<Embodiment>
Hereinafter, the air conditioning system of the present embodiment will be described with reference to the drawings.
FIG. 1 is a schematic diagram illustrating an example of an air conditioning system according to an embodiment of the present invention.
The air conditioning system 100 includes an indoor unit 10, an outdoor unit 20, radiation panel modules 40A and 40B, and a duct 13. Hereinafter, the radiation panel modules 40A, 40B and the like may be collectively referred to as the radiation panel module 40.
The indoor unit 10 is installed at the back of the ceiling of the space W0 in the room to be air-conditioned, sucks the air W in the space W0 from the suction port W1, adjusts the air W to an appropriate temperature, and sends the air W to the duct 13. . At least one radiant panel module 40 is arranged on a floor, a wall surface, a ceiling, or the like of the space W0, and the temperature-controlled air sent to the duct 13 is supplied to the radiant panel module 40. The radiant panel module 40 includes a radiant panel that radiates radiation heat to the space W0, and an air passage through which the air W supplied from the indoor unit 10 passes. The radiating panel is arranged on a surface such as a floor, a wall, or a ceiling such that the radiating surface (radiating panel) faces the space W0 side so as to be in contact with the space W0, and the temperature-controlled air W passing through the back surface of the radiating panel is provided. Cool or heat the radiant panel. When the radiant panel is cooled or heated, the radiant heat is transmitted to the space W0 via the radiant panel to cool or heat the space W0. The radiation panel module 40A and the radiation panel module 40B are connected by piping or the like, and the air W that has passed through the radiation panel module 40A is supplied to the radiation panel module 40B. The air W supplied from the indoor unit 10 passes through the radiating panel module 40A and the radiating panel module 40B, and is blown out from the outlet W2A into the space W0 to cool or heat the space W0. As described above, the air conditioning system 100 performs air conditioning by the two systems of the radiation type and the convection type to perform cooling and heating of the space W0.

Next, an example of the configuration and arrangement of the radiation panel module 40 will be described.
FIG. 2 is a diagram showing a radiant panel module and an example of its arrangement according to an embodiment of the present invention. FIG. 2 shows a plan view of the radiation panel module 40. In the example shown in FIG. 2, four radiating panel modules 40A, 40B, 40C, and 40D are arranged on the floor of the space W0. The configuration of the radiation panel module 40 will be described using the radiation panel module 40A as an example. The radiation panel module 40A includes a damper 42A, flow path forming members 41A1, 41A2, 41A3, 41A4, 41A5, 41A6, a damper control unit 43A, an inlet unit 44A, and an outlet unit 45A. The upper surface (the floor of the space W0) of the radiation panel module 40A is formed by a radiation panel (not shown). The damper control unit 43A controls the opening and closing operation of the damper 42A based on an instruction from the control device 30. When the damper 42A is at the position indicated by the solid line (open state), the air W flowing from the inlet 44A passes through the bypass flow passage 46A in the direction indicated by the solid arrow, and is sent out from the outlet 45A. On the other hand, when the damper 42A is at the position shown by the dashed line (closed state) under the control of the damper control unit 43A, the air W flowing from the inlet 44A flows in the heat exchange channels 47A1, 47A2, 47A2 in the direction shown by the dashed arrow. It passes through 47A3, 47A4, 47A5, 47A6, 47A7, and is sent out from the outlet 45A.

  When the air W passes through the heat exchange channel 47A1, etc., the radiation heat from the radiant panel module 40A increases, and the floor (radiant panel) becomes warm during heating. Conversely, when the air W passes through the bypass flow passage 46A, the rise in temperature of the floor in the area where the radiant panel module 40A is arranged is suppressed, and the warm air W is used for convective air conditioning. For example, when the user spends in the area where the radiation panel module 40A is arranged, the remote controller or the like issues an instruction to switch the damper 42A of the radiation panel module 40A, and the air W passes through the heat exchange channel 47A1 or the like. Can be controlled. Alternatively, when the user spends in the area where the radiating panel module 40A is arranged during the cooling operation, the remote controller gives an instruction to switch the damper 42A to suppress the feet from cooling down, and the air W passes through the bypass passage 46A. Can be controlled. The radiation panel modules 40B to 40D have the same configuration.

  As shown, the radiation panel module 40A and the radiation panel module 40B are connected by a pipe 50A. Similarly, the radiation panel module 40C and the radiation panel module 40D are connected by a pipe 50C. The duct 13 branches into two and is connected to the entrances 44A and 44C. The air W whose temperature has been controlled is supplied from the indoor unit 10 to the entrance 44A of the radiation panel module 40A and the entrance 44C of the radiation panel module 40C via the duct 13. The air W supplied to the radiant panel module 40A passes through the bypass channel 46A or the heat exchange channel 47A1, etc., and is supplied from the outlet 45A to the inlet 44B of the radiant panel module 40B via the pipe 50A. Similarly, the air W supplied to the radiant panel module 40C passes through the inside of the radiant panel module 40C, and is supplied from the outlet 45C to the inlet 44D of the radiant panel module 40D via the pipe 50C. The same applies to the radiation panel modules 40B and 40D. The air W sent out from the outlets 45B and 45D by the radiating panel modules 40B and 40D is blown out from the outlets W2A to W2D into the space W0.

  Since the dampers 42A to 42D of the radiant panel modules 40A to 40D can be independently controlled, for example, only the radiant panel module 40A closes the damper 42A so that the air W flows through the heat exchange channel 47A1 and the like. The radiating panel modules 40B to 40D can control the dampers 42B to 42D to be in the open state, respectively.

  The air W blown out from the outlets W2A to W2D to the space W0 cools or heats the space W0, and is sucked into the indoor unit 10 again from the inlet W1. As illustrated in FIGS. 1 and 2, the intake port W1 on the ceiling and the outlet ports W2A to W2D can be provided at separate positions, and a plurality of radiating panel modules 40 can be arranged between them. For example, if the inlet W1 and the outlet W2A are provided at positions near both ends of the room to be air-conditioned, the entire room can be air-conditioned evenly in the convection type air-conditioning. Further, by connecting the plurality of radiant panel modules 40 in any direction via the pipe 50, the radiant panel can be arranged in a two-dimensional plane. Thereby, the whole room can be air-conditioned by the radiation type air-conditioning.

  The switching of the damper 42A is not limited to the control of switching between the completely open state and the closed state. For example, a stepping motor may be used so that the state can be switched between an open state and a closed state in multiple stages. Thereby, the flow rate of the air W flowing into the heat exchange flow path 47A1 and the like and the flow rate of the air W flowing into the bypass flow path 46A can be adjusted, and more precise temperature control can be performed. For example, when the user feels that the temperature of the floor is high during heating, the damper control unit 43A may control the position of the damper 42A to a middle position between the open state and the closed state according to a user's instruction. Then, since a smaller amount of air W flows into the heat exchange channel 47A1 and the like than in the case where the closed state is controlled, it is possible to suppress a rise in the temperature of the floor.

  Returning to FIG. 1, the air W sucked from the suction port W <b> 1 exchanges heat with the indoor heat exchanger 2 provided in the indoor unit 10, is controlled to an appropriate temperature, and is sent out to the duct 13 again by the fan 9. Is done. The indoor unit 10 includes an indoor heat exchanger 2, a fan 9, a temperature sensor 11, a humidity sensor 12, and a control device 30. The temperature sensor 11 measures the temperature of the air W sucked from the suction port W1. The humidity sensor 12 measures the humidity (relative humidity) of the air W sucked from the suction port W1. The control device 30 controls the rotation speed of the fan 9 based on the measurement values of the temperature sensor 11 and the humidity sensor 12 and sends out the air W to the duct 13. The indoor unit 10 is connected to the outdoor unit 20 by the refrigerant pipe 6, a communication line (not shown), and the like. The indoor unit 10 and the outdoor unit 20 constitute a refrigeration cycle, heat and cool the refrigerant by circulating the refrigerant in the refrigeration cycle, and control the air W to a desired temperature through the indoor heat exchanger 2. .

Here, the operation of the refrigeration cycle by the indoor unit 10 and the outdoor unit 20 will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of a refrigerant circuit according to an embodiment of the present invention.
As shown in FIG. 3, the indoor unit 10 includes the indoor heat exchanger 2 and the fan 9. The outdoor unit 20 includes a compressor 1, an expansion valve 3, an outdoor heat exchanger 4, and a four-way valve 5. The compressor 1, the indoor heat exchanger 2, the expansion valve 3, the outdoor heat exchanger 4, and the four-way valve 5 are connected by a refrigerant pipe 6.
The compressor 1 compresses the refrigerant, and discharges the compressed high-temperature, high-pressure refrigerant. In the heating operation, the refrigerant circulates in the direction of arrow 8. That is, the refrigerant discharged from the compressor 1 is supplied to the indoor heat exchanger 2 via the four-way valve 5. In the indoor heat exchanger 2, the refrigerant radiates heat to the air W sucked from the suction port W1, condenses and liquefies. The condensed refrigerant is decompressed by the expansion valve 3 and becomes a low-pressure refrigerant. The low-pressure refrigerant is supplied to the outdoor heat exchanger 4 and is vaporized by absorbing heat from outside air. The vaporized refrigerant passes through the four-way valve 5 and is sucked into the compressor 1. The compressor 1 compresses a low-pressure refrigerant and discharges a high-pressure refrigerant.

  In the cooling operation, the refrigerant circulates in the direction of arrow 7. That is, the high-pressure refrigerant discharged from the compressor 1 is supplied to the outdoor heat exchanger 4 via the four-way valve 5 and radiates heat to the outside air to condense. The condensed refrigerant is decompressed by the expansion valve 3. The low-pressure refrigerant is supplied to the indoor heat exchanger 2 and absorbs heat from the air W to cool the air W and evaporate. The vaporized refrigerant passes through the four-way valve 5 and is sucked into the compressor 1. The compressor 1 compresses a low-pressure refrigerant and discharges a high-pressure refrigerant.

  The control device 21 of the outdoor unit 20 switches the four-way valve 5 according to heating and cooling, and drives the compressor 1 at a rotation speed according to the difference between the temperature of the air W measured by the temperature sensor 11 and the set temperature. Thus, the refrigeration cycle is operated such that the temperature of the space W0 becomes the set temperature set by the user. The air W and the refrigerant exchange heat in the indoor heat exchanger 2. The control device 30 controls the fan 9 at a predetermined rotation speed, and sends out the air W after the heat exchange controlled to a desired temperature to the duct 13. Next, the control device 30 will be described.

FIG. 4 is a block diagram illustrating an example of a control device according to an embodiment of the present invention.
The control device 30 is a computer device such as a microcomputer, for example. As illustrated, the control device 30 includes a sensor information obtaining unit 31, a setting information obtaining unit 32, a timer 33, a storage unit 34, a control unit 35, and a communication unit 36. The control device 30 performs various controls on the indoor unit 10. In this specification, the control device 30 has a function of preventing dew condensation from occurring on the air path behind the radiant panel module 40, the pipe 50A, and the like after the cooling operation ends. The explanation is centered.

The sensor information acquisition unit 31 acquires a measured value of the temperature of the air W from the temperature sensor 11 and a measured value of the humidity of the air W from the humidity sensor 12.
The setting information acquisition unit 32 acquires various setting information input by a user from a remote controller or the like. For example, the setting information acquisition unit 32 instructs start and stop of operation, setting of cooling / heating, setting of room temperature, setting of air volume, and which area of the floor (any of the radiation panel modules 40A to 40D) is heated ( Or whether to cool).
The timer 33 measures time.
The storage unit 34 stores various information such as measured values of temperature and humidity acquired by the sensor information acquisition unit 31 and various setting information acquired by the setting information acquisition unit 32. Further, the storage unit 34 stores various programs that realize the functions of the control device 30.

  The control unit 35 controls the indoor unit 10 and controls the air conditioning system 100 in cooperation with the outdoor unit 20. For example, when the setting information acquisition unit 32 acquires a cooling operation start instruction and a set temperature at the time of cooling, the control unit 35 transmits the measurement of the temperature sensor 11 to the control device 21 of the outdoor unit 20 via the communication unit 36. Notify the setting information together with the value. The control device 21 drives the compressor 1 based on the difference between the measurement value of the temperature sensor 11 and the set temperature, and operates the refrigeration cycle so that the air W reaches a desired temperature. Further, for example, when the setting information acquisition unit 32 acquires the setting information of the predetermined air volume, the control unit 35 controls the rotation speed of the fan 9 so that the air volume of the air W supplied to the duct 13 becomes the predetermined air volume. I do. For example, when the air volume can be set in three stages of high, medium, and low, the rotation speed of the fan 9 is determined for each of those settings, and the control unit 35 determines the rotation speed corresponding to the air volume setting set by the user. Drives the fan 9. Further, for example, when the user sets so that the area of the radiation panel module 40A is not cooled too much during cooling, the control unit 35 instructs the damper control unit 43A to open the damper 42A.

  The control unit 35 continues the operation of the fan 9 even after the cooling operation is completed, and prevents dew condensation on the air path behind the radiant panel module 40. For example, while the air-conditioning system 100 is performing the cooling operation, the air passage of the radiation panel module 40 is often cooled and has a lower temperature than the space W0. When the fan 9 stops at the same time as the end of the cooling operation, the flow of the air W from the outlets W2A to W2D to the space W0 stops, and conversely, the air W can flow from the space W0 to the air path side of the radiation panel module 40. There is. Then, there is a possibility that the relatively high-temperature air W is cooled in the air path of the radiation panel module 40 and dew is formed in the air path. Therefore, in the present embodiment, the fan 9 is operated for a while to prevent dew condensation after the cooling operation is completed, and the backflow of air from the space W0 to the radiating panel module 40 is prevented, thereby preventing dew condensation in the air passage. I do.

  Specifically, when the user performs an operation to end the cooling operation, the instruction information is transmitted to the outdoor unit 20, and the control device 21 stops the operation of the compressor 1. On the other hand, in the indoor unit 10, the control unit 35 continues the operation of the fan 9 even after the cooling operation ends. Since the operation of the fan 9 is continued, the flow of the air W from the outlet W2A or the like to the space W0 can prevent the air from flowing from the space W0 into the air path of the radiation panel module 40. Further, the cooled air existing in the duct 13, the radiation panel module 40, and the like is discharged into the space W0, and the air W existing in the space W0 at the end of the cooling operation is sucked from the suction port W1 and is cooled by the fan. The air W is sent out to the duct 13 through the radiator 9, and after passing through the radiation panel module 40, is circulated from the outlet W2A and the like into the space W0. As a result, the temperature difference between the space W0 and the inside of the radiation panel module 40 disappears, and even if the air W flows from the space W0 to the inside of the radiation panel module 40, no dew condensation occurs.

  Note that the control unit 35 may control the damper control unit 43A so as to maintain the same open / close state as at the time of the end of the cooling operation for the damper 42A such as the radiant panel module 40A, and may continue the operation of the fan 9. Alternatively, control may be performed such that the open / close state of the damper 42A such as the radiation panel module 40A is switched at predetermined time intervals.

  The communication unit 36 performs communication with the control device 21. For example, when the setting information acquisition unit 32 acquires the operation stop instruction, the communication unit 36 transmits the operation stop instruction to the control device 21 of the outdoor unit 20. Further, the communication unit 36 communicates with the damper control unit 43A and the like. For example, when the control unit 35 instructs to close the damper 42A, the communication unit 36 transmits the instruction information to the damper control unit 43A.

Next, the flow of the process of the dew condensation prevention operation after the end of cooling according to the present embodiment will be described by taking the configuration of the air conditioning system 100 of FIGS. 1 to 4 as an example.
FIG. 5 is a flowchart of the dew condensation prevention operation according to the embodiment of the present invention.
It is assumed that the air conditioning system 100 is in a cooling operation. During execution of the cooling operation, the communication unit 36 transmits the temperature of the air W obtained by the temperature sensor 11 obtained by the sensor information obtaining unit 31 to the control device 21 of the outdoor unit 20 at predetermined time intervals. The control device 21 operates the refrigeration cycle by adjusting the rotation speed of the compressor 1 so that the temperature of the air W approaches the set temperature. Further, the control unit 35 controls the number of revolutions of the fan 9 so that the air volume is set by the user.

  First, the air-conditioning system 100 ends the cooling operation according to a user's instruction (step S11). Specifically, when the user inputs an instruction to stop the cooling operation using a remote controller or the like, the communication unit 36 transmits the instruction to stop to the control device 21 of the outdoor unit 20. The control device 21 stops the operation of the refrigeration cycle by stopping the compressor 1 or the like. In the indoor unit 10, based on the acquisition of the cooling operation stop instruction information, the control unit 35 continues the operation of the fan 9 while starting to monitor the elapsed time after the cooling operation is stopped using the timer 33. (Step S12). The control unit 35 may maintain the rotation speed of the fan 9 as it is during the cooling operation, or may change the rotation speed to a predetermined rotation speed set for the dew condensation prevention operation. Further, the sensor information acquisition unit 31 acquires the relative humidity at the time of the end of the cooling measured by the humidity sensor 12 (Step S13). The control unit 35 sets the operation time of the fan 9 after the cooling operation ends based on the relative humidity acquired by the sensor information acquisition unit 31 (Step S14). For example, the control unit 35 holds a setting table that defines the relationship between the relative humidity and the operation time, and the control unit 35 sets a continuation time according to the relative humidity at the end of cooling based on the setting table. I do. In this setting table, a longer operation time is set for a higher relative humidity. That is, as the humidity of the space W0 at the end of the cooling operation is higher, the control unit 35 operates the fan 9 for a longer time after the end of the cooling operation.

  Further, the control unit 35 may continue the operation of the fan 9 for a predetermined time without depending on the relative humidity. The predetermined time is, for example, the cooled state remaining in the space from the outlet of the indoor unit 10 to the outlet W2A at the end of the cooling operation, such as the duct 13, the radiation panel modules 40A to 40D, the pipe 50A, and the like. May be the time required until the air W is blown out from the outlet W2A or the like into the space W0.

  Next, the control unit 35 refers to the time measured by the timer 33 and determines whether or not the operation time set in step S14 has elapsed since the cooling operation ended (step S15). The control unit 35 continues the operation of the fan 9 until the set operation time elapses. When the set operation time has elapsed (Step S15; Yes), the control unit 35 stops the fan 9 (Step S16).

  Alternatively, instead of setting the operation time, for example, a temperature sensor is provided in an air path such as the radiation panel module 40A, and the control unit 35 controls the temperature sensor provided in the air path and the indoor unit 10 measured by the temperature sensor 11. The difference between the temperature of the air W at the suction port W1 and the temperature of the air W is within a predetermined range (a temperature difference at which condensation does not occur even if air flows from the space W0 to the air path side after the fan 9 stops). The operation of the fan 9 may be continued until the state is maintained for a certain time or longer.

During the operation of the fan 9, the control unit 35 may instruct the damper control unit 43A or the like to switch the open / close state of the damper 42A, and control the air W to flow through all the flow paths once.
Further, the rotation speed for the dew condensation prevention operation may be arbitrarily set by the user, and the length of the operation time after the cooling operation may be set according to the level of the rotation speed. For example, when the user sets the air volume small, a longer operation time may be set (step S14) than when the air volume is set large.

  According to the present embodiment, the air conditioner (the indoor unit 10 and the outdoor unit 20) that inhales the air W in the space W0 to be air-conditioned and controls the temperature of the air W is disposed on a surface in contact with the space W0. A radiation panel module 40, a fan 9 that sends out the air W whose temperature is controlled by the air conditioner to the radiation panel module 40, and an outlet W2A that blows the air W that has passed through the radiation panel module 40 into the space W0. In the air conditioning system 100, after the cooling operation is completed, the air W in the space W0 flows into the cooled air radiating panel module 40 on the air path side to prevent dew condensation on the air path (the rear surface of the radiating panel) and generation of mold. Can be.

In addition, it is possible to appropriately replace the components in the above-described embodiment with known components without departing from the spirit of the present invention. The technical scope of the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the fan 9 is controlled to be continuously operated after the cooling operation is completed. However, the same control may be performed after the dehumidifying operation in the air conditioning system 100. Further, in the above embodiment, the example in which the radiation panel module 40 and the like are arranged on the floor surface has been described, but they may be arranged on the ceiling or the wall surface.
