the panels under cloudy conditions • Output Voltage & Frequency are kept constant irrespective of climate conditions or load • Wide variation in input power supply voltage in case of AC Mains operation

7. Inverter Air Conditioner • More than 50% Energy Savings • Wide variation in input supply voltage 170 ~ 270 V

8. Inverter Refrigerators • More than 60% Energy Savings • Wide variation in input supply voltage 100 ~ 270 V

9. Energy Efficient Ceiling Fan • Consumes only 30 W as against • 80~ 100 W for existing commercial type • 50 W for 5 Star rated ones by BEE • Sensorless Control gives increased reliability • Ideal for Schools, Offices which work mainly in the day time • IR/RF remote for speed changing • Smaller motor with lower weight • Very low motor heating due to lower losses

10. Ceiling Fans

11. Complete Kitchen Machine • Combines the operation of Mixer/Blender, Wet Grinder & Atta Chakki • Brushless SR Motor – highly efficient & reliable • Direct drive of attachments – no belt/gear box • Low speed/high torque for wet grinding • High speed/low torque for Blending/Mixing • Common platform and different attachments • Consumes less than 50% power/energy in all modes of operation compared to existing appliances
