MODEL/PRACTICAL ASPECT

18. DEMONSTRATION & WORKING OF THE PROJECT
 In the energy saving air cooler, the process of production of cool air is
described by the flow chart below.
 As air meets the fabric material the pressure drops which results in
decrease in the temperature. Then as the air enters, the water in the fabric
material absorbs the latent heat of vaporization from air and evaporates,
further decreases n the temperature of the air. The process sequence is
shown below.

20. ESTIMATED COST OF PROJECT

21. Prime Cost
This is also known as direct cost.
Prime Cost = direct material cost +
direct labor cost and expenses
Factory Cost
This is also known as factory cost.
Factory cost = prime cost + factory
expenses.
Total Office
This is also known as selling cost. Total
cost = office cost + selling and
distribution expenses Selling price of
product
Selling cost = total cost + profit
COST ANALYSIS
 One of the major factor
governing this Project is –
 Do not require
maintenance .
 Require only one time
investment.
 The cost of developing this
air cooler is Rs.3270/- ,
which is very low compared
to other commercially
available air cooler.

22. FUTURE SCOPES

23. SCOPE & USES
 Selection of a better fabric which has
high permeability and better capillarity
 Compact the design by reducing the
height of cloth
 designing better duct which has less
frictional loss
 Developing effecting automatic control
for speed regulation and other
functions
 Mainly used in rural areas.
 Also very useful when electricity is not
available.

24. CONCLUSION
 The attempt to design and fabricate an energy efficient
air cooler has been successful.
 The device has been tested for various operating
parameters like Air flow rate, Temperature drop of air
delivered.
 Based on the test, following conclusions are drawn.
• The temperature of the air delivered is lower than the
ambient.
• The air flow is affected by a) Frictional losses in the duct.
b) Low permeability of the fabric .
• The power of the fan is too low hence has not been able to
create sufficient draft of air.
• The weight and volume of the air cooler is very low.
