JP 2003-213901 A

By the way, in the method of providing an opening in the floor described in Patent Document 1, the air-conditioning air supply amount to each living room is determined in accordance with the differential pressure between the underfloor space and the living room. It is difficult to control the air conditioner and to start and stop the air conditioning for each room, and there is a case where a room temperature difference occurs between the north and south rooms in the dwelling unit, and the air conditioning cannot be comfortably performed.
On the other hand, according to the method of providing a mechanism for manually adjusting the ventilation area of the grill, the opening area can be adjusted, so the temperature of each room can be adjusted by the occupant, but it is not easy to adjust because it is manual, and there are cases where labor is required. is there.
In addition, according to the method that automatically opens and closes the automatic open / close damper at two positions according to the sign of the deviation between the detected temperature and the set temperature in the room thermo remote controller, the room temperature can be set for multiple rooms, and air conditioning can be started and stopped for each room. Can be controlled. However, if the temperature detected by the room thermo-remote controller approaches the set temperature during heating operation and the room becomes warm, the automatic open / close damper is closed, and the temperature detected by the room thermo-remote controller is lower than the set temperature, causing the room to become cold. If this happens, the automatic open / close damper will be in the open state, but if the automatic open / close damper is repeatedly opened / closed in this way, the average air supply temperature to the underfloor space may not be raised. As a result, the phenomenon that the temperature of the double floor cannot be raised occurs, and the floor heating effect is reduced.

  The subject of this invention is made | formed in view of the said situation, and it aims at providing the air-conditioning system which can control the temperature of all living rooms separately, and has a floor heating effect in winter.

In the invention according to claim 1, for example, as shown in FIGS. 1 to 6 and FIG. 8, the underfloor space of the double floor 2 formed in the lower part of each living room 10, 11, 12, 13 in the building 1 is provided. The air supply path 2a is configured to allow the air conditioned by the air conditioning unit 3 to pass through the air supply path 2a and be supplied to the floor blowing units 4 provided on the floors of the rooms 10, 11, 12, 13 respectively.

Because it can, it can be connected to the 24-hour ventilation system.
Further, since the outlet is formed in the wall surface of the pit installed on the floor of each room so as to be dropped into the air supply path, the pit itself is extended from the air supply path. It will function as an auxiliary air supply path. Therefore, even if the position of the grille and the cover plate is arbitrarily exchanged, there is an effect that the air-conditioning air supply with the required air volume adjusted by the opening / closing damper is supplied to the living rooms in the pit and through the grille. Accordingly, a comfortable air-conditioning effect of each room by the opening / closing damper and the temperature controller is maintained while allowing the arrangement of the grill and the cover plate to be changed according to a request for changing the layout of the furniture in each room. be able to.
Further, since the damper unit is attached to the wall surface on the building center side of the pit, the outlet and the opening / closing damper face the air supply path. As a result, the air passing through the air supply path can be easily taken into the pit as compared with the case where the outlet and the open / close damper are provided on the wall surface of the pit opposite to the center of the building. The air that has been discharged can be effectively supplied into each room.

The damper unit 5 is mounted at a position higher than the bottom surface 40a of the pit 40.

According to the third aspect of the present invention, since the liquid or dust / dust that falls into the pit from the floor of each living room first falls to the bottom surface of the pit, the damper unit is positioned higher than the bottom surface of the pit. As a result, it is possible to prevent liquid, dust, and waste from entering the underfloor space of the double floor, and to prevent the liquid from reaching the damper unit, thereby preventing contamination of the underfloor space. And has the effect of improving the durability of the equipment.
In addition, liquid, dust, waste, and the like are deposited on the bottom surface of the pit, not in the underfloor space, and cleaning by a resident is easy.

According to the present invention, each room in a building is provided with a floor blowing unit, a damper unit, and a temperature controller, so that all the rooms are individually set to an arbitrary temperature by one air conditioning unit. Can be air-conditioned, that is, multi-room control can be performed. In particular, since the opening of the open / close damper can be controlled to open and close in multiple stages between the fully open state and the fully closed state by the temperature controller, more precise temperature management is possible than in the prior art.
In addition, when the opening / closing damper is controlled to open / close two positions as in the prior art, there is a time zone during which heating and supply air is not supplied to the underfloor space when the opening / closing damper is closed. By opening and closing the opening of the multi-stage between the fully open and fully closed states, heating air is continuously supplied even with a small air volume, and the air temperature in the underfloor space is kept high. It became possible to do. As a result, the floor surface temperature of the room to be heated can be maintained at a high level, so that the air conditioning system can form a comfortable living environment with a high floor heating effect. Moreover, such a floor heating effect can be arbitrarily obtained in all living rooms. Furthermore, this floor heating effect can be controlled for each room.
In addition, by providing ventilation openings in the damper unit, air conditioning is stopped in all living rooms or in each room, and a predetermined amount of air is always supplied from the underfloor space to each room even when the open / close damper is closed.

Since the liquid drops directly, it is possible to more reliably prevent the liquid from reaching the opening / closing damper 5.

Moreover, the said damper unit 5 is attached to the wall surface 40b of the building 1 center side of the said pit 40, as shown in FIGS.
That is, since the damper unit 5 is attached to the wall surface 40b on the building center side of the pit 40, the outlet 41 and the damper unit 5 face the air supply path 2a. As a result, the air passing through the air supply path 2a is allowed to enter the pit 40 as compared with the case where the outlet 41 and the damper unit 5 are provided on the wall surface of the pit 40 opposite to the center of the building. It becomes easy to take in and the air-conditioned air can be effectively supplied into each of the living rooms 10, 11, 12, and 13.

  During the operation of the air conditioning system, the damper unit 5 is controlled to be opened and closed by a calculation result based on a deviation comparison between the room temperature detected by the temperature controller 6 and a set temperature.

On the other hand, the temperature controller 6 includes a temperature sensor (not shown) for detecting the room temperature of each of the rooms 10, 11, 12, and 13, and a temperature setting unit (not shown) for selecting a set temperature. And an opening degree control device (not shown) for controlling the opening degree of the open / close damper 5 based on the deviation between the detected indoor temperature and the set temperature. The temperature controller 6 according to the present embodiment is connected to the main remote controller 6a and can perform various operations such as ON / OFF of the switch.
The control signal generated from the opening control device is sent to the motor control device of the damper unit 5. The calculation and control signal output may be performed by the air conditioning unit 3.

  Further, as described above, since the opening degree of the open / close damper 50 in the damper unit 5 is controlled to open and close in multiple stages between the fully open state and the fully closed state by the temperature controller 6, The damper unit 5 is controlled based on the deviation between the indoor temperature detected by the temperature regulator 6 and the set temperature, as well as being started and stopped and controlled by operating the main switch of the air conditioning unit 3. It is started / stopped / controlled according to the operating status.

  The temperature controller 6 of the present embodiment may be a wall-mounted temperature controller 6 that includes a commercially available temperature sensor as the temperature sensor. Further, a radiation temperature sensor may be attached to the outlet 41 as the temperature sensor to detect the ceiling surface temperature of the living room, and the latter has the merit of greatly reducing the labor of construction / facility construction.

Next, the operation and control of the air conditioning system having the above configuration will be described.
In FIGS. 1 and 2, arrows indicate the air flow. In addition, it is assumed that the air conditioning unit 3, the damper unit 5, the temperature controller 6 and the like constituting the air conditioning system are all in operation.

In cooperation with the indoor unit 31 and the outdoor unit 32, air is heated or cooled via a heat exchanger 31a, and the heated or cooled air is discharged to the air supply duct 33 by the fan 31b. To do.
Outside air taken in from the outside is taken in by the air supply fan 36 and is sent to the indoor unit 31 through the air supply pipe 3a. At this time, the air taken in from outside is passed through the outside air filter 37 to remove dust and the like, and then mixed with the atmosphere in the suction grill 34.

  The air-conditioned air discharged to the air supply duct 33 is discharged to the air supply path 2a in the underfloor space of the double floor 2, and this discharged air passes through the air supply path 2a. And sent to the floor blowing unit 4 provided on the floor of each of the rooms 10, 11, 12, 13.

  On the other hand, in each of the living rooms 10, 11, 12, and 13, the set temperature is selected by operating the temperature setting unit of the temperature controller 6. At this time, the room temperature of each of the rooms 10, 11, 12, and 13 is detected by the temperature sensor of the temperature controller 6, and the opening degree control device determines the room temperature based on the deviation between the detected room temperature and the set temperature. The opening degree of the damper unit 5 is controlled.

  When controlling the opening degree of the damper unit 5, a control signal is sent from the opening degree control device to the motor drive control device of the damper unit 5, and this control signal is received by the motor drive control device that has received this control signal. The motor is driven so as to take an operation according to the signal, and the open / close damper 50 is opened and closed by the motor.

  The opening degree of the damper unit 5 is controlled to be opened and closed in multiple stages between the fully open state and the fully closed state. The multistage here means at least three stages of full open, half open, and full close. For example, 1%, 5%, 10% from 0% opening (fully closed) to 100% opening (fully open). The number of stages is not limited, such as dividing into stages.

  And by controlling the opening degree of the open / close damper 5 in this way, the air conditioned air of a predetermined air volume in each of the living rooms 10, 11, 12, 13 is in the underfloor space of the double floor 2. The air is supplied from the air supply path 2a through the floor blowing unit 4. Therefore, each room 10, 11, 12, 13 can be individually set to an arbitrary temperature and arbitrarily air-conditioned. Moreover, since the opening degree of the damper unit 5 can be controlled to be opened and closed in multiple stages between the fully open state and the fully closed state, precise temperature management becomes possible.

Further, the air thus conditioned passes through the air supply path 2a and is continuously supplied into each of the living rooms 10, 11, 12, and 13, for example, in the winter, by warm air, The underfloor space of the double floor 2 can be warmed. That is, the floor surface temperature of each room 10, 11, 12, 13 to be heated is maintained high, and a high floor heating effect is obtained.

On the other hand, the air supplied into each of the living rooms 10, 11, 12, 13 is discharged from the outside to the corridor or the like through, for example, a gap at the lower end of the door or a space, and the suction grille 34 provided in the ceiling 16. Then, the air is taken into the exhaust fan 38.
The air taken into the suction grill 34 is removed of dust, dust, and the like by the filter of the suction grill 34, mixed with the air taken in from the outdoors, and recirculated to the indoor unit 31. . Further, the air taken in by the exhaust fan 38 is discharged to the outdoors.
As described above, the air conditioning system of the present embodiment can individually control the temperature of all living rooms 10, 11, 12, and 13 with one air conditioning unit 3, and has a floor heating effect in winter. It becomes.

  Next, with reference to the drawings, the structure of the double floor 2 serving as an air supply path constituting the air conditioning system of the present embodiment will be described in more detail with reference to FIGS.

  As described above, the double floor 2 of the present embodiment includes a floor foundation 20 such as a concrete slab, a plurality of support legs 21 arranged in parallel on the floor foundation 20 at an equal interval, and the plurality of support legs 21. The floor material 22 is provided on the floor, and the space under the floor is the air supply path 2a.

The plurality of support legs 21 include a support leg main body 21a for supporting the floor material 22, and the lower end of the support leg main body 21a is provided for sound insulation to the lower floor. In order to improve the standing state of 21a, a cone rubber 21b formed in a truncated cone shape or a truncated pyramid shape is provided.
Further, a pedestal 21d is provided between the upper surface of the support leg main body 21a and the floor material 22 for fixing them.

  In this embodiment, as shown in FIGS. 3 and 4 and FIGS. 6 and 7, auxiliary support legs are used together with the support legs 21. These auxiliary support legs are referred to as auxiliary support legs 21A and 21B in the present embodiment. The support legs 21 may be used instead of the auxiliary support legs 21A and 21B.

Further, as shown in FIGS. 3, 4, 6, and 7, a heat insulating material 20 a is laid on the upper surface of the floor base 20, and the heat insulating material 20 a passes through the air supply path 2 a. It is possible to prevent the heat of the air from escaping to the floor base 20 side. Thereby, it is possible to supply air to each of the living rooms 10, 11, 12, and 13 while reliably maintaining the temperature of the air conditioned by the air conditioning unit 3.
In addition, as described above, since the air can be supplied to the living rooms while reliably maintaining the temperature of the air-conditioned air, the temperature of the underfloor space can be maintained high. As a result, the height of the floor surface temperature of the room to be heated can be efficiently maintained, so that a high floor heating effect can be obtained and a more comfortable living environment can be formed.

In addition, as the heat insulating material 20a of this Embodiment, what is shown in FIG.3, FIG.4, FIG.6 and FIG. 7 is a resin fiber type | system | group and is a board-shaped heat insulating material, for example.
By the way, generally as a heat insulating material provided in the said site | part, the mat-like heat insulating material of glass wool fiber and the board-shaped heat insulating material of a resin foaming system are used. The former has the advantage of excellent workability because it is inexpensive and easy to adjust to the upper surface of the floor substrate 20, but the part located on the support leg of the double floor needs to be cut out in the field, and in that processing There was a problem that fiber dust was generated and remained in the underfloor space, and the fiber dust could flow into the room and scatter, which could lead to health hazards. The latter requires punching of the portion located on the support leg of the double floor, so that labor is required for the construction work of the heat insulating material 20a, and it is not easy to ensure the quality.
Accordingly, when the heat insulating material 20a is laid on the upper surface of the floor foundation 20, the size of the heat insulating material 20a is the same as that between the plurality of support legs 21, and is in close contact with the plurality of support legs 21. By laying the heat insulating material 20a, the above problem can be solved.

However, in the case of the resin fiber system and board-like heat insulating material 20a in the present embodiment, the heat insulating material 20a is placed in close contact with the plurality of support legs 21 between the plurality of support legs 21. When laid, the end of the heat insulating material 20a may float upward along the cone rubber 21b provided at the lower end of the support leg main body 21a. The path 2a may be blocked.
In such a case, it is desirable to attach a flange portion 21c for pressing the upper surface of the end portion of the heat insulating material 20a that is in close contact with the support leg main body 21a to the support leg main body 21a. Thus, when the plurality of heat insulating materials 20a are laid on the upper surface of the floor base 20, the end portions of the plurality of heat insulating materials 20a are simply inserted below the flange portions 21c of the plurality of support legs 21. Thus, it is only necessary to lay on the upper surface of the floor substrate 20. Further, in this way, by inserting the end portions of the plurality of heat insulating materials 20a below the flange portions 21c of the plurality of support legs 21, it can be laid on the upper surface of the floor substrate 20, The end portions of the plurality of heat insulating materials 20a do not need to be cut out in the field according to the shape of the plurality of support legs 21, and the plurality of heat insulating materials 20a are quickly laid on the upper surface of the floor substrate 20. be able to. In addition, since it is not necessary to perform notch processing on site, fiber dust of the heat insulating material 20a is not generated, and there is an effect that the heat insulating material 20a can be laid with high quality in a short construction period while keeping the underfloor space clean.
Furthermore, since the fiber dust of the heat insulating material 20a is not generated in this way, the fiber dust flows into the respective living rooms 10, 11, 12, and 13 and the health hazard due to the inhalation by the resident is ensured. Can be prevented.

On the other hand, as shown in FIGS. 6 and 7, the floor material 22 is laid on the base plate material 22a laid on the plurality of support legs 21, and on the upper surface of the base plate material 22a. A plurality of floor boards 22b joined together by actual rowing by the real part 23 and the concave female real part 24 are provided.
The plurality of floor board materials 22b are bonded to the base board material 22a by a thermoplastic resin adhesive such as hot melt.

Of the plurality of floor boards 22b, one floor board 22b laid along the walls (walls 10a, 11a, 12a, 13a) of the living rooms 10, 11, 12, 13 is the walls 10a, 11a. , 12a, and 13a are laid on the upper surface of the base plate 22a so that the male part 23 is located on the side opposite to the side located on the side.
And the other floor board material 22b adjacent to this one floor board material 22b cuts out the lower projection part 24b among the upper projection part 24a and the lower projection part 24b which form the female real part 24 of this other board material 22b. In this state, the base plate 22a is laid on the upper surface.
Therefore, a gap is formed below the protruding portion of the male part 23 of the one floor board material 22b, and in a portion where the lower protruding part 24b of the female part 24 of the other floor board material 22b is cut out. Become.

The floor board material 22b of the present embodiment is, for example, a long board formed in a rectangular shape, and the male part 23 is formed on one side surface along the length direction of the floor board material 22b. The female part 24 is formed on the other side, the male part 23 is formed on one side perpendicular to the length direction of the floor board 22b, and the female part is formed on the other side. 24 is formed.
That is, as described above, the other floor board material 22b adjacent to the one floor board material 22b is the lower projection of the upper projection part 24a and the lower projection part 24b that form the female part 24 of the other board material 22b. The portion 24b is notched and is laid on the upper surface of the base plate material 22a. The other floor plate material 22b adjacent to the one floor plate material 22b is the length direction of the one floor plate material 22b. And the floor board material 22b disposed adjacent to one side surface along the side surface and the floor board material 22b disposed adjacent to one side surface orthogonal to the length direction of the one floor board material 22b. .

Since such a gap becomes a movable range for the protruding portion 23a of the male part 23, when the one floor board material 22b is peeled from the base board material 22a, the one floor board material 22b is inclined. This makes it easier to remove the one floor board material 22b.
Further, since the plurality of floor board materials 22b are bonded to the base board material 22a by a thermoplastic resin adhesive, the thermoplastic resin adhesive is melted by heating from the surface of the floor board material 22b with electromagnetic energy or the like. By doing so, the floor board material 22b can be peeled from the base board material 22a without damaging both the base board material 22a and the floor board material 22b.
Thus, for example, when inspection, cleaning, repair, etc. of the underfloor space of the double floor 2 is necessary, the plurality of floor boards 22b can be reused, and further dust and the like can be removed during construction. Without generating, the floor plate material 22b can be peeled off from the base plate material 22a and the floor plate material 22b can be reconstructed.

Further, as shown in FIG. 7, the floor material 22 includes a side surface of the floor material 22 on the side of the walls 10 a, 11 a, 12 a, 13 a of the living room 10, 11, 12, 13, and the living room 10, 11. , 12 and 13 are laid on the plurality of support legs 21 so as to form a slight gap between the walls 10a, 11a, 12a and 13a.
As a result, vibrations and impact sounds of the flooring 22 are transmitted to the dwelling units on the other floors and adjacent dwelling units through the walls 10a, 11a, 12a, and 13a of the living rooms 10, 11, 12, and 13. Can be prevented.

Further, a baseboard 25 is attached to the walls 10a, 11a, 12a, 13a of the respective living rooms 10, 11, 12, 13 so as to form a slight gap with the one floor board material 22b. Yes.
Thus, this gap becomes a movable range for the one floor board material 22b. Accordingly, when the one floor board material 22b is peeled off from the base board material 22a, the one floor board material 22b can be inclined, so that the baseboard 25 is peeled off from the walls 10a, 11a, 12a and 13a. Even without this, it becomes easier to remove the one floor board material 22b.

  And in the lower end part of this baseboard 25, the clearance gap formed between the said flooring 22 and wall 10a, 11a, 12a, 13a of living room 10,11,12,13 and said one floor board material 22b And an airtight member 25a having elasticity are attached to both the gap formed between the double floor 2 and the living room 10, 11, 12, 13 from the underfloor space of the double floor 2. Air leakage of conditioned air can be prevented.

According to the present embodiment, the floor blowing unit 4, the damper unit 5, and the temperature controller 6 are provided in each living room 10, 11, 12, 13 in the building 1, thereby providing one air conditioning unit 3. Thus, all the living rooms 10, 11, 12, 13 can be individually set to arbitrary temperatures and arbitrarily air-conditioned, that is, multi-room control can be performed. In particular, since the opening / closing damper 5 can be opened and closed in multiple stages between the fully open state and the fully closed state by the temperature regulator 6, more precise temperature management is possible than in the prior art. .
In addition, when the opening / closing damper is controlled to open / close two positions as in the prior art, there is a time zone during which heating and supply to the underfloor space is not performed when the opening / closing damper is closed. By controlling the opening degree of the damper 5 in multiple stages between the fully open state and the fully closed state, the effect that the heating air is continuously supplied even with a small amount of air flow is created, and the temperature of the underfloor space is reduced. It became possible to keep it high. Thereby, since it becomes possible to maintain the floor surface temperature of the room 10, 11, 12, 13 used as heating object high, it becomes an air-conditioning system which can form the comfortable living environment where the high floor heating effect is acquired. Moreover, such a floor heating effect can be arbitrarily obtained in all the living rooms 10, 11, 12, and 13. Furthermore, this floor heating effect can be controlled for each room.
Further, by providing the damper unit 5 with the ventilation opening 52, the cooling / heating is stopped in all the living rooms 10, 11, 12, 13 or separately in the living rooms 10, 11, 12, 13 and the open / close damper 50 is closed. In addition, since a predetermined amount of air can be constantly supplied from the underfloor space to each of the rooms 10, 11, 12, and 13, connection with a 24-hour ventilation system is possible.
