System and method for determining an environmental parameter distribution

A system for determining a distribution in a greenhouse of values of an environmental parameter, the system comprising

• one or more air flow sensors for determining a magnitude and/or direction of air flow at first one or more positions in a first region of the greenhouse, and
• one or more environmental sensors for measuring the values of the environmental parameter at second one or more positions in the first region of the greenhouse,
• at least one actuator configured to influence the distribution in the first region of the greenhouse of values of the environmental parameter, and
• a data processing system that is configured to
• receive first signals from the one or more air flow sensors, the first signals being indicative of the respective magnitudes and/or directions of air flow at the respective first one or more positions in the first region of the greenhouse, and
• receive second signals from the one or more environmental sensors, the second signals being indicative of the respective values of the environmental parameter at the respective second one or more positions in the first region of the greenhouse,
• assigning the magnitudes and/or directions of air flow at each of the first one or more positions in the first region of the greenhouse and the values of the environmental parameter at the second one or more positions in the first region of the greenhouse as boundary conditions for a fluid mechanics model,
• applying the fluid mechanics model to determine, based on the the boundary conditions, values of the environmental parameter at third one or more positions in the first region of the greenhouse thus determining the distribution in the first region of the greenhouse of values of the environmental parameter, wherein the third one or more positions are different from the second one or more positions,
• determining a first action that would cause a change to at least one of the boundary conditions and to the distribution in the first region of the greenhouse of values of the environmental parameter, and
• operate the at least one actuator in accordance with the first action causing a change to the distribution in the first region of the greenhouse of values of the environmental parameter based on the distribution in the first region of the greenhouse of values of the environmental parameter determined,
• wherein the at least one actuator comprises at least one of:
• a) an actuator configured to cause window blinds to go up;
• b) an actuator configured to cause window blinds to go down;
• c) an actuator configured to cause a window to open;
• d) an actuator configured to cause a window to close;
• e) an actuator configured to cause a window to substantially block light from outside;
• f) an actuator configured to cause a window to substantially allow light from outside;
• g) an actuator configured to increase a rate of heat provisioning of a heat source;
• h) an actuator configured to decrease a rate of heat provisioning of a heat source;
• i) an actuator configured to increase a rate of carbon dioxide provisioning of a carbon dioxide source;
• and
• j) an actuator configured to decrease a rate of carbon dioxide provisioning of a carbon dioxide source.
