Fan placement is incredibly important in a greenhouse. You need to think about the orientation and the distance between the fans, otherwise vertices may occur in one area, whereas stagnant air occurs in other areas. Stagnant air is very disadvantageous because it causes reduced crop growth and increases the chance for plant diseases and mould.
Information needed to determine the optimal greenhouse fan placement is for example:
- Greenhouse area
- Greenhouse volume
- Crop type
- Outside climate
- Inside climate
- Corridor positions
- Power supply locations
It is important to think of both horizontal air circulation as well as vertical air circulation when furnishing a greenhouse.
Circulation fans hanging in the top of the greenhouse will provide horizontal air circulation as they will spread the air evenly across the entire greenhouse area, resulting in a homogeneous temperature distribution for all plants. It also spreads the introduced fresh air around the whole greenhouse, giving all plants the same CO and CO2 levels. Air distribution hoses or air ducts as well as strategically placed fresh air intakes, help with vertical air circulation. This evens out temperature differences even further, but is especially beneficial to optimizing humidity levels.
Moisture build-up and plant deterioration are avoided when air circulation and air distribution are executed well.
At Enerdes we can help you achieve this and we will design the most optimal air distribution and air circulation system for you. Getting the best air flow to all plants while keeping energy consumption to a minimum is our main goal!
