<First embodiment>
Hereinafter, a radiation air-conditioning system according to a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a diagram illustrating an example of a schematic configuration of a radiant air conditioning system according to the first embodiment of the present invention.
The radiation air conditioning system 1 includes an air conditioner 2, radiation panel modules 10A, 10B,..., 10N, and pipes 8A, 8B,.
The radiant air conditioning system 1 is installed on the back side of the ceiling 9 of the indoor space 100 to be air conditioned, under the floor, in the wall surface, or the like. For example, the radiating surface of the radiating panel 19A included in the radiating panel module 10A is in contact with the space 100. Installed. The air conditioner 2 sucks the air in the space 100 from the suction port 3 and sends out the heat medium after the air conditioning. The heat medium of the present embodiment is air, and the air conditioner 2 sends out cold air or warm air. The sent heat medium is supplied to the radiation panel module 10A through the pipe 8A. In the radiant panel module 10A, the radiant panel is cooled or heated by the heat medium after air conditioning. Further, the heat medium that has passed through the radiant panel module 10A is supplied to the radiant panel module 10B via the pipe 8B, and similarly cools or heats the temperature of the radiant panel 19B. Similarly, after that, the heat medium is adjusted to the radiation panel module 10N that is disposed farthest from the air conditioner 2 while adjusting the temperature of the radiation panel 19n of each radiation panel module 10n (n = A to N) that passes therethrough. Supplied with. The heat medium that has cooled or heated the radiating panel 19N of the radiating panel module 10N is blown out to the space 100 from the outlet 4. As described above, in the radiant air conditioning system 1 of the present embodiment, the air-conditioned heat medium generated by the air conditioner 2 passes through the radiant panel module 10 </ b> A and the like disposed on the ceiling or the like. The radiation panel 19 is cooled or heated, and the temperature of the space 100 is adjusted by radiation from the radiation panel 19. Note that the number of the radiating panel modules 10A and the like arranged may be plural or one. The radiating panel modules 10A, 10B, etc. are collectively referred to as the radiating panel module 10, the pipes 8A, 8B, etc., and the piping 8, the radiating panels 19A, 19B, etc. are collectively referred to as the radiating panel 19.

FIG. 2 is a plan view showing an example of a schematic configuration of the radiation panel module according to the first embodiment of the present invention.
As shown in FIG. 2, the radiant panel module 10 is disposed on the damper 11, the flow path forming members 12 </ b> A, 12 </ b> B, 12 </ b> C, 12 </ b> D, 12 </ b> E, the open / close controller 13, the inlet 15, the outlet 16, and the bottom surface. The radiating panel 19 is provided. The damper 11 opens and closes within the range indicated by the arrow 11A. The opening / closing control unit 13 controls the opening / closing operation of the damper 11. When the damper 11 is in the position indicated by the solid line (set to the open state), the heat medium flowing in from the inlet portion 15 passes through the bypass flow path 18 in the direction indicated by the dashed arrow and is sent out from the outlet portion 16. On the other hand, when the damper 11 is in a position indicated by a broken line (controlled) by the control of the opening / closing control unit 13 (to be in a closed state), the heat medium flowing in from the inlet portion 15 causes the heat exchange channels 17A, 17B, It passes through 17C, 17D, 17E, 17F, and 17G and is sent out from the outlet portion 16.

Here, the heat exchange flow paths 17B, 17C, 17D, 17E, and 17F formed by the flow path forming members 12A, 12B, 12C, 12D, and 12E are formed to be narrower than the bypass flow path 18. Has been. Further, the heat exchange channels 17A and 17G may be formed wider than the heat exchange channels 17B and the like. As illustrated, the heat exchange channels 17B to 17F are provided so as to cross the radiation panel 19 in a direction perpendicular to the heat exchange channel 17G. With this configuration, the flow rate V ₁₇ of the heat medium that passes through the heat exchange channels 17B to 17F is faster than the flow rate V _{18 of the} heat medium that passes through the bypass channel 18. Hereinafter, the flow path forming member 12A and the like may be collectively referred to as the flow path forming member 12, the heat exchange flow path 17A and the like, and may be collectively referred to as the heat exchange flow path 17.

  In addition, the radiating panel module 10 is formed in a size that matches a size (for example, 600 mm × 600 mm, 600 mm × 1200 mm, etc.) of a ceiling board used for the system ceiling, for example. By modularizing in accordance with the standardized size, replacement with the ceiling board is facilitated, and the radiation air conditioning system 1 can be efficiently introduced.

FIG. 3 is a cross-sectional view showing an example of a schematic configuration of the radiation panel module according to the first embodiment of the present invention.
FIG. 3 is a cross-sectional view taken along line AA in the radiant panel module 10 of FIG. As shown in FIG. 3, the cross section of the radiation panel module 10 is L-shaped. As shown in the figure, the heat exchange flow path 17 and the bypass flow path 18 are formed on the back side of the radiation panel 19 (opposite the radiation surface). The height H1 of the bypass channel 18 is formed higher than the height H2 of the heat exchange channel 17G. Further, the width L1 is formed to have the same or larger width as the width L2. Therefore, the cross-sectional area of the bypass channel 18 is relatively large, and the cross-sectional area of the heat exchange channel 17G is relatively small. With this configuration, the flow rate V _{18 of the} heat medium flowing through the bypass flow path 18 is slow, and the flow speed V ₁₇ of the heat medium passing through the heat exchange flow path 17G is increased. The heat medium also flows at high speed in the heat exchange channels 17B, 17C, 17D, 17E, and 17F formed with narrow channel widths. When the heat medium flows at a high speed, heat transfer from the heat medium to the radiant panel 19 increases, and the temperature of the radiant panel 19 is strongly influenced by the temperature of the heat medium. Therefore, the temperature of the radiation panel 19 can be adjusted to a temperature suitable for the target temperature of the space 100 by passing the heat medium adjusted to a predetermined temperature by the air conditioner 2 through the heat exchange flow path 17. In order to increase heat transfer from the heat medium to the radiating panel 19, it is preferable to use a material having high thermal conductivity for the flow path forming member 12A and the like. Alternatively, the flow path forming member 12A or the like is molded from a resin or a foam material and combined with the radiation panel 19, thereby forming a flow path having the foam material as a side surface and the back side of the radiation panel 19 as a bottom surface. Also good. By setting it as such a structure, the heat exchange flow path 17 can be created only with two parts (The flow path formation member 12 shape | molded with the foaming material etc. and the radiation panel 19). By configuring the flow path in this manner, the temperature of the heat medium can be transmitted from the heat medium flowing at a relatively high speed to the radiation panel 19 directly or via the flow path forming member 12A or the like. it can. Further, as will be described later, the heat insulating material 14 may be arranged at the bottom of the bypass channel 18.
As described above, by using the flow path forming member 12A and the like, the flow path of the heat medium is formed in the structure of the parallel flow type heat exchanger, so that the heat transfer from the heat medium to the radiation panel 19 is efficiently performed. be able to.

  Based on the configuration shown in FIGS. 2 and 3, switching control of the damper 11 will be described. For example, when the radiant air conditioning system 1 performs a cooling operation, for a while after the operation is started, the amount of water vapor contained in the air present in the space 100 is large, and the radiant panel 19 is cooled in that state. Condensation may occur on the surface of the radiation panel 19. Therefore, in this embodiment, in an environment where condensation is likely to occur, “radiant air conditioning” by the radiating panel module 10 is not performed, but “convective air conditioning” is performed instead. Specifically, the opening / closing control unit 13 controls the damper 11 to be in an open state (solid line position), takes in the cold air generated by the air conditioner 2 from the inlet unit 15, passes through the bypass channel 18, and exits Send out from section 16. As illustrated in FIG. 1, the cold air that has passed through the bypass flow path 18 in each radiant panel module 10 is finally sent out from the outlet 6 to the space 100, convects the space 100, and is air-conditioned from the inlet 3. Returned to machine 2. Then, again, the heat medium cooled by the heat exchanger provided in the air conditioner 2 is supplied to the radiation panel module 10. As described with reference to FIGS. 2 and 3, since the cross-sectional area of the bypass flow path 18 is relatively large, the cooled heat medium passes through the bypass flow path 18 at a relatively slow speed. To do. Therefore, heat transfer from the heat medium to the radiant panel 19 while passing through the bypass channel 18 is reduced, and the radiant panel 19 is not cooled by the heat medium so that the temperature of the radiant panel 19 is kept relatively high. Be drunk. Therefore, the possibility that condensation occurs on the surface of the radiation panel 19 is reduced.

  In addition, as illustrated in FIG. 3, the radiating panel 19 can be more reliably prevented from being cooled by laying the heat insulating material 14 on the bottom of the bypass channel 18 (upper side of the radiating panel 19). Thereby, generation | occurrence | production of dew condensation can be prevented more effectively.

  As described above, when “convection air conditioning” in which the thermal refrigerant cooled by the air conditioner 2 is circulated in the space 100 while passing through the bypass channel 18, the air in the space 100 is removed by the dehumidifying function of the air conditioner 2. The amount of water vapor contained in is reduced. If the amount of water vapor is small, the possibility of condensation on the surface of the radiation panel 19 is low even if the radiation panel 19 is cooled and “radiation air conditioning” is performed. For example, when it becomes possible to determine that the operating environment has a low possibility of condensation from the measurement result of the humidity sensor provided in the air conditioner 2, the open / close control unit 13 controls the damper 11 to the closed state (broken line). . Then, heat transfer from the thermal refrigerant to the radiant panel 19 is promoted, and the radiant panel 19 is cooled by the heat medium and becomes a low temperature. Then, the temperature of the space 100 is air-conditioned by the radiation from the radiation panel 19 that has become low temperature. In this “radiant air conditioning”, water vapor in the air has been removed by “convection air conditioning” which has already been performed by passing the heat medium through the bypass flow path 18, so that the occurrence of condensation can be prevented.

Next, an example of the radiation air conditioning system 1 using a plurality of radiation panel modules 10 of the present embodiment will be described.
FIG. 4 is a diagram showing an example of the radiation air conditioning system in the first embodiment of the present invention.
As shown in the figure, the radiant air conditioning system 1 includes a plurality of radiant panel modules 10A ₁ , 10B ₁ ,..., 10N ₁ , 10A ₂ , 10B ₂ , ... 10N ₂ , 10A ₃ , 10B ₃ ,. , it is equipped with a 10N _3. The air conditioner 2 and the radiation panel modules 10A ₁ , 10A ₂ , 10A ₃ are connected via pipes 8P ₁ , 8P _{2 and the} like. The radiating panel modules 10 are also connected to each other by a pipe 8. For example, the radiation panel modules 10A ₁ and 10B ₁ are connected via the pipe 8B ₁ . Further, when a position close to the air conditioner 2 upstream and downstream of the furthest position, radiating panel module _{10 N} 1 most _{downstream, 10 N} 2, 10 N ₃ are respectively connected to outlet 4A, 4B, the 4C. The control device 30 is communicably connected to the air conditioner 2 and each open / close control unit 13A _{1 and the} like, and the control device 30 controls each open / close control unit 13A _{1 and the} like. Incidentally, it describes a damper 11 provided in the radiating panel module 10A ₁ and the damper 11A _1. The same applies to other configurations.

  As illustrated in FIG. 4, the suction port 3 and the plurality of outlets 4A, 4B, and 4C may be provided on a ceiling of an office or the like at a distance from each other, and the plurality of radiation panel modules 10 may be arranged side by side therebetween. In the case of such a configuration, for example, if the suction port 3 and the blowout port 4A are provided at positions close to both ends of a room to be air-conditioned, the entire room can be air-conditioned without any bias in convection air conditioning. Moreover, the modularized radiating panel module 10 can be arranged in series or in parallel by being connected via a pipe 8 which is a coupling member. Due to this property, the radiating panel modules 10 can be arranged side by side and arranged on the entire ceiling. Thereby, the whole room can be air-conditioned even in radiant air conditioning.

Further, for example, it is assumed that the user at the seat under the radiant panel module 10B2 feels cold during the cooling operation by the radiant air conditioner ₂ . In that case, the user can control the dampers 11B ₂ in the open state by inputting the instruction information to the switching control section 13B _2. Then, in the radiation panel module 10B _2, the heat medium passes through the bypass passage 18B _2, cold air of the heat medium is less likely to be transmitted to the radiation panel 19B _2. Then, the temperature of the radiation panel 19B ₂ is raised, the user will not feel the chill.

In general, when the same cooling temperature is set, the user is more likely to feel cool in “radiant air conditioning” than in “convection air conditioning”. By utilizing this property, for example, if only the user of the seat beneath the radiant panel module 10B ₂ are specially felt heat, the cooling operation without lowering the set temperature of the air conditioner 2 so performed. Then, the damper 11A ₁ and the like for radiating panel module 10A ₁ other than the radiation panel module 10B _2, respectively controlled in the open state, controls only the damper 11B ₂ radiating panel module 10B ₂ in the closed state. Then, only the lower radiating panel module 10B ₂ by "radiation air-conditioning", easier feel coolness, for other locations, by setting the temperature not so low to become the "convective air conditioning" is performed, the other Air conditioning can be performed at a temperature comfortable for the user.
Thus, according to the radiant panel module 10 of the present embodiment, which is configured as a module having a heat medium flow path and can switch the heat medium flow path between the bypass flow path 18 and the heat exchange flow path 17, Individual air conditioning that locally air-conditions only under 19 becomes possible.

The switching of the damper 11 is not limited to the control for switching between the complete open state and the closed state. For example, a stepping motor may be used so as to switch between an open state and a closed state in multiple stages. Thereby, the flow rate of the heat medium flowing into the heat exchange flow path 17 and the flow rate of the heat medium flowing into the bypass flow path 18 can be adjusted, and finer temperature control can be performed. For example, in the above example, when cold felt by the user at the bottom of the radiant panel module 10B ₂ is neither too, to control the position of the damper 11B2 to an intermediate position of the open and closed states. Then, since the small amount of heat medium than when closing control flows into the heat exchange passage 17 side, the temperature of the radiating panel 19B ₂ slightly increases, it is possible to soften is cold felt by the user.

Next, an example of the flow of switching control of the damper 11 will be described with reference to FIG. 5, taking the configuration of FIG. 4 as an example.
FIG. 5 is a flowchart showing an example of processing of the radiation air conditioning system in the first embodiment of the present invention.
As a premise, it is assumed that the user starts the cooling operation. First, the control device 30 measures an air state quantity in the space 100 (step S11). For example, the control apparatus 30 may acquire the measured value by the temperature sensor and humidity sensor with which the air conditioner 2 is provided. And the control apparatus 30 determines whether it is the conditions which the air of the space 100 condenses (step S12). For example, the control device 30 acquires a set temperature (a temperature specified by the user, for example, 20 ° C. to 25 ° C.) and humidity information of air sucked from the suction port 3 from the air conditioner 2, and is preset for each set temperature. Compare with the humidity threshold at which no condensation occurs. And if the present humidity is below a threshold value, the control apparatus 30 will determine with dew condensation. Further, if the current humidity exceeds the threshold value, the control device 30 determines that no condensation occurs. When it determines with dew condensation (step S12; Yes), the control apparatus 30 determines performing convection air conditioning in order to reduce the water vapor | steam of the space 100. FIG. Then, the control device 30 switches the heat medium flow path to the bypass flow path 18 (step S13). For example, the controller 30 transmits an instruction signal to control the damper 11A ₁ in the open state to the switching control section 13A _1. Controller 30 transmits the same command signal to the other switching control section 13A ₂ and the like. Switching control section 13A ₁ controls the damper 11A ₁ in the open state. The other open / close control unit 13A _{2 and the} like perform similar control. When the flow path is switched to the bypass flow path 18, the processing from step S11 is repeated again.

On the other hand, when it determines with no dew condensation (step S12; No), the control apparatus 30 switches the flow path of a heat medium to the heat exchange flow path 17 (step S14). For example, the control unit 30, a damper 11A ₁ sends an instruction signal to control the closed state to the switching control section 13A _1. Controller 30 transmits the same command signal to the other switching control section 13A ₂ and the like. Switching control section 13A ₁ controls the damper 11A ₁ in the closed state. The other open / close control unit 13A _{2 and the} like perform similar control. A method of switching the damper during cooling may be performed after a certain time from the start of operation without measuring the air state quantity.

  Next, the control device 30 determines whether or not to stop the cooling operation (step S15). For example, when a stop instruction is input from the user, the control device 30 determines to stop the cooling operation. If it is determined that the cooling operation is to be stopped (step S15; Yes), the control device 30 stops the operation of the air conditioner 2. When it determines with continuing cooling operation (step S15; No), the process from step S11 is repeated.

  Conventionally, a heat medium such as water (cold water or hot water) is supplied into a duct, and radiation air conditioning is often performed by a radiation panel that is indirectly cooled or heated by the heat. Such a method requires a dehumidification system for preventing condensation during cooling, and tends to be expensive. On the other hand, since the radiation panel module 10 of the present embodiment has means for switching between the dehumidifying operation and the radiation air conditioning by a damper, it can be handled by a single air conditioner, so that cost reduction can be realized. Moreover, according to this embodiment, regardless of heating and cooling, by having a radiation surface, it is possible to perform energy-saving and efficient radiation air-conditioning by sending out air close to the room temperature. Specifically, in the case of cooling, the air conditioner 2 may be operated at a higher set temperature. In the case of heating, the space 100 may be reduced even if the air conditioner 2 is operated at a lower set temperature. It can be air-conditioned to a desired temperature. Thereby, the cost reduction and energy saving of an air conditioning are realizable.

  In addition, by switching the damper 11 according to the indoor temperature and humidity, it is possible to realize comfortable radiant air conditioning while preventing condensation on the radiant panel 19.

Moreover, since the radiation panel module 10 is modularized and provided with a heat medium inlet / outlet port, the radiation panel module 10 can be freely radiated in accordance with the size and shape of the room by connecting using a coupling member such as the pipe 8. The panel 19 can be arrange | positioned and a desired range can be made into an air-conditioning object space.
For example, it is possible to arrange the radiating panel module 10 only at a specific position and not to arrange the entire room, but to set only a part of the space as an air-conditioning target.

  In addition, the radiant air-conditioning system 1 of the present embodiment can be introduced simply by replacing the ceiling board in the air-conditioning target range with the radiant panel module 10 using the existing air conditioner, the inlet, and the outlet as it is. The introduction cost can be reduced and the influence on the building can be reduced.

  In the above embodiment, cooling has been described as an example, but the same effect can be obtained in the case of heating operation. In the case of heating, it is more effective to arrange the radiating panel 19 on the floor surface. Moreover, by using air as the heat medium as described above, the radiation panel module 10 can be manufactured at a lower cost without taking measures such as water leakage, and can be used without worrying about water leakage. Although there is no limitation on the heat medium, water may be used.

Further, a damper 11 ′ is provided at a branch point between the pipe 8P ₁ ′ connected to the radiation panel module 10 ′ side and the bypass flow path 18 ′. The opening / closing operation of the damper 11 ′ is controlled by the control device 30. The control device 30 controls the air conditioner 2 and the damper 11 ′.

  The operation of the radiant air-conditioning system 1 ′ of this embodiment will be described with reference to the flowchart of FIG. First, it is assumed that the user starts the cooling operation. First, the control device 30 measures an air state quantity in the space 100 (step S11). And the control apparatus 30 determines whether it is conditions with high possibility that the air of the space 100 will dew condensation (step S12). When the possibility of dew condensation is high, the control device 30 switches the flow path of the heat medium to the bypass flow path 18 ′ in order to reduce the water vapor in the space 100 (step S13). Specifically, the control device 30 controls the damper 11 ′ to an open state (solid line position), and guides the heat medium (cold air) to the bypass flow path 18 ′. Then, in the case of this embodiment, a heat medium is not supplied to the radiation panel 19 '. In this case, cooling is performed not by radiant air conditioning but by convective air conditioning. Thereafter, the processing after step S11 is repeated. On the other hand, in the case where the air 100 in the space 100 has a low possibility of dew condensation, the control device 30 switches the flow path of the heat medium to the closed state (the position indicated by the broken line) (step S14). Then, the heat medium flows toward the radiating panel module 10 'and is supplied to each radiating panel module 10'. Then, the radiation panel 19 'is cooled, and the cooling operation by the radiation air conditioning is executed. Next, the control device 30 determines whether or not to stop the cooling operation (step S15). When the cooling operation is not stopped (step S15; No), the processes after step S11 are repeated.

  According to the radiation air-conditioning system 1 ′ of the present embodiment, in addition to the same effects as the first embodiment, by removing the damper 11 and the opening / closing control unit 13 from the radiation panel module 10 of the first embodiment, The system can be introduced at a lower cost.

<Third embodiment>

', An inlet portion 15 ″, an outlet portion 16 ″, and a radiating panel 19 ″ arranged on the bottom surface. The opening / closing control unit 13 ″ controls the opening / closing operation of the damper 11 ″. When the damper 11 ″ is in an open state (position indicated by a solid line), the heat medium flowing in from the inlet portion 15 ″ passes through the bypass flow path 18 ″ and is sent out from the outlet portion 16 ″. On the other hand, when the damper 11 ″ is in the closed state (position indicated by the broken line), the heat medium flowing in from the inlet portion 15 ″ passes through the heat exchange channel 17 ″ in the direction indicated by the solid line arrow, and the outlet portion. 16 ″ is sent out. The width of the heat exchange channel 17 '' is narrower than that of the bypass channel 18 '', and the height of the bypass channel 18 '' is the same as that illustrated in FIG. You may form higher than the height of the area | region currently formed. The flow rate of the heat medium passing through the heat exchange flow path 17 ″ is faster than the flow rate of the heat medium passing through the bypass flow path 18 ″, and a large amount of heat can be transferred to the radiating panel 19 ″. In addition, it is preferable to use a material with high thermal conductivity for the flow path forming member 12A ″, and use a material with low thermal conductivity for the wall surface of the bypass flow path 18 ″ and the like.

  According to the radiating panel module 10 ″ of this embodiment, the same effect as that of the first embodiment can be obtained. In addition, you may apply the structure of the heat exchange flow path 17 '' of this embodiment to the radiation panel module 10 'of 2nd embodiment.
