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

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

The housing 61 has an air introduction port 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 introduction port 61A is arranged near the corner of the housing 61. The air introduction port 61A guides cold air or hot air via the air guiding duct 15 into the housing 61. The air introduction port 61A is exposed to the end surface 61a of the housing 61 orthogonal to the Y direction and the end surface 61b of the housing 61 orthogonal to the X direction. The end faces 61a and 61b are surfaces with which the damper 66 is in contact.
The air outlet 61B is formed so as to face the air introduction port 61A in the X direction.

The flow path forming members 63 to 65 are rectangular parallelepiped members that partition 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 in a state of being spaced apart in the X direction.

The flow path 68 has a bypass flow path 71 and a radiant air conditioning flow path 72.
The bypass flow path 71 is a flow path extending in the X direction, and communicates the air introduction port 61A and the air outlet port 61B. The bypass flow path 71 is a flow path through which cold air or hot air flows when cold air or hot air is not supplied to the radiant air conditioning flow path 72 (that is, when the radiant air conditioning flow path 72 is bypassed). Further, when the cold air or the hot air is supplied to the radiant air conditioning flow path 72, the cold air or the hot air is also supplied to a part of the bypass flow path 71.

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

The second flow path portions 72B to 72E are flow path portions extending in the Y direction. The second flow path portion 72B is formed between one side of the housing 61 in the X direction 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.
Of both ends of the second flow path portions 72B to 72E located in the Y direction, one end communicates with the first flow path portion 72A, and the other end communicates with the bypass flow path 71. is doing.

Since the radiant air-conditioning flow path 72 has the first and second flow path portions 72A to 72E having such a configuration, the radiant panel 52A allows cold air or hot air to flow through the radiant air-conditioning flow path 72. A part of the floor material 4 located above the above can be radiantly air-conditioned.

The damper 66 is housed in the housing 61 in a state where it can come into contact with the end faces 61a and 61b and can rotate in the C direction.
The damper 66 is electrically connected to the control device 28. The control device 28 controls to rotate each damper 66 so as to be in contact with one of the end faces 61a and 61b.
The damper 66 functions as a flow path switching unit for switching between supplying cold air or hot air only to the bypass flow path 71 or supplying cold air or hot air to the radiant air conditioning flow path 72.

As shown in FIG. 3, when the damper 66 is in contact with the end face 61a, the cold air or hot air introduced into the housing 61 passes only through the bypass flow path 71, and thus hardly contributes to radiant air conditioning.
On the other hand, in a state where the damper 66 is in contact with the end face 61b, the cold air or the hot air introduced into the housing 61 flows into the second flow path portion 72B. Therefore, the cold air or the hot air flows to the first flow path portion 72A and the second flow path portions 72C to 72E after passing through the second flow path portion 72B, which contributes to radiant air conditioning. Then, the cold air or hot air that contributed to the radiant air conditioning is derived from the air outlet 61B.

It is arranged so as to communicate with the air introduction port 61A of the radiant panel arranged (downstream side in the flow direction of cold air or hot air).

In this way, among the radiation panels 52A to 52D adjacent to each other in the X direction, the air outlet 61B of the radiation panel arranged in the front stage and the air introduction port 61A of the radiation panel arranged in the rear stage are communicated with each other. , The bypass flow path 71 constituting each radiation panel 52A to 52D can be communicated in the X direction.

The motion sensor 26 is fixed to the lower surface 6b 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 the position information when detecting which of the radiation panels 52A to 52P the person M is above.
As the human 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 FIGS. 1, 4, and 5. In FIG. 5, the same components as those of the structures shown in FIGS. 1 and 4 are designated by the same reference numerals.

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

The damper specifying unit 28B identifies the damper 66 of the radiation panel 52K, and inputs information about the specified damper 66 to the damper control unit 28C.
The damper control unit 28C controls a plurality of dampers 66 constituting the radiation panels 52A to 52P based on the information input from the damper specific unit 28B, so that only in the radiation air conditioning flow path 72 of the radiation panel 52K. While supplying cold air or hot air, the radiant air-conditioning flow path 72 of the radiant panels 52A to 52J and 52L to 52P other than the radiant panel 52K is bypassed.

Specifically, the damper control unit 28C controls to bring the damper 66 of the radiation panel 52K into contact with the end face 61b and to bring the damper 66 of the radiation panels 52A to 52J and 52L to 52P into contact with the end face 61a. ..

As a result, the cold air or hot air supplied into the radiating panels 52A to 52J, 52L to 52P flows only through the bypass flow path 71 of the radiating panels 52A to 52J, 52L to 52P, and thus the radiating panels 52A to 52J, 52L. It hardly contributes to the radiant air conditioning of the floor material 4 located above ~ 52P.
On the other hand, since cold air or hot air is supplied into the radiation air-conditioning flow path 72 of the radiation 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, a method of radiantly air-conditioning only a part of the floor material 4 by the pneumatic radiant air-conditioning system 10 will be described with reference to FIGS. 1 to 6.

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

Next, in S3, the damper 66 corresponding to the radiation panel 52K is specified by the damper specifying portion 28B.
Next, in S4, the damper control unit 28C controls the dampers 66 of the radiant panels 52A to 52P to supply cold air or hot air to the radiant air conditioning flow path 72 of the radiant panel 52K, and the other radiant panels 52A. The radiant air conditioning flow path 72 of ~ 52J, 52L ~ 52P is bypassed. At this time, the cold air or the hot air flows only through the bypass flow path 71 of the radiating 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 air-conditioned by the cold air or hot air supplied to the radiant air-conditioning flow path 72 of the radiant panel 52K.
For example, when cold air is supplied only to the radiant air-conditioning flow path 72 of the radiant panel 52K, the cold air cools only a part of the floor material 4, so that the radiant panel is compared with the cold 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 radiant air-conditioning flow path 72 of the radiant panel 52K, the hot air warms only a part of the floor material 4, so that it is compared with the warm air that warms the entire floor material 4. Therefore, the temperature drop when derived from the radiation panel 52K is small.
The cold air or hot air derived from the radiating panel 52K flows through the bypass flow path 71 of the radiating 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 cold air or hot 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 compared to the cold air cooling the entire floor material 4 or a hot air having a small temperature decrease compared to the hot air warming the entire floor material 4 is generated. Since it is blown out, the effect of convection air conditioning can be enhanced. After that, the process shown in FIG. 6 ends.

The process shown in FIG. 6 may be performed at the start of the cooling operation and the start of the heating operation.
By supplying cold air only to a part of the radiant panel 52K at the start of the cooling operation, it is possible to efficiently cool a part of the floor material 4 located above the part of the radiant panel 52K at an early stage from the start of the cooling operation. can.
Further, by supplying warm air only to a part of the radiant panel 52K at the start of the warm operation, a part of the floor material 4 located above the part of the radiant panel 52K can be efficiently used at an early stage from the start of the heating operation. Can be warmed up.

According to the pneumatic radiant air-conditioning system 10 of the present embodiment, cold air or temperature is applied only to the radiant air-conditioning flow path 72 of some of the radiant panels 52K among the plurality of radiant panels 52A to 52P based on the input information. By having the control device 28 for supplying wind, it is possible to radiate and air-condition only a part of the floor material 4 corresponding to a part of the radiation panel 52K, so that a part of the floor material 4 can be efficiently radiated and air-conditioned. can do.

Further, a radiation panel group composed of a plurality of radiation panels 52A to 52P provided on the lower surface 4b of the floor material 4 and arranged in series in a state of being in contact with each other in the X direction from the air guidance duct 15 side to the outlet 16A to the 16D side. 17A to 17D and a damper 66, which is controlled by the control device 28 and switches between supplying cold air or hot air only to the bypass flow path 71 or supplying cold air or hot air to the radiant air conditioning flow path 72. In addition, among the radiation panels 52A to 52P adjacent to each other in the X direction, the air outlet 61B of the radiation panel arranged in the front stage and the air introduction port 61A of the radiation panel arranged in the rear stage are communicated with each other. It is possible to communicate the bypass flow path 71 constituting each radiation panel in the X direction.

This makes it possible to make the plurality of bypass flow paths 71 arranged in the X direction function as bypass flow paths for bypassing the radiation panels 52A to 52P. Therefore, since it is not necessary to provide a bypass pipe 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, as an example, a case where cold air or hot air is supplied only to the radiant air-conditioning flow path 72 of the radiant panel 52K has been described as an example, but the radiant panel that supplies cold air or hot air is described. It can be changed as appropriate depending on the position of the person M.

Further, in the present embodiment, the case where cold air or hot air is supplied only to the radiant air-conditioning flow path 72 of one radiant panel 52K has been described as an example, but the number of radiant panels for supplying cold air or hot air has been described. Is not limited to one radiation panel as long as it is a part of all radiation panels 52A to 52P. For example, cold air or hot air may be supplied only to the radiant air-conditioning flow path 72 of the two radiant panels or only to the radiant air-conditioning flow path 72 of the three radiant panels.

Next, the pneumatic radiant air conditioning system 80 according to the modified example of the present embodiment will be described with reference to FIGS. 4 and 7 to 9.
In FIG. 7, the same components as those of the structure shown in FIG. 1 are designated by the same reference numerals. Further, in FIG. 8, the same components as those of the structures shown in FIGS. 5 and 7 are designated by the same reference numerals.

The pneumatic radiant air conditioning system 80 has a temperature sensor 81 instead of the human 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. Other than that, it is configured in the same manner as the pneumatic radiant air conditioning system 10.

The temperature sensor 81 is provided on the lower surface 6b of the ceiling 6. The temperature sensor 81 is electrically connected to the control device 28. The temperature sensor 81 detects the temperature of the entire surface of the floor 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 radiation panel specifying unit 28A selects a part of the radiation 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 portion 28A, and the temperature of the surface of the floor material 4 located above the radiant panels 52D, 52H, 52L, 52P arranged in the back of the room 7 is the surface of another region. When the temperature is lower than the temperature, the radiation panel specifying unit 28A identifies the radiation panels 52D, 52H, 52L, 52P as a part of the radiation panels.

Further, for example, a cooling operation signal is input to the radiation panel specifying portion 28A, and the temperature of the surface of the floor material 4 located above the radiation panels 52A, 52E, 52I, 52M arranged near the wall 2 is in another region. When the temperature is higher than the surface temperature of the above, the radiation panel specifying unit 28A identifies the radiation panels 52A, 52E, 52I, 52M as a part of the radiation panels.

Next, a method of radiantly air-conditioning only a part of the floor material 4 by the pneumatic radiant air-conditioning system 80 will be described with reference to FIGS. 4 and 9.
Here, as an example, the following description will be given by taking as an example a case where a heating operation signal is input to the radiation panel specifying unit 28A and the radiation panels 52D, 52H, 52L, 52P are specified as a part of the radiation panel. ..

First, when the process shown in FIG. 9 is started, the temperature sensor 81 detects the temperature of the entire surface of the floor material 4 in S7. 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, among the plurality of radiant panels 52A to 52P, as a part of the radiant panels, from the other region of the floor material 4. Also identifies the radiation panels 52D, 52H, 52L, 52P located below the region where the surface temperature is low.

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

Next, in S10, the damper control unit 28C brings the damper 66 corresponding to the radiation panels 52D, 52H, 52L, 52P into contact with the end face 61b, and the radiation panels 52A to 52C, 52E to 52G, 52I to 52K, 52M to The 52O and the end face 61a are brought into contact with each other.

Next, in S11, one of the floor materials 4 located above the radiant panels 52D, 52H, 52L, 52P by supplying warm air only to the radiant air conditioning flow path 72 of the radiant panels 52D, 52H, 52L, 52P. Radiate air conditioning the unit.
In this case as well, as in the case of using the pneumatic radiant air conditioning system 10 described above, warm air is supplied only to the radiant panels 52D, 52H, 52L, 52P among all the radiant panels 52A to 52P. A part of the floor material 4 can be efficiently radiated and air-conditioned.

Next, in S12, convection air conditioning is performed by blowing warm air that has passed through the radiation panels 52D, 52H, 52L, and 52P from 16A to 16D into the room 7.
At this time, as compared with the case where warm air is supplied to all the radiant panels 52A to 52P, the temperature drop of the warm air when derived from the radiant panels 52D, 52H, 52L, 52P is small, so that convection air conditioning is performed. It is possible to save energy in the pneumatic radiant air conditioning system 80 while enhancing the effect of the above.

As described above, the pneumatic radiant air conditioning system 80 can obtain the same effect as the pneumatic radiant air conditioning system 10 described above.
