Then, warm air or cold air from the air conditioner 110 is entangled between the upper floor plate 103 and the lower floor 102, and is further blown into the office room 101 through the floor openings 105, 105 of the upper floor plate 103.

[0005]

[Problems to be solved by the device]

 However, since the floor opening 105 is conventionally provided in the upper floor plate 103, in order to spread the cold air or the warm air throughout the office room 101, it is necessary to strongly blow the cold air or the warm air upward as an air current. Therefore, the airflow directly touched the human body directly, and the sensation of receiving the airflow was not always good.

[0006] Furthermore, in particular, during cooling in the summer and the like, cold air is supplied from the floor opening 105 into the office room 101, but since the floor opening 105 is provided in the upper floor plate 103, this cold air is accumulated in the lower layer, The temperature on the lower layer side in the office room 101 was always low, and the temperature distribution in the office room 101 could not be made uniform. Therefore, the partition 109 provided on the upper floor plate 103 mainly has a function of appropriately dividing the office room 101, but greatly contributes to comfort such as temperature distribution in the office room 101. There was no

The present invention has been made to solve the above-mentioned problems, and its purpose is to make the air flow of warm air or cold air supplied into the room through the floor opening comfortable, and to keep the temperature inside the room comfortable. It is an object of the present invention to provide a floor-blowing air-conditioning partition and a floor-blowing air-conditioning system using the floor-blowing air-conditioning partition, which can make the distribution uniform and improve indoor comfort.

[0008]

[Means for Solving the Problems]

 The invention of claim 1 is provided with a pair of plate members facing each other through an internal space in which cold air or warm air is supplied from the floor opening provided in the floor plate in a state of being shielded from the indoor space, and the upper side of the plate member is provided. A cold air outlet that blows out cool air is formed, and a warm air outlet that blows out warm air is formed on the lower side of the plate material.The inside of a pair of plate materials is located between the cold air outlet and the warm air outlet from the floor opening. The feature is that a shielding member that shields air is provided so as to be openable and closable.

According to the second aspect of the present invention, a room, a free access floor having a double floor structure in which an upper floor plate is arranged on a lower floor of the room, and a floor opening provided in the upper floor plate of the free access floor 2. The partition according to claim 1, which is installed directly on the floor opening, a chamber formed on the ceiling back side of the building, a suction port provided on the ceiling, and an air supply port and chamber of the free access floor. It is characterized by comprising a duct connecting the air outlet and an air conditioner interposed in the duct.

(Operation) In Claims 1 and 2, during cooling such as summer, the shielding member is in an open state, and air is in a state of flowing in the internal space between the pair of plate members. Therefore, cool air is carried from the floor opening of the floorboard to the cool air outlet on the upper side of the partition, and blows out into the room through the cool air outlet, and this cool air becomes a downward airflow and flows toward the lower layers of the room. .

At the same time, when cold air passes through the partition, radiant heat is radiated from the partition cooled by the cool air to perform radiation cooling. On the other hand, during heating such as in winter, the shielding member is closed, and air does not flow above the shielding member in the internal space between the pair of plate members. Therefore, the warm air blown out from the floor opening of the floorboard is blocked by the shielding member and guided to the warm air outlet. This warm air is blown into the room through the warm air outlet formed on the lower side of the partition, and becomes an upward airflow, which flows toward the upper layers of the room.

At the same time, a part of the warm air is blown out from a cool air outlet formed on the upper side of the partition to warm the partition, whereby radiant heat is radiated from the partition to perform radiant heating.

The partition 9 is constructed by arranging a plurality of partition units 20 shown in FIG. 2 in series, and the structure of the partition unit 20 will be described in detail with reference to FIGS. 1 and 2.

In the figure, the partition unit 20 includes a pair of plate members facing each other through an internal space 22 in which cold air or warm air is supplied from the space 21 between the upper floor plate 3 and the lower floor 2 through the floor opening 5. 23, 23 are provided. An appropriate number of spacers 24 are sandwiched between the pair of plate members 23, 23. A bolt 25 is inserted into the spacer 24 and tightened with a nut 26 so that the pair of plate members 23, 23 has a predetermined distance. It is held parallel to each other. L-shaped angle members 27, 27 are fixed to the lower ends of the plate members 23, 23 by welding, and a plate piece 28 is placed on the angle members 27, 27, and the plate piece 28 is opened in the panel 12. The partition unit 20 is fixed to the upper floor plate 3 by pressing with bolts 29, 29 penetrating the small holes 16, 16. A warm air outlet 30 including a slit hole 30B is formed at the bottom of each plate member 23. The cut piece 30A formed simultaneously with the processing of the slit hole 30B faces obliquely downward. A shield plate 31 is rotatably supported on the upper portion of the warm air outlet 30 of each plate member 23, and the tip end of the shield plate 31 is made of a shape memory alloy, a bimetal, etc. The member 32 has a structure that opens and closes according to the temperature.

A lid member 34 having an inverted triangular cross section is slidably mounted on the upper end of the partition unit 20 via a holding member 33 fixed to the partition unit 20 so as to stop at any position in the vertical direction. A cold air outlet 35 for blowing cold air is formed between the lid member 34 and the upper end 23A of the plate member 23. By moving the lid member 34 in the vertical direction, the amount of cold air blown out from the cold air outlet 35 is adjusted.

As shown in FIGS. 2 and 4, end members 23B and 23C are provided at the ends of the plate member 23, and the pair of plate members 23 and the end members 23B and 23C surround the internal space 22. A cross-sectional shape is formed. As the partition unit 20, there are various shapes such as a linear shape, an L-shape, and a T-shape. As an example, FIGS. 2 and 4 show the linear shape. The partition 9 is formed by combining a plurality of units 20. The partition 9 has a gate-like shape having the same shape as the floor opening 5, and has a shape like a straight line extending to the upper right side. There is.

Next, the operation of this embodiment will be described. FIG. 3 shows a state during cooling in the summer, etc. At this time, in each partition unit 20 (shown in FIG. 1), the elastic members 32, 32 contract and the shield plates 31, 31 rotate downward, In the open state, cold air can pass through the internal space 22 of the partition unit 20.

Therefore, the cool air is carried from the floor opening 5 of the upper floor plate 3 to the cool air outlet 35 on the upper side of the partition 9 and blown into the office room 1 through the cold air outlet 35. Then, cool air is sent from the air conditioner 10 to the space 21 via the duct 11, and the cool air is sent from the space 21 to the cool air outlet 35 of the partition 9 via the floor opening 5 and from this cold air outlet 35. The air blows upward in the room 1, and then the cool air becomes a downward airflow and flows toward the lower layer in the office room 1, and the temperature in the upper layer side in the office room 1 decreases, so that the temperature distribution is in the office room 1. Is uniform over the entire area. At the same time, when cold air passes through the partition 9, radiant heat is radiated from the partition 9 cooled by the cold air, and radiant cooling is performed.

On the other hand, a state during heating such as winter is shown in FIG. At this time, in each partition unit 20 (shown in FIG. 1), the elastic members 32, 32 are extended and the shield plates 31, 31 are pivoted upward and are in a closed state. Therefore, the warm air introduced into the internal space 22 of the partition unit 20 is blocked by the shield plates 31 and 31 and cannot pass above it except the warm air that warms the surface of the partition unit 20.

Then, warm air is sent from the air conditioner 10 to the space 21 through the duct 11, and this warm air is guided from the space 21 through the floor opening 5 to the warm air outlet 30 of the partition 9 and cut into pieces. While being guided by 30A, it blows downward from the warm air outlet 30 into the office room 1 and then becomes an upward airflow that flows into the office room 1 and the temperature on the lower layer side in the office room 1 rises, resulting in a temperature distribution. Becomes uniform over the entire office room 1. At the same time, when a part of warm air passes through the partition 9, radiant heat is radiated from the partition 9 warmed by the warm air to perform radiant heating, which has a secondary effect on heating.

According to the above configuration, the cold air outlet 35 and the warm air outlet 30 are provided in the partition 9, and the cool air is discharged from the cold air outlet 35 on the upper side of the partition 9 to the lower layer side in the office room 1. Since the hot air flows toward the upper layer side in the office room 1 from the warm air outlet 30 on the lower side of the partition 9, the floor opening 105 shown in FIG. Even if the blowing speed of cold air or warm air is slower than that of the conventional example in which cold air or warm air is blown out as a stream of air from the bottom to the top, the cold air or warm air will naturally flow through the entire office room 1. Spread around. Further, in the partition 9, the supply range of the cold air outlet 35 and the warm air outlet 30 is less restricted and can be widened, and cold air or warm air can be blown out over a wide range. . Therefore, the cold air or the warm air blown out from the cold air blowout port 35 or the warm air blowout port 30 can touch the human body weakly and improve the feeling of receiving the airflow. Further, during cooling in the summer or the like, cool air is supplied from the cool air outlet 35 on the upper side of the partition 9, and this cool air flows toward the lower layer side in the office room 1, and the temperature of the upper layer side in the office room 1 is low. Therefore, the temperature distribution in the office 1 can be made uniform throughout. Moreover, in combination with this, the radiant cooling is performed from the partition 9 so that the occupants in the office room 1 can be cooled.

On the other hand, during heating such as in winter, warm air is supplied from the warm air outlet 30 on the lower side of the partition 9, and this warm air flows toward the upper layer side in the office room 1 and the temperature of the lower layer side in the office room 1. As a result, the temperature distribution in the office room 1 can be made uniform throughout. Moreover, together with this, since a part of warm air is passed to the partition 9 and the radiant heating is performed from the partition 9, it is possible to give a comfortable warmth to the occupants in the office room 1.

In the present embodiment, the shield plate 31 has a structure that automatically opens and closes according to temperature by the expansion and contraction member 32 made of a shape memory alloy, a bimetal, etc., but without such a structure. However, it is possible to manually open and close the structure. Further, in the present embodiment, the warm air outlet 30 is formed integrally with the plate member 23, but the warm air outlet port 30 may be detachably provided in the plate member 23.

Further, in the present embodiment, the partition 9 is configured by assembling a plurality of partition units 20 side by side in succession, but the partition does not necessarily have to have such a configuration. It is also possible to form one partition unit having a linear cross section by lengthening the lid member 34 and the like. Further, in the present embodiment, the cut piece 30A is directed obliquely downward, but it may be directed in the horizontal direction.

Further, in the present embodiment, the surface finishing unit material 14A, 14B, 14C, 14E and the like are appropriately combined and placed on each panel 12 and fixed, whereby the surface finishing unit material is fixed. Although the air supply ports 19A, 19B, 19C, etc. of 14A, 14B, 14C, etc. are continuously formed, a floor opening 5 having a shape in which a straight part is extended is formed on the upper right side of the gate shape as shown in FIG. The shape of the floor opening is not limited to the above shape, and various floor opening shapes can be arbitrarily combined according to the layout requirements. For example, the surface finishing unit materials 14A may be arranged side by side in a row to form a linear floor opening. In this case, the shape of the partition must correspond to the shape of the floor opening.

Further, in the present embodiment, all the panels 12 are provided with the opening small hole group 17 composed of a large number of opening small holes 16 for blowing air, but the floor of the upper floor plate 3 is It may be configured so that some panels that are not likely to be used as openings are not provided with openings perforations.

In addition, in the present embodiment, an appropriate number of spacers 24 are sandwiched between the pair of plate members 23, 23, the bolt 25 is passed through the inside of the spacer 24, and the spacer 26 is tightened with the nut 26. As a result, the pair of plate members 23, 23 are held in parallel at a predetermined distance, but without using the spacer 24, the bolt 25, and the nut 26, the plate-shaped bracket sandwiched between them is spot-welded. By doing so, the pair of plate members 23, 23 can be held in parallel at a predetermined distance.

FIG. 11 shows a sectional view of a partition for floor blowout air conditioning according to the second embodiment of claim 1. Although the partition according to the second embodiment has the same structure as the partition according to the first embodiment. , Only the part indicated by the chain double-dashed line M is different. In the figure, the partition 9 in the first embodiment shown in FIG. 1 has a height up to the middle part of the office room 1, while the partition 41 in this embodiment has a height reaching the ceiling 42. A large number of partition units 43 are arranged side by side. At the upper end of the partition unit 43, a cold air outlet 44 composed of a slit hole 44B is formed. The cutting piece 44A formed at the same time as the processing of the slit hole 44B faces obliquely upward. A damper 46, which controls the amount of cold air blown out, is provided inside the cold air outlet 44 of the pair of plate members 45, 45 that form the partition unit 43.

According to the second embodiment having the above structure, the same effect as that of the first embodiment is obtained. In addition, in the present embodiment, the cut piece 44A is directed obliquely downward, but it may be oriented horizontally. Further, the present invention is not limited to the floor structure as shown in FIG. 4, and can be installed on a normal floor structure for floor blowing air conditioning.

[Effect of the invention]

 As described above, according to the present invention, the cool air outlet and the warm air outlet are provided in the partition, and the cool air flows from the cool air outlet on the upper side of the partition toward the lower layer side of the room and the lower part of the partition. Since warm air flows from the side warm air outlet toward the upper layer of the room, compared to the conventional example in which the floor opening is provided in the upper floor plate and cool air or warm air is blown into the room from below to above as an airflow. Therefore, even if the blowing speed of cold air or warm air is slow, the cold air or warm air naturally spreads throughout the room. Further, in the partition, the supply range of the cold air outlet and the warm air outlet is not limited to a large extent and can be widened, and cold air or warm air can be blown out over a wide range. Therefore, the cold air or the warm air blown out from the cold air outlet or the warm air outlet can weakly touch the entrance and improve the feeling of receiving the airflow.

Further, during cooling in the summer, etc., cool air is supplied from the cool air outlet on the upper side of the partition, this cool air flows toward the lower layer side of the room, and the temperature of the upper layer side of the room also decreases, resulting in a temperature distribution in the room. Can be made uniform throughout. At the same time, the radiation cooling from the partition makes it possible to give coolness to the occupants in the room.

On the other hand, during heating such as in winter, warm air is supplied from the warm air outlet on the lower side of the partition, the warm air flows toward the upper layer side of the room, and the temperature of the lower layer side of the room also rises, resulting in a temperature distribution in the room. Can be made uniform throughout. At the same time, since a part of warm air is supplied to the partition and radiant heating is performed from the partition, it is possible to give a comfortable warmth to the occupants in the room together with this.
