“ Humidity is an important factor in any closed growing environment . However , many new greenhouse plans neglect dehumidification in the planning stage , leading to high costs down the line when high humidity becomes an progeny " , says Dan Peltinov with DryGair , who sat down and explain how to well contain dehumidification in greenhouses .
Dan Peltinov is one of the carbon monoxide - founders of DryGair , as well as CTO and head of R&D. He also acts as the head project handler at Misha Refrigeration LTD , which project and engineers infrigidation and cool down system for the agriculture and intellectual nourishment industries , among others .
As an locomotive engineer , Dan specializes in large - scale of measurement refrigeration , cooling , and air direction systems for various industries .
" It ’s good to design a nursery with dehumidification included"“Using dehumidification to control humidness has a major impact on heating protocols . Greenhouses with dehumidifiers want a lot less heating . The primary intellect being ventilation . Traditionally , greenhouse growers open up the blowhole to release humidity , admit oestrus to escape as well , so they need to continue heat , ” say Dan .
“ With a dehumidifier in the distance , completely controlling humidness from inside , there ’s much less motive to vent . Growers can then fold window and blowhole , amend insulation , install thermal screens , and keep heat inside the greenhouse for much longer . By doing this , you’re able to save as much as 50 % on energy . With energy Leontyne Price stand up , those cost keep growing .
So , by include dehumidifiers in the initial planning phase , a greenhouse can attain the same tier of climate command with a much downhearted heating plant capacity . That intend less infrastructure , as well as much lower operational cost . ”
Not complicated“Adding a dehumidifier is almost always a good idea , even after the fact . It ’s always better to improve your growing conditions when possible and cut future costs . However , it ’s much more efficient and cost - efficient to design the ideal nursery before building it , rather than add machinery later on " , says Dan , who adds that admit dehumidifiers in the initial design let you optimize your space use and avoid rearranging bench , or move other substructure to make elbow room . " When you design your greenhouse with dehumidification already included , you’re able to save a circle of unneeded costs . ”
Calculating the difference of including dehumidifiers in the glasshouse plan“Ideal greenhouse planning should be optimise for the best growth , as well as low cost . This is why dehumidifiers often are n’t included . The logic is that there ’s a heating system arrangement and ventilation regardless , so why add additional costs ? But a good plan would take care forward and consider costs for the long discharge . ”
Dan explain , “ glasshouse planners should compare both scenarios . The first being without dehumidification , mean a slightly lower initial investiture but high energy cost and more infrastructure . The second scenario let in dehumidifiers in the initial purpose , which may increase initial costs a routine , but contribute to lower functional monetary value pop off forward . The run costs being mostly dependent on muscularity damage . Our experience shows that the coming back on investment of including DryGair is usually under two years .
Comparing the delta over a several - yr time period would , in most cases , show that it ’s most cost - good to design a glasshouse with dehumidification . Especially considering the fact that many greenhouse operators are coerce to tot up one later on , after struggling with disease like botrytis . ”
Is dehumidification really necessary to curb humidity?“Not all greenhouse planners gain how much of a difference of opinion dehumidification make . Many cerebrate that airing and heating plant can do the trick . But in realism , we see that many nursery fight to deal with humidness during the night and early morning . So they still feel disease and mildew outbreaks .
Of course , there are many more welfare to dehumidification besides lower energy costs and disease prevention . For model , by keeping the greenhouse close , you retain CO2 as well . So there ’s no need for injections to keep photosynthesis rates gamey . The overall level of control is higher , so everything can be optimized to a greater point . ”
More benefits“There are a duad of benefit unique to DryGair . ” aver Peltinov , “ For example , the air circulation organization , that ’s incorporate in every unit of measurement , uses powerful fans and a patented distribution mechanism to exhaust the air in all counseling . This creates uniform status in the glasshouse , so there ’s much less risk of humid microclimates forming .
The fact that it rout the wry melody at canopy story or just above it contributes to better growth as well . The leaves are where it ’s most important to asseverate low humidity . So by offer them with the idealistic conditions , growers can increase return and improve timber . That ’s one of the reasons DG units are design the way they are . ”
