Some guide lines for your equipment’s used at home to save energy and energy efficient homes.
These are some ways you can reduce higher energy consumption
a) Faulty appliances will
-Refrigerator with faulty thermostat
-broken and defective caskets
– shortage of refrigerant
b) Longer duration of usage of appliances will cause higher energy consumption
c) Old appliances will cause power will cause higher energy consumption
d) small units with an over load will cause will cause higher energy consumption
The energy consumption can be reduced by tweaking the House Hold equipment by:
-
Refrigerator
-it should not be located in a warm place eg near the sun or cooker stove
-there should be adequate space behind the and around the equipment.
-Check the freeze temperature should be at -18deg C
