摘要:
A method for selecting between centralized and distributed maximum power point tracking in energy generating system is provided. The energy generating system includes a plurality of energy generating devices, each of which is coupled to a corresponding local converter. Each local converter includes a local controller for the corresponding energy generating device. The method includes determining whether the energy generating devices are operating under quasi-ideal conditions. The energy generating system is placed in a centralized maximum power point tracking (CMPPT) mode when the energy generating devices are operating under quasi-ideal conditions and is placed in a distributed maximum power point tracking (DMPPT) mode when the energy generating devices are not operating under quasi-ideal conditions.

The solar powered fan for a portable enclosure includes an electrical fan, which is pivotally mounted within the interior region of a portable edifice, such as that associated with a portable toilet facility. The pivotal mounting of the fan allows for selective user adjustment of the angular position of the fan with respect to the roof of the housing. Mounted on the roof, exterior to the enclosure, is a hollow housing having at least one solar panel mounted to an upper surface thereof. The solar panel charges a rechargeable battery received within the hollow housing which, in turn, is in electrical communication with the electrical fan.

A gas exchange apparatus is provided which provides for both passive fluid flow and blower associated fluid flow through a barometric valve. A battery powered blower is provided which allows for operation of the barometric valve during times when the barometric valve would otherwise be closed, and provides for enhanced volume of gas exchange.
摘要:
A solar power-operated cooling system installed in a motor vehicle for circulation of air, including a solar power device having a plurality of photovoltaic cells mounted for converting the radiant energy of sunlight into electric power and a power output terminal for output of electric power from the photovoltaic cells, an electric connector having an input terminal connected to the power output terminal of the solar power device and at least two output terminals, at least one blowing fan and at least one exhaust fan respectively installed in the interior door panel assemblies of the motor vehicle and electrically connected to the output terminals of the electric connector and driven to draw fresh air into or to draw hot air out of the motor vehicle.
摘要:
A vehicle vent (12) for exhausting air from a vehicle occupant compartment includes a float valve (32) that prevents water that enters an outlet (24) of the vent from passing into the vehicle through the vent inlet (20) but which has a drain passage (36) for permitting a limited flow of the water to a drain (38) on the vent inlet side of the float valve (32). The vent (12) preferably includes a fan (40) that is most preferably energized by a solar panel (48). Mounting of the vent (12) can be provided on the vehicle roof, on the roof just forward of a vehicle back window, or as part of a sunroof.
摘要:
There is provided in combination with a building roof over an air space requiring forced ventilation of solar energy heated air from the space through a vent hole in the roof, an electrically operated exhaust fan mounted in air exhausting relation on the roof and over the vent hole, and a solar panel for supplying electrical power to a fan driving motor when exposed to solar rays. Air exhaust passage through the device includes a backwash turbulence preventing ring-shape plate extending between a supporting ring body which is of smaller diameter than an exhaust air directing hood on which the solar panel is mounted, and a ring channel member supporting the exhaust fan in a manner to draw the exhaust air through the ring channel into the hood.
摘要:
An automobile air-conditioner wherein a direction of the sunlight coming into the passanger compartment of an automobile is detected, and if a deviated solar radiation is present, air-distribution is controlled to increase and decrease the quantity of air discharged from upper air outlets according to the detected solar radiating direction, while at the same time, louvers disposed in the respective air outlets are directed to an occupant to force conditioned air directly against the occupant. In the absence of the deviated solar radiation, the louvers are not directed to the occupant.
摘要:
A ventilator having a housing with first and second openings is mounted on structure of a vehicle and communicates directly with the vehicle cabin to move air between the vehicle cabin ad the outside environment. The ventilator may be nonportably secured onto the vehicle structure on the windows, panels or the roof and provides a sleek low profile unit having a powered impeller to positively move air between the external environment and the vehicle cabin which impeller may be powered by a self-contained power supply connected with a charging source such as a photovoltaic panel and/or the vehicle's own electrical system. The ventilator may also be portably mounted on a ventilator insert placed within a partially rolled down window or a sunroof to temporarily utilize the circulating effects of the ventilator.
摘要:
A vehicular internal fan ventilator, which includes a housing having set therein an internal ventilating chamber with a cross-flow air fan, a motor, a storage batteries and selector and a switch and a linkage to an oblique, external portion of housing which is fixedly mounted a solar cell board to collect solar energy for the motor and/or to charge the storage batteries. The housing comprises a top retainer rib and a bottom window glass channel for convenient installation in with a separate, flexible and cuttable packing strip in a car between door frame upper trim and window glass of a vehicle.

A solar energy collector for an automotive vehicle comprises an absorber panel and a cover panel spaced from one another to form an air flow channel. The passenger compartment of the vehicle communicates with the air flow channel via one or more openings, while the air flow channel communicates at a downstream side with the ambient atmosphere via one or more air outlets. The cover panel is made of a material transparent to incident solar radiation of optical frequencies and impervious to electromagnetic radiation of infrared frequencies. The absorber panel absorbs solar energy and transfers the heat energy so produced to air flowing through the air flow channel from the passenger compartment. The absorber panel is provided with support ribs on which the cover panel rests and with deflection ribs for deflecting the air stream and thereby enhancing heat transfer characteristics. The cover panel is advantageously connected to the absorber panel in a form lock fit which facilitates cleaning and maintenance of the absorber panel.
