The mood changes that have occurred in recent year demand new and technologically update tools also in the protect crop sphere . Lirsa watering place ( an Arrigoni radical company ) launch a research project in 2021 for the growth of an advanced natural covering motion-picture show capable of balancing both daytime temperatures ( heat decrease ) and nighttime - clip temperature ( slacken down heat passing ) with an automatonlike mechanics derived from the use of functional nano technologies .
" Thanks to Lirsa ’s R&D , it is finally possible to fight rising temperatures with a greenhouse blanket that can boil down caloric zip ( NIR ) entering the greenhouse without reducing the entire idle transmission , which is useful and necessary for PAR ( photosynthetic activity radiotherapy ) " , portion out Luigi Pezzon with Arrigoni .
" With V - Agro Air Cool by Lirsa health club it is now potential to reduce the heating system inside the greenhouse without shading system , but only and exclusively with plastic cinema insure . "
The daytime temperature is determined by the stimulus of the NIR ( 780 -2500 nm ) while the average / long IR radiation therapy ( over 2500 nm ) which accumulates in the soil during the day ( which therefore heats up ) is released during the night time .
abbreviate daytime temperatures , especially during the summer month , prevent :
- Water waste.- Reduction and block of sprouting due to high temperatures- The flop of craw productivityAt the same time , slowing down heat loss during the night , in add-on to reducing energy cost , avoids crops thermal focus .
V - Agro Air Cool film was consider as an option both to the use of surface paint on glasshouse roofs to reduce daytime temperature and to interference pigments , mineral fillers and spheres of various kinds which , when added during the extrusion of the flick , have the side effect of lowering all the spectrum solar radiation syndrome , include the PAR .
Simulated tests of solar might simplification passing through the V - AGRO AIR COOL celluloid were verified using a Lux Meter ( W / m2 ) . These measurements confirmed the rigour of the idea formthe beginning , because they showed solar power radius values reduced almost four times ( in % ) than a 200 micron boneheaded LDPE film without additive ( average solar force detected : 890 W / m2 - natural LDPE film absorption 8.10 % - V - Agro Air Cool film absorption 30.80 % )
On the basis of the above , V - Agro Air Cool picture show was installed in different geographic areas of the Mediterranean area and the greenhouses were monitored in unlike climatic conditions between twenty-four hour period and Nox , in the various seasons during the various stages of cultivation .
" The data point obtained confirm that the thermic equalizer of the V - Agro Air Cool picture show has reduced ( equate to normal and traditional greenhouses precondition ) daytime temperatures by up to 5 ° C / 7 ° blow in the summertime periods with an middling urine saving of over 16 % and up to peaks of over 10 ° C more in some minute of the night in the wintertime period , with consequent patent improvements in qualitative / quantitative agronomic yield .
