A heat collector comprises a transparent glazing (12) exposed to the ambient. The transparent glazing (12) is spaced from a back surface to define a plenum (16) therewith. A plurality of perforations is defined through the transparent glazing (12) for allowing outside air to flow through the transparent glazing (12) into the plenum (16) and substantially maintain the transparent glazing (12) at the ambient temperature, thereby providing for higher thermal efficiency.

A solar receiver includes: water jacket panels each having a light-receiving side and a back side with a watertight sealed plenum defined in-between; light apertures passing through the watertight sealed plenums to receive light from the light-receiving sides of the water jacket panels; a heat transfer medium gap defined between the back sides of the water jacket panels and a cylindrical back plate; and light channeling tubes optically coupled with the light apertures and extending into the heat transfer medium gap. In some embodiments ends of the light apertures at the light receiving side of the water jacket panel are welded together to define at least a portion of the light-receiving side. A cylindrical solar receiver may be constructed using a plurality of such water jacket panels arranged with their light-receiving sides facing outward.

A bio-inspired window can be created by applying one or more heat exchange layers to one or more surfaces of a window of a building, boat, vehicle or any other structure. The heat exchange layer can include an interconnected network or array of channels or microchannels that can be used to flow a fluid over the surface of the window. The fluid can be used to heat or cool the surface of the window panel to control the flow of heat across the window and reduce the heating or cooling energy load of building. The fluid can be heated or cooled using the ambient air in the building. The refractive index of the fluid can be adjusted to change of optical transparency properties of the window. In some embodiments, the window can appear nearly as clear as an ordinary panel of glass. In other embodiments, the window can color, block or scatter the incoming light.

Various embodiments of a fluid displacement system are disclosed. The system may include a reservoir containing a fluid in a liquid state and a first chamber hydraulically connected to the reservoir to receive the fluid from the reservoir. The first chamber may be configured to receive solar energy and configured to convert the received solar energy to vaporize the fluid. The system may also include a second chamber hydraulically connected to the first chamber to receive the vaporized fluid from the first chamber. The second chamber may be configured to condense the vaporized fluid, causing depressurization in the second chamber. The system may also include a hydraulic connection between the second chamber and a source of fluid to be displaced. The system may be configured such that the depressurization of the second chamber may cause fluid in the source of fluid to be displaced through the hydraulic connection.

A solar heat exchange panel that includes a lower plate and an upper plate that together define an interior volume containing a flowing heat transfer fluid. The upper plate includes a plurality of upward extensions and downward extensions that cover the top surface of the solar heat transfer panel and are configured to capture solar radiant energy. The lower plate plate includes a plurality of upwardly extending hollow lower plate extensions. The lower plate extensions are aligned with the bottom portions of each upward extension of the upper plate and almost touching. Each of the downward extensions form the upper plate extend down and are joined to the base of the lower plate. In operation, a heat transfer fluid introduced into an inlet on one end of the solar heat transfer panel passes through the defined interior volume and is intimately contacted with the solar heated surfaces extending down into the solar heat transfer panel from the upper plate. A substantially infrared transparent plate across the top surface of the solar heat transfer panel creates a top interior space that encloses a path of flowing air which is simultaneously heated along with the enclosed heat transfer fluid in the lower interior space.

摘要:
A solar cell module (206,404) is provided at the position of a heat collecting plate (405) inside a heat collector (200,400), at the position of its window member (204,403) or at the position of its bottom plate. With such constitution, a hybrid system can be achieved in which the hot air can be led into a house while maintaining the performance of solar cells making use of amorphous silicon semiconductors. In the case where solar cells are provided at the position of the heat collecting plate, a resin used as a filler has so high a thermal resistance that the heat conduction to the air may be insufficient to make it impossible to obtain hot air having a sufficiently high temperature. To solve this problem, the solar cell module (206,404) is made to have a smaller thermal resistance on the non-light-receiving side than the thermal resistance on the light-receiving side.
摘要:
Our invention consists of two separate and discrete families of polymers, e.g. thermosetting Fiberglass Reinforced Plastics (“FRP”) and thermoplastics. Both are used as the materials of construction to fabricate solar thermal collectors. These families have the same general configuration and are based upon the same principles. Both families are used in a form that some of the walls of the collector are translucent. Both families incorporate a passage through which the thermal fluid flows. Both families make use of dyes to absorb energy from the sun in the fluid and the collector walls. Each of the families makes use of improved collector configurations and designs and special operating approaches. Each family can serve different markets for different solar thermal collectors. In particular, FRP stands alone as an emerging new category of materials for a broad range of applications including everything from novel solar thermal collectors to exotic airplanes.

The invention relates to a panel-based solar receiver for a thermal solar tower power plant (4), which comprises: a front panel (8), the external surface of which receives solar radiation (2) from the field of heliostats (3), a back panel (9), sealing elements (10) between the panels (8, 9), arranged at the lateral ends of both, an intake collector (5), located in the upper part of the panels (8, 9), where the heat transfer fluid enters the receiver (1) and an evacuation collector (6), located in the lower part of the panels (8, 9), where the heat transfer fluid leaves the receiver (1); wherein the front panel (8), back panel (9) and the two sealing elements (10) form the receiver body (16), which constitutes a passage for the heat transfer fluid (7) to travel through. Each solar tower can contain one or several panel-based receivers (1) and be arranged in series or in parallel, with the same or a different fluid (7) circulating there through.
摘要:
A device for heating supply air for the ventilation of a room, which is supplied with supply air from a glazed balcony located adjacent to the room, has an outer balcony parapet (5), which is permeable to the heat radiation of the sun, and a heat-absorbing inner balcony parapet (12) located inside the outer balcony parapet (5) and adapted to be heated by the solar heat radiation that penetrates the outer parapet. The outer and inner balcony parapets (5, 12) define between them a substantially vertical air gap (13). A fan arrangement (16) is adapted to force air present in the glazed balcony through the air gap (13) from the lower part thereof to the upper part thereof for heating of said air. Inner outlets (19) are arranged in the upper part of the air gap (13), through which outlets the heated air is allowed to flow out into the glazed balcony before being supplied to the room as supply air.
