Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in panel blocks used in translucent block panels such as glass block panels.

This type of block panel allows external light to come in from the wall surface, and at night, it can be expected to provide an effect of external lighting by transmitting internal light, and is also characterized by excellent sound insulation properties.

On the other hand, in recent years, it has become known that a solar collector is constructed using a wall surface as an energy-saving measure for hot water supply, space heating, and the like.

This invention aims to provide a panel block as a material that can also be used as a solar collector while taking advantage of the advantages of glass block panels and the like.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments. In the figure, reference numeral 1 denotes a light-transmitting hollow member made of glass or the like and having a substantially square cross section, and is shaped like an elongated tube. and,
The inside of this transparent hollow member 1 is divided at one diagonal position by a reflecting plate 2 made of, for example, an aluminum plate, and one side is configured as a solar collector chamber 3 and the other side as a lighting chamber 4. There is. The reflecting plate 2 has a selective absorption film 2a on the surface facing the solar collector chamber 3, and a reflective film 2b on the surface facing the lighting chamber 4.

As shown in FIG. 2, a plurality of panel blocks A having such a structure are fixed in a stacked state and constitute a wall surface as a block panel. In this case, a construction is incorporated in the construction of the block panel such that a heat medium such as water is supplied to the solar collector chamber 3 from one end of the hollow member 1 and taken out from the other end.

Therefore, as shown in Fig. 3a, such a panel block A, in addition to the heat insulation and sound insulation functions, also has the functions of receiving heat rays from the sun into the solar collector chamber 3 and warming the water. The heat collection function shown in Figure 3b and a part of the sunlight is reflected by the selective absorption film 2a and entered into the lighting room 4 as shown by the arrow in Figure 3c, and reflected by the reflective film 2b to introduce the light into the room. Lighting function occurs. Note that there is air in the lighting room 4, and this acts as a heat insulating layer. In addition, the selective absorption film 2a is provided on one surface of the reflection plate 2 to effectively achieve both the effect of absorbing thermal energy in the solar collector chamber 3 and the effect of letting light into the room via the lighting chamber 4. This is to achieve. It goes without saying that the reflecting plate 2 may be made of a highly heat-insulating material made of aluminum foil stacked in multiple layers with an air layer of about 1000 angstroms in between. Furthermore, optical fibers or the like may be arranged in all or some of the light-collecting chambers 4 of the hollow light-transmitting member 1 to introduce light from the outside, or an appropriate light source may be provided to serve as auxiliary illumination. In this case, auxiliary lighting can be used both indoors and outdoors.

As described in detail above, in this invention, a reflective plate is provided at one diagonal position of a translucent hollow member having a substantially square cross section to divide two chambers, and a heat transfer liquid is placed in one of the chambers. Therefore, in addition to the heat insulation, sound insulation, and lighting effects of conventional block panels, it can also function as a solar collector.
