How to work with +Active Air in a (semi) closed greenhouse?

 Answer 




The climate settings:


The standard settings ventilation temperature leeside and windside are set to 35 °C and are hidden.
Cooling 1 can be a pad wall and cooling 2 can be a fogging system.

The following situations can be released:
  • Recirculation: closed pad wall valve; recirculation of greenhouse air via the air treatment corridor by using the fans

    in semi closed greenhouses recirculation is always released.

  • Ventilation: open pad wall valve; mix outside air and greenhouse air in the air treatment corridor

    |n the example above the ventilation is released when the greenhouse temperature is higher than 20,5 (= 20 + 0,5) and not released when the greenhouse temperature is lower than 19,5 (= 20 - 0,5).

  • Dehumidification; open pad wall valve; dehumidify via overpressure window

    The setpoint RH is 75%. When the measured RH is higher than 80% (= 75 + 5) then the dehumidification is released.

  • Cooling; make pad wall wet; mix outside air and greenhouse air in the air treatment corridor

    Active Air cooling is released when the cooling program is active.

iSii +Active Air can consist of the following controls:
