If your computer must be left on,always ensure to turn off the monitor as this device alone uses more than half the system’s energy and consumes more power.
Improvement of power factor from 0.85 to 0.96 will give 11.5% reduction of peak KVA and 21.6% reduction in peak losses. This corresponds to 14.5% reduction in average losses for a load factor of 0.8.
- Install automatic on-off switching of cooling tower fans and save upto 40% on electricity costs.
Blocked filters increase fuel consumption of dg sets by 2gm/kWh
Use of sodium vapour lamps for area lighting in place of mercury vapour lamps saves electricity upto 40%.
Improve insulation if the surface temperature exceeds 20°C above ambient. Studies have revealed that heat loss form a furnace wall 115mm thick at 650°C amounting to 2650 kcal/m2/hr can be cut down to 850 kcal/m2hr by using 65 mm thick insulation on the 115 mm wall
Select a pump of the right capacity in accordance with the requirement. Improper selection of pumps can lead to large wastage of energy. A pump with 85% efficiency at rated flow may have only 65% efficiency at half the flow.
Use of PVC fills in place of wooden bars results in a saving in pumping power of upto 20% in cooling tower.
