| abstract |
The invention relates to a device for receiving solar energy, e.g. for air conditioning buildings with a preferably transparent wall (2), wherein preferably an outer transparent wall (2) and an inner wall (1) are provided, in addition to a cavity (4) which is disposed between the outer wall (2) and the inner wall (1) and through-which a heat transfer medium can flow. Optimum heat management control can be achieved by providing at least one thermotropic layer (4, 5) which controls heat take-up and which alternates according to the temperature thereof between a state wherein it is substantially opaque, i.e. absorbent, and another state wherein it is essentially transparent. |
