Abstract
It is disclosed a ventilator (9A, 9) comprises a housing (20) having opposite first (21) and second ends (22) and an axial rotor (23) arranged in a ventilator flow path (23A), wherein the ventilator flow path (23A) has an inlet at the first end (21) of the housing (20) and an outlet (22A) at the second end of the housing (20) and wherein an additional flow path (25) is present comprising one or more sensors and which additional flow path (25) fluidly connects an opening (16, 24) in the housing (20) with the ventilator flow path (23A) for drawing in air due to a venturi effect via the additional flow path (25) towards the ventilator flow path (23A), wherein the sensors are temperature and/or humidity sensors.
Claims21
A ventilator comprising 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-.
A method to control the climate in a greenhouse interior space comprising an upper space positioned above a lower space by
- (i) measuring the local temperature and/or local humidity at numerous different local positions in the lower space resulting in numerous local measured temperature and/or humidity values,
- (ii) displacing air from the upper space to the lower space wherein the volume of air which is displaced at one local position is based on the measured temperature value and/or a measured humidity value at said local position.
