DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind having a cooling / radiating function which is mounted inside a window to improve a cooling / heating effect.

[0002]

2. Description of the Related Art In order to reduce the influence of the amount of solar radiation on the indoor temperature environment, conventional blinds are blades obtained by forming a thin synthetic resin sheet or a thin metal sheet into an elongated plate shape.
Are arranged in the vertical or horizontal plane direction, and the inclination angle of the blade can be arbitrarily changed. That is, when the solar radiation is strong, the inclination angle of the blade is changed so that the surface of the blade is perpendicular to the incident direction to reduce the amount of solar radiation entering the room.

[0003]

The perimeter portion having a window causes cold draft due to cold radiation by the window glass in winter, and the convection of cold air flowing in the direction of the floor causes uneven heating temperature distribution. Was giving. Even in summer, heat radiation occurs between the inside of the window glass and the blinds, and with conventional blinds, the change in outside air temperature is directly changed by the perimeter and the thermal load fluctuates, and this effect could not be excluded. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a longitudinal section of the perimeter 1. A blind 5 is attached inside the window glass 3 in parallel. A heat transfer unit 7 is disposed as a heat source of the present invention behind the ceiling, and the transfer unit 7 circulates and supplies a heat medium that transmits cold heat to the blind 5. The heat transfer unit 7 is an indoor unit of a heat pump, and the heat medium may be gas, and the heat medium may be cold or hot water.
May be an auxiliary water pump. In the blind 5, vanes having good heat conductivity are juxtaposed vertically or horizontally parallel to the plane direction of the window glass 4, and the heat transfer unit 7 supplies cold heat to the vanes. With such a configuration, the surface temperature of the blind 5 is cooled to around 18 to 20 degrees Celsius in summer,
The blind 5 itself is a cold radiant panel to reduce the amount of solar radiation and cross-flow heat from the window glass 3. In winter, the surface temperature of the blind 5 is heated to around 30 degrees Celsius to radiate heat.
Panels and no cold draft.

FIG. 2 shows an embodiment of the blind 5. FIG. 2A is a front view of the blind 5, and FIG. 1B is a view taken on line BB of FIG. That is, FIG. 2B shows a cross section of the blade 9 for explanation. The blind 5 has horizontally long blades 9 arranged in parallel in a vertical direction, and rotatably supports both ends thereof. A water supply pipe 11 is vertically arranged at the left end of the blade 9, and a return pipe 13 is provided at the right end of the water supply pipe 1.
It is piped in parallel with 1. A support pipe 15 is provided between the water supply pipe 11 and the return pipe 13 in a ladder shape.
The distance 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 tube 15. The support pipes 15 extend at a constant interval, that is, in parallel with each other at the above-mentioned interval. Further, the support pipe 15 communicates with the water supply pipe 11 and the return pipe 13, and the cold and hot water of the water supply pipe 11 is supplied to the support pipe 1.
5 into the return pipe 13. In this case, the heat transfer unit 7 includes a cold / hot water circulation pump and a heat exchanger, sends water to the water supply pipe 11, and receives water from the return pipe 13. The blade 9 is 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 by a hot water boiler or a refrigerator, and the cold and hot water may be supplied to the heat transfer unit 7. The structure of the blade 9 is shown in FIG.
Both ends of the flat cylindrical body are closed with side plates as shown in FIG.
The support tube 15 is passed through the side plate, and the portion where the support tube 15 penetrates the side plate has a rotatable fitting structure.
The tilt angle is variable around 5. Furthermore, the wing 9
A radiator 20 is accommodated in the inside of the support tube 15. The heat radiator 20 is wound around a support tube 15 and has a good heat conduction characteristic.
The heat of the cold / hot water flowing through the inside is transmitted to the blades 9 so that the blades 9 act as a heat radiator. Furthermore, near the end of the blade 9, as a connecting member of the present invention, a string 19 in which the blades are connected in series from top to bottom is provided, and an elastic body 21 is connected in series to the upper end of the string 19. The upper end of the elastic body 21 is the ceiling 23
Connected to The elastic body 21 contracts when the surroundings are cold, such as in winter, and expands when it is hot, such as in summer. A material having a large difference in expansion and contraction is appropriate, and a material formed of a shape memory alloy like a coil spring is used. Therefore, when it cools down, the elastic body 21 contracts and the blades 9 are each rotated near the horizontal position via the string 19, but when it is hot, it expands and rotates toward the vertical position. In this way, the window glass 3
Moderates the heat radiation of direct sunlight entering from In that case,
In summer or winter, if the action of the elastic body 21 is unnecessary in relation to adjusting the temperature of the blade 9 itself, the elastic body 21 may be removed and the cord 19 may be manually operated. Of course, the string 19 may be adjusted without being removed. Further, the present invention is not limited to the embodiment, so that the elastic body 21 is easily exposed to direct sunlight.
In the illustrated embodiment, the elastic body 21 is suspended from the ceiling 23, whereas the side of the window opening of the outer wall or the side of the wall (inside).
Alternatively, the ends of the elastic body 21 may be locked, and the blades 9 may be arranged side by side in the lateral direction. In this case, the support tubes 15 are vertical, and the parallel direction is the horizontal direction. The water supply pipe 11 is arranged below and the return pipe 13 is arranged above.

[0008]

As described above in detail, according to the blind having the cool heat radiation function of the present invention, since the cool heat is supplied to the blade having a variable inclination angle, the blind has a normal blind function and a perimeter portion. This has the effect of canceling out the cooling radiation caused by the outside air temperature and neglecting the thermal load fluctuation characteristics of the perimeter and the interior.

Therefore, it is advantageous in that the determination and arrangement of the heat convection path, the blowing position, and the return gallery position of the air conditioning equipment can be extremely simplified. In addition, in winter, cold radiation and cold draft from the window glass can be reduced, and in summer, the solar heat load can be reduced, thereby providing a comfortable thermal environment for residents. In other words, the convection of air is extremely slow.
Not only become burned, the heat distribution is also become uniform.
