JP-A-2004-232929

By the way, in the pneumatic radiant air-conditioning system disclosed in Patent Literature 1, the entire panel board can be radiated and air-conditioned because cold or hot air is supplied to the entire ventilation space formed between the panel board and the slab. However, it was difficult to radiate air-condition only part of the panel board (floor material).
When only part of the panel board (floor material) is radiated and air-conditioned, it is preferable that the number of components constituting the pneumatic radiant air-conditioning system is small from the viewpoint of cost.

  Therefore, an object of the present invention is to provide an air-type radiant air-conditioning system capable of radiating and air-conditioning only a part of the floor material while reducing the number of components of the air-type radiant air-conditioning system.

The air outlet of the arranged radiant panel communicates with the air inlet of the radiant panel arranged at the subsequent stage.

  According to the present invention, based on the input information, the floor has a control device that supplies cold air or hot air only to the radiating air conditioning passages of some of the radiating panels based on the input information. Radiation air conditioning can be performed only on a part of the floor material, so that a part of the floor material can be efficiently radiated air-conditioned.

The lower end 15 </ b> B of the air guide duct 15 is disposed below the flooring 4. The lower end 15B of the air guide duct 15 is connected to one ends of the first pipes 21A to 21D. Thus, the first pipes 21A to 21D are supplied with the cool air or the hot air that has passed through the air guide duct 15.
A portion of the air guide duct 15 disposed between the ceiling 6 and the floor member 4 extends in the Z direction.

  The outlets 16 </ b> A to 16 </ b> D are formed in the floor member 4 located near the wall 3. The outlets 16 </ b> A to 16 </ b> D are openings each having a rectangular shape in a plan view. The outlets 16A to 16D are arranged in the order of the outlet 16A, the outlet 16B, the outlet 16C, and the outlet 16D in the Y direction.

  The radiant panel groups 17A to 17D are configured to have four radiant panels (a plurality of radiant panels) among the radiant panels 52A to 52P. The radiating panels 52A to 52P are radiating panels having the same configuration.

Here, before describing the radiating panel groups 17A to 17D in detail, the configuration of the radiating panels 52A to 52P will be described using the radiating panel 52A as an example (see FIG. 3).
The radiating panel 52A includes a housing 61, flow path forming members 63 to 65 that divide the flow path 68, and a damper 66 (flow path switching unit). The housing 61 has a rectangular parallelepiped outer shape, and has a hollow portion inside.

The housing 61 has an air inlet 61A formed on one side in the X direction and an air outlet 61B formed on the other side in the X direction.
The air inlet 61 </ b> A is disposed near a corner of the housing 61. The air inlet 61 </ b> A guides cool air or warm air through the air guide duct 15 into the housing 61. The air inlet 61A is exposed at an end face 61a of the housing 61 orthogonal to the Y direction and at an end face 61b of the housing 61 orthogonal to the X direction. The end surfaces 61a and 61b are surfaces on which the damper 66 abuts.
The air outlet 61B is formed to face the air inlet 61A in the X direction.

  The flow path forming members 63 to 65 are rectangular parallelepiped members that define the flow path 68 in the housing 61, and are housed in the housing 61. The flow path forming members 63 to 65 are arranged at intervals in the X direction.

The flow channel 68 has a bypass flow channel 71 and a radiation air conditioning flow channel 72.
The bypass passage 71 is a passage extending in the X direction, and communicates the air inlet 61A and the air outlet 61B. The bypass flow path 71 is a flow path through which cool air or hot air flows when no cool air or hot air is supplied to the radiation air conditioning flow path 72 (that is, when the radiation air conditioning flow path 72 is bypassed). When supplying cool air or hot air to the radiating air conditioning flow path 72, cool air or hot air is also supplied to a part of the bypass flow path 71.

The radiation air conditioning flow path 72 is a flow path having a flow path longer than the bypass flow path 71. The radiation air conditioning flow channel 72 has a first flow channel portion 72A and second flow channel portions 72B to 72E (a plurality of second flow channel portions).
The first flow path portion 72A faces the bypass flow path 71 across the flow path forming members 63 to 65 in the Y direction.

The second flow paths 72B to 72E are flow paths extending in the Y direction. The second flow path portion 72B is formed between one side in the X direction of the housing 61 and the flow path forming member 63. The second flow path portion 72C is formed between the flow path forming member 63 and the flow path forming member 64.
The second flow path portion 72D is formed between the flow path forming member 64 and the flow path forming member 65. The second flow path portion 72E is formed between the flow path forming member 65 and the other side of the housing 61 in the X direction.
One end of the two end portions of the second flow passage portions 72B to 72E located in the Y direction communicates with the first flow passage portion 72A, and the other end communicates with the bypass flow passage 71. are doing.

  Since the radiation air conditioning flow path 72 has the first and second flow path portions 72A to 72E having such a configuration, the cool air or the hot air is caused to flow through the radiation air conditioning flow path 72, and thus the radiation panel 52A is formed. Radiant air conditioning can be performed on a part of the flooring material 4 located above the floor material 4.

The damper 66 is housed in the housing 61 so as to be able to contact the end surfaces 61a and 61b and to be rotatable in the C direction.
The damper 66 is electrically connected to the control device 28. The control device 28 controls the rotation of each damper 66 so as to contact one of the end surfaces 61a and 61b.
The damper 66 functions as a flow path switching unit that switches between supplying cool air or hot air only to the bypass flow path 71 and supplying cool air or hot air to the radiation air conditioning flow path 72.

As shown in FIG. 3, in a state where the damper 66 is in contact with the end face 61a, the cool air or the warm air introduced into the housing 61 passes through only the bypass flow path 71, and thus hardly contributes to the radiation air conditioning.
On the other hand, when the damper 66 is in contact with the end surface 61b, the cool air or the warm air introduced into the housing 61 flows to the second flow path 72B. Therefore, the cold air or the hot air flows through the second flow path 72B and then flows into the first flow path 72A and the second flow paths 72C to 72E, thereby contributing to radiant air conditioning. Then, the cool air or warm air that has contributed to the radiation air conditioning is led out from the air outlet 61B.

Next, the radiation panel groups 17A to 17D will be sequentially described.
The radiant panel group 17A has radiant panels 52A to 52D (a plurality of radiant panels) that come into contact with the lower surface 4b of the flooring material 4. The upper surfaces of the radiation panels 52A to 52D are in contact with the lower surface 4b of the flooring material 4, respectively.
The radiating panels 52A to 52D are arranged in series in the order of the radiating panel 52A, the radiating panel 52B, the radiating panel 52C, and the radiating panel 52D so as to be in contact with each other in the X direction from the air guiding duct 15 side toward the outlet 16A. I have.

  Further, the radiation panels 52A to 52D are arranged such that, of the radiation panels 52A to 52D adjacent to each other in the X direction, the air outlet 61B of the radiation panel arranged at the front stage (upstream side in the flow direction of the cold air or the hot air) and the rear stage. (The downstream side in the flow direction of the cool air or the hot air) is arranged so as to communicate with the air inlet 61A of the radiant panel arranged.

  As described above, in the X direction, of the radiation panels 52A to 52D adjacent to each other, the air outlet 61B of the radiation panel arranged at the front stage and the air inlet 61A of the radiation panel arranged at the subsequent stage communicate with each other. In the X direction, it is possible to make the bypass flow paths 71 constituting each of the radiation panels 52A to 52D communicate with each other.

Thereby, a plurality of bypass passages 71 (in FIG. 4, for example, four bypass passages) arranged in the X direction are used to bypass the radiant air conditioning passages 72 of each of the radiant panels 52A to 52E. It becomes possible to function as a channel for use.
Therefore, since there is no need to provide bypass piping for each of the radiant panels 52A to 52D, the number of components of the pneumatic radiant air conditioning system 10 can be reduced.

The radiant panel group 17B has radiant panels 52E to 52H that come into contact with the lower surface 4b of the flooring material 4. The upper surfaces of the radiating panels 52E to 52H are in contact with the lower surface 4b of the flooring material 4, respectively.

  In the radiating panels 52I to 52L, among the radiating panels adjacent to each other in the X direction, the air outlet 61B of the radiating panel arranged at the front stage and the air inlet 61A of the radiating panel arranged at the subsequent stage communicate with each other. Are arranged as follows.

The radiant panel group 17D has radiant panels 52M to 52P that come into contact with the lower surface 4b of the flooring material 4. The upper surface of the radiation panel 52 is in contact with the lower surface 4b of the flooring material 4, respectively. The radiating panel group 17D is arranged on one side in the Y direction of the radiating panel group 17C.

Are arranged as follows.

  As described above, by arranging the radiating panel groups 17A to 17D in the Y direction orthogonal to the X direction, the radiating panels 52A to 52P can be arranged in a wide area. Thereby, even when the area of the upper surface 4a of the flooring material 4 is large, only a part of the flooring material 4 can be radiated and air-conditioned.

The human sensor 26 is fixed to the lower surface 6 b of the ceiling 6. The motion sensor 26 is electrically connected to the control device 28. The motion sensor 26 inputs to the control device 28 positional information when detecting the position of the person M above any of the radiation panels 52A to 52P.
As the motion sensor 26, for example, an image sensor (camera), an ultrasonic sensor, a floor sensor, or the like can be used.

  Next, the control device 28 will be described with reference to FIG. 1, FIG. 4, and FIG. 5, the same components as those of the structure shown in FIGS. 1 and 4 are denoted by the same reference numerals.

The control device 28 has a radiation panel specifying unit 28A, a damper specifying unit 28B, and a damper control unit 28C.
The position information from the human sensor 26 is input to the radiation panel identification unit 28A.
The radiant panel specifying unit 28A specifies a radiant panel (in the case of FIG. 1, as an example, a radiant panel 52K) located below the person M based on the input position information. The radiant panel specifying unit 28A inputs information of the specified radiant panel (in the case of FIG. 1, as an example, the radiant panel 52K) to the damper specifying unit 28B.

The damper specifying unit 28B specifies the damper 66 of the radiation panel 52K, and inputs information on the specified damper 66 to the damper control unit 28C.
The damper control unit 28C controls the plurality of dampers 66 constituting the radiating panels 52A to 52P based on the information input from the damper specifying unit 28B, so that only the radiating air conditioning flow path 72 of the radiating panel 52K is provided. The cooling air or the hot air is supplied, and the radiation air conditioning flow paths 72 of the radiation panels 52A to 52J and 52L to 52P other than the radiation panel 52K are bypassed.

  Specifically, the damper control unit 28C controls the damper 66 of the radiant panel 52K to abut on the end face 61b, and controls the damper 66 of the radiant panels 52A to 52J and 52L to 52P to abut on the end face 61a. .

Thereby, the cool air or warm air supplied into the radiant panels 52A to 52J and 52L to 52P flows only through the bypass channel 71 of the radiant panels 52A to 52J and 52L to 52P, and thus the radiant panels 52A to 52J and 52L. It hardly contributes to the radiant air conditioning of the flooring material 4 located above ５２52P.
On the other hand, since the cool air or the hot air is supplied into the radiant air conditioning flow path 72 of the radiant panel 52K located below the person M, a part of the floor material 4 located below the person M is radiated and air-conditioned. be able to.

  Next, with reference to FIGS. 1 to 6, a method of radiating and air-conditioning only a part of the floor material 4 by the pneumatic radiant air-conditioning system 10 will be described.

First, when the process shown in FIG. 6 is started, the position of the person M is detected by the human sensor 26 in S1. The human sensor 26 inputs position information on the position of the person M to the radiation panel specifying unit 28A of the control device 28.
Next, in S2, the radiant panel specifying unit 28A specifies the radiant panel 52K located below the person M based on the input position information.

Next, in S3, the damper 66 corresponding to the radiation panel 52K is specified by the damper specifying unit 28B.
Next, in S4, by controlling the dampers 66 of the radiating panels 52A to 52P by the damper control unit 28C, cool air or hot air is supplied to the radiating air-conditioning flow path 72 of the radiating panel 52K, and the other radiating panels 52A are controlled. To 52J and 52L to 52P are bypassed. At this time, the cool air or the warm air flows only through the bypass passage 71 of the radiation panels 52A to 52J and 52L to 52P.

Next, in S5, a part of the floor material 4 located above the radiant panel 52K is radiated and conditioned by the cool air or the hot air supplied to the radiant air conditioning flow channel 72 of the radiant panel 52K.
For example, when the cool air is supplied only to the radiating air-conditioning flow path 72 of the radiant panel 52K, the cool air cools only a part of the floor material 4, so that the cool air is cooled compared to the cool air that cools the entire floor material 4. The temperature rise when derived from 52K is small.
Further, for example, when hot air is supplied only to the radiating air-conditioning flow path 72 of the radiant panel 52K, the hot air heats only a part of the floor material 4 and thus is compared with the warm air that warms the entire floor material 4. As a result, the temperature drop when derived from the radiation panel 52K is small.
The cool air or warm air derived from the radiation panel 52K flows through the bypass channel 71 of the radiation panel 52L, and is then supplied to the outlet 16C via the second pipe 22C.

Next, in S6, convection air conditioning is performed by the cool air or the warm air blown into the room 7 from the outlet 16C.
At this time, in the room 7, a cold air having a small temperature rise as compared with the cold air that has cooled the entire flooring material 4, or a warm air having a small temperature decrease as compared with the warm air having heated the entire flooring material 4. Since the air is blown out, the effect of convection air conditioning can be enhanced. Thereafter, the process illustrated in FIG. 6 ends.

The process shown in FIG. 6 may be performed at the start of the cooling operation and at the start of the heating operation.
By supplying the cool air to only some of the radiating panels 52K at the start of the cooling operation, it is possible to efficiently cool a part of the flooring material 4 located above some of the radiating panels 52K at an early stage from the start of the cooling operation. it can.
In addition, by supplying warm air to only some of the radiating panels 52K at the start of the warming operation, a part of the flooring material 4 located above some of the radiating panels 52K can be efficiently removed at an early stage from the start of the heating operation. Can be warmed.

  According to the pneumatic radiant air conditioning system 10 of the present embodiment, based on the input information, only the radiant air conditioning flow channels 72 of some of the radiant panels 52K out of the plurality of radiant panels 52A to 52P have the cool air or the hot air. By having the control device 28 for supplying the wind, only a part of the floor material 4 corresponding to a part of the radiant panels 52K can be radiated and air-conditioned. can do.

  Further, a radiating panel group including a plurality of radiating panels 52A to 52P provided on the lower surface 4b of the flooring material 4 and arranged in series in contact with each other in the X direction from the air guiding duct 15 to the outlet 16A to the 16D side. 17A to 17D and a damper 66 controlled by the control device 28 to switch between supplying cool air or hot air only to the bypass flow path 71 or supplying cool air or hot air to the radiant air conditioning flow path 72. In addition, in the X direction, among the radiation panels 52A to 52P adjacent to each other, by communicating the air outlet 61B of the radiation panel arranged at the front stage and the air inlet 61A of the radiation panel arranged at the rear stage, In the X direction, it is possible to communicate the bypass flow paths 71 constituting each radiation panel.

  This makes it possible to cause the plurality of bypass channels 71 arranged in the X direction to function as bypass channels for bypassing the radiation panels 52A to 52P. Therefore, since there is no need to provide bypass piping for each of the radiant panels 52A to 52P, the number of components of the pneumatic radiant air conditioning system 10 can be reduced.

  In the present embodiment, an example has been described in which the cool air or the hot air is supplied only to the radiating air-conditioning flow path 72 of the radiant panel 52K. However, the radiant panel that supplies the cool air or the hot air is: It can be appropriately changed depending on the position where the person M is.

  Further, in the present embodiment, an example has been described in which the cool air or the hot air is supplied only to the radiant air conditioning flow path 72 of one radiant panel 52K, but the number of the radiant panels that supply the cool air or the hot air is described. Is only required to be a part of the radiating panels of all the radiating panels 52A to 52P, and is not limited to one radiating panel. For example, only the radiant air conditioning flow path 72 of two radiant panels or only the radiant air conditioning flow path 72 of three radiant panels may be supplied with cool air or hot air.

Next, a pneumatic radiant air conditioning system 80 according to a modified example of the present embodiment will be described with reference to FIGS. 4 and 7 to 9.

  The pneumatic radiant air conditioning system 80 has a temperature sensor 81 instead of the motion sensor 26 constituting the pneumatic radiant air conditioning system 10 of the present embodiment, and the processing performed by the radiant panel specifying unit 28A of the control device 28 is different. Except for this, the configuration is the same as that of the pneumatic radiation air conditioning system 10.

  The temperature sensor 81 is provided on the lower surface 6 b of the ceiling 6. Temperature sensor 81 is electrically connected to control device 28. The temperature sensor 81 detects the temperature of the entire surface of the flooring material 4 and inputs the detected temperature information (information on the temperature distribution) to the radiation panel specifying unit 28A of the control device 28.

The radiant panel specifying unit 28A determines a part of the radiant panels 52A to 52P (see FIG. 4) based on the cooling operation signal or the heating operation signal and the temperature information from the temperature sensor 81. Identify.
For example, a heating operation signal is input to the radiant panel specifying unit 28A, and the temperature of the surface of the flooring material 4 located above the radiant panels 52D, 52H, 52L, and 52P disposed in the back of the room 7 is the surface of another area. When the temperature is lower than the temperature, the radiation panel specifying unit 28A specifies the radiation panels 52D, 52H, 52L, and 52P as some of the radiation panels.

  In addition, for example, a cooling operation signal is input to the radiant panel specifying unit 28A, and the temperature of the surface of the flooring material 4 located above the radiant panels 52A, 52E, 52I, and 52M arranged near the wall 2 is in another area. When the temperature is higher than the surface temperature of the radiating panel, the radiating panel specifying unit 28A specifies the radiating panels 52A, 52E, 52I, and 52M as some of the radiating panels.

  First, when the process shown in FIG. 9 is started, in S7, the temperature of the entire surface of the flooring material 4 is detected by the temperature sensor 81. The temperature sensor 81 inputs the detected temperature information (information about the temperature distribution) to the control device 28.

  Next, in S8, based on the heating operation signal and the temperature information from the temperature sensor 81, a part of the plurality of radiant panels 52A to 52P is used as a part of the radiant panels from the other area of the flooring material 4. Also specifies the radiating panels 52D, 52H, 52L, 52P arranged below the region where the surface temperature is low.

  Next, in S9, the dampers 66 (four dampers 66) corresponding to the radiating panels 52D, 52H, 52L, 52P are specified by the damper specifying unit 28B.

  Next, in S10, the damper control unit 28C causes the dampers 66 corresponding to the radiating panels 52D, 52H, 52L, and 52P to come into contact with the end face 61b, and radiates panels 52A to 52C, 52E to 52G, 521 to 52K, and 52M to 52O is brought into contact with the end face 61a.

Next, in S11, by supplying warm air only to the radiation air conditioning flow path 72 of the radiation panels 52D, 52H, 52L, and 52P, one of the floor materials 4 located above the radiation panels 52D, 52H, 52L, and 52P is supplied. Radiant air conditioning of the part.
Also in this case, as in the case of using the air-type radiation air conditioning system 10 described above, of all the radiation panels 52A to 52P, only the radiation panels 52D, 52H, 52L, and 52P are supplied with warm air. A part of the floor material 4 can be efficiently radiated and air-conditioned.

Next, in S12, convection air conditioning is performed by blowing the warm air that has passed through the radiation panels 52D, 52H, 52L, and 52P into the room 7 from 16A to 16D.
At this time, the temperature drop of the hot air derived from the radiating panels 52D, 52H, 52L, and 52P is smaller than that in the case where the hot air is supplied to all the radiating panels 52A to 52P. , The energy of the pneumatic radiant air conditioning system 80 can be reduced.

  As described above, the pneumatic radiant air conditioning system 80 can achieve the same effects as those of the pneumatic radiant air conditioning system 10 described above.
