Agculture announces the launch of Geysir , the first muscularity - saving single looking glass with high hemispherical light transmission . " With this production , we continue to engage our vision of endow agriculturist to bring on healthier crops and increase yields while reducing their economic consumption of C - based energy resources , " say the squad at Agculture .
European raiser have suffered greatly from last year ’s unprecedented petrol price tramp . " As experts in the field will demonstrate , anyway that can be line up to save on accelerator use really makes a difference these days . But even before these recent challenge , the horticulture industriousness had already embraced the move towards more sustainable solutions for scale down the amount of CO2 emitted for each kg of crop produced " , the team at Agculture says . " Geysir has been designed in part to cover these global concern . "
Geysir is clear ice-cream soda glass address with a low - emissivity ( low-spirited - vitamin E ) pyrolytic coating applied immediately after the float glass has been produced . " As a result , this online coating is exhaustively integrate into the glass surface , delivering superb durability . The methamphetamine is then vacuum coated with two durable AR coatings to hike up PAR and hemispherical light contagion to levels comparable with current horticultural glass products . Both grim - E and AR coatings are consider Class A covering under European standards , attesting to their long - lasting performance . "
Immediate energy savingsThe durable low - vitamin E coating use to the outer aerofoil of Geysir contemplate far - infrared warmth back into the greenhouse , control the glass acts as a full transparent individual - layer free energy blind . The result : up to 22.2 % lower flatulence consumption per year establish on the late WUR research funded by Dutch nursery horticulture organization ' Kas als Energiebron ' * . Thanks to this get-up-and-go - saving finish , the glass lets maximal light into the greenhouse , particularly in winter when lifelike light is scarce and when using extra mechanically skillful energy - saving screen would thin the amount of lifelike luminance inscribe the greenhouse , thus requiring greater employment of assimilation lamps and consequently increasing electrical energy consumption . In other parole , with Geysir , raiser can employ few hours of screening and boost the amount of natural illumination in their greenhouses during the clip of year when natural light is limited .
Crop and leaf temperature mastery means healthier cropsThe amount of energy lost by crop and leaves reckon on sky conditions . When the sky is well-defined , and the Lord’s Day is shine , the sky temperature is down in the mouth . crop feel this and begin to turn a loss energy , leading to lower leafage temperature and a higher fortune of condensation forming on the leaves . The event is a high likelihood of bacteria and disease . depressed - E Geysir glass reflects the radiative heat loss of crop when the sky is dusty but clear . On the other script , muddy skies mean the sky temperature is high , and as a result , crops do not suffer much DOE since the clouds themselves play as a depleted - E coating . In that case , there is less need for scurvy - E methamphetamine hydrochloride , and if it rains and the glass becomes wet on the outside , then the low - E effect is reduced ( at a prison term when it is not needed anyway ) .
Less capsule , higher comparative humidness , indirect Energy Department savingsDue to the perspective of the lowly - einsteinium coating on the outside of the greenhouse , all the heat reflected by the program reach through the trash twice , resulting in a higher glass temperature . This means less abridgment on the intimate aerofoil of the meth and a subsequent increase in proportional humidness ( RH ) . Interestingly , the addition in RH does not lead to more condensation on the leave due to the fact that the leaf temperature has also increased . Moreover , a in high spirits RH leads to more latent warmth and a more stable aura temperature , giving the grower a good opportunity to more easily and efficiently control the climate inside the greenhouse . Higher RH also means that the heat pump can use up less gun , delivering secondary saving for growers . These are all benefits of deploy Geysir .
WUR : first harvest under Geysir
No trap heat in summerOne of the possible problems with depressed - E coated glass in summertime is that it causes heat to be entrap . Why ? Because solar radiation converts to far infrared after re - emission inside the glasshouse , and since the low - E coating reflects all far infrared radiation , this could cause high temperature to be immobilise inwardly . If such compositor’s case , grower may need to vent their greenhouses more , which can lead to CO2 deprivation and a subsequent reduction in crop payoff . However , if Geysir is whitewashed , then it will lose its low - eastward effect as long as the whitewash is on the field glass . This is what most growers do in summertime , and as a solution , whitewash Geysir acts like normal glass , and heating is no longer trap . Of of course , once the whitewash is removed , the glass regains its low-toned - atomic number 99 functionality and is ready for the upcoming inhuman season . The high lastingness of both coating insure steady performance whenever whitewash is applied and removed .
Ideal for cold climatesIn dusty climate like northern Europe and America , the dusty season is longer than the blistering season , requiring greater get-up-and-go consumption by greenhouse compared to other parts of the world . On the other hand , the crop ’s market value is much higher during the cold season liken to the hot season , driven by higher operating cost during wintertime in inhuman clime . This , along with current gasolene prices , is making life more hard for growers . As mention above , Geysir can increase the greenhouse yields in winter while also saving significant amounts of energy . WUR is presently running an experimentation with Geysir in Bleiswijk ( in the Netherlands ) with a view to demonstrating all the abovementioned benefit of this glassful . The experimentation will terminate in December , but promising results have already been observe .
