に戻る。[Function] The blades are arranged in parallel in horizontal and vertical directions, and their inclination angles are changed to block direct sunlight. Furthermore, in times such as summer and winter when heating and cooling are required, hot and cold water is supplied and circulated through the heat conductor so as to eliminate the difference between the outside temperature and the indoor temperature. As a result, in winter, the temperature of the blades increases to block the influence of outside temperature, and in summer, the temperature of the blades decreases, blocking the influence of outside temperature. The temperature of the blinds offsets the cold radiation from the outside temperature. The heat conductor attached to the blade supports the blade with a support pipe through which cold and hot water passes, and is further installed in the support pipe between the water supply pipe and the return pipe. Transfers the heat of the cold and hot water in the water supply pipes to. For blinds, the angle of inclination of the blades can be changed so that the outside scenery can be seen. Especially in the middle of the season, solar radiation is not much of a problem, so the connecting part between the support tube and the blade is made of a mating structure, and the support tube is connected to the blade. Make it a rotation axis. Adjust the inclination angle of the blade around this axis using a string. The angle of inclination of the blade is changed by the amount of tension on the string, and the blade rotates and tilts around the support tube. The amount of tension on the string is automatically determined by the amount of expansion and contraction of the elastic body. If the heat radiation from sunlight is strong, the temperature of the expandable body will rise and its length will change, and this change will cause the blades to change to an angle parallel to the plane of the window. When the outside temperature drops, the expandable body returns to its original length and the blade's angle of inclination also returns to its original length.

１３は上に配置する。FIG. 2 shows an embodiment of the blind 5. 4A is a front view of the blind 5, and FIG. 1B is a view taken along the line B-B of FIG. That is, FIG. 2(B) shows a cross section of the blade 9 and will be described. This blind 5 has horizontally long blades 9 arranged in parallel in the vertical direction, and both ends of which are rotatably supported. At the left end of the blade 9, the water supply pipe 1
1 is piped vertically, and the return pipe 13 is connected to the water supply pipe 11 at the right end.
The piping is run parallel to the A support pipe 15 is provided between the water supply pipe 11 and the return pipe 13 in the form of a ladder. The spacing between the support tubes 15 is such that the blades 9 do not come into contact with each other when the blades 9 are supported by the support tubes 15. Further, the support tubes 15 are arranged parallel to each other at regular intervals, that is, at the above-mentioned intervals. Further, the support pipe 15 communicates with the water supply pipe 11 and the return pipe 13, and the cold and hot water in the water supply pipe 11 is communicated with the support pipe 11.
5 and enters the return pipe 13. In this case, the heat transfer unit 7 includes a cold/hot water circulation pump and a heat exchanger, and supplies water to the water supply pipe 11 and receives water from the return pipe 13 . The blades 9 are supplied with cold heat from the support tube 15. However, the heat exchanger of the heat transfer unit 7 may be omitted, cold and hot water may be produced using a hot water boiler or a refrigerator, and this cold and hot water may be supplied to the heat transfer unit 7. The structure of the blade 9 is shown in Fig. 2 (B
), both ends of the flat cylindrical body are closed with side plates 17, and the side plates 1
A support tube 15 is passed between 7 and 17, and the part where the support tube 15 passes through the side plate 17 has a rotatable fitting structure, and the blade 9 has a variable inclination angle around the support tube 15. ing. Further, a heat radiator 20 is housed inside the blade 9, and this is a thin plate having good heat conduction properties wound around the support tube 15 and bent in a serpentine shape so as to be in contact with the inner wall surface of the blade 9. , transmits the heat of the cold and hot water flowing in the support tube 15 to the blades 9,
The blades 9 act as a cold/heat radiator. Furthermore,
A string 19 in which the blades are connected in series from top to bottom is provided near the end of the blade 9, and an elastic body 21 is connected in series to the upper end of the string 19, and the upper end of this elastic body 21 is connected to the ceiling 23. ing. The expandable body 21 contracts when the surroundings are cold, such as in winter, and expands when it is hot, such as in summer. A material with a large expansion/contraction difference is appropriate, and a material made of shape memory alloy and formed like a coil spring is used. Therefore, when it is cold, the stretchable body 21 contracts and rotates the blades 9 near the horizontal position via the string 19, but when it is hot, it stretches and rotates the blades 9 closer to the vertical position. In this way, the thermal radiation of direct sunlight incident through the window glass 3 is controlled. In this case, if the action of the elastic body 21 is unnecessary in summer or winter because the temperature of the blade 9 itself is adjusted, the elastic body 21 may be removed and the string 19 may be operated manually. Of course, without removing the string 1
9 may be adjusted. Furthermore, in the illustrated embodiment, the stretchable body 21 is suspended from the ceiling 23 so that the stretchable body 21 is easily exposed to direct sunlight. The ends of the expandable body 21 may be locked on the side surface (inside), and the blades 9 may be arranged in parallel in the lateral direction. In this case, the support tubes 15 are vertical and their parallel direction is horizontal. The water supply pipe 11 is placed at the bottom, and the return pipe 13 is placed at the top.
