Course/Module description:
Students will learn the basic principles of greenhouse microclimate management and control. Information on current greenhouse structures and crops grown in greenhouses will be provided. In the first part of the course the students will be introduced to principles of heat transfer, fluid mechanics and psychrometrics. The second part will deal with greenhouse heating, ventilation, cooling, shading, CO2 enrichment, sensors for climate control and basic control and management strategies.
Course/Module aims:
The course aims to provide students with a comprehensive understanding of greenhouse structures and their types, specifically focusing on those in Israel and globally. It will cover the essential processes involved in greenhouse climate management, exploring various systems and their operational mechanisms. Additionally, students will engage in basic calculations related to climate management and learn fundamental concepts in control processes to effectively manage greenhouse environments.
Learning outcomes - On successful completion of this module, students should be able to:
On successful completion of this module, students should be able to:
•define and characterize climate management processes and ways of dealing with problems in greenhouses. You will be able to move from a qualitative description of the problem to a quantitative solution. You will practice quantitative thinking. You will know how to define the systems needed for greenhouse climate management and perform basic calculations required in the design of the above systems.

Grading Scheme :
Additional information:
The Quiz is a protective grade.
At the end of the semester, each pair of students will be given a summary exercise sheet to be solved at home. The students will submit the solution and be tested on it orally. It may be that instead of a summary exercise there will be a written exam. Details will be given at the beginning of the semester.
