The following describes an embodiment of the present invention with reference to the drawings. However, the embodiment described below has various limitations that are technically preferable for implementing the present invention, but the technical scope of the present invention is not limited to the following embodiment and illustrated example. Note that the directions in the following embodiment and illustrated example are set solely for the convenience of explanation.

[Building Overview]
1 to 3, the reference numeral 1 denotes a building. The building 1 is a detached house having a first floor and a loft floor above the first floor. The roof 1a of the building 1 has a ridge, a roof surface that is short from the ridge to the eaves and formed with a steep slope, and a roof surface that is long from the ridge to the eaves and formed with a gentle slope.
A solar cell array is installed on the wide, gently sloping roof surface, allowing the use of a photovoltaic power generation system. Furthermore, a glass heat collecting module on the solar cell array collects solar heat and exchanges it appropriately, enabling air conditioning (temperature and humidity control) of the target room 15, which will be described later.

Outside the building 1 (but within the grounds), there is a carport 2 in the southwest position, a front porch 3 in the northwest position, and a terrace 4 in the northeast position.
The carport 2 and the entrance porch 3 are adjacent to each other on the north and south sides, and along their western sides, multiple (three) prefabricated columns 5, each formed into a rectangular cylindrical cross section, are erected at intervals from each other. These prefabricated columns 5 are positioned away from the first floor of the building 1, and support the part of the loft floor that protrudes beyond the first floor and the roof 1a of the building 1.
The assembled column 5 is composed of four column members arranged at the four corners and structural panels provided between adjacent column members on the left, right, front and rear.

An entrance 6 (entrance floor) is provided on the north side of the carport 2 and on the east side of the entrance porch 3. The entrance door of the entrance 6 is located between two prefabricated pillars 5 erected on the entrance porch 3. A storage shelf 6a is installed in the entrance 6.
In addition, an entrance hall 7, which is one step higher than the entrance 6, is provided on the east side of the entrance 6, and a storage closet 8 is provided on the north side of the entrance 6.

To the north of the entrance hall 7 is a machine room 9 in which the indoor unit of the heat exchange unit is installed. The machine room 9 is separated from the entrance hall 7 by a door, and there is an underfloor airtight inspection hatch 9a in the floor for performing underfloor maintenance.

A pipe space 10 is provided on the east side of the machine room 9, and an equipment storage space 11 with a desiccant unit 11a installed below and an air conditioner indoor unit 11b (hereinafter, air conditioner 11b) installed above, and a pipe space 12 located on the outer wall side are provided on the east side of the pipe space 10. The equipment storage space 11 and the pipe space 12 are separated by a wall.
The desiccant unit 11a absorbs moisture (for dehumidification) by utilizing the moisture capacity of a moisture absorbent, and performs dehumidification in a room 15 (described later).
The air conditioner 11b is responsible for air conditioning the room 15. Note that louvers are provided on the front sides of the desiccant unit 11a and the air conditioner 11b.
Although not shown, a humidifier is also provided in a room 15 (for example, the equipment storage space 11) described below.

On the outdoor side of the exterior wall located to the north of the storage closet 8, the machine room 9, the pipe space 10, and the pipe space 12, there is an equipment installation space 13 equipped with a concrete floor slab. In this equipment installation space 13, an air conditioner outdoor unit 13a, a heat exchange unit outdoor unit 13b, an auxiliary heater 13c, and a hot water storage unit 13d are installed.

As described above, the various devices necessary to adjust the environment inside building 1 are grouped together on the north side of entrance 6 and entrance hall 7. This makes it easier to perform maintenance work, as it does not have to be performed in various places in building 1.

On the south side of the entrance hall 7, there is a staircase 14 with a staircase 14a that connects the first floor and the loft floor. Below the staircase 14a is an under-staircase storage space 14b, which is separated from the entrance hall 7 by a sliding door. There is also an under-floor airtight inspection hatch 14a in the floor of the under-staircase storage space 14b.

To the east of the entrance hall 7 is a room 15 (target room) that is used as a living room, dining room, kitchen, etc., and is the target of air conditioning and condensation suppression. Room 15 is separated from the entrance hall 7 by a door. Room 15 may be equipped with a sink with a stove, a dining table, etc., as needed.

The above-mentioned staircase 14 is provided on the west side of the entrance hall 7, and the space at the top of the stairs 14a is separated from a room 15 by a door.
Further, on the south side of the room 15 and the staircase 14, a storeroom 16 is provided which can be accessed from the space at the top of the stairs 14a in the staircase 14. The floor of the storeroom 16 also has an underfloor airtight inspection hatch 16a.

At the top of the stairs 14a is the loft floor, which is equipped with a loft room 17. The western end of the loft floor extends to the assembly column 5 and overhangs the first floor, making it longer in the east-west direction than in the north-south direction. The southern end of the loft floor is located above the exterior wall that constitutes the south-facing surface located in the northern part of the carport 2.

[About the applicable rooms]
Next, the room 15 which is the target room for air conditioning and condensation suppression will be described in more detail.
The room 15 is a space surrounded by a floor 20, a number of walls 21 to 26, and a number of ceilings 27 to 29. The surface of the floor 20 is formed from a flooring material, and is provided without any steps or slopes.

The multiple walls 21 to 26 include an east wall 21, which is an exterior wall on the east side; a north wall 22, which is an exterior wall on the north side facing the terrace 4; a south wall 23, which is an exterior wall on the south side; a west wall 24 provided between the entrance hall 7 and the staircase 14; a storeroom side wall 25 provided between the storeroom 16; and a side wall 26 provided between the pipe space 10 and the equipment storage space 11.

The east wall 21 is a wall that does not have an opening that can be opened to the outdoors.
In addition, the west wall 24 does not have any openings that can be opened to the outdoors, but has openings (entrances) that can be opened to the entrance hall 7 and the staircase 14, and each of these openings is provided with the above-mentioned doors.

1 and 3, an opening 22a is formed over most of the north wall 22. The width of the opening 22a is slightly shorter than that of the north wall 22. The height of the opening 22a is shorter than that of the north wall 22 because the north wall 22 extends above the eaves ceiling.
A window sash that opens and closes an opening 22a is provided on the north wall 22. The window sash is a bay window sash that is set to a height slightly lower than the height from the floor 20 of the room 15 to a second ceiling 28 (described later). By opening the window sash, it is possible to move between the room 15 and the terrace 4.

As shown in Figures 1 and 3, the south wall 23 has a lower opening 23a that acts as a ground-level window at a height near the floor 20, and an upper opening 23b that acts as a high window at a height near the third ceiling 29 (described later). The width of the openings 23a and 23b is slightly shorter than that of the south wall 23. The lower edge of the lower opening 23a is slightly higher than the floor 20, and the upper edge of the upper opening 23b is slightly lower than the third ceiling 29. The heights of the openings 23a and 23b are set to be equal, and between the openings 23a and 23b there is a wall section 23c with no opening.

The multiple ceilings 27 to 29 include a first ceiling 27 located at the highest position near the center of the room 15, a second ceiling 28 located at a lower position than the first ceiling 27 on the north side of the room 15, and a third ceiling 29 located at a lower position than the first ceiling 27 on the south side of the room 15.
A ceiling with a portion of it (first ceiling 27) recessed upward like this is called a raised ceiling.

The second ceiling 28 and the third ceiling 29 are located at the same height. Furthermore, the ceiling panels constituting the second ceiling 28 and the third ceiling 29 extend toward the first ceiling 27 in the center.
The extension plate portion 28a of the second ceiling extending toward the first ceiling 27 bridges between the east side wall 21 and the west side wall 24. Furthermore, the extension plate portion 29a of the third ceiling 29 extending toward the first ceiling 27 bridges between the east side wall 21 and the storeroom side wall 25. Moreover, each of the extension plate portions 28a, 29a is disposed with a gap between it and the first ceiling 27.
Illumination devices 28b, 29b are provided on the upper surface of each of the extension plate portions 28a, 29a, and when the illumination devices 28b, 29b are turned on, the light strikes the first ceiling 27 and is reflected downward into the room 15. Therefore, the illumination devices 28b, 29b provided on the upper surface of each of the extension plate portions 28a, 29a function as indirect lighting.

As shown in Fig. 3, an opening 27a is formed above the extension plate portion 28a of the second ceiling 28 of the first ceiling 27. Meanwhile, an opening 18a is also formed in the south wall 18 of the loft room 17. The opening 27a of the first ceiling 27 and the opening 18a of the wall 18 of the loft room 17 are connected by a duct D passing through the attic. That is, the room 15 and the loft room 17 are connected through the duct D. This allows the air in the room 15 to be sent to the loft room 17. In other words, an air exhaust path is provided in the room 15 at a position blocked by the extension plate portion 28a.
A fan 27b is provided in the first ceiling 27 near the opening 27a to draw in air from within the room 15 and more efficiently send the air to the loft room 17. The opening 18a in the wall 18 of the loft room 17 can be opened or closed by an opening/closing lid 18b.
A fan 19a is provided on the wall (exterior wall) located on the east side of the loft room 17 to exhaust air from within the loft room 17. A fan 19b is also provided above the ceiling of the loft room 17 (i.e., the attic) so that air from within the attic can be exhausted. Operating these fans 19a and 19b is preferable in the summer because it prevents the area around the ceiling of the loft room 17 from heating up. An air conditioner 19c is also installed in the loft room 17.
On the other hand, in winter, if the fans 19a and 19b are not operated and the warm air from the room 15 is taken into the loft room 17, the loft room 17 can be heated even if the air conditioner 19c is not operated.

In the room 15 in which the air exhaust path is provided as described above, a radiant heating and cooling device 30 is built into at least the east wall 21 among the floor 20, the multiple walls 21-26, and the multiple ceilings 27-29 surrounding the room 15. In this embodiment, as shown in Figures 2 and 3, the radiant heating and cooling device 30 is built into the east wall 21 and the west wall 24. However, this is not limited to this, and the radiant heating and cooling device 30 may be built into the floor 20, the other walls 22, 23, 25, 26, and each of the ceilings 27-29.

The radiant heating and cooling device 30 includes a plurality of cooling and heating panels 31 with tubes (not shown) through which cold water or hot water flows inside, and a plurality of circulation pipes 32 for circulating the cold water or hot water between the panels and a water source. The circulation pipes 32 pass under the floor and connect the plurality of cooling and heating panels 31 to the water source.
The water source is a heat exchange unit installed in the machine room 9, and the heat exchange unit is capable of circulating cold water in the summer and hot water in the winter to the radiant heating and cooling device 30.

In addition, in such a room 15, dehumidification and humidification (humidity control) are performed by the above-mentioned desiccant unit 11a and humidifier, and air conditioning (adjustment of temperature, humidity, cleanliness, airflow, etc.) is performed by the above-mentioned air conditioner 11b. Note that humidity control may also be performed by the air conditioner 11b without using the desiccant unit 11a and humidifier.

The radiant heating and cooling device 30 is an air conditioning facility for conditioning the room 15 which is a target room, and as shown in Fig. 5, the radiant heating and cooling device 30 which is an air conditioning facility is connected to a control unit 35 and can be switched on and off by the control unit 35. In other words, the control unit 35 is a controller for controlling the air conditioning facility.
In addition, the control unit 35 in this embodiment is an HA terminal control unit, and the radiant heating and cooling device 30 is equipped with an HA connector and is connected by a JEM-A (HA) terminal cable.
Although not shown, the control unit 35 is assumed to be provided at an arbitrary location in the room 15 (for example, near a temperature and humidity sensor 33 described later).
Furthermore, in this embodiment, the air conditioning equipment is the radiant heating and cooling device 30, but is not limited thereto, and may include the above-mentioned desiccant unit 11a, air conditioner 11b, and humidifier. In addition, other types of air conditioning equipment may be included, and the number of air conditioning equipment is not particularly limited.

The room 15 is also provided with a temperature and humidity sensor 33 that measures the temperature and humidity (relative humidity) within the room 15. To explain in more detail, the temperature and humidity sensor 33 is provided on at least the east wall 21 of the room 15. Furthermore, the temperature and humidity sensor 33 is provided in a position near the opening 22a in the north wall 22 of the east wall 21, and in a position near the second ceiling 28. The temperature and humidity sensor 33 located in this position is easily affected by outside air when the opening 22a in the north wall 22 is opened.
However, the location of the temperature and humidity sensor 33 is not limited to this, and it may be provided in a position near the opening 23 b in the south wall 23 of the east wall 21 and in the vicinity of the third ceiling 29 .
In this embodiment, the east wall 21 is the first wall on which the temperature and humidity sensor 33 is arranged, and either the north wall 22 or the south wall 23 is the second wall in which openings (opening 22a, opening 23b) are formed.
Since the radiant heating and cooling device 30 is provided inside the east wall 21 and the opening 22a is located nearby, condensation is likely to occur on the surface of the east wall 21. For this reason, it is desirable to provide the temperature and humidity sensor 33 on the east wall 21.

In short, the temperature and humidity sensor 33 is provided at a position that is easily affected by the outdoor environment when the window (for example, the openings 22a and 23b) is open.
When the windows are opened during hot seasons such as summer, the warm air, which has a tendency to rise, flows into the vicinity of the ceilings 27, 28, and 29 in the room 15 and tends to remain there even after the windows are closed. Furthermore, warm air from the outdoors flows in from the top of the open windows, and conversely, cooled air from inside the room flows out from the bottom of the open windows. In other words, air is exchanged. Therefore, not only does the temperature in the vicinity of the ceilings 27, 28, and 29 rise, but the humidity also tends to rise in the east wall 21, which was cooled by the radiant heating and cooling device 30, closer to the opening 22a and the second ceiling 28.
The graph shown in FIG. 4 shows the degree of increase and decrease in absolute humidity when the opening 22a of the north wall 22 is suddenly opened from 11:41 to 11:43. This graph shows the absolute humidity at a total of 11 positions, including the upper (near the second ceiling 28), middle, and lower (near the floor 20) near the opening 22a, the upper, middle, and lower positions at a position 2000 mm away from the opening 22a, the upper, middle, and lower positions at a position 3000 mm away from the opening 22a, and the upper, middle, and lower positions at a position 5000 mm away from the opening 22a (near the openings 23a and 23b formed in the south wall 23). This graph shows that, of the absolute humidity at a total of 11 positions, the absolute humidity is highest at the position closest to the opening 22a and the second ceiling 28.

The temperature and humidity sensor 33 is an element that constitutes the control logic in the control of the air conditioning equipment by the control unit 35, which is a controller. That is, the control unit 35 controls the air conditioning equipment (radiant heating and cooling device 30) according to a preset control logic based on the measurement results of the temperature and humidity sensor 33. In other words, the air conditioning equipment (radiant heating and cooling device 30) conditions the air in the room 15 according to the measurement results of the temperature and humidity sensor 33.

In this embodiment, the temperature and humidity sensor 33 is configured such that the temperature and humidity sensor module (element) is housed within the housing, but this is not limited thereto and the sensor may be provided outside the housing.

[About the air conditioning system]
Next, the air conditioning system will be described.
In room 15 (and therefore building 1), which is the target room for air conditioning and condensation suppression, an air conditioning system is constructed that includes a temperature and humidity sensor 33, air conditioning equipment (radiant heating and cooling device 30), and a control unit 35 that serves as a controller, as shown in Figure 5.

A first communication network N1, such as a LAN (Local Area Network), is established within the building 1, and a temperature and humidity sensor 33, a control unit 35, and a portable information terminal 36 carried by the resident are communicatively connected.
Data on the temperature and humidity of the room 15 measured by the temperature and humidity sensor 33 is transmitted to the control unit 35 via the local area network, and the control unit 35 controls the air conditioning equipment based on the temperature and humidity data.
The first communication network N1 may be, for example, Wi-Fi (registered trademark), and the temperature and humidity sensor 33 may periodically transmit measurement results to the control unit 35 using a Wi-Fi client function.

The mobile information terminal 36 is a computer having a display device, an input device, a storage device, a microprocessor, etc., and may be a portable communication terminal such as a smartphone, a tablet terminal, a feature phone, a PDA (Personal Digital Assistant), a laptop personal computer, etc. The mobile information terminal 36 is capable of transmitting and receiving data to and from the control unit 35 via the first communication network N1, and can check the current values of temperature and humidity, and set the control logic for the air conditioning equipment by the control unit 35.

The control unit 35 also includes a recording medium (not shown) such as an SD card, and data logging is performed using the recording medium. The control unit 35 is also communicatively connected to an external data server 37 via a second communication network N2 such as a Wide Area Network (WAN).
The external data server 37 is a data server provided outside (outside the premises of) the building 1, and receives logging data from the control unit 35. The received data is the same as the data recorded on the recording medium in the control unit 35, and specifically, the results of temperature and humidity measurement by the temperature and humidity sensor 33 and data on the operating status of the air conditioning equipment are recorded and accumulated. Furthermore, the data accumulated in the external data server 37 will be utilized in the future creation and development of control logic (control program) for the air conditioning equipment by the control unit 35.

The humidity measured by the temperature and humidity sensor 33 is a relative humidity that indicates the current amount of water vapor relative to the maximum amount of water vapor that can be contained in the air.
The control unit 35 includes an absolute humidity calculation means (not shown) that calculates the weight absolute humidity based on the temperature and relative humidity measured by the temperature and humidity sensor 33, based on a conventionally known weight absolute humidity calculation formula. Weight absolute humidity indicates the proportion of water vapor to the weight of 1 kg of "dry air" obtained by removing water vapor from air. In other words, the control unit 35 can measure the temperature, relative humidity, and absolute humidity (weight absolute humidity) in the room 15.
Instead of the control unit 35 being provided with the absolute humidity calculation means, a temperature and humidity sensor 33 capable of measuring temperature, relative humidity, and absolute humidity may be employed.

As shown in FIG. 6, for example, the control unit 35, which is the controller, is capable of setting upper and lower limits for the temperature and/or humidity measured by the temperature and humidity sensor 33 as control logic for controlling the air conditioning equipment (radiant heating and cooling device 30), and setting the operating state of the air conditioning equipment corresponding to when the temperature and/or humidity measured by the temperature and humidity sensor 33 reaches the upper and lower limits.

Furthermore, since the control unit 35 is an HA terminal control unit and the air conditioning equipment is equipped with an HA connector as described above, the setting of the operating state of the air conditioning equipment as the control logic is a setting that switches the operation of the air conditioning equipment on and off when the temperature and/or humidity measured by the temperature and humidity sensor 33 reach upper and lower limit values.
However, this is not limited thereto. For example, an adapter dedicated to ECHONET Lite (registered trademark) may be connected to an air conditioning system, and the air conditioning system may be used as an ECHONET Lite compatible device. If the air conditioning system can be used as an ECHONET Lite compatible device, it is possible to control the operating state in addition to switching it on and off. In other words, it is possible to adjust the set temperature of the air conditioner 11b or adjust the set temperature of the heat exchange unit of the radiant heating and cooling device 30. When a technology related to a communication protocol such as ECHONET Lite is adopted, a HEMS (Home Energy Management System) controller may be adopted instead of the HA terminal control unit as the control unit.

To explain in more detail the control logic that can be set for the control unit 35, first, the controlled environment can be selected. In other words, the user can select whether the target of air conditioning to be set is temperature, relative humidity, or absolute humidity. Next, the upper and lower limit values for each controlled environment can be selected and set. Then, once the upper and lower limit values have been set, it is possible to set the on/off switching of the air conditioning equipment.
When a user wants to set a temperature, the user selects a temperature and sets an upper limit and a lower limit. Then, the user selects whether the operation of the radiant heating and cooling device 30 is turned on or off when the upper limit is reached. The user also selects whether the operation of the radiant heating and cooling device 30 is turned on or off when the lower limit is reached.

In the temperature settings exemplified in FIG. 6 , when the temperature reaches the upper limit during hot seasons such as summer (referring to a state in which the temperature inside the room 15 has risen and is hot), the radiant heating and cooling device 30 with its operation mode set to cooling is turned on, and when the temperature reaches the lower limit (referring to a state in which the temperature inside the room 15 has dropped too low), the radiant heating and cooling device 30 with its operation mode set to cooling is turned off.
On the other hand, during cold seasons such as winter, when the temperature reaches the upper limit (indicating a state in which the temperature inside room 15 has risen too high), the operation of the radiant heating and cooling device 30 with its operation mode set to heating is turned off, and when the temperature reaches the lower limit (indicating a state in which the temperature inside room 15 has dropped and become cold), the operation of the radiant heating and cooling device 30 with its operation mode set to heating is turned on.
Regarding the operating mode of the air conditioning equipment (radiant heating and cooling device 30), the air conditioning equipment itself has an automatic operation function that automatically selects the operating mode according to the temperature inside the room 15 and the outdoor temperature, or the operating mode from the previous operation is automatically inherited.

In the relative humidity setting illustrated in FIG. 6, when the relative humidity in the room 15 is high and the relative humidity reaches an upper limit, the operation of the radiant heating and cooling device 30, whose operating mode is set to cooling, is turned off to suppress the occurrence of condensation.
On the other hand, during periods when the relative humidity in the room 15 is low, when the relative humidity reaches a lower limit, the radiant heating and cooling device 30, whose operation mode is set to cooling, is turned on to suppress the occurrence of condensation.

In the absolute humidity setting illustrated in FIG. 6, when the absolute humidity in the room 15 is high and the absolute humidity reaches an upper limit, the operation of the radiant heating and cooling device 30, whose operating mode is set to cooling, is turned off to suppress the occurrence of condensation.
On the other hand, during periods when the absolute humidity in the room 15 is low, when the absolute humidity reaches a lower limit, the radiant heating and cooling device 30, whose operating mode is set to cooling, is turned on and operation is resumed, thereby suppressing the occurrence of condensation.

The control logic can be set by the control unit 35, which is a controller, or the mobile information terminal 36. In the description of the setting of the control logic, the air conditioning equipment refers to the radiant heating and cooling device 30, but may also include the desiccant unit 11a, the air conditioner 11b, and a humidifier.
FIG. 7(a) is a front view showing the control unit 35, which comprises a housing 40, a first button 41 (left), a second button 42 (middle), and a third button 43 (right) provided at the lower part of the front surface of the housing 40, and a display unit 44 located above these buttons 41, 42, and 43 and provided on most of the front surface of the housing 40.
The display unit 44 displays on the screen the date and time (year, month, date and time), the current values of temperature and humidity (relative humidity, absolute humidity) measured by the temperature and humidity sensor 33 shown in the "status" column, the upper limit value shown in the "High" example, the lower limit value shown in the "Low" column, and the current control mode of the air conditioning equipment by the control unit 35 shown in the "HA" row.
The current value, upper limit value, and lower limit value are divided into a "Temp (Temperature)" row, a "Humi_Rel (Relative Humidity)" row, and a "Humi_Abs (Absolute Humidity)" row.
In addition, three small display sections 44a, 44b, and 44c, each shorter in length and width than the display section 44, are displayed on the screen along the lower edge of the display section 44. The small display sections 44a, 44b, and 44c correspond to pressing of the buttons 41, 42, and 43 provided directly below the small display sections 44a, 44b, and 44c.

The current control mode of the air conditioning equipment by the control unit 35 shown in the "HA" row is "AUTO" in the example of Fig. 7(a), which is a mode in which the air conditioning equipment is automatically operated based on the set control logic. The control mode is switched by pressing the first button 41. When the first button 41 is pressed while "AUTO" is displayed on the small display section 44a, the display on the small display section 44a switches to "MANU", and the control mode switches to the manual mode.
Then, as shown in FIG. 7(b), when the control mode is switched to the manual mode, the small display section 44b in the center displays “ON” and the small display section 44c on the right side displays “OFF”, and the air conditioning equipment can be switched on and off by pressing the second button 42 and the third button 43.

FIG. 8 shows a parameter setting screen which is transitioned to when the second button 42 is pressed down in a state where "menu1" is displayed in the small central display portion 44b on the screen display shown in FIG.
More specifically, the parameter setting screen shown in FIG. 8 allows input of numerical values (parameters) for upper and lower temperature limits, temperature hysteresis, upper and lower relative humidity limits, relative humidity hysteresis, upper and lower absolute humidity limits, and absolute humidity hysteresis.
The small display section 44a on the left side displays "SET1," and can be switched up to "SET9" by pressing the first button 41. The small display section 44b in the center displays "- (minus)," and the small display section 44c on the right side displays "+ (plus)," allowing the parameter to be increased or decreased.
"SET1" corresponds to setting the upper limit of temperature, "SET2" corresponds to setting the lower limit of temperature, "SET3" corresponds to setting the temperature hysteresis, "SET4" corresponds to setting the upper limit of relative humidity, "SET5" corresponds to setting the lower limit of relative humidity, "SET6" corresponds to setting the relative humidity hysteresis, "SET7" corresponds to setting the upper limit of absolute humidity, "SET8" corresponds to setting the lower limit of absolute humidity, and "SET9" corresponds to setting the absolute humidity hysteresis.
In the example of Figure 8, "SET1" is displayed on the small display section 44a, so that it is possible to set the upper limit temperature. The upper limit temperature can be lowered by pressing the second button 42, and the upper limit temperature can be raised by pressing the third button 43.
Hysteresis refers to a setting range (also called adjustment sensitivity, operating gap, or dead band) and is set to prevent chattering during operation of the air conditioning equipment and to prevent it from being affected by noise. In other words, if hysteresis is not set, on/off switching will occur frequently, but by setting hysteresis, it is possible to prevent the air conditioning equipment from being switched on/off more than necessary.

FIG. 9 shows a logic setting screen which is transitioned to when the third button 43 is pressed in a state in which "menu2" is displayed in the small central display portion 44b on the screen display shown in FIG.
More specifically, on the logic setting screen shown in Fig. 9, it is possible to set whether to turn on or off the operation of the air conditioning equipment when the temperature, relative humidity, or absolute humidity reaches the upper or lower limit value set on the parameter setting screen in Fig. 8. In other words, it is possible to set the control logic for switching the operation of the air conditioning equipment on and off.
In this embodiment, it is possible to set two control logics, "Logic 1" and "Logic 2." The number of control logics that can be set in "Logic 1" and "Logic 2" is 13 in total, numbered from 0 to 12, and "Logic 1" and "Logic 2" can be set in combination with "AND/OR."

In addition to the small display section 44a, the display section 44 is provided with columns 44d, 44e, and 44f in which the selected control logic and "AND/OR" are displayed. The control logic selected in "Logic1" is displayed in the upper column 44d, and "AND" or "OR" is displayed in the middle column 44e.
The control logic selected in "Logic 2" is displayed in the lower column 44f.
The small display section 44a on the left side displays "SET1," and can be switched up to "SET3" by pressing the first button 41. The small display section 44b in the center displays "- (minus)," and the small display section 44c on the right side displays "+ (plus)." By pressing the second button 42 and the third button 43, respectively, the control logics displayed in the upper column 44d and the lower column 44f can be switched in the order of the numbers assigned to the multiple control logics.

The control logic "0" that can be set in "Logic 1" and "Logic 2" is "Nun (short for Nothing)," and allows the selection of not controlling the air conditioning equipment. Furthermore, the control logic "1" to "12" correspond to the control logic in FIG. 6 (see FIG. 11). Note that if there is no air conditioning equipment to be controlled, the air conditioning equipment will not be controlled.
Control logic "1" is "Temp Hi ON", which indicates control to turn on the air conditioning equipment when the temperature reaches the upper limit.
Control logic "2" is "Temp Hi OFF", which indicates control to turn off the air conditioning equipment when the temperature reaches the upper limit.
Control logic "3" is "Temp Lo ON", which indicates control to turn on the air conditioning equipment when the temperature reaches the lower limit.
Control logic "4" is "Temp Lo OFF", which indicates control to turn off the air conditioning equipment when the temperature reaches the lower limit.
Control logic "5" is "Humi_Rel Hi ON", which indicates control to turn on the air conditioning equipment when the relative humidity reaches the upper limit value.
Control logic "6" is "Humi_Rel Hi OFF", which indicates control to turn off the air conditioning equipment when the relative humidity reaches the upper limit value.
Control logic "7" is "Humi_Rel Lo ON", which indicates control to turn on the air conditioning equipment when the relative humidity reaches the lower limit.
Control logic "8" is "Humi_Rel Lo OFF", which indicates control to turn off the air conditioning equipment when the relative humidity reaches the lower limit.
Control logic "9" is "Humi_Abs Hi ON", which indicates control to turn on the air conditioning equipment when the absolute humidity reaches the upper limit value.
Control logic "10" is "Humi_Abs Hi OFF", which indicates control to turn off the air conditioning equipment when the absolute humidity reaches the upper limit value.
Control logic "11" is "Humi_Abs Lo ON", which indicates control to turn on the air conditioning equipment when the absolute humidity reaches the lower limit.
Control logic "12" is "Humi_Abs Lo OFF", which indicates control to turn off the air conditioning equipment when the absolute humidity reaches the lower limit.

In this embodiment, it is possible to set two control logics, "Logic 1" and "Logic 2," from among the control logics from "0" to "12," as described above, but it may also be possible to set three or more control logics.

In this way, the user can set the control of the air conditioning equipment, thereby enabling the user to adjust the air conditioning to his or her liking.
For example, when the room 15 is cooled during a hot season such as summer, and the surface temperature of the radiant heating and cooling device 30 reaches 22°C (which is also the temperature in the vicinity of the east wall 21 in which the radiant heating and cooling device 30 is installed), and the absolute humidity at that time is 16 g/kg' or higher, condensation will inevitably occur on the surface of the east wall 21. For this reason, it is desirable to set the upper limit of the absolute humidity to 16.0 g/kg', as shown in Figures 7(a) and 8.

According to this embodiment, the air conditioning of the target room 15 by the radiant heating and cooling device 30, which is an air conditioning equipment, is affected by the measurement results of the temperature and humidity of the target room 15 by the temperature and humidity sensor 33. On the other hand, since the temperature and humidity sensor 33 is also arranged near the opening 22a (23b) formed in the second wall 22 (23) of the first wall 21, it is easily affected by the outside air when the opening 22a (23b) of the second wall 22 (23) is opened. If the difference between the temperature in the target room 15 and the outside air temperature is large, condensation is likely to occur on the walls 21 to 24 of the target room 15, but if the temperature and humidity sensor 33 is arranged in such a place that is easily affected by the outside air, the air conditioning equipment 30 also performs air conditioning of the target room 15 according to the measurement results of the temperature and humidity sensor 33, so that condensation is less likely to occur on the walls 21 to 24 of the target room 15. In other words, it is possible to perform air conditioning of the target room 15 while effectively suppressing the occurrence of condensation on the walls 21 to 24 of the target room 15.

In addition, since the temperature and humidity sensor 33 is disposed on the first wall 21 near the ceiling 28 of the target room 15, when the opening 22a (23b) formed in the second wall 22 (23) is opened and warm air flows into the target room 15, the temperature of the warm air can be easily measured by the temperature and humidity sensor 33, especially during hot weather such as summer. The air conditioning equipment 30 conditions the air in the target room 15 according to the measurement results of the temperature and humidity sensor 33, so that the air conditioning of the target room 15 can be performed while more effectively suppressing the occurrence of condensation on the walls 21 to 24 of the target room 15.

In addition, since the air conditioning equipment is a radiant heating and cooling device 30 installed at least inside the first wall 21, condensation is less likely to occur on the first wall 21, whose temperature is directly regulated by the radiant heating and cooling device 30.

Furthermore, according to this embodiment, the controller 35 controls the radiant heating and cooling device 30, which is an air conditioning equipment, according to a preset control logic based on the measurement results of the temperature and humidity sensor 33. As a control logic, it is possible to set upper and lower limits for the temperature and/or humidity measured by the temperature and humidity sensor 33, and to set the operating state of the air conditioning equipment 30 corresponding to when the temperature and/or humidity measured by the temperature and humidity sensor 33 reaches the upper and lower limits. Therefore, when the inside of the target room 15 is about to become an environment in which condensation is likely to occur, the operating state of the air conditioning equipment 30 can be controlled according to the control logic. This makes it possible to air-condition the target room 15 while effectively suppressing the occurrence of condensation on the walls 21 to 24 of the target room 15.

In addition, when the temperature and/or humidity measured by the temperature and humidity sensor 33 reaches an upper or lower limit, the operation of the air conditioning equipment 30 can be switched on and off. Therefore, the operation of the air conditioning equipment 30 can be turned on according to the measurement results of the temperature and humidity sensor 33 to air-condition the target room 15 while suppressing the occurrence of condensation, and when it is not necessary, the operation of the air conditioning equipment 30 can be turned off to reduce running costs.

In addition, the controller 35 can select whether to control the air conditioning equipment 30 according to any one of the multiple control logics, or to control the air conditioning equipment 30 by combining at least two or more of the multiple control logics, so that it is possible to select a suitable control logic from a wide variety of options and control the air conditioning equipment 30.

In addition, the controller 35 controls the operation of the air conditioning equipment 30 to be switched on and off according to a first control logic among at least two or more control logics, and then controls the operation of the air conditioning equipment 30 to be switched on and off according to a control logic different from the first control logic, so that the operation of the air conditioning equipment 30 can be controlled by prioritizing multiple control logics.

The controller 35 also calculates the absolute humidity of the target room 15 from the temperature and humidity measured by the temperature and humidity sensor 33, turns off the operation of the air conditioning equipment 30 when the calculated absolute humidity exceeds the upper limit, and turns on the operation of the air conditioning equipment 30 when the calculated absolute humidity falls below the lower limit. This makes it possible to air-condition the target room 15 while effectively preventing condensation from forming on the walls 21 to 24 of the target room 15, especially during periods of high temperature such as summer.

[Modifications]
The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit of the present invention. Modifications are described below. The following modifications may be combined as far as possible. In each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and descriptions thereof are omitted or simplified.

[Modification 1]
Since cold air has the tendency to descend during cold seasons such as winter, it is desirable for the temperature and humidity sensor 33 to be located near the opening 22a in the east wall 21, which is the first wall, and near the floor 20.
To accommodate both hot and cold seasons, one temperature and humidity sensor 33 may be placed at a mid-height position on the east wall 21, or two temperature and humidity sensors 33 may be placed both near the ceiling 28 and near the floor 20. When the south wall 23 is used as the second wall, the wall section 23c without an opening is between the opening 23a, which is a ground-level window, and the opening 23b, which is a cleavage window, so it is preferable to place the two temperature and humidity sensors 33 near both the third ceiling 29 and near the floor 20, rather than placing the temperature and humidity sensor 33 at a mid-height position.

[Modification 2]
In the above embodiment, the radiant heating and cooling device 30 is used as an example of air conditioning equipment that is connected to the control unit 35 and can be switched on and off by the control unit 35. However, this is not limited to this, and any one or more of the radiant heating and cooling device 30, the air conditioner 11b, the dehumidifier (desiccant unit 11a), and the humidifier may be used.
In this modification, the air conditioning equipment includes a radiant heating and cooling device 30, an air conditioner 11b, a dehumidifier (desiccant unit 11a), and a humidifier. That is, the desiccant unit 11a, the air conditioner 11b, the humidifier, and the radiant heating and cooling device 30 each include an HA connector and are connected to the control unit 35 by a JEM-A (HA) terminal cable.

In room 15 (and therefore building 1), which is the target room for air conditioning and condensation suppression, an air conditioning system is constructed that includes a temperature and humidity sensor 33, air conditioning equipment (desiccant unit 11a, air conditioner 11b, humidifier, radiant heating and cooling device 30), and a control unit 35, which serves as a controller, as shown in Figure 10.
The mobile information terminal 36 is capable of sending and receiving data with the control unit 35 via the first communication network N1, and can check the current values of temperature and humidity, and set the control logic for the air conditioning equipment (desiccant unit 11a, air conditioner 11b, humidifier, radiant heating and cooling device 30) using the control unit 35.
The external data server 37 receives the logging data from the control unit 35 via the second communication network N2.

As shown in FIG. 11, the control unit 35, which is the controller, is capable of setting upper and lower limits for the temperature and/or humidity measured by the temperature and humidity sensor 33, and setting the operating state of the air conditioning equipment when the temperature and/or humidity measured by the temperature and humidity sensor 33 reaches the upper and lower limits, as control logic for controlling the air conditioning equipment (desiccant unit 11a, air conditioner 11b, humidifier, radiant heating and cooling device 30).

In the temperature settings illustrated in FIG. 11 , when the temperature reaches the upper limit during hot seasons such as summer (indicating a state in which the temperature in room 15 has risen and is hot), the air conditioner 11b and the radiant heating and cooling device 30 whose operation mode is set to cooling are turned on, and when the temperature reaches the lower limit (indicating a state in which the temperature in room 15 has dropped too low), the air conditioner 11b and the radiant heating and cooling device 30 whose operation mode is set to cooling are turned off.
On the other hand, during cold seasons such as winter, when the temperature reaches the upper limit (indicating a state in which the temperature inside the room 15 has risen too high), the air conditioner 11b and the radiant heating and cooling device 30 whose operation mode is set to heating are turned off, and when the temperature reaches the lower limit (indicating a state in which the temperature inside the room 15 has dropped and become cold), the air conditioner 11b and the radiant heating and cooling device 30 whose operation mode is set to heating are turned on.
Regarding the operating mode of the air conditioning equipment, the air conditioning equipment itself has an automatic operation function in which the operating mode is automatically selected according to the temperature inside the room 15 and the outdoor temperature, or the operating mode from the previous operation is automatically carried over.

In the relative humidity setting illustrated in FIG. 11, when the relative humidity in the room 15 is high and reaches the upper limit, the desiccant unit 11a is turned on to perform dehumidification, the humidifier is turned off, and the radiant heating and cooling device 30, whose operating mode is set to cooling, is also turned off to suppress the occurrence of condensation.
On the other hand, when the relative humidity in the room 15 is low, when the relative humidity reaches a lower limit, the humidifier is turned on and the radiant heating and cooling device 30, whose operating mode is set to cooling, is also turned on to suppress the occurrence of condensation, and the desiccant unit 11a is turned off to stop dehumidification.

In the absolute humidity setting illustrated in FIG. 11, when the absolute humidity in the room 15 is high and reaches the upper limit, the desiccant unit 11a is turned on to perform dehumidification, the humidifier is turned off, and the radiant heating and cooling device 30, whose operating mode is set to cooling, is also turned off to suppress the occurrence of condensation.
On the other hand, during periods when the absolute humidity in the room 15 is low, when the absolute humidity reaches a lower limit, the humidifier is turned on and the radiant heating and cooling device 30, whose operating mode is set to cooling, is also turned on to resume operation (to prevent condensation), and the desiccant unit 11a is turned off to stop dehumidification.

As in the above embodiment, the control logic can be set by the control unit 35, which is the controller, or the mobile information terminal 36. Therefore, in this modified example, as in the above embodiment, it is possible to set two control logics, "Logic 1" and "Logic 2," as described above, from among the control logics from "0" to "12."
The control unit 35, which is the controller, can combine control of the air conditioning equipment in terms of temperature, control of the air conditioning equipment in terms of relative humidity, and control of the air conditioning equipment in terms of absolute humidity, as shown in Figures 12 and 13.

FIG. 12 shows that the operation of the radiant heating and cooling device 30 is controlled so that it is turned off when the absolute humidity reaches an upper limit value and turned on when it reaches a lower limit value, and after the lower limit value is reached and the device is turned on, the device is turned on when the temperature reaches the upper limit value and turned off when the temperature reaches the lower limit value.
In other words, when the absolute humidity in the room 15 is low and the temperature is high, the radiant heating and cooling device 30 continues to operate on, and when the absolute humidity in the room 15 is high or the temperature is low, the radiant heating and cooling device 30 is turned off.

FIG. 13 shows that the operation of the desiccant unit 11a is controlled so that it is turned on when the temperature reaches an upper limit value and turned off when the temperature reaches a lower limit value, and after the upper limit value is reached and the desiccant unit 11a is turned on when the relative humidity reaches an upper limit value and turned off when the relative humidity reaches a lower limit value.
In other words, when the temperature in the room 15 is high and the relative humidity is high, the desiccant unit 11a continues to operate on, and when the temperature in the room 15 is low or the relative humidity is low, the desiccant unit 11a is turned off.

According to this modified example, the same effects as those of the above embodiment are achieved, and one or more of the following air conditioning equipment are used: a radiant heating and cooling device 30 provided inside the wall 21 constituting the target room 15; an air conditioner 11b capable of adjusting the temperature and humidity of the target room 15; a dehumidifier 11a capable of dehumidifying the target room 15; and a humidifier capable of humidifying the target room 15. Therefore, the target room 15 can be air-conditioned according to various control logics according to the type of equipment used as the air conditioning equipment.

Therefore, when the inside of the target room 15 is about to become an environment where condensation is likely to occur, the operating state of the air conditioning equipment 30 (11a, 11b) can be controlled according to the control logic. This makes it possible to air-condition the target room 15 while effectively suppressing the occurrence of condensation on the walls 21 to 24 of the target room 15.
The second invention is characterized in that, as shown in Figures 6, 11, etc., in the air conditioning system of the first invention, the operating state of the air conditioning equipment 30 (11a, 11b) is set to switch the operation of the air conditioning equipment 30 (11a, 11b) on and off when the temperature and/or humidity measured by the temperature and humidity sensor 33 reaches the upper limit value and the lower limit value.
According to the second invention, when the temperature and/or humidity measured by the temperature and humidity sensor 33 reaches the upper or lower limit, the operation of the air conditioning equipment 30 (11a, 11b) can be switched on and off. Therefore, the air conditioning equipment 30 (11a, 11b) can be turned on according to the measurement results of the temperature and humidity sensor 33 to air-condition the target room 15 while suppressing the occurrence of condensation, and when it is not necessary, the operation of the air conditioning equipment 30 (11a, 11b) can be turned off to reduce running costs.
The third invention is characterized in that, as shown in FIG. 9, in the air conditioning system of the second invention, the controller 35 is capable of setting a plurality of the control logics, and is capable of selecting whether to control the air conditioning equipment 30 (11a, 11b) according to any one of the plurality of control logics, or to control the air conditioning equipment 30 (11a, 11b) by combining at least two or more control logics among the plurality of control logics.
According to the third aspect of the present invention, the controller 35 can select between controlling the air conditioning equipment 30 (11a, 11b) according to any one of a plurality of control logics, or controlling the air conditioning equipment 30 (11a, 11b) by combining at least two or more control logics among the plurality of control logics. Therefore, the controller 35 can select a suitable control logic from various variations to control the air conditioning equipment 30 (11a, 11b).
The fourth invention is characterized in that, as shown in Figures 12 and 13, for example, in the air conditioning system of the third invention, when the controller 35 controls the air conditioning equipment 30 (11a, 11b) by combining the at least two or more control logics, after controlling the operation of the air conditioning equipment 30 (11a, 11b) to be switched on and off according to a previous control logic among the at least two or more control logics, the controller 35 controls the operation of the air conditioning equipment 30 (11a, 11b) to be switched on and off according to a control logic different from the previous control logic.
According to the fourth invention, the controller 35 first controls the operation of the air conditioning equipment 30 (11a, 11b) to be switched on and off according to a previous control logic among at least two or more control logics, and then controls the operation of the air conditioning equipment 30 (11a, 11b) to be switched on and off according to a control logic different from the previous control logic. Therefore, the operation of the air conditioning equipment 30 (11a, 11b) can be controlled by prioritizing the multiple control logics.
A fifth invention is characterized in that, as shown in Figures 6 to 12, for example, in an air conditioning system of any of the second to fourth inventions, the controller 35 calculates the absolute humidity of the target room 15 from the temperature and humidity measured by the temperature and humidity sensor 33, turns off the operation of the air conditioning equipment 30 (11a, 11b) when the calculated absolute humidity exceeds the upper limit value, and turns on the operation of the air conditioning equipment 30 (11a, 11b) when the calculated absolute humidity falls below the lower limit value.
According to the fifth invention, the controller 35 calculates the absolute humidity of the target room 15 from the temperature and humidity measured by the temperature and humidity sensor 33, turns off the operation of the air conditioning equipment 30 (11a, 11b) when the calculated absolute humidity exceeds an upper limit value, and turns on the operation of the air conditioning equipment 30 (11a, 11b) when the calculated absolute humidity falls below a lower limit value. Therefore, it is possible to air-condition the target room 15 while effectively suppressing the occurrence of condensation on the walls 21-24 of the target room 15, especially during periods of high temperature such as summer.
