Abstract:
There is provided a solar heater system comprising: a plurality of open ended parallel air heating tubes; and upper and lower manifolds operably coupling respective ends of the air heating tubes and wherein the system is useable in an air heating mode of operation wherein air flows via the lower manifold for heating within the air heating tubes and via the upper manifold into a building space for heating. The system may also comprise an excessive hot air dissipation mechanism and wherein the system is usable in a non-heating mode of operation wherein excessive hot air is dissipated from the dissipation mechanism to the atmosphere.
Abstract:
The invention relates to a system for using solar energy to ventilate a space, particularly the interior of a building, although other structures may also be ventilated such as crop stores, desalination plants, glass houses and power generation plants. The system can operate in different modes so that solar energy is used to heat or cool the space, as required. Part of the system is a solar heat collector, which absorbs available solar energy. The solar heat collector includes two separate channels able to receive air from different sources and pass them in counter flow. The channels transfer heat between them using an efficient turbulence-inducing structure that enables the system to operate in the different modes to heat or cool a space.

Abstract:
Der Erfindung liegt daher die Aufgabe zu Grunde, einen gattungsgemäßen Sonnenkollektor zur Erwärmung von Luft zu entwickeln, der einen großflächigen Wärmetausch ermöglicht und dabei einen höheren Wärmetauschkoeffizienten besitzt. Dazu wird vorgeschlagen, dass im unteren Luftraum (27) zwischen dem Lufteintritt (18) und dem Luftaustritt (19) Strömungswiderstände vorhanden sind, die den Luftstrom über die Breite der Absorberplatte (25) verteilen und verwirbeln.
Abstract:
This invention relates to a fluid heating system, wherein the fluid is capable of being heated by means of solar energy, the fluid heating system including: - an outer housing; - an inner housing contained within the outer housing and including an absorbent material core located within the inner housing to define a flow passage between it and the walls of the inner housing; the absorbent material core being suitable for absorbing solar energy transmitted through the outer and inner housings; and - wherein the outer housing; inner housing; and the absorbent material core are arranged such that solar energy is transferred through the fluid in the flow passage before being absorbed by the absorbent material core.
Abstract:
The present invention relates to a light absorbing device (1 ) which comprises an transparent outer material layer (2), a space (5) through which air is circulated and heated by light radiation passing through the outer the material layer (2), a radiation absorbing material layer (4), and an element (6) which is adapted to divide the space (5) in at least a first subspace (9), which comprises a first opening (12), and a second subspace (10), which comprises a second opening (13). The air is adapted to flow along a path having an extension from the first opening (12) to the second opening (13). The path comprises flow resistance reducing means in at least one portion (9a, b, 10a, b) of the space (5) which is adapted to reduce the flow resistance for the gaseous medium when it is guided through said portion (9a, b, 10a, b) of the space (5).
Abstract:
Solar collector (1) comprising: a first plate (2) for collecting solar energy, a second plate (3) wherein there is an intermediate space between the two plates, and a quantity of liquid which is present between the plates (2,3) for absorbing the energy collected by the first plate (2). A framework (4,7) for fixing the plates (2,3) at a mutual distance along the edges thereof so as to seal the space between the plates (2,3) and to create space between the plates which comprises the liquid.
Abstract:
A solar collector including a heat-insulated vessel (10) and an absorber (50). One side of the vessel is a transparent cover (20) turned towards the sun and consisting of a hollow element with parallel outer (30) and inner (32) walls between which air to be heated is at first forced to flow in order to collect, through convection, the heat energy absorbed by the cover and coming from both the direct solar radiation and the radiation of the absorber (50). The air thus preheated is then forced to flow over both sides of the absorber (50) in order to recover most of the stored heat energy. Said collector, when made self-contained by means of phovoltaic cells, is particularly useful for heating and ventilating homes.
