First, we will explain all the parts of this system, and in the middle of the explanations, we will also describe the mechanizedenergy saving curtain and Inside Shading.

mechanism of energy saving curtain

 

What is an energy saving curtain and what is its use?

The material of these energy storage curtains or thermal curtains is synthetic yarn or plastic tape in addition to aluminum tape, which the combination and thickness of these threads and plastic tapes cause variety in these curtains, which of course will change their efficiency.

In general, Siving energy curtain can be said to be the best complement to greenhouse cooling systems, the use of which not only reduces the costs and energy needed to cool the greenhouse by up to 50%, but also the cost of purchasing heating systems and the amount It also reduces fuel consumption by the same amount. And it can even be said that this system can increase production by up to 30%. It also saves water consumption in the main crop and facilities.

These thermal curtains can be open or closed in relation to the possibility of air passing through aluminum strips.

Open aluminum curtains have the advantage of allowing air to pass through the strips and evaporating moisture and thermal characteristics that reflect IR rays into the greenhouse overnight. Closed curtains from heat dissipation through the presence of heat in the air as well as reducing the volume of air heated by the greenhouse cause energy saving in the heating system.

This system (Thermal Screen) reflects the sun’s heat rays, preventing them from reaching the plant and the greenhouse space, thus reducing the temperature. Also, by spreading this thermal curtain, especially at night, firstly, it prevents the incoming rays from entering the greenhouse space and secondly, it reduces the greenhouse space, which requires less air to be heated, thus saving energy and reducing current costs. It becomes a greenhouse. On the other hand, this type of greenhouse shade reduces moisture and diseases by preventing condensation drops on the leaves.

The raw materials of this type of greenhouse shed include strong PET yarn with a minimum amount of wrinkles plus aluminum tape. The energy storage curtain and canopy also have anti-UV additives to deal with harmful UV rays of the sun. These curtains are available in widths of 5.30, 4.80, 4.30, 3.25 meters, which are selected according to the structure.

Advantages of energy saving curtains:

• Reduce costs and energy required to cool the greenhouse by up to 50%
• Reduce the cost of purchasing heating systems and fuel consumption by up to 50%
• Better adjustment of air movement
• Proper distribution of sunlight resulting in uniform growth of plants
• Prevent temperature doubt from entering the plant
• Increase production by up to 30%
• Saving water consumption in main crops and facilities
• Reduce moisture by absorbing and evaporating it at the top of the curtain
• Greenhouse light control
• Reduce plant transpiration and condensate droplets (distilled) and thus reduce disease

 

Important practical points about these curtains

Spreading shading curtains that block a significant amount of sunlight and reduce photosynthesis, even in the hottest areas, should not be done all day and some months of the year. These curtains should be flat when there is too much solar energy.

– These curtains should be mechanized and movable so that morning and sunset light can be used.

– Curtains that are used for shading should be open so that the air can rotate to the extent that otherwise, the lack of air rotation will automatically increase the temperature.

– This curtain is used to store energy and canopies parallel to the ground and at the maximum possible height. The higher the height of the curtain installation site, the more air volume is controlled and as a result, the temperature control inside the greenhouse is improved.

– Aluminum curtain strips should be flat to receive all the sun’s rays and then reflect.

 

 Under what names is this system bought and sold in the market?

Greenhouse energy storage curtain is known by various names such as Saving energy curtain, aluminum mesh for energy storage, aluminum curtain, thermal curtain, thermoscreen curtain, thermoscreen screen.

Types of mechanization systems for energy storage curtains and canopies:

Exterior canopy system

• Anti-hail
• Only control the light and heat entering the greenhouse space

Internal shading system

• Light control
• Temperature control
• Humidity control

 

In any greenhouse shade system, one side of the curtain is usually fixed and the other side is movable. The mechanized system of the moving part moves back and forth, which offers its advantages to the greenhouse according to the type and application of the curtain.

This system is implemented in two ways:

• Cable system – gutter to gutter

In a cable system or tow wire system, the shade curtain or energy shade curtain opens and closes in the distance between the gutter to the gutter. In this system, the galvanized cable is connected to the moving part of the shed and the motor and gearbox can be installed at the end of the greenhouse or in the lateral part of the greenhouse at a lower height.

 

• Rack and pinion system – truss to truss

In the rack and pinion system, the shade curtain or energy saving curtain opens and closes at a distance of two or three arches of the greenhouse, 3-5 meters wide and perpendicular to the greenhouse opening.

The system uses a gearbox to move the rails, which are connected to metal pipes that form the main part of the system with the gearbox electromotor. This type of system is usually installed in the center of the greenhouse and at the height of the gutters.

 

Advantages and disadvantages of these systems:

– In the cable system, in summer, the space above the shed curtain is very hot, which reduces the effect of the cooling system of the fan and pad. This heat can be reduced by installing two exhaust fans at both ends of the greenhouse, which causes Costs increase.

– Parts of the cable system wear out sooner than the rack and pinion system.

– The cable system is easier to install than the rack and pinion system and at a lower height.

– In the cable system, the volume of air under the curtain that needs to be heated is minimized, but the volume of cold air above the curtain increases, and as a result, in the winter morning, when the curtain opens, the mixture of cold air above the curtain and warm air below the curtain to homogenize The hot air inside the greenhouse becomes harder.

– Shading of the cable system in the closed state is almost twice as much as the rack and pinion system.

– The rack and pinion system of the greenhouse is more accurate in general, which has a much more practical role in not wasting energy and optimizing fuel consumption.

– Light adjustment with rack and pinion system will be more accurate and easier, and as a result we will have better performance in product production.
