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:
To provide a comprehensive understanding of basic processes in greenhouse microclimate management. To practice quantitative analysis of problems associated with greenhouse microclimate.
Learning outcomes - On successful completion of this module, students should be able to:
