3. Appliances-electrical or mechanical-that are
used for household functions are termed as
household appliances.
These can be classified into two categories:
Major appliances
(AC,Refigerators,Washing
Machines)
Minor appliances
(TV,Mixers,Water Pumps Etc)

5. Components of a Refrigerator
There are five basic parts to any refrigerator
Compressor
Heat-exchanging pipes - serpentine or
coiled set of pipes outside the unit
Expansion valve
Heat-exchanging pipes - serpentine or
coiled set of pipes inside the unit
Refrigerant - liquid that evaporates inside
the refrigerator to create the cold
temperatures

6. Don't put the refrigerator near a heat source - an
oven, the dishwasher or direct sunlight from a
window.
 Make sure air can circulate around the condenser
coils. Leave a space between the wall or cabinets.
 Keep your refrigerator's coils clean. Brushing or
vacuuming the coils can improve efficiency by as
much as 30 percent.
 Check door seals to make sure they are airtight. To
test them, close the door on a dollar bill and try to
pull it out. If the dollar slides out easily, kiss that
dollar away because you're wasting energy and
money by letting cold air leak out!

7. Water heating is the third largest energy
expense in your home. It typically
accounts for about 14% of your utility
bill.
 A family of four, each showering for 5
minutes a day, uses 700 gallons of water
a week; this is enough for a 3-year
supply of drinking water for one person.

9. •High parasitic loads.
•Meter read wrong.
•The addition of major appliance.
•Additional occupants.
•Faulty appliances (pump or thermostat).
•Seasonal appliances (pool pump, heat tape).
•Bad connection causing leakage to ground.
•Duelling thermostats.

11. Use of a Variable Speed Drives
•
The VSDS in motor control could further improve energy saving. The
motors of pumps, fans and air compressor represent an important item of
energy consumption in the plant.

12. •The losses through the conductors (for example, cables, bus
bars) could be reduced by installing slightly larger size
conductors since larger size conductors have lower
impedance.
•Typical conductor losses are 1.5%.
•The losses in the conductor can be calculated as well. For
example, cable resistance is 0.0984 Ω/ km, while the
estimated cable length is 160 m which means that resistance
is 0.0157 Ω.
•Cable losses can be obtained by the I2R formula.

13. Lighting energy use can be substantially reduced by:
•Day Lighting
•Installing efficient lighting devices such as LED,
CF, and fluorescent lights).
•Task Lighting
•Controls: Developing habits of turning off lights
when not needed (or using motion, heat or light
sensors to control when lights are on or off).

18. The Three R’s...

19. Reduce Reuse Recycle
•The three ‘R’s are ‘
’, ‘
’ and ‘
’.
•‘Reduce’ is the main part being targeted with the aim of reducing
consumption of energy and resources. And by virtue of reduced
consumption, there is also less waste being generated which needs to be
disposed of.
•Next is ‘
’ which is targeted for waste materials which are unavoidable
by-products of industrial processes or human consumption. Waste materials
which cannot be reused will be recycled.
•Among the three,Recycling is the least emphasized because after
substantially reducing consumption, and reusing the wastes and byproducts, there would be very little left to recycle. Moreover, recycling is not
completely an environmental friendly process because it requires energy to
convert it into another form.
Reuse


Energy Guides labels be placed on all new
refrigerators, freezers, water
heaters, dishwashers, clothes washers, room
air conditioners, heat pumps, furnaces, and
boilers.
EnergyGuide labels show the estimated
yearly electricity consumption to operate the
product along with a scale for comparison
among similar products

23. 
An energy-efficiency rating scheme for Electrical
appliances/Buildings .
 rating will grade Equipments/ Buildings on their
The
energy efficiency, starting from one star for the least
energy-efficient, and going upto five stars, for the
most
energy-efficient.

Star Labels have been created to standardize the
energy efficiency ratings of different electrical
appliances and indicate energy consumption under
standard test conditions.

24. The Bureau of Energy Efficiency has developed a scheme for energy
efficiency labelingof equipments,in MAY2006.
Under this scheme, the following equipments have been star rated.
1. FrostFree (No-Frost) refrigerator ***
2. Tubular FluorescentLamps ***
3. RoomAirConditioners ***
4. DirectCoolRefrigerator
5. Distribution Transformer ***
6. Induction Motors
7. Pump Sets
8. CeilingFans
9. LPGStoves

25.  provide information on energy performance
To
so that consumers can make informed decisions
whilepurchasing appliances
 make aware the consumer about the energy
To
saving potential among the availableproducts
 cost saving potential of the marketed
The
household andother equipments
 create a demand in the market for Energy
To
Efficient equipments.
