Greenhouse comprising a climate control system

A greenhouse comprising a climate control system and a roof, walls and a floor defining an interior greenhouse space, said greenhouse space comprising an upper space and a lower space below the upper space:

• wherein the roof is provided with closable openings;
• wherein the climate control system comprises a grid of control units and a central controller;
• wherein a control unit comprises an air flow path from the upper space to the lower space, an in air displacement controllable ventilator for displacement of air from the upper space to the lower space via the air flow path and present in the lower space of the greenhouse and wherein the temperature sensor and/or a humidity sensor are suited to provide a measured temperature value and/or a measured humidity value;
• wherein the central controller is programmed to individually adapt the air displacement of the ventilator of each control unit based on the measured temperature values and/or a measured humidity values;
• wherein the ventilator comprises a housing having opposite first and second ends and an axial rotor arranged in a ventilator flow path, wherein the ventilator flow path has an inlet at the first end of the housing and an outlet at the second end of the housing and wherein an additional flow path is present comprising one or more temperature and/or humidity sensors and which additional flow path fluidly connects an opening in the housing with the ventilator flow path for drawing in air due to a venturi effect via the additional flow path towards the ventilator flow path;
• and
• wherein the roof is a saddle roof or arched roof wherein the roof is supported by trusses and wherein the trusses are supported by hollow columns having a hollow internal space and wherein one or more removable screens are present between the trusses, whereby the removable screens divide the interior greenhouse space into the upper and the lower space.
