The control device 28 has a radiation panel specifying unit 28A, an on-off valve specifying unit 28B, and an on-off valve 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 FIGS. 1, 2, and 4, as an example, a radiant panel 17K) located below the person M based on the input position information. The radiant panel specifying unit 28A inputs information of the specified radiant panel 17K to the on-off valve specifying unit 28B.

The on-off valve specifying unit 28B specifies the on-off valve 24K provided in the first pipe 21K connected to the radiation panel 17K, and outputs information on the specified on-off valve 24K (information on the on-off valve 24K to be opened). It is input to the on-off valve control unit 28C.
The on-off valve control unit 28C opens the on-off valve 24K based on the information input from the on-off valve specifying unit 28B. Thus, of the plurality of radiating panels 17A to 17P, only the radiating panel 17K (a part of the radiating panels) is supplied with the cool air or the warm air.

  Next, with reference to FIGS. 1 to 4 and 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 regarding the position of the person M to the control device 28.
Next, in S2, the radiant panel specifying unit 28A specifies the radiant panel 17K located below the person M based on the input position information.

Next, in S5, a part of the floor material 4 located above the radiant panel 17K is radiated and air-conditioned by supplying cool air or hot air only to the radiant panel 17K.
For example, when the cool air is supplied only to the flow path 56 of the radiant panel 17K, the cool air cools only a part of the floor material 4 and is derived from the radiant panel 17K as compared with the cool air that has cooled the entire floor material 4. When the temperature rise is small.
Further, for example, when hot air is supplied only to the flow path 56 of the radiating panel 17K, the hot air heats only a part of the floor material 4 and is thus radiated compared with the warm air that heats the entire floor material 4. The temperature drop when derived from panel 17K is small.
The cool air or warm air derived from the radiation panel 17K is supplied to the outlet 16C by the second pipe 22K.

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 17K at the start of the cooling operation, it is possible to efficiently cool a part of the flooring material 4 located above the some of the radiating panels 17K 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 17K at the start of the warming operation, a part of the floor material 4 located above the some of the radiating panels 17K can be efficiently removed at an early stage from the start of the heating operation. Can be warmed.

By having the device 28, only a part of the floor material 4 corresponding to a part of the radiant panel 17K can be radiated and air-conditioned, so that a part of the floor material 4 can be radiated and air-conditioned efficiently.

  Also, by radiating air-conditioning only a part of the floor material 4, the temperature of the cool air blown into the room 7 from the outlet 16C rises or the temperature of the warm air lowers than when the entire floor material 4 is radiated and air-conditioned. Can be suppressed, so that the effect of the convection air conditioning can be enhanced, and the energy saving of the pneumatic radiant air conditioning system 10 can be achieved.

  In the first embodiment, as an example, a case in which only the radiating panel 17K is supplied with cold air or hot air has been described. However, the radiating panel that supplies cold air or hot air is located at a position where the person M is present. Can be changed as appropriate.

  Further, in the first embodiment, the case where cold air or hot air is supplied to only one radiating panel 17K has been described as an example. However, the number of radiating panels that supply cold air or hot air is The radiation panel may be a part of the panels 17A to 17P and is not limited to one radiation panel. For example, only two radiating panels or three radiating panels may be supplied with cool air or warm air.

Except for being different, it is configured similarly to the pneumatic radiant air conditioning system 10.

  The temperature sensor 61 is provided on the lower surface 6 b of the ceiling 6. The temperature sensor 61 is electrically connected to the control device 28. The temperature sensor 61 detects the temperature of the entire surface of the flooring material 4 and inputs the detected temperature information (information about the temperature distribution) to the radiation panel specifying unit 28A of the control device 28.

The radiant panel specifying unit 28A specifies a part of the radiant panels 17A to 17P based on the cooling operation signal or the heating operation signal and the temperature information from the temperature sensor 61.
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 17D, 17H, 17L, and 17P disposed in the back of the room 7 is changed to the surface of another area. When the temperature is lower than the temperature, the radiation panel specifying unit 28A specifies the radiation panels 17D, 17H, 17L, and 17P as some of the radiation panels.

  Further, 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 17A, 17E, 17I, and 17M arranged near the wall 2 is changed to 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 17A, 17E, 17I, and 17M as a part of the radiating panels.

  First, when the processing 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 61. The temperature sensor 61 inputs the detected temperature information (information on 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 61, as a part of the radiating panels of the plurality of radiating panels 17A to 17P, a part of the flooring 4 from other regions is used. Also specifies the radiating panels 17D, 17H, 17L, 17P disposed below the region where the surface temperature is low.

  Next, in S9, the on / off valve specifying unit 28B specifies the on / off valves 24D, 24H, 24L, 24P corresponding to the radiation panels 17D, 17H, 17L, 17P.

  Next, in S10, only the on-off valves 24D, 24H, 24L, and 24P are opened by the on-off valve control unit 28C, and the remaining on-off valves 24A to 24C, 24E to 24G, 24I to 24K, and 24M to 240 are closed. I do.

Next, in S11, only the radiant panels 17D, 17H, 17L, and 17P are supplied with warm air to partially radiate and air-condition the floor material 4 located above the radiant panels 17D, 17H, 17L, and 17P.
Also in this case, as in the first embodiment, the floor material 4 is used to supply hot air to only some of the radiating panels (radiating panels 17D, 17H, 17L, 17P) among all the radiating panels 17A to 17P. Can be efficiently radiated and air-conditioned.

Next, in S12, the convection air conditioning is performed by blowing the warm air that has passed through the radiation panels 17D, 17H, 17L, and 17P into the room 7 from 16A to 16D.
At this time, the temperature drop of the hot air derived from the radiating panels 17D, 17H, 17L, and 17P is smaller than that in the case where the hot air is supplied to all the radiating panels 17A to 17P. In addition to enhancing the effect of the above, energy saving of the pneumatic radiant air conditioning system 60 can be achieved.

  As described above, the pneumatic radiant air conditioning system 60 of the second embodiment can obtain the same effects as those of the pneumatic radiant air conditioning system 10 of the first embodiment.

  Note that the motion sensor 26 described in the first embodiment may be combined with the pneumatic radiant air conditioning system 60 of the second embodiment.

The pneumatic radiant air conditioning system 70 according to the third embodiment will be described with reference to FIGS. In FIG. 10, for convenience of description, a plurality of radiating panels 71A to 71P are illustrated in a cross-sectional view. The arrow shown in FIG. 10 indicates the direction (moving direction) in which the cool air or hot air flows. C shown in FIG. 11 indicates the rotation direction (C direction) of the damper 86. 10 and 11, the same components as those of the structure shown in FIG. 4 are denoted by the same reference numerals. 10 and 11, the same components are denoted by the same reference numerals.

  The pneumatic radiant air conditioning system 70 includes a plurality of radiant panels 17A to 17P, first pipes 21A to 21P, second pipes 22A to 22P, and an on-off valve that constitute the pneumatic radiant air conditioning system 10 of the first embodiment. It has the same configuration as the pneumatic radiant air conditioning system 10 except that it has a plurality of radiant panels 71A to 71P and pipes 73A to 73D and 75A to 75D instead of 24A to 24P.

The plurality of radiating panels 71A to 71P are radiating panels having the same configuration.
Here, the configuration of the radiating panels 71A to 71P will be described using the radiating panel 71A as an example (see FIG. 11).
The radiation panel 71 </ b> A has a housing 81, flow path forming members 83 to 85 that partition a flow path 88, and a damper 86. The housing 81 has a rectangular parallelepiped outer shape, and has a hollow portion inside.

The housing 81 has an air inlet 81A formed on one side in the X direction and an air outlet 81B formed on the other side in the X direction.
The air inlet 81 </ b> A is arranged near a corner of the housing 81. The air inlet 81 </ b> A guides cool air or warm air through the air guide duct 15 into the housing 81. The air inlet 81A is exposed at an end face 81a of the housing 81 orthogonal to the Y direction and at an end face 81b of the housing 81 orthogonal to the X direction. The end surfaces 81a and 81b are surfaces on which the damper 86 abuts.
The air outlet 81B is formed to face the air inlet 81A in the X direction.

The flow path forming members 83 to 85 are rectangular parallelepiped members that define the flow path 88 in the housing 81, and are housed in the housing 81. The flow path forming members 83 to 85 are arranged at intervals in the X direction.
The flow channel 88 has flow channel portions 88A and 88B extending in the X direction and flow channel portions 88C to 88F extending in the Y direction. The flow path portion 88A extends in the X direction and connects the air inlet 81A and the air outlet 81B.

The damper 86 is accommodated in the housing 81 so as to be able to contact the end faces 81a and 81b and to be rotatable in the C direction.
Each damper 86 provided on the radiation panels 71A to 71P is electrically connected to the control device 28. The control device 28 controls the rotation of each damper 86 so as to be in contact with one of the end surfaces 81a and 81b. The damper 86 is a mechanism for selecting whether or not to bypass the flow passage portions 88B to 88F.

As shown in FIG. 11, when the damper 86 is in contact with the end face 81a, the cool air or hot air introduced into the housing 81 passes through only the flow path portion 88A, and thus hardly contributes to the radiation air conditioning.
On the other hand, when the damper 86 is in contact with the end face 81b, the cool air or the warm air introduced into the housing 81 flows to the flow path 88C. Therefore, the cold air or the hot air flows through the flow passages 88A, 88B, 88D to 88F after passing through the flow passage 88C, and thus contributes to radiation air conditioning. Then, the cool air or warm air that has contributed to the radiation air conditioning is led out from the air outlet 81B.

The radiating panels 71A to 71D are arranged in series in the order of the radiating panel 71A, the radiating panel 71B, the radiating panel 71C, and the radiating panel 71D so as to be in contact with the air guide duct 15 and the direction toward the outlet 16A. .
The air outlet 81B of the radiant panel 71A faces and communicates with the air inlet 81A of the radiant panel 71B in the X direction. The air outlet 81B of the radiant panel 71B faces and communicates with the air inlet 81A of the radiant panel 71C in the X direction. The air outlet 81B of the radiant panel 71C faces and communicates with the air inlet 81A of the radiant panel 71D in the X direction.

The radiating panels 71E to 71H are arranged in series in the order of the radiating panel 71E, the radiating panel 71F, the radiating panel 71G, and the radiating panel 71H so as to be in contact with the air guide duct 15 and the direction toward the outlet 16B. .
The air outlet 81B of the radiant panel 71E faces and communicates with the air inlet 81A of the radiant panel 71F in the X direction. The air outlet 81B of the radiant panel 71F faces and communicates with the air inlet 81A of the radiant panel 71G in the X direction. The air outlet 81B of the radiant panel 71G faces and communicates with the air inlet 81A of the radiant panel 71H in the X direction.

The radiating panels 71I to 71L are arranged in series in the order of the radiating panel 71I, the radiating panel 71J, the radiating panel 71K, and the radiating panel 71L so as to be in contact with the air guiding duct 15 and the direction toward the outlet 16C. .
The air outlet 81B of the radiant panel 71I faces and communicates with the air inlet 81A of the radiant panel 71J in the X direction. The air outlet 81B of the radiant panel 71J faces and communicates with the air inlet 81A of the radiant panel 71K in the X direction. The air outlet 81B of the radiant panel 71K faces and communicates with the air inlet 81A of the radiant panel 71L in the X direction.

The radiating panels 71M to 71P are arranged in series in the order of the radiating panel 71M, the radiating panel 71N, the radiating panel 71O, and the radiating panel 71P so as to be in contact with the air guide duct 15 and the outlet 16D. .
The air outlet 81B of the radiant panel 71M faces and communicates with the air inlet 81A of the radiant panel 71N in the X direction. The air outlet 81B of the radiant panel 71N faces and communicates with the air inlet 81A of the radiant panel 71O in the X direction. The air outlet 81B of the radiant panel 71O faces and communicates with the air inlet 81A of the radiant panel 71P in the X direction.

  By arranging the radiating panels 71A to 71P so that the air inlet 81A and the air outlet 81B of the radiating panel adjacent to each other in the X direction communicate with each other in this way, it is not necessary to separately provide a pipe. Thereby, the configuration of the pneumatic radiant air conditioning system 70 can be simplified as compared to the pneumatic radiant air conditioning system 10 of the first embodiment.

  In addition, the flow path portion 88A formed in the radiation panels 71A to 71P functions as a bypass flow path that bypasses the flow path portions 88B to 88F formed in the radiation panels 71A to 71P. Thereby, since it is not necessary to separately prepare a pipe for bypass, the configuration of the pneumatic radiant air conditioning system 70 can be simplified.

  According to the pneumatic radiant air conditioning system 70 of the third embodiment, the radiant panels 71A to 71P are arranged such that the air inlet 81A and the air outlet 81B of the radiant panel adjacent to each other in the X direction communicate with each other. Thus, after simplifying the configuration of the pneumatic radiant air conditioning system 70, only a part of the floor material can be radiated and air-conditioned, and the effect of convective air-conditioning can be enhanced to save energy.
