Solar energy-type ventilation apparatus for closed rooms, especially for greenhouses

摘要

An apparatus is described for the ventilation of closed rooms, especially greenhouses, comprising in combination one or more photovoltaic panels in parallel 2; one or more batteries in parallel 4; one or more ventilators in parallel 6; means 10 of detecting the temperature inside the room being ventilated, and a control unit 8, to which all of the aforesaid components are connected, which during the day actuates the ventilator(s) 6 in continuous fashion, causing the excess energy to accumulate in the battery (batteries) 4, and controls the turning on of the ventilator(s) 6 during the night if the internal temperature drops below a predetermined value. The apparatus is independent of the electrical power mains, it is activated automatically at various temperatures, it is modular and can be made with simple and long-lasting circuit components.
