Abstract EN
The computational fluid dynamics technology is applied as the environmental control model, which can include the greenhouse space.
Basic environmental factors are set to be the control objects, the field information is achieved via the division of layers by height, and numerical characteristics of each layer are used to describe the field information.
Under the natural ventilation condition, real-time requirements, energy consumption, and distribution difference are selected as index functions.
The optimization algorithm of adaptive simulated annealing is used to obtain optimal control outputs.
A comparison with full-open ventilation shows that the whole index can be reduced at 44.21% and found that a certain mutual exclusiveness exists between the temperature and velocity field in the optimal course.
All the results indicate that the application of CFD model has great advantages to improve the control accuracy of greenhouse.
