Greenhouse ventilation systems based on thermal drives and renewable energy sources

This article describes the relevance of greenhouse ventilation, as well as the importance of greenhouse ventilation. Listed methods of greenhouse ventilation, methods of natural (manual and thermal) and mechanical (supply, exhaust, with a recirculation of direct and sequential) ventilation of greenhouses. Disclosed the relevance of the use of thermal drives in the natural ventilation of greenhouses, as well as the principle of the device thermal drives, listed the advantages of this method of greenhouse ventilation. The system of mechanical ventilation of greenhouses created by the authors on the basis of renewable energy sources, the advantages, as well as the wiring diagram of this system. The work of the system of mechanical ventilation of greenhouses based on renewable energy sources using solar panel, battery, battery charge controller, relay-regulator TRM-501 with thermocouple, and two fans of greenhouse ventilation is described. The question of using relay-regulators with thermocouples in the mechanical ventilation of greenhouses, as well as the advantages of using automated systems to control the greenhouse climate is revealed. Discusses the use and relevance of multiple sources of power, such as solar panel and centralized connection to the power supply network for mechanical ventilation of greenhouses. The conclusions on the above issues are summarized.
