Figures and feedback
On average, an AVS can remove 10 g/h/m2 of moisture per m3/m2 of ventilation air, based on a greenhouse temperature of 20°C with a RH of 90% and average outdoor conditions. This rises to around 12 g of moisture /h/m2 at a greenhouse temperature of 22°C and 90% RH.
These values can be read in a Mollier or h-x diagram.
