The system uses at least one primary fan for maintenance of an excess pressure between the walls of the building. A secondary fan (6) is located in a separate room (2) connected to the greenhouse. - Air from the greenhouse is sucked into the room, and, as required, is tempered and dehumidified, after which at a possibly reduced rate, is re-distributed into the greenhouse. Thus in relation to the ruling ambient air pressure higher pressure is maintained in the space between the greenhouse walls, and lower pressure is maintained inside the greenhouse itself.(2) |
