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
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.
