Description of the solution and its benefits.
We have developed a system to make “thermos greenhouses”
industrial size, i.e. 100 meters long, 10 wide and 5 high.
Heat conservation in a farm greenhouse made of foil in winter time is the main
problems to reduce the cost of production. The cucumber likes warmth, and
it is the technology we have developed that makes it possible to increase thermal insulation
greenhouse by two times, and by three times reduce the cost of production by
to increase yields and reduce fuel costs.
Principle of operation of a supercharged greenhouse-thermos.
Two layers of film are mounted on the frame (on the dome and both facades). Inside, on the
a snail is installed at the top of the façade, which is a special motor which
takes the hot air from the top of the greenhouse dome and delivers it to the
the space between the two layers of film with the help of special
corrugated tubing. The flanges are attached to the inner layer of the foil – they are
allow the corrugated pipe to be attached to the foil without tearing
the inner film in the process. Hot air supply to
interfilm space is carried out periodically, with the help of
timer. To maintain the correct pressure between the film layers
the engine runs for 5 – 10 minutes and the greenhouse “blows down” within 15 – 20 minutes
This way, two layers of film with air in between hold heat better
than glass greenhouses.
The frame of the greenhouse consists of arches, longitudinal purlins and reinforcements
elements, which gives the structure reliability and absolute resistance to the
in all weather conditions. The stiffness reserve is designed for operation
the greenhouse under all wind gusts and snow loads. Frame
is installed by mounting all arches and front feet on heel feet
piles. Greenhouses are made of round and profile pipe. Arches
greenhouses are made of round pipe with a diameter of 40 mm and a thickness of 40 mm.
4 millimeter walls. Round pipe d 32 mm with wall thickness 2
mm, thick-walled round pipe (side ventilation). Facades and
side ventilation of the greenhouse consists of round and profile pipes
of various cross-sections with a wall thickness of 2 mm. Coating the frame is.
special paint, allows not to paint the frame during the whole period of time
of the film’s operation. Preventive work on the frame is carried out in the
time of film replacement – every 6 – 7 years.
An overhead ventilation system is installed on the greenhouse, which excludes
draught. In warm weather, the raised transom windows provide a complete
ventilation without losing the greenhouse effect for the plants.
The trellis system (so-called “bows”). For tying taller plants we mount
trellises. These are horizontal lintels inside the greenhouse through the arch on the
height from the ground 2500 mm. Trellises are used to girdle high-growing plants
plants, for fixing and hanging watering, lighting, etc. Likewise.
the trellis system is an additional reinforcing element
of the greenhouse frame, gives rigidity to the frame.
Later, cables are laid on the trellises, to which the ropes are tied
Greenhouse film. Two layers of film are mounted on the supercharged greenhouses
French made to our order, 150 microns thick with guarantee
10 years.
Fixing the film on the frame of the greenhouse. The film is attached to the frame with a
with special profiles for greenhouse film. Fixing principle
film: a galvanized cassette is mounted on the pipe, in which the
two layers of greenhouse foil, galvanized galvanized foil inside
spring. When changing the film, the flat spring is removed from the cassette,
is then put back in place, while ensuring that the film is securely fastened.
The profile will last at least 20 years.
The main advantage is a more stable temperature across the greenhouse,
energy efficiency, no draughts.
The planned average yield is 3t of cucumber/tomato per week.
Guaranteed 1.5t in winter, 2t in summer
