WO2000035267A1 - Greenhouse roof - Google Patents

Abstract

With the concept, which is depending on the movement of the sun, we can build a multyspan area as in green houses. But the roof would differ as it would have a design that consists of stripes or blades arranged in an angle that allows the sun rays during winter when it comes in an angle to enter through the gap between them. Then the same roof will trap its reflections and when its summer and the sun rays are falling in a right angle only 40 % will be passing through the roof and will be reflecting out straight. That means that the plants will have a cooler summer and a wormer winter with no power 'nor' machines. Also the humidity will not increase, as the air is not locked inside.

Description

GREENHOUSE ROOF

DISCRIPTION IN THE FIELD OF HORTICULTUR GREEN DES RES THE PROBLEM ALL PLANTATIONS IN THE DESERT GETS TOO MUCH HEAT STRESSES FROM THE SUN IN SUMMER AND TOO COLD NIGHTS IN WINTER. SO IF WE COULD STOP 60% OF THE SUN RAYS IN SUMMER AND LET 90% IN WINTER {AND TRAP IT INSIDE}. WE WOULD GIVE THE PLANTS A SUITABLE WEATHER TO GROW HEALTHY.

THE APPLICATION

WHEN WE BUILT A MUALTI SPAN CONSTRUCTION SUCH AS IN GREEN HOUSES OF ALUMINUM, WOOD OR STEEL, THEN PUT UP A TRANSPARENT FIBER GLASS WALL AROUND IT TO ALLOW LIGHT IN WHILE IT STOPS WIND. WITH WINDOWS DESIGNED AS IN PAGE. [6-7 ]LN WHICH WE CAN PUT PIECES OF COAL WITH SPRINKLERS TO WET IT IN SUMMER SO THAT HOT AIR BECOMES COOLER GOING THROUGH IT & CLOSE THEM IN WINTER.

THEN WE ADD THE ROOFTOP ON IT AS LN PAGE [5-7] WITH THAT ROOF DESIGNED OF SLIM {ONE MILLIMETER TO TWO CENTIMETER} PLATS OR SHEETS SPREAD FROM EAST TO WEST. MADE OF ALUMINUM, STEEL OR WOOD EACH SIX ARE ONE ON TOP OF THE SIDE OF OTHER IN SEQUENCE LEAVING BETWEEN THEM EQUAL GAP TO THEIR WIDTH & THEIR SIDES EDGES STARTS AND ENDS ALONG THE NARROWEST ANGLE OF THE FALLING RAYS OF THE WINTER SUN AS IN PAGE.[ 5-7 ] SO THAT WHEN IT IS SUMMER AND THE SUN RAYS ARE FALLING ON THE GROUND IN A RIGHT ANGLE LIKE IN NORTH AFRICA FOR EXAMPLE. ONLY 40% OF IT WOULD ENTER AND REFLECT UP AGAIN. THEN GETTING TO WINTER THE RAYS WOULD FIND MORE ROOM BECAUSE OF ITS ANGLE AS IN PAGE. [5-7JTILL ALL THE STRIPS ARE SHADING EACH OTHER & ALLOWING 90% OF THE SUN RAYS IN AND TRAPPING THE REFLECTION IN BY 60% AND DURING THE NIGHT 60% OF ALL THE HEAT RAYS RISING FROM THE GROUND WILL BE REFLECTED BACK KEEPING THE PLACE WORMIER IN WINTER.

THE ABOVE SYSTEM COULD ALSO BE BUILT OF ANGLED PLATES AS IN PAGE [7-7]

AL THE ABOVE WOULD CHANGE THE WEATHER OF THE DESERT INSIDE IT TO BECOME WORMIER WHEN IT IS COLD OUT SIDE & COOLER WHEN IT IS WORM OUT SIDE WITH NO POWER NEEDED & NO LABOR.

AS WELL AS NO EXTRA HUMIDITY AS THE AIR EXCHANGES THROUGH THE ROOF OPENINGS ALSO AN INSECT PROOF NET COULD BE ADDED UNDER THE ROOF.

GREEN DES RES ROOF DROWING DEAILS PAGE 5-7

1-SUN RAYES ENTERING THROUGH THE ROOF DURING SUMMER AND

REFLECTING OUT STRAIGHT BY 40%.

2-SUMMER SUN RAYS REFLECTING ON ROOF WITHOUT ENTERING THE

ROOF AT ALL BY 60%.

3-WINTER SUN RAYS ENTERING THE ROOF BY 90%.

4-SUN RAYS REFLECTING INSIDE TO THE CIELING AND TRAPED INSIDE BY

60% TO WORM UP THEDES RES.

5- ROOF PLATES MADE OF WOOD, ALUMINUM OR PLASTIC.

Claims

CLAIM

I HEREBY CLAIM THE PROTECTION OF MY INVENTION'S CONCEPT. WHICH IS DEPENDING ON THE MOVEMENT OF THE SUN. & THE APPLICATION WHICH IS: WE CAN BUILT A MULTYSPAN AREA AS IN GREEN HAUSES BUT THE ROOF WOULD HAVE A DESIGN THAT ALLAWS THE SUN RAYS THAT FALLS IN AN ANGLE ONLY TO PASS THROUGH THE ROOF BY 90% BUT IF IT FALLS STRAIGHT IN A RIGHT ANGLE. " MORE IN THE WINTER [90%] THAN DURING THE SUMMER [40%]" WHICH WOULD STOP THE HEAT STRESS FROM HARMING THE PLANTS INSIDE, THIS SYSTEM WOULD BE EFECTIVE IN ALL THE DESERT COUNTRIES.
