Control of solar air systems in agriculture


, : Control of solar air systems in agriculture. Computer applications in agricultural environments Proceedings of the 42nd Nottingham Easter School, 1986: 95-114

The dynamic behaviour of solar air systems is discussed in order to demonstrate their potential for control by microcomputers. Configurations and components in typical solar air heating systems are described; the bidirectional and unidirectional rock pile systems are explained. Experimental results are examined for both systems in greenhouse heating. Ten operational modes were controlled in the bidirectional rock pile system with reliable and effective performance.
