Originates with thethermonuclear fusionreactions occurring inthe sun.

Represents the entireelectromagneticradiation (visible light,

infrared, ultraviolet, x-rays, and radio waves).

The surface receives about 47% of the total solarenergy that reaches the Earth. Only this amount is

usable.

The principle behind (solar) thermal driven coolingis the thermo-chemical process of sorption.A liquid or gaseous substance is either attached to a

solid, porous material (adsorption) or is taken in by aliquid or solid material (absorption).

The sorbent (like silica gel) is provided with heat(i.e. from a solar heater) and is dehumidified.

Solar heater will be used to produce steam/ hot water as afirst step. This circuit is shown in Blue colour. This is a closedloop. Same water is circulated. There is no external electricalheat used.

The steam passes through the absorption chiller, loses itsheat to the Refrigerant (Lithium Bromide/Water solution) andreturns to the tank for recirculation again.

Refrigerant ( Shown in Orange takes the heat from the steamand using the adsorption cycle explained in the write up,produces chilled water from the second loop of water enteringthe Absorption chiller.( Shown in Green.)

The chilled water passes through the Heat exchanger, and

cools the air to the required temperature, that in turn coolsthe target room.

The chilled water stored in the tank is increased tocontinue cooling during the hours when the sun is notshining. It also acts as the buffer for the times when thecloud or other factors affect the amount of heat from thesun.

Construction of solar water heater using Aluminumtube.Construction of Absorption chiller system .Implementing the water heater system to AC system

requires additional Mechanism .It is to overcome demand for Ac needs at low cost .

This project is an innovation in itself, In solar water heatercopper is replaced by Aluminum tubes .


10/11

Since this challenge involves many issues like

accuracy , reliable and usability of theAluminum in solar heater that are not used incurrent technology.The system designed has been focused onusability of the renewable source of energy .We have devised an indigenous way to Using

solar energy to run AC.

No external electrical heat is required.Cost effective , efficient , user friendly , ecofriendly , precise and accurate.


11/11

A market survey has been conducted and it was found thatno such Concepts exists as our implementation. We are proud to mention that this idea is completely

innovative and it is very effective.We have adopted a new technique that runs the AC.Our product is Cost effective and the market responsemay exceed 85 %.
