Dokuz Eylul University - Izmir TURKEY

In this paper, it has been focusing on air-

conditioning, heating, drying with using electrical energy

that produced by the developed design of Solarux system

cheaply.

The Purpose Of Study


The aim of this invention is to use planar mirrors instead

of parabolic mirrors and to replace the disadvantages of

mirror system and to get the advantage for manufacturing

and stability in the terms of engineering.



For this purpose, for the development and design of

Solarux system Solid Works 2012 has been used and the

results are discussed and shown briefly



Other Systems

Parabolic Trough

Based on reflectors

that are long, narrow

and have a single

axis tracker to follow

the sun.


Other Systems

Power Tower

Solar power tower, also

known as central tower power

plants or heliostat power

plants is a type of solar

furnace using a tower to

receive focused sun light.


Other Systems

Dish EngineBased on reflection

of sun light to a

cavity receiver at the

focal point by small

units which shapes

like a dish when they

join each other.


Other Systems

Fresnel System

Used as solar condenser.The

reflectors are consisting of

many long row parts of

mirrors and they reflect

beams to a receiver where

beam radiation are

concentrated.


Solarux CSP is an

invention which has some

similarites with power

tower technology.It is

based on solar radiation

that is used for producing

steam or hot air for

producing electricity as

well.

Engineering Enviroment Cost


The invention is based on a dish mirror system which

includes planar mirrors that reflect sun light to an absorber

(heat-exchanger) in order to produce heat energy in high

temperatures.

The flexural tests are carried out

by using three point bending

specimens and the flexural

property was determined

according to ASTM D790 with the

specimen dimensions of 42 mm

diameter, support span of 160

mm and crosshead speed of 0.5

mm/min. The Flexural test using three point

bending specimen



As a result of these experiments it

is obtained that the specimen 4

shown in Figure 4 has the

highest-strength when compared

with others since the cement and

glass fiber filaments are

distributed more homogeneously

and especially fiber effective on

the strength.

OLD DESIGN NEW DESIGN

What’s New Comparison-Mirrors

In old design, the amount of

mirrors are 96 pieces with

4m dish diameter.

In new design, the amount

of mirrors are 150 pieces

with 5m dish diameter. (6m

with photovoltaics)



What’s New Comparison-Mirrors

In old design, mirrors are

bonded to grippers.This

procedure may cause the loss

of mirror because of adhesive

problem

In new design, mirrors can be

connected by using skrewed

rivet at the center and washer

at the mirror edges to the

gripper


What’s New Comparison-Cleaning System

NEW DESIGN



What’s New Comparison-Pipe Route

In the old system main pipe

which is connected with

exchanger passed into a mirror

because of the plate which

holds the mirror grippers.

In the new design , the plate is

removed and replaced with skrewed

rivet elements.So main pipe can

pass from the center of the dish.By

making this replacement , the

fracture of a mirror is prevented.



What’s New Comparison – Vertical Movement Shafts

In the old system there was

only two shaft that helps to

move dish up and down.

In the new design there is

four shafts in order to

prevent the system from

buckling caused by wind.



What’s New Comparison – Dish Design

In old design, the weight

of dish frame is high

because of grippers

, gripper covers etc…

In new design, frame

becomes more simple

because of changing its

design ?



What’s New Comparison – Mirror Grippers

In the old system these

grippers were designed as an L

beams and a supporter rod.In

addition, there was a lot of

pieces of connection parts in

order to hold mirrors.

In new design dish gripper is

constructed as some kind of

profiles and also designed

for acting as a route for

cleaning system.



What’s New Comparison – Dish Grippers

Old grippers were designed

as on L profile beams and a

supporter rod.

In new design, instead of L

profile; we have rectangular

profiles which has less weight

than the old one.



What’s New Comparison – Vertical Plane

In old design, vertical plane

has a polygon structure

obtained by connecting

profiles with interconnection

elements

In new design, in order to

provide more rigidity, close – fit

sheets are designed



What’s New Comparison – Horizontal Plane

In old design, vertical plane

which includes beams

obtained by connecting

profiles with interconnection

elements

In new design , in order to

provide more rigidity, close – fit

sheets are designed.In

addition, shaft at the center

provides the rotation movement

and also covers the flex pipe

and cables.



What’s New Comparison – Upper Tower

In old design, upper tower has

a circular shape and just like

planes, there is a weight

problem.

In new design, upper tower

has three floor and the weight

problem is solved by using

sheets in each floor.



What’s New Comparison – Breaking System

In the old system, clutch

disc is used due to

regulate speed

In new design, a system which

includes a circular profile, nuts

and bolts are used for

regulation of speed.



What’s New Comparison

In old design, lower tower

was constructed by steel that

caused a weight problem.

In new design, lower tower

constructed as an composite

which includes cement – fiber

glass.Therefore system becomes

more lighter than the old one.

Solarux CSP-Fresnel System


Comparison With

Other Systems

1. Mirrors are flat

2. Two axis – direction exist

3. No loss efficiency because of the

distance between absorber and

mirrors (approximately 5m)

4. The deviation of solar in the

absorber doesn’t exceed 1-2 cm

5. It has vacuum which prevents heat

loss at absorber in Solarux CSP.

6. Construction site

The Advantage Of Solarux System

More efficient than parabolic and

fresnel systems


Conclusion

• Solar flat mirror is a renewable system which based on sun light and it’s

reflection

• System can provide and store a valuable energy and use it whenever you

want.

• The electrical energy can be provided without pollution and it can be

used even at night

• This system also can be used for agricultural heating process and drying

process.

• It will contribute to the country's economy and also has the scientific

application capability, manufacturability and in addition, it can be highly

desirable in terms of sensitivity to the environment


Conclusion

• Have good financial results, the good construction, performance, work

place or home budget, environmental cleanliness, cleanliness of the

system itself, and in many respects quite good security features and

efficiency

• The only disadvantage of Solarux CSP is the efficiency of the system

varies depending on region. Because the incident angle of the sun

coming around the world is crucial.
