Abstract

PURPOSE:To make the temperature distribution in a room uniform by providing partitions on a floor, by which either warm air or cool air is blown from inside spaces of partitions into a room through cool air outlets provided on the upper parts or warm air outlets provided on the lower parts. CONSTITUTION:Partition assemblies 20 are kept in an open state with extension members 32 drawn in and shutter plates 31 rolled down. Therefore, cool air is allowed to pass through inside spaces 22 of the partition assemblies 20. The cool air is sent from an air conditioner 10 to a space 21 through a duct 11, and blown upward from the space 21 into an office room through cool air outlets 35 located on partition walls 9 of the partition assemblies 20. Then, the cool air flows down through the office room so that the temperature in the upper zone of the office room drops and the temperature distribution in the office room becomes uniform. At the same time, when the cool air passes through between the partition walls 9, radiant heat is radiated from the partition walls 9 cooled by the cool air, and radiant cooling takes place.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor-blowing air conditioner installed in a raised floor with a double floor structure.

[Conventional technology]

In recent years, as office automation has progressed, there have been an increasing number of cases in which double-floor structure free access floors are being adopted in order to make it easier to change a large amount of wiring due to changes in the layout of office equipment, computers, etc. However, the working environment is becoming poor due to heat generation from equipment. Therefore, it is also required to improve the comfort of indoor occupants.

In order to improve indoor comfort and make effective use of the space under the floor,

Floor openings 105, 105 are provided in the upper floor plate 103 of this free access floor 104, while a ceiling suction port 108,
108 are provided. Partitions 109, 109 are provided on the above-mentioned upper floor plate 103.

The air supply port 104A of the free access floor 104 of the office room 101 and the air discharge port 106A of the chamber 106 are connected by a duct 111 in which an air conditioner 11O is interposed.

Thus, warm or cold air is supplied from the air conditioner 110 between the upper floor board 103 and the lower floor 102, and furthermore, the air is supplied between the upper floor board 103 and the lower floor 102.
The air blows out into the office room 101 through the floor openings 105 and 105 of 03.

(Problem to be Solved by the Invention) However, in the conventional floor blowing air conditioner, since the floor opening 105 is provided in the upper floor plate 103, it is difficult to distribute cool air or warm air throughout the office room 101. It is necessary to strongly blow cold or warm air upwards as an air current, and therefore, the air current comes into direct contact with the human body, and the sensation of receiving the air current is not necessarily good. Sometimes the cold air is floor opening 10
5 into the office room 101, but since the floor opening 105 is provided in the upper floor board 103, this cold air accumulates in the lower layer, and the temperature in the lower layer in the office room 101 is always low. It was not possible to make the temperature distribution uniform.

Furthermore, when changing the layout of office room 101,
Along with the partition 109, the floor opening 105 also connects to the upper floor board 103.
This floor opening 105 is usually located at the upper floor + Fi. 103, the series of operations from removal to installation were troublesome.

This also made it less flexible to change the layout. Since the floor opening 105 is exposed to the upper floor plate 103, the floor opening 105 becomes an obstacle when changing the layout, making it impossible to arrange equipment, desks, etc. in appropriate positions, and providing flexibility in changing the layout. was bad.

The present invention was made to solve the above-mentioned problems, and its purpose is to make the flow of warm or cold air supplied into the room from the floor opening feel comfortable, and to make the temperature distribution in the room uniform. Furthermore, it is an object of the present invention to provide a floor blowing air conditioner that improves flexibility when changing the layout. [Means for Solving the Problems] In order to achieve the above-mentioned problems, the present invention guides warm or cold air from an air conditioner between the upper floor board and the lower floor of the double floor through the floor opening provided in the upper floor board. In a floor air conditioner that supplies indoors, it has an internal space from within the double floor to which hot or cold air is supplied through a floor opening, and a cold air outlet formed on the upper side or a warm air outlet formed on the lower side. A partition is provided on the upper floor plate for blowing either cold air or warm air from the interior space into the room through an outlet.

[Function] In the present invention, during air conditioning in summer, etc., cold air is blown into the room from inside the double floor through the cold air outlet formed on the upper side of the partition, and this cold air becomes a downward airflow and flows into the room. flows toward the lower layer of

At the same time, when cold air passes through the partition, radiant heat is radiated from the partition cooled by the cold air, resulting in radiant cooling.

On the other hand, during heating in winter, warm air blows into the room from inside the double floor through the warm air outlet located at the bottom of the partition.
This warm air becomes an upward air current that flows toward the upper layers of the room.

At the same time, a portion of the warm air is blown out from the cold air outlet formed on the upper side of the partition to warm the partition, thereby radiating heat from the partition and performing radiant heating.

As shown in FIG. 2, a partition 9 having a height up to the middle of the office room 1 is arranged along the periphery of the floor frontage 5 when viewed in plan.

The partition 9 is constructed by arranging a plurality of partition units 20 shown in FIG. 4 in series, and the details of the structure of the partition units 20 are shown in FIGS. 3 and 4. In the figure, the partition unit 20 includes a pair of plates 23, 23 facing each other with an internal space 22 to which cold or warm air is supplied from a space 21 between the upper floor plate 3 and the lower floor 2.

An appropriate number of spacers 24 are provided between the pair of plates 23 and 23.
is supported, and by passing a bolt 25 through the spacer 24 and tightening it with a nut 26, the pair of plates 23, 23 are held in parallel with a predetermined distance apart. L-shaped angle members 27 and 27 are fixed to the lower ends of the plate members 23 and 23 by welding, respectively.
A temporary piece 28 is placed on top of 27, and this plate piece 28 is attached to the panel 1.
The partition unit 20 is fixed to the upper floor plate 3 by holding it down with bolts 29.29 that pass through the small opening holes 16.16 of the partition unit 2.

A warm air outlet 30 consisting of a slit hole 30B is formed in the lower part of each plate member 23. Slit hole 30.
The cut piece 30A, which is shaped at the same time as the processing of B, faces diagonally downward. An opening/closing plate 31 is rotatably supported on the upper part of the warm air outlet 30 of each plate member 2'3.
The tip of this opening/closing plate 31 has a structure that opens and closes depending on the temperature by an expandable member 32 made of shape memory alloy, bimetal, etc. provided on the plate 23.

Furthermore, a lid member 34 having an inverted triangular cross section is slidably provided at the upper end of the partition unit 20 via a holding member 33 fixed to the partition unit 20 so as to stop at an arbitrary position in the vertical direction.
A cold air outlet 35 for blowing out 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.

Next, the operation of this embodiment will be explained.

FIG. 1 shows the state during cooling in summer, etc. At this time, in each partition unit 20 (shown in FIG. 3), the expandable members 32.3
2 retracts, the opening/closing temporary 31.31 rotates downward,
It is in the open state. Therefore, cool air is allowed to pass through the internal space 22 of the partition unit 20.

Thus, cold air is sent from the air conditioner 10 to the space 2l through the duct 1l, and this cold air is blown upward from the space 2l into the office room l through the cold air outlet 35 of each partition unit 20 of the partition 9. Thereafter, the cold air flows into the office room 1 as a downward air current, and the temperature in the upper M01 of the office room 1 decreases, so that the temperature distribution becomes uniform throughout the office room 1.

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, thereby performing radiant cooling. On the other hand, the state during heating, such as in winter, is shown in FIG. At this time, in each partition unit 20 (shown in Figure 3),
The telescopic member 32.32 is extended, and the opening/closing member 31.31 is rotated upward to be in the closed state. Therefore, the warm air guided into the internal space 22 of the partition unit 20 is transferred to the opening/closing plate 3.
1.31, and above it is the partition unit 2.
Except for warm air that warms the surface of 0, no air can pass through it.

Thus, warm air is sent from the air conditioner 10 to the space 21 via the duct 11, and this warm air is guided from the space 2l through the warm air outlet 30 of each partition unit 20 of the partition 9 by the notch piece 30A. office room 1
Afterwards, the air flows upward into the office room 1, increasing the temperature in the lower layer of the office room 1, and making the temperature distribution uniform throughout the office room 1.

At the same time, when a portion of the warm air passes through the partition 9, radiant heat is radiated from the partition 9 warmed by the warm air, radiant heating is performed, and a secondary effect is exerted on the heating.

According to the above arrangement, the cold air outlet 35 and the warm air outlet 30 are provided in the partition 9, and the cold air flows from the cold air outlet 35 on the upper side of the partition 9 toward the lower level in the office room 1. Warm air outlet 30 on the lower side of the partition 9
Since warm air flows toward the upper layer in the office room 1, the floor opening 105 shown in FIG.
Compared to the conventional example in which cool air or warm air is blown out from the bottom upwards in the office room 10 It spreads throughout the office room 1. Further, the supply range of the cold air outlet 35 and the warm air outlet 30 can be widened, and cold air or warm air can be blown out over a wide range. Therefore, the cold air or warm air blown out from the cold air outlet 35 or the warm air outlet 30 touches the human body weakly and can improve the feeling of being exposed to the airflow.

Also, during cooling in summer, etc., cold air is supplied from the cold air outlet 35 on the upper side of the partition 9, and this cold air flows toward the lower part of the office room 1, lowering the temperature of the upper part of the office room 1. , the temperature distribution within the office room l can be made uniform throughout. Moreover, since radiant cooling is performed from the partition 9, the occupants in the office room 1 can be kept cool.

On the other hand, during heating in winter, etc., 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 in the office room 1, increasing the temperature in the lower layer in the office room 1. , the temperature distribution within the office room l can be made uniform throughout. Moreover, in conjunction with this, a part of the warm air is allowed to flow into the partition 9.
Since radiant heating is performed from the office room 1, it is possible to provide comfortable warmth to the occupants in the office room 1.

Furthermore, when changing the layout of the office room 1, if the positions of the partition 9 and the floor opening 5 are moved,
Since the positions of the cold air outlet 35 and the warm air outlet 30 are changed, the floor opening 105 fixed to the upper floor plate 103 in the conventional example shown in FIG.
This eliminates the need to move the equipment to another location and install it. Furthermore, when changing the layout, there is no need to take special consideration to the movement of the floor opening 5 as described above, and flexibility in changing the layout can be ensured.

In addition, the partition 9 has a cold air outlet 30 and a warm air outlet 35.
Since the floor opening 5 is not exposed above the upper floor plate 3, therefore, when changing the layout, equipment, desks, etc. can be placed in appropriate positions without being obstructed by the floor opening 5.
This has the effect of ensuring flexibility in changing the layout.

In this embodiment, a cuppet is used as the surface finishing material l3, but the surface finishing material l3 is not limited to this, and for example, a tile can also be used.

In addition, in this embodiment, all the barrels 12 have the following:
Opening hole group l consisting of a large number of air blowing opening holes 16
However, it is possible to take care not to provide opening small hole groups in some panels that are not likely to be used as floor openings in the upper floor board 3.

Furthermore, in this embodiment, the surface finishing unit material 14
By appropriately combining A, 14B, 19C, 14E, etc. and placing and fixing them on each panel 12, the air supply port 1 of the surface finishing unit material 14A, 14819C, etc.
9A, 19B, 19C, etc. are formed in succession to form a floor opening 5 shaped like an extended straight part on the upper right side of a portal as shown in FIG. The shapes of various floor openings can be arbitrarily combined according to the layout requirements without being limited to the above. For example, the surface finishing unit materials 14A may be arranged in a horizontal row to form a linear floor opening.

In this embodiment, the opening/closing plate 31 has a structure that automatically opens and closes depending on the temperature using an expandable member 32 made of shape memory alloy, bimetal, etc., but it can be opened and closed manually without such a structure. It is also possible to have a structure that allows

Further, in this embodiment, the partition 9 has a height that reaches the middle of the office room 1, but instead of the partition 9, it has a height that reaches the ceiling and has a cold air outlet at the top. It is also possible to use formed partitions. Even in such a case, the same effect 1 as in this embodiment can be obtained.
be effective.

Further, in this embodiment, the cut piece 30A faces diagonally downward, but it can also face horizontally.

In addition, in this embodiment, an appropriate number of spacers 24 are supported between the pair of plate materials 23 and 23, and by passing bolts 25 through the spacers 24 and tightening them with nuts 26, the pair of spacers 23 and 23 are supported. Plate materials 23 and 23 are held in parallel at a predetermined distance apart, but a pair of plate materials 23 and 23 are separated by spot welding a plate-shaped bracket supported between them without using spacers 24, bolts 25, and nuts 26. The plates 23.23 can also be kept parallel at a predetermined distance apart.

〔Effect of the invention〕

As described above, according to the present invention, the cold air outlet and the warm air outlet are provided in the partition, and the cold air flows from the cold air outlet on the upper side of the partition toward the lower part of the room, and Since warm air flows from the side warm air outlet towards the upper part of the room, compared to the conventional example in which a floor opening is provided in the upper floor board and cool or warm air is blown into the room from the bottom upwards as an air current. Therefore, even if the blowing speed of cold or warm air is slow, the cold or warm air will naturally spread throughout the room. Further, the supply range of the cold air outlet and the warm air outlet can be widened, and cold air or warm air can be blown out over a wide range. Therefore,
The cold air or warm air blown out from the cold air outlet or the warm air outlet touches the human body weakly and can improve the sensation of receiving airflow.

In addition, during cooling during the summer, cold air is supplied from the cold air outlet at the top of the partition, and this cold air flows toward the lower part of the room, lowering the temperature in the upper part of the room, and improving the temperature distribution in the room as a whole. It can be made uniform throughout. At the same time, since radiant cooling is carried out through the partitions, it is possible to provide coolness to the occupants in the room.

On the other hand, during heating in winter, warm air is supplied from the warm air outlet at the bottom of the partition, and this warm air flows toward the upper layer of the room, increasing the temperature at the lower layer of the room, and changing the temperature distribution in the room as a whole. It can be made uniform throughout. At the same time, since some of the warm air flows through the partitions, radiant heating is performed from the partitions, which, together with this, can provide comfortable warmth to the occupants of the room.

Furthermore, when changing the layout of a room, if the positions of the partition and floor opening are moved, the positions of the cold air outlet and the warm air outlet will be changed accordingly. This eliminates the need to remove and move to another location on the upper floorboard for installation. Furthermore, when changing the layout, there is no need to take special consideration to the movement of the floor opening as described above, and flexibility in changing the layout can be ensured.

In addition, since the partition is equipped with a cold air outlet and a warm air outlet, the floor opening is not exposed above the upper floorboard, and therefore, when changing the layout, equipment, desks, etc. do not get in the way of the floor opening. This has the effect of ensuring flexibility in changing the layout by allowing the layout to be placed in an appropriate position without being overwritten.
