Description

Solar heat utilization module for targeted regulation of temperatures

Conventional [opal] thermal insulation materials on the outside walls of buildings protect the interior of buildings from low outside temperatures and, thanks to their insulating properties, delay the flow of heat from the inside to the outside, provided it is warmer inside than outside.

The solar heat radiation is hardly used in this case. As a result, so-called "transparent thermal insulation materials" [hereinafter referred to as TWD] were developed, which have the property of letting solar energy through. This heats up a wall behind the TWD, for example. This heat is transferred to the interior rooms [see: "New ways in building heating, passive solar energy use with transparent thermally insulated solar facades" by Andreas Wagner, Fraunhofer Institute for Solar Energy Systems, printed in the magazine "Luft- und Kältetechnik" issue 2/93, pages 73-77, Verlag Müller Karlsruhe}

The Fraunhofer Institute for Solar Energy Systems has built an energy self-sufficient solar house in Freiburg, in which TWD was used to a considerable extent [see above-mentioned article under: "Planning TWD buildings"3.

The sun provides the greatest amount of energy in summer. And it is precisely this high energy that is used in the TWD according to the latest scientific findings mentioned above.

wasted by shading the TWD [e.g. with blinds] to prevent overheating of the facades or the rooms behind the facade. Otherwise, it would be unbearable to be in the rooms because of the heat [see the above-mentioned article under "System components of the solar facade", paragraph and Figure 1].

This problem of not being able to use the energy that is most abundant in summer [due to overheating] is solved by the features listed in the protection claims.

The invention specified in the claims is intended to use the high energy generated in summer and at the same time prevent overheating of, for example, the walls [and thus the rooms] and, in addition, even make it possible to regulate the temperature of these rooms. With the appropriate design and construction of the storage unit - and appropriate control - the energy gained in summer can be used in winter.

The invention ensures that the high solar energy in summer can be used without overheating the rooms.

An example of implementation is explained using Figure 1.

From the outside (1) solar [radiation] energy (2) hits a body (5) which is filled with a medium (6) [e.g. liquid or gaseous]. This medium is heated up as a result. The heated medium is stored [e.g. by means of a control system in a separate storage tank or boiler]. From this storage tank, the medium is fed out as required, possibly by mixing with a

Medium of a different temperature] (9) is fed to the body (8) and gives it the required temperature to create the desired temperature in the room (13). It is important here that there is an opal thermal insulation (7) between the bodies (5) and (8), which prevents the body (8) from heating up due to the temperature of the body (5) and thereby causing the above-mentioned overheating. Without this opal insulation, the whole thing would no longer be controllable without high energy expenditure.

It is sensible if the energy (2) is passed through a TWD (4), which is also sensibly protected by a glass pane (3) to prevent it from becoming dirty, for example. The TWD (4) prevents the body (5) or the medium (6) inside it from cooling down.

It is also sensible to provide a wall (12) [with or without an air gap (10)] behind the body (8) - which can also be the supporting structure and can be made of concrete, brick or sand-lime brick, for example. This is then tempered by the body (8) so that the desired temperature is set in the room (13). In this way, the body (8) - with the appropriate design and construction of the storage unit and the appropriate control - can heat the room in winter and cool it in summer.

It should also be noted that it is also advisable to coat the body (5) and possibly the wall (12) on the outside with a black coat (9) in order to increase the absorption of energy.

Depending on the material [e.g. glass or plastic] the TWD is made of, it might be useful to provide an air gap (10) between the TWD (4) and the body (5) to protect the TWD from overheating so that it is not damaged.
