A smoke test was recently carried out at HortiTech in the greenhouse where Alcomij is testing their special Caeli greenhouse fans.
The Caeli™ fans are used to homogenize and dehumidify the greenhouse climate according to the principles of new growing. They feature proportionally controllable ventilation and damper positions, allowing air to be drawn in from below and/or above the screen. Sensors measure temperature and humidity above and below the screen, after which an algorithm calculates the desired flap position and ventilation capacity of the individual units every 10 minutes. A Cloud platform makes climate differences quickly visible via graphs and heatmaps, and its link to the climate computer makes it easy to operate.
Graphs (see below) show that temperature and humidity differences in various greenhouse compartments become significantly smaller once Caeli is active. This means more control over the climate and good conditions for the crop.
Top graph: temperature. Lower graph: humidity. The grey area indicates when Caeli is active. Click here to enlarge the graph.
As a developer, Alcomij plays an essential role in the innovation and further development of Caeli.
The trial at HortiTech in Honselersdijk can still be visited. The first tomatoes will be harvested this week.
A video of the smoke trial can be seen below.
