GREENHOUSES OF THE SECOND COMPLEX

Description of the solution and its benefits.
We have developed a system that allows you to make "thermos-greenhouses"
industrial sizes, that is, 100m long, 10m wide and 5m high.
Heat saving in a farm greenhouse made of film in winter is the main
problems to reduce production costs. Cucumber loves warmth, and
it is the technology developed by us that allows to increase thermal insulation
greenhouses twice, and three times to reduce the cost of production due to
increase yields and reduce fuel costs.
The principle of operation of the greenhouse-thermos pressurized.
Two layers of film are mounted on the frame (on the dome and both facades). inside, on
a snail is installed at the top of the facade - this is a special engine that
takes hot air from the top of the greenhouse dome and delivers it to
space between two layers of film using special
corrugated pipes. Flanges are attached to the inner layer of the film - they
allow you to fix the corrugated pipe on the film, while not tearing
inner film during operation. Hot air supply to
interfilm space is carried out periodically, with the help of
timer. To maintain the required pressure between film layers
the engine runs for 5-10 minutes, and the greenhouse is “blown away” for 15-20
minutes.
Thus, two layers of film with air between them hold heat better.
than glass greenhouses.
The frame of the greenhouse consists of arches, longitudinal runs and reinforcing
elements, which gives the structure reliability and absolute resistance to
any weather conditions. The reserve of rigidity is designed for operation
greenhouses under any gusts of wind and snow loads. frame
is installed by installing all the arches and facade legs on the heel
piles. Greenhouses are made of round and profile pipes. arches
greenhouses are made of a round pipe with a diameter of 40 mm with a thickness
walls 4 mm. A round pipe d 32 mm with a wall thickness of 2 is also used
mm, thick-walled round pipe (side ventilation). facade parts and
side ventilation greenhouses consist of round and shaped pipes
of various sections with a wall thickness of 2 mm. Frame cover -
special paint, allows you not to tint the frame throughout the entire period
film operation. Preventive work with the frame is carried out during
film replacement time - every 6 - 7 years.
A top ventilation system is mounted on the greenhouse, excluding
draft. In warm weather, raised transoms provide full
ventilation without losing the greenhouse effect for plants.
Tapestry system (the so-called "bows"). For tall garters we mount
tapestries. These are horizontal lintels inside the greenhouse through the arch on
height from the ground 2500 mm. Tapestries are used for gartering tall
plants, for fixing and hanging watering, lighting, etc. Also
trellis system is an additional reinforcing element
frame of the greenhouse, gives rigidity to the frame.
In the future, cables are laid on the trellises, to which they are tied
plants.
Film for the greenhouse. Film is mounted on supercharged greenhouses in two layers
French production under our order, 150 microns thick with a guarantee
10 years.
Fixing the film on the frame of the greenhouse. The film is attached to the frame with
using special profiles for greenhouse film. Fastening principle
films: a galvanized cassette is mounted on the pipe, in which
greenhouse film is inserted in two layers, galvanized is placed inside
spring. When changing the film, the flat spring is removed from the cassette,
then put back, while ensuring a secure fastening of the film.
The profile will last at least 20 years.
The main advantage is a more stable temperature in the greenhouse,
energy efficiency, no drafts.
The planned average yield is 3 tons of cucumber/tomato per week.
Guaranteed 1,5t in winter, 2t in summer
