1) Use ceiling or table fan
as the first line of defence against summer heat. Ceiling
fans, for instance, cost about 30 paise an hour to operate
– much less than air-conditioners (Rs.10.00 per hour).
2) Set the thermostat of the
air-conditioner at 25 degrees centigrade (77.F degree Farenheit)
for least cost. The energy consumption will be three to
five per cent less with each degree about 22oC
(71.5oF).
3) Using ceiling or room fans
allow you to set the thermostat higher because the air movement
will cool the room.
4) A good air-conditioner
will cool and dehumidify a room in about 30 minutes, So
use a timer and leave the unit off for some time.
5) Keep doors in air-conditioned
rooms closed as often as possible.
6) Clean ACs once a month.
Clean filters to enable the unit to cool down quickly and
use less energy.
7) Get your internal wiring
checked by a licensed electrical contractor before installing
an air-conditioner.
8) Contract the NPCL office
and apprise him of the intended increase in load.
