How does it work ?
The corridor, located on the outer gable of the greenhouse, uses outside air for dehumidification and cooling. Thus, the corridor is used to mix inner air with external air. This phenomenon represents the air treatment of semi-closed greenhouses, mostly used for Venlo glass (Kubo, Van der Hoeven, Richel, CERTHON…) and plastic (CMF, Richel…) ones.
This system aims to :
-dehumidify the atmosphere of the greenhouse by renewing and drying out the air inside, due to outdoor air (during the night and in the morning)
-cool dry inner temperature with pad cooling system, on external side of the corridor
-reduce the amount of harmful insects, thanks to overpressure
-control the climate of the greenhouse avoiding the gap of temperatures
-optimize the use of energy and CO2
Heating system is composed of :
-air ducts below crops’ gutters for the diffusion of warm/cold air
-low temperature network (30-40°C) placed in vegetation
-high temperature network (70-80°C) placed on the ground to ensure heating
Cooling system could be composed of :
-pad and fan system using evaporative cooling
-fog system using evaporative cooling
