Utilization of natural resources for a garden greenhouse
Šplíchal, Jan ; Babička Fialová, Dominika (referee) ; Jegla, Zdeněk (advisor)
The thesis performs the analysis of the potential of using natural resources, specifically solar radiation and rainwater, for garden greenhouses of various sizes, using self-created balance calculation tools and calculations made by them using available meteorological data. At the same time, the thesis provides a comprehensive overview of the technological possibilities of photovoltaic and irrigation systems in the context of garden greenhouses. The results of the calculations show that appropriately designed technological solutions can effectively ensure sufficient electricity and water for the autonomous function of the system. For smaller greenhouses, a simple photovoltaic system with one panel of about 0.5 m2 and a battery with a capacity of 300 Wh is sufficient for normal seasonal operation. For medium-sized and larger greenhouses, it is necessary to consider the optimal number of panels and batteries with regard to operational needs and the length of the season, but the number of panels and batteries is also acceptable in this case. For the irrigation system, it is important to consider the capacity of the barrel, which should be proportionate to the way the water is used. If the primary use of drip irrigation is being considered, then the performed analyzes show that a barrel capacity of 100 liters should be sufficient even for the needs of larger greenhouses.
