Mechanical Engineering Project: Solar Energy powered Air Conditioner

[FaaDoO-Engineer]

Description: With Kerala being one of the most humid places on planet earth; Summer, is the time when you wished you had an Air Conditioner. But, you would rather detest the idea because of the staggering electricity bills you would get once you start using the AC. And it would be a miracle if you could use an AC without paying those hefty electricity bills. In that case, it seems a miracle has just happened!

How about utilizing the free energy of the sun to power up your AC?

The hottest months usually, happens to be also the sunniest. You can use the scorching summer heat to actually remove the heat from your room with the help Photovoltaics (PVs) to power your AC. Photovoltaics are collection of cells which have photovoltaic material that makes use solar radiation to develop direct current electricity.

For achieving the best performance the PVs are connected to a solar tracker so as to align themselves towards the sun to receive the maximum amount of solar radiation. The use of a solar tracker would improve the performance of the PVs by whopping 50% in summer.

The use of Concentrated Solar power systems (CSP ) further enhances the utilization of solar power by making use of mirrors to concentrate solar energy onto a photovoltaic cell. Since CSP systems are bigger in construction and expensive they are seldom used to generate power for an air conditioner.

A typical air conditioner consists of the following


1) Condensing coil
2) Expansion valve
3) Evaporator Coil
4) Compressor


Once, the direct current developed by the PVs is fed to the Air Condition unit, you have an Air Conditioner which works on Solar Panels and you can be free from the tension of electricity bills draining your pockets.


Excess power if developed can be used to power other electrical appliance or sold back to a power grid! Ultimately the success of the system would depend upon the cost effectiveness.

The idea is very good

Now the PV cells are old one & they are replaced by FPC & ET/VT in solar energy. If we go for that one, it will be more efficient

Great thought about an a.c. Which works on solar. Apart from csp(concentrated solar power system) , the system can be made more efficient by using the sensors which would automatically rotate the solar panel with the movement of the sun. So good job and keep the user interested by bringing such new & innovative ideas !!!

So improve the design for better efficiency !!!!

wats the solution to the costly installation of the solar panels

good one..nice to know.....

thats a very fantastic idea but there is no download found in here

Hi

The power consumption of an air conditioner is very high. So, the area required for the solar panels makes this unfeasible. It might, however, be easy to make a solar-powered refrigerator instead. That'll be very useful especially in automobiles. What say?

its good job......but u know the ac will be very high power equipment so how can possible the pv will be generated power equal to req. ac power.............tell me

[Rashiaabdulrazak]

Since we are living in the world of increasing atm temp this idea will help a lot and we can reduce the power consumption
