3. Abstract:-
• Demand for electric power is more in summer is concern for most
utilities. However cooling required more amount of water which is
main source as an evaporator, and this only work efficiently when
humidity is low. Evaporating cooling could be a quite common kind of
cooling for the thermal comfort since it is relative low cost and
needed less energy than several different styles of cooling. In our
project, we are using earthen pots and coconut air pad are used for
cooled air. Meeting demand for electrical power throughout peak
periods in the summer may be a major concern for many utilities
within the fast moving world. From the demand points of read on the
grid and value to the consumer, need to quite know install, energy-
efficient evaporative coolers instead of standard air conditioners.

4. • Evaporative cooling is a heat and mass transfer process, that uses water
evaporation for air cooling, in which large amount of heat is transferred from air
to water, and consequently the air temperature decreases. The project deals with
the design and development of low cost mud pot air coolers, which is a type of
Active direct evaporative cooling system, with good efficiency. The aim is to
achieve better Cooling and make the product easily available to different sections
of society at lower cost, as the materials used in the product are mud pots, aspen
wood wool or coconut fiber made evaporative cooling pads. A theoretical model
was developed on python to simulate the results related to the effectiveness of
the design. The product is very low cost as compared to the conventional room
coolers, because of use of mud pot and cost of manufacturing of mud pot is low
at the same time, if this product is made available on large scale can create lot of
job opportunities for regions like rural India.

5. Literature Review:-
• The new model developed is very much cheap than the conventional air
coolers and also very much energy efficient as the use of many systems
such as water distribution system, pump, pads has been completely
abolished and at the same time the ancient mud pots are used to keep the
water in the container cool to increase the rate of evaporation hence to
lower the temperature of air exiting the cooler. Various researchers have
published research papers on Direct Evaporative coolers and indirect
evaporative coolers. The basic idea of swamp coolers is the evaporation
rate, the higher the evaporation rate, the better will be the cooling of a
swamp cooler. Many researches have been conducted that provide the
results that the performance of the swamp coolers depends on the
ambient temperature, the material of the cooling medium, velocity of the
air, area for evaporation. Many materials are also used for developing of
the swamp pads, which can be random media pads, rigid pads which have
their own advantages and disadvantages as stated below:

6. Introduction to Earthen Pot Air Coolers
• Basic components of earthen air cooler:-
1) Clay/Mud body
2) Water Tank
3) Water Distribution System
4) Fan or Blower
5) Vents
6) Float Valve
• Working Mechanism:-

7. • Air enters the duct by fan movement
• Air passes through the evaporative media
• Cool air then strikes the water surface to cause evaporation
• Cool air travels up and comes out
• Applications and Uses:-
1. Residential cooling
2. Remote Villages and rural areas
3. Religious Spaces
4. Green house nurseries.

8. Sustainability and Environmental
Impact:
1. Use of natural materials :- Sustainable sourcing and low
environmental impact.
2. Energy efficiency :- Lower energy consumption and zero to no
electricity dependency
3. Reduction in green house gas emissions :- Unlike traditional air
conditioners that use refrigerants with high global warming
potential, earthen pot air coolers do not rely on such substances,
contributing to a reduction in greenhouse gas emissions associated
with cooling.
4. Water conservation and recycling.
5. Longevity and durability

9. Objectives:-
• The main Goals to achieve in our project are like efficient cooling
with lower energy consumption, and which is accessible and
affordable and should be sustainable. Should also promote water
efficiency and conservation.
• Timeline:- We have started procuring materials for project and when
received all of them we can start our assembling. Whole process can
take about two to three weeks.
• Budget:- Rs 2000-3000
• Outcome of the project:- Issues of climate change tackling, as 95% of
our material are of sustainable products so its highly sustainable
project.
