Description

[Technical field]

[0001] The present invention relates to a condensation suppression system and a program for suppressing condensation that occurs on the surface of a wall material in a space within a partition wall adjacent to a living room separated by the partition wall. [Background technology]

[0002] In the air conditioning system described in Patent Document 1, outside air is supplied and exhausted between the rooms in the air-conditioned space and adjacent rooms that are not directly air-conditioned, thereby suppressing the occurrence of condensation in the rooms that are not directly air-conditioned. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7321379 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in a living room of a house, there is a space within a partition wall. For example, electrical wiring and the like are located in the space within the partition wall. In addition, the space within the partition wall may be connected to the outdoors via an air vent or the like. When warm and humid air from the outdoors in summer enters the space within the partition wall and comes into contact with the wall material that constitutes the partition wall, which is cooled by an air conditioner, condensation may occur on the surface of the wall material.

[0005] The present invention has been made in consideration of the above problems, and has an object to provide a condensation suppression system and program for suppressing the occurrence of condensation in a space within a wall. [Means for solving the problem]

[0006] (1) A condensation suppression system according to the present invention includes a room, a partition wall having a wall material that divides the room, a temperature sensor that acquires a surface temperature of the wall material in an interior space of the partition wall, an in-wall temperature and humidity sensor that acquires the temperature and relative humidity in the interior space of the partition wall, an air conditioner that adjusts the room temperature of the room by blowing air into the room, and a controller that controls the air direction of the air conditioner. The controller executes an in-wall dew point temperature calculation process that calculates a dew point temperature based on the room temperature and relative humidity acquired by the in-wall temperature and humidity sensor, and an air direction control process that controls the air direction of the air conditioner so that the air direction is not directed toward the partition wall by limiting an operating range of the air direction, on condition that the dew point temperature is higher than the surface temperature.

[0007] When the dew point temperature in the interior space of the partition wall is higher than the surface temperature of the wall material, the airflow direction of the air conditioner is controlled not to be directed toward the partition wall. This prevents the wall material from being cooled by the airflow sent from the air conditioner. By preventing a decrease in the surface temperature of the wall material, condensation on the surface of the wall material is prevented.

[0008] (2) After executing the airflow direction control process, the controller may further execute a temperature increase process to increase the temperature of air blown out from the air conditioning device, on condition that the dew point temperature is higher than the surface temperature.

[0009] By increasing the temperature of the blown air, the surface temperature of the wall material increases, which suppresses condensation on the surface of the wall material.

[0010] (3) The condensation suppression system further includes a through hole penetrating the wall material to communicate with an interior space of the partition wall and the living room, a differential pressure sensor acquiring a difference between an air pressure in the interior space of the partition wall and an outdoor air pressure, and a first fan located in an opening of an exterior wall separating the living room from the outdoors. After performing the air direction control process, the controller may further perform a first fan control process to drive the first fan to introduce outside air from the outdoors into the living room, on condition that the dew point temperature is higher than the surface temperature and the pressure in the outdoors is higher than the interior space of the partition wall.

[0011] By introducing outside air into the living room using the first fan located on the exterior wall, the inside of the living room becomes a positive pressure relative to the outdoors and the internal space of the partition wall. Air dried (dehumidified) by the air conditioning unit flows into the internal space of the partition wall through the through holes, preventing outside air from flowing into the internal space of the partition wall. The dew point temperature in the internal space of the partition wall is lowered, preventing condensation on the surface of the wall material.

[0012] (4) The condensation suppression system further includes an living room room humidity sensor that acquires a room temperature and a relative humidity in the living room, and a second fan located in the opening of the partition wall. The controller may further execute a living room absolute humidity calculation process that calculates an absolute humidity in the living room based on the room temperature and relative humidity acquired by the living room room humidity sensor, an intra-wall absolute humidity calculation process that calculates an absolute humidity in an interior space of the partition wall based on the room temperature and relative humidity acquired by the intra-wall temperature and humidity sensor, and a second fan control process that, after executing the first fan control process, drives the second fan to introduce air from the living room into the interior space of the partition wall, on condition that the dew-point temperature is higher than the surface temperature and the absolute humidity in the living room is lower than the absolute humidity in the interior space of the partition wall.

[0013] Since the air in the living room, which has a lower absolute humidity than the internal space of the partition wall, flows into the internal space of the partition wall, the absolute humidity in the internal space of the partition wall decreases. The decrease in absolute humidity in the internal space of the partition wall suppresses condensation on the surface of the wall material.

[0014] (5) The condensation prevention system further includes an outdoor air temperature and humidity sensor that acquires the temperature and relative humidity of the outdoor air. The controller executes an outdoor air absolute humidity calculation process that calculates the absolute humidity of the outdoor air based on the temperature and relative humidity acquired by the outdoor air temperature and humidity sensor, an outdoor air dew point temperature calculation process that calculates the dew point temperature of the outdoor air based on the temperature and relative humidity acquired by the outdoor air temperature and humidity sensor, and an intra-wall absolute humidity calculation process that calculates the absolute humidity in the interior space of the partition wall based on the room temperature and relative humidity acquired by the intra-wall temperature and humidity sensor, and may execute the wind direction control process under the condition that the absolute temperature of the outdoor air is higher than the absolute temperature in the interior space of the partition wall and the dew point temperature of the outdoor air is higher than the surface temperature.

[0015] When the absolute humidity of the outside air is higher than the absolute humidity in the internal space of the partition wall and the dew point temperature of the outside air is higher than the surface temperature of the wall material of the partition wall, the airflow direction of the air conditioner is controlled so as not to be directed toward the partition wall. In a situation where condensation occurs due to the inflow of outside air into the internal space of the partition wall, it is possible to prevent the air sent out from the air conditioner from being directed toward the partition wall in advance, thereby suppressing condensation on the surface of the wall material.

[0016] (6) The condensation suppression system may further include a wind speed sensor located on a surface of the wall material facing the living room and configured to acquire a wind speed on the surface of the partition wall facing the living room. In the wind direction control process, the controller may control the direction of the wind from the air conditioner toward the partition wall so that the wind speed acquired by the wind speed sensor is equal to or lower than a predetermined value.

[0017] By obtaining the wind speed on the surface of the wall material facing the living room, the direction of the air from the air conditioning unit can be controlled so that it is not directed toward the partition wall.

[0018] (7) The program of the present invention is a program for operating as a condensation prevention system comprising a living room, a partition wall having a wall material that divides the living room, a temperature sensor that acquires the surface temperature of the wall material in the interior space of the partition wall, an in-wall temperature and humidity sensor that acquires the room temperature and relative humidity in the interior space of the partition wall, an air conditioning unit that blows air into the living room to adjust the room temperature of the living room, and a controller that controls the air direction of the air conditioning unit, and causes the controller to execute an in-wall dew point temperature calculation process that calculates a dew point temperature based on the room temperature and relative humidity acquired by the in-wall temperature and humidity sensor, and an air direction control process that controls the air direction of the air conditioning unit so that the air direction is not directed toward the partition wall by limiting the operating range of the air direction, provided that the dew point temperature is higher than the surface temperature. Effect of the Invention

[0019] According to the present invention, it is possible to provide a condensation suppression system and a program for suppressing the occurrence of condensation in a space inside a wall. [Brief description of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings as appropriate. Note that the embodiment described below is merely an example of how the present invention is embodied, and it goes without saying that the embodiment can be appropriately modified without departing from the gist of the present invention.

[0022] Hereinafter, the directions related to the condensation suppression system 1 are indicated as a vertical direction 7, a front-rear direction 8, and a left-right direction 9. The front-rear direction 8 and the left-right direction 9 are all perpendicular to the vertical direction 7 and perpendicular to each other. The vertical direction 7 is the direction in which the partition wall 11 stands, and is the direction from the floor board 101 to the top board 102 of the living room 10. The left-right direction 9 is the direction along the floor board 101 of the living room 10 and the direction along the surfaces of the wall materials 111, 112 of the partition wall 11. The front-rear direction 8 is the direction perpendicular to the surfaces of the wall materials 111, 112 of the partition wall 11, and is the thickness direction of the wall materials 111, 112.

[0023] [Installation of Condensation Suppression System 1] As shown in Fig. 1 and Fig. 2, the condensation suppression system 1 suppresses condensation on the surface of a wall material 111 in a building, which occurs due to cooling by an air conditioner 14 used in the summer, for example. A building is a structure whose interior is divided by partition walls. The condensation suppression system 1 can be used in buildings such as detached houses, apartment buildings, and commercial facilities. The condensation suppression system 1 includes a room 10, a partition wall 11, a temperature sensor 12, an in-wall temperature and humidity sensor 13, an air conditioner 14, a through hole 16, a differential pressure sensor 17, a first fan 18, a room temperature and humidity sensor 19, a second fan 20, an outside temperature and humidity sensor 21, a wind speed sensor 22, and a controller 15 (see Fig. 6).

[0024] As shown in FIG. 1, the living room 10 is, for example, a rectangular room. In this embodiment, a living room on the first floor of a detached house is described as an example. The living room is partitioned by a floor board 101, a top board 102, and four walls (a front wall 103, a rear wall 104, a right wall 105, and a left wall 106). The floor board 101 of the living room 10 is attached to a joist (not shown), and an underfloor space is located below the floor board 101. The underfloor space is configured to be able to introduce outside air from the outdoors, for example, using a vent hole (not shown). The top board 102 of the living room 10 is attached to a rafter that is hung from a beam using a hanging tree (not shown), for example. A space is located above the top board 102. The space above the top board 102 is configured to be able to introduce outside air from the outdoors, for example, using a vent hole (not shown).

[0025] In the present embodiment, the front wall 103 and the left wall 106 are exterior walls. The outer surfaces of the front wall 103 and the left wall 106 face the outdoors. The front wall 103 has an opening 31 (see FIG. 2) penetrating through the thickness direction. The rear wall 104 and the right wall 105 are partition walls 11 that separate the room 10 from other rooms, corridors, etc. within the building.

[0026] The partition wall 11 is constructed by combining studs with runners fixed to a floor board 101 and a top board 102 in a frame body (not shown). The partition wall 11 has a structure in which a pair of wall materials 111, 112 (plaster board, wallpaper, etc.) are attached to both sides (front and rear) of the frame body. Between the pair of wall materials 111, 112, a space having a width equal to the thickness of the frame body is located, for accommodating electrical wiring, optical wiring, etc. Hereinafter, this space is also referred to as an internal space 100.

[0027] An opening 110 that communicates the internal space 100 with the space above the top plate 108 is located in the top plate 108 of the internal space 100 and in the runner located above it. Electric wiring, optical wiring, and the like are located in the opening 110. In addition, an opening 109 that communicates the internal space with the space under the floor is located in the floor plate 107 of the internal space and in the runner located below it. Pipes, and the like are located in the opening 109. The opening 109 also functions as an air hole that passes air between the outdoors and the internal space 100 via the space under the floor or the space above the top plate.

[0028] 1 shows a pair of wall materials 111, 112 and the internal space 100 for the rear wall 104. On the other hand, the pair of wall materials 111, 112 and the internal space 100 for the right wall 105 are not shown. An opening 161 for entering and exiting the living room 10 is located in the right wall 105. A door 162 is located in the opening 161.

[0029] The temperature sensor 12 is located in the internal space 100 of the partition wall 11. The temperature sensor 12 is located, for example, on the surface (the surface facing rearward) of the wall material 111. The temperature sensor 12 acquires the surface temperature of the wall material 111 located in front, and outputs an electrical signal according to the acquired surface temperature. The temperature sensor 12 is, for example, a sensor that measures the resistance value of a resistor that changes with temperature, an infrared sensor, or the like.

[0030] The in-wall temperature and humidity sensor 13 is located in the internal space 100 of the partition wall 11. The in-wall temperature and humidity sensor 13 acquires the temperature and relative humidity of the air located in the internal space 100, and outputs an electrical signal according to the acquired relative humidity. The in-wall temperature and humidity sensor 13 is a combination of a temperature sensor and a humidity sensor. The humidity sensor may be a resistance-type humidity sensor that detects moisture adsorbed and desorbed by a moisture-sensitive material as electrical resistance, or a capacitance-type humidity sensor that detects moisture adsorbed and desorbed by a moisture-sensitive material as electrostatic capacitance, etc.

[0031] The air conditioner 14 is a so-called air conditioner. The air conditioner 14 is a device that adjusts the room temperature of the room 10 by blowing wind (cold wind) into the room 10 through heat exchange between the outside air and the refrigerant. The air conditioner 14 is located in the room 10. In this embodiment, the air conditioner 14 is fixed to an upper part of the left wall 106 in the room 10. As shown in FIG. 3, the air conditioner 14 is configured to be able to change the wind direction of the air that is blown out. The air conditioner 14 is configured to be able to change the wind direction of the air that is blown out, for example, by changing the angle of a louver (not shown). In addition, the air conditioner 14 is configured to be able to change the temperature of the air that is blown out. The air conditioner 14 is configured to be able to change the temperature of the air that is blown out, for example, by adjusting the compression amount of the refrigerant.

[0032] The through-hole 16 penetrates the front wall material 111 in the partition wall 11 to communicate between the living room 10 and the internal space 100. In this embodiment, the through-hole 16 is, for example, a hole to which the outlet panel 41 is attached.

[0033] The differential pressure sensor 17 is located, for example, in the internal space 100 of the partition wall 11. The differential pressure sensor 17 acquires a differential pressure between the air in the internal space 100 and the outside air adjacent to the internal space 100 via the opening 109, and outputs an electrical signal according to the acquired differential pressure. The differential pressure sensor 17 acquires, for example, the pressure of the air in the internal space 100 and the pressure of the outside air, and calculates the difference therebetween, thereby acquiring the differential pressure.

[0034] The first fan 18 is located in an opening 31 (see FIG. 2) in an exterior wall (front wall 103) that separates the living room 10 from the outdoors. The first fan 18 is a so-called ventilation fan. As shown in FIG. 4, the first fan 18 can introduce air from the outdoors into the living room 10 by rotating.

[0035] The living room temperature and humidity sensor 19 is located in the living room 10. The living room temperature and humidity sensor 19 acquires the room temperature and relative humidity in the living room 10, and outputs an electrical signal according to the acquired room temperature and relative humidity. The in-wall temperature and humidity sensor 13 is a combination of a temperature sensor and a humidity sensor.

[0036] The second fan 20 is located at an opening 32 in a wall material 111 on the living room 10 side of the partition wall 11. The second fan 20 is a so-called ventilation fan. As shown in Fig. 5, the second fan 20 can introduce air from the living room 10 into the interior space 100 by rotating.

[0037] The outside temperature and humidity sensor 21 is located outside the living room 10. The outside temperature and humidity sensor 21 is located, for example, on the outer surface of the front wall 103. The outside temperature and humidity sensor 21 acquires the temperature and relative humidity of the outside air, and outputs an electrical signal according to the acquired temperature and relative humidity. The outside temperature and humidity sensor 21 is a combination of a temperature sensor and a humidity sensor.

[0038] The wind speed sensor 22 is located in the living room 10, on the surface of the wall material 111 facing the living room 10 (the surface facing forward). For example, a plurality of wind speed sensors 22 are located on the surface of the wall material 111. The wind speed sensor 22 obtains the wind speed by converting the change in resistance value into wind speed using a resistor whose resistance value changes depending on temperature, and outputs an electrical signal according to the obtained wind speed. A plurality of wind speed sensors 22 may be located on the surface of the wall material 111.

[0039] A controller 15 is disposed in the living room 10. As shown in Fig. 6, the controller 15 includes a CPU 151, a ROM 152, a RAM 153, an EEPROM 154, an ASIC 155, and the like, which are connected via a bus so as to enable data communication. The CPU 151 executes a program stored in the ROM 152, and the ASIC 155 performs a specific function set therein, thereby controlling the operation of the condensation suppression system 1. The controller 15 is electrically connected to the temperature sensor 12, the wall temperature and humidity sensor 13, the air conditioner 14, the differential pressure sensor 17, the living room room temperature and humidity sensor 19, the outside temperature and humidity sensor 21, the wind speed sensor 22, and the motors 23 and 24.

[0040] The EEPROM 154 stores a preset temperature of the living room 10 when the air conditioner 14 operates. The EEPROM 154 stores wind direction information, which is information on the wind direction of the wind sent out from the air conditioner 14, in a wind direction control process described later. The EEPROM 154 stores a target value of the temperature when changing the temperature sent out from the air conditioner 14. The EEPROM 154 stores a program for wind direction control process for controlling the wind direction of the wind sent out from the air conditioner 14. The EEPROM 154 stores a program for temperature control process for controlling the temperature of the wind sent out from the air conditioner 14. The EEPROM 154 stores programs for first fan control process and second fan control process for controlling the operation of the motors 23, 24 to control the first fan 18 and the second fan 20. The EEPROM 154 stores a target value for increasing the room temperature of the living room 10, variables W, P1, P2, P3, P4, etc., which are set in the temperature control process. The EEPROM 154 stores a relational expression for saturated water vapor pressure calculated based on temperature. The EEPROM 154 stores a relational expression for water vapor pressure in air calculated based on saturated water vapor pressure and relative humidity. The EEPROM 154 stores a relational expression for dew point temperature based on water vapor pressure in air. The EEPROM 154 stores a relational expression for saturated water vapor amount based on saturated water vapor pressure and temperature. The EEPROM 154 stores a predetermined value used as a threshold value for wind speed in the wind direction control process.

[0041] Here, the wind direction information is information on the wind direction that is set in advance so as to prevent wind from the air conditioner 14 from blowing directly toward the position of the wall material 111 of the partition wall 11. The wind direction information is, for example, information indicating the horizontal movable range M within which the wind direction of the air conditioner 14 can be changed (for example, the range indicated by the limit positions A1 and A2 of the changeable angle in FIG. 3), as shown in FIG. 3. The wind direction information includes multiple movable ranges in which the limit position A1 on the side closer to the partition wall 11 is brought closer to the limit position A2 on the side farther from the partition wall 11. In other words, the wind direction information includes information on multiple movable ranges in which the movable range M is gradually reduced without changing the position of the limit position A2. For example, as shown in FIG. 3, the wind direction information includes information on a movable range M having limit positions A1 and A2, a movable range M1 in which limit position A1 is moved to limit position A3, a movable range M2 in which limit position A1 is moved to limit position A4, and information on multiple movable ranges in which limit position A1 exceeds limit position A4 and gradually approaches A2 to narrow the movable range.

[0042] The target value for increasing the room temperature of the room 10 is a value that indicates the increase range of the set temperature of the air conditioner 14. The target value for increasing the room temperature of the room 10 is a predetermined value, for example, +0.5°C, +1°C, or the like.

[0043] The variable W is an integer and corresponds to each of a plurality of movable ranges. The variable W is used when selecting a movable range. The variable W has an initial value of 0.

[0044] The variables P1, P2, P3, and P4 are integers. The variables P1, P2, P3, and P4 indicate the implementation status of the airflow direction control process, the temperature rise control process, the first fan control process, and the second fan control process, which will be described later. The variables P1, P2, P3, and P4 all have an initial value of 0.

[0045] The controller 15 may be one in which various processes are executed only by the CPU 151. The controller 15 may be one in which various processes are executed only by the ASIC 155. The controller 15 may be implemented with a plurality of CPUs 151 that share and execute each process. The controller 15 may be implemented with a plurality of ASICs 155 that share and execute each process.

[0046] [Operation of Condensation Suppression System 1] Next, the operation of the condensation suppression system 1 will be described with reference to the flowcharts of FIGS. 7, first, the controller 15 judges whether or not the operation of the air conditioner 14 has started (step S1). If the operation of the air conditioner 14 has started (step S1_YES), the process proceeds to step S2. If the operation of the air conditioner 14 has not started (step S1_NO), the process of the condensation suppression system 1 ends. The air conditioner 14 operates while controlling the air volume, air speed, etc., based on the set temperature of the room 10 stored in the EEPROM 154, for example.

[0047] In step S2, the controller 15 acquires the surface temperature of the wall material 111 of the partition wall 11 by receiving an electrical signal corresponding to the temperature acquired by the temperature sensor 12. The controller 15 acquires the air temperature and relative humidity of the interior space 100 by receiving an electrical signal from the intra-wall temperature and humidity sensor 13 (step S3). Thereafter, the controller 15 executes a pre-reduction process, which will be described later (step S4). After the pre-reduction process, the process proceeds to step S5.

[0048] In step S5, the controller 15 calculates the dew point temperature of the internal space 100 based on the acquired air temperature and relative humidity of the internal space 100. The dew point temperature is calculated, for example, as follows. The controller 15 reads out the relational expression of the saturated water vapor pressure from the EEPROM 154. The controller 15 substitutes the temperature of the air of the internal space 100 into the relational expression of the saturated water vapor pressure to calculate the saturated water vapor pressure. The controller 15 reads out the relational expression of the water vapor pressure in the air from the EEPROM 154. The controller 15 substitutes the calculated saturated water vapor pressure and the relative humidity of the internal space 100 into the relational expression of the water vapor pressure in the air to calculate the water vapor pressure in the air. The controller 15 acquires the relational expression of the dew point temperature from the EEPROM 154. The controller 15 substitutes the calculated water vapor pressure into the relational expression of the dew point temperature to calculate the dew point temperature.

[0049] The controller 15 judges whether the surface temperature of the wall material 111 is lower than the calculated dew point temperature (step S6). If the surface temperature is lower than the dew point temperature (step S6_YES), the process proceeds to step S7. If the surface temperature is higher than the dew point temperature (step S6_NO), the process proceeds to step S17.

[0050] In step S7, the controller 15 judges whether or not the airflow direction control process of the air conditioner 14 has already been performed. That is, the controller 15 judges whether or not the process of step S11 has been performed. The controller 15 reads the variable P1 from the EEPROM 154. If the variable P1 is 0, the controller 15 judges that the airflow direction control process has not been performed. If the variable P1 is 1, the controller 15 judges that the airflow direction control process has been performed. If the airflow direction control process has been performed (step S7_YES), the process proceeds to step S8. If the airflow direction control process has not been performed (step S7_NO), the process proceeds to step S11.

[0051] In step S11, the controller 15 executes a wind direction control process. The details of the wind direction control process will be described later. The process proceeds to step S16.

[0052] In step S8, the controller 15 determines whether or not the temperature control process has already been performed. That is, the controller 15 determines whether or not the process of step S12 has been performed. The controller 15 acquires a variable P2 from the EEPROM 154. If the variable P2 is 0, the controller 15 determines that the temperature control process has not been performed. If the variable P2 is 1, the controller 15 determines that the temperature control process has been performed. If the temperature control process has been performed (step S8_YES), the process proceeds to step S9. If the temperature control process has not been performed (step S8_NO), the process proceeds to step S12.

[0053] In step S12, the controller 15 performs a temperature control process. The controller 15 acquires from the EEPROM 154 the set temperature of the room 10 and a target value, which is an increase amount by which the room temperature of the room 10 is increased. The controller 15 sets the temperature obtained by adding the acquired target value to the room temperature of the room 10 as a new set temperature of the air conditioner 14. The controller 15 operates the air conditioner 14 based on the new set temperature, thereby increasing the temperature of the air sent out from the air conditioner 14. The air conditioner 14 increases the temperature of the air sent out by, for example, adjusting the amount of compression of the refrigerant based on the set temperature. After that, the controller 15 increments the variable P2 and stores it in the EEPROM 154 (step S13). The process then proceeds to step S16.

[0054] In step S9, the controller 15 determines whether the first fan 18 has been operated. That is, the controller 15 determines whether the process of step S14 has been performed. The controller 15 acquires a variable P3 from the EEPROM 154. If the variable P3 is 0, the controller 15 determines that the first fan control process has not been performed. If the variable P3 is 1, the controller 15 determines that the first fan control process has been performed. If the control process has been performed on the first fan 18 (step S9_YES), the process proceeds to step S10. If the first fan control process has not been performed (step S9_NO), the process proceeds to step S14.

[0055] In step S14, the controller 15 executes a first fan control process. The first fan control process will be described in detail later. After that, the process proceeds to step S16.

[0056] In step S10, the controller 15 determines whether or not the second fan control process has been performed. That is, the controller 15 determines whether or not the process of step S15 has been performed. The controller 15 acquires a variable P4 from the EEPROM 154. If the variable P4 is 0, the controller 15 determines that the second fan control process has not been performed. If the variable P4 is 1, the controller 15 determines that the second fan control process has been performed. If the second fan control process has been performed (step S10_YES), the process proceeds to step S15. If the second fan control process has not been performed (step S10_NO), the process proceeds to step S16.

[0057] In step S15, the controller 15 executes a second fan control process. The second fan control process will be described in detail later. Then, the process proceeds to step S16.

[0058] In step S16, the controller 15 judges whether a predetermined time has elapsed since the end of the airflow direction control process, the temperature control process, the first fan control process, or the second fan control process. Here, the controller 15 waits until the airflow direction control process, the temperature control process, the first fan control process, and the second fan control process are expected to have an effect on the surface temperature. The waiting time is preset within a range of, for example, 5 to 10 minutes. If the waiting time has elapsed (step S16_YES), the process proceeds to step S19. If the waiting time has not elapsed (step S16_NO), step S16 is repeated until the waiting time has elapsed.

[0059] In step S17, the controller 15 judges whether or not there is an active control. Specifically, the controller 15 judges whether or not there is any variable among the variables P1, P2, P3, and P4 in which 0 is not stored. If there is an active control (step S17_YES), the process proceeds to step S18. If there is no active control (step S17_NO), the process proceeds to step S19.

[0060] In step S18, the controller 15 stops all controls that are in progress. The controller 15 resets the variables W, P1, P2, P3, and P4 (sets them to the numerical value "0"), and stores the variables W, P1, P2, P3, and P4 in the EEPROM 154. The process proceeds to step S19.

[0061] In step S19, the controller 15 judges whether or not the air conditioner 14 is stopped. If the air conditioner 14 is stopped (step S19_YES), the process proceeds to step S20. If the air conditioner 14 is not stopped (step S19_NO), the process returns to step S2.

[0062] In step S20, the controller 15 stops all controls that are in progress. The controller 15 resets the variables W, P1, P2, P3, and P4, and stores the variables W, P1, P2, P3, and P4 in the EEPROM 154. This ends the processing of this flow.

[0063] [Pre-inhibition processing] Next, the flow of the advance suppression process will be described with reference to the flowchart in Fig. 8. The advance control process is a process in which the condensation suppression system 1 performs an operation to make it difficult for condensation to occur in advance in a situation where the dew point temperature of the outside air rises and condensation is likely to occur on the surface of the wall material 111 of the partition wall 11.

[0064] The controller 15 acquires the temperature and relative humidity of the outside air based on the electrical signal received from the outside air temperature and humidity sensor 21 (step S41). The controller 15 calculates the absolute humidity of the outside air from the acquired temperature and relative humidity of the outside air (step S42). The absolute humidity is calculated, for example, as follows. First, the controller 15 reads out from the EEPROM 154 a relational expression of the saturated water vapor pressure calculated based on the temperature. The controller 15 calculates the saturated water vapor pressure by substituting the temperature of the outside air into the read relational expression of the saturated water vapor pressure. The controller 15 reads out from the EEPROM 154 a relational expression of the amount of saturated water vapor based on the saturated water vapor pressure and the temperature. The controller 15 calculates the amount of saturated water vapor by substituting the calculated saturated water vapor pressure and the temperature of the outside air into the relational expression of the amount of saturated water vapor. The controller 15 calculates the product of the calculated amount of saturated water vapor and the relative humidity of the outside air as the absolute humidity.

[0065] The controller 15 calculates the dew point temperature of the outside air from the acquired temperature and relative humidity of the outside air (step S43). The dew point temperature is obtained, for example, as follows. The controller 15 reads out the relational equation of the saturated water vapor pressure from the EEPROM 154. The controller 15 calculates the saturated water vapor pressure by substituting the temperature of the outside air into the relational equation of the saturated water vapor pressure. The controller 15 reads out the relational equation of the water vapor pressure in the air from the EEPROM 154. The controller 15 calculates the water vapor pressure in the air by substituting the calculated saturated water vapor pressure and the relative humidity of the outside air into the relational equation of the water vapor pressure in the air. The controller 15 obtains the relational equation of the dew point temperature from the EEPROM 154. The controller 15 calculates the dew point temperature by substituting the calculated water vapor pressure into the relational equation of the dew point temperature.

[0066] The controller 15 calculates the absolute humidity of the internal space 100 from the acquired temperature and relative humidity of the internal space 100 (step S44). The absolute humidity is calculated, for example, as follows. First, the controller 15 reads out from the EEPROM 154 a relational expression of the saturated water vapor pressure calculated based on the temperature. The controller 15 calculates the saturated water vapor pressure by substituting the temperature of the internal space 100 into the read-out relational expression of the saturated water vapor pressure. The controller 15 reads out from the EEPROM 154 a relational expression of the amount of saturated water vapor based on the saturated water vapor pressure and the temperature. The controller 15 calculates the amount of saturated water vapor by substituting the calculated saturated water vapor pressure and the temperature of the internal space 100 into the relational expression of the amount of saturated water vapor. The controller 15 calculates the product of the calculated amount of saturated water vapor and the relative humidity of the internal space 100 as the absolute humidity.

[0067] The controller 15 determines whether the absolute humidity of the outside air is equal to or higher than the absolute humidity of the internal space 100 (step S45). If the absolute humidity of the outside air is equal to or higher than the absolute humidity of the internal space 100 (step S45_YES), the process proceeds to step S46. If the absolute humidity of the outside air is lower than the absolute humidity of the internal space 100, the pre-control process ends.

[0068] In step S46, the controller 15 judges whether the dew point temperature of the outside air is equal to or higher than the surface temperature of the wall material 111 of the partition wall 11 (step S47). If the dew point temperature of the outside air is equal to or higher than the surface temperature (step S47_YES), the process proceeds to step S47. If the dew point temperature of the outside air is lower than the surface temperature (step S47_NO), the pre-control process ends.

[0069] In step S47, since the situation is such that condensation will occur due to the inflow of outside air into the internal space 100, the controller 15 executes a wind direction control process. The details of the wind direction control process will be described later. With this, the pre-control process ends.

[0070] [Wind direction control processing] Next, the flow of the airflow direction control process will be described with reference to the flowchart in Fig. 9. The airflow direction control process is a process performed in the condensation suppression system 1 to control the direction of airflow sent out from the air conditioner 14, thereby preventing the airflow from hitting the wall material 111 of the partition wall 11. By preventing the airflow from directly hitting the wall material 111, cooling of the wall material 111 is suppressed.

[0071] The controller 15 acquires information on the direction of the wind to be directed by the air conditioner 14 (step S110). The controller 15 acquires information on the direction of the wind to be directed, for example, by reading out the wind direction information stored in the EEPROM 154.

[0072] The controller 15 acquires the variable W from the EEPROM 154 and controls the wind direction of the air conditioner 14 (step S111). The controller 15 selects the movable range included in the acquired wind direction information based on the value of the variable W. For example, when the variable W=0, the controller 15 selects the widest movable range (for example, the movable range M in FIG. 3). For example, each time the variable W increases by 1, the controller 15 selects an increasingly narrower movable range from the movable ranges included in the wind direction information (for example, when the variable W=1, the movable range M1). The controller 15 controls the wind direction of the air conditioner 14 based on the selected movable range.

[0073] The controller 15 acquires the wind speed based on the electrical signal received from the wind speed sensor 22 (step S112). The controller 15 judges whether the acquired wind speed is equal to or lower than a predetermined value (step S113). The predetermined value is acquired, for example, from the EEPOM 154. If the wind speed is equal to or lower than the predetermined value (step S113_YES), the wind sent out from the air conditioner 14 is not blowing against the wall material 111 of the partition wall 11, and the process proceeds to step S114. If the wind speed exceeds the predetermined value (step S113_NO), the wind sent out from the air conditioner 14 is blowing against the wall material 111 of the partition wall 11, and the process proceeds to step S115.

[0074] In step S114, the controller 15 increments the variable P1. The controller 15 stores the incremented variable P1 in the EEPROM 154. Then, the wind direction control process ends.

[0075] In step S115, the controller 15 increments the variable W. The controller 15 stores the incremented variable W in the EEPROM 154. Then, the process returns to step S111.

[0076] [First fan control process] Next, the first fan control process will be described with reference to the flowchart of Fig. 10. The first fan control process is a process for taking in outside air from the outdoors into the living room 10 by controlling the rotation direction of the first fan 18. By taking in the outside air into the living room 10, the living room 10 and the outdoors become positive pressure relative to the internal space 100. By making the living room 10 positive pressure relative to the internal space 100 and the outdoors, air flows from the living room 10 to the internal space 100 through the through-hole 16. Since the air in the living room 10 has been dried by the air conditioner 14, the dry air can be introduced into the internal space 100 to lower the relative humidity of the internal space 100.

[0077] The controller 15 acquires the difference between the air pressure in the internal space 100 of the partition wall 11 and the outdoor air pressure based on the electrical signal received from the differential pressure sensor 17 (step S141). The controller 15 determines whether the pressure in the internal space 100 is lower than the outdoor air pressure based on the acquired difference (step S142). If the pressure in the internal space 100 is lower than the outdoor air pressure (step S142_YES), the process proceeds to step S143. If the pressure in the internal space 100 is equal to or higher than the outdoor air pressure (step S144_NO), the first fan control process ends.

[0078] In step S143, the controller 15 starts the operation of the first fan 18. The controller 15 controls the rotation direction of the first fan 18 to take outside air into the living room 10. Then, the process proceeds to step S144.

[0079] In step S144, the controller 15 increments the variable P3. The controller 15 stores the incremented variable P3 in the EEPROM 154. Then, the first fan control process ends.

[0080] [Second fan control process] Next, the second fan control process will be described with reference to the flowchart of Fig. 11. The second fan control process is a process for controlling the rotation direction of the second fan 20 to send air from the living room 10 to the internal space 100 of the partition wall 11. By operating the second fan, the amount of air introduced from the living room 10 into the internal space 100 increases compared to when only the first fan is operating. By increasing the amount of air introduced into the internal space 100, the relative humidity of the internal space 100 can be further reduced.

[0081] The controller 15 acquires the room temperature and the relative humidity in the living room 10 based on the electrical signal received from the room temperature and humidity sensor 19 (step S151). The controller 15 calculates the absolute humidity in the living room 10 and the internal space 100 based on the acquired room temperature and relative humidity (step S152). The absolute humidity is calculated, for example, as follows. First, the controller 15 reads out from the EEPROM 154 a relational expression of the saturated water vapor pressure calculated based on the temperature. The controller 15 calculates the saturated water vapor pressure by substituting the room temperature of the living room 10 into the read relational expression of the saturated water vapor pressure. The controller 15 reads out from the EEPROM 154 a relational expression of the amount of saturated water vapor based on the saturated water vapor pressure and the temperature. The controller 15 calculates the amount of saturated water vapor by substituting the calculated saturated water vapor pressure and the room temperature into the relational expression of the amount of saturated water vapor. The controller 15 calculates the product of the calculated amount of saturated water vapor and the relative humidity of the internal space 100 as the absolute humidity.

[0082] The controller 15 judges whether the absolute humidity of the living room 10 is lower than the absolute humidity of the internal space 100 (step S153). If the absolute humidity of the living room 10 is lower than the absolute humidity of the internal space 100 (step S153_YES), the process proceeds to step S154. If the absolute humidity of the living room 10 is equal to or higher than the absolute humidity of the internal space 100 (step S153_NO), the second fan control process ends.

[0083] In step S154, the controller 15 starts the operation of the second fan 20. The controller 15 controls the rotation direction of the second fan 20 to send air from the room 10 into the internal space 100 of the partition wall 11.

[0084] The controller 15 increments the variable P4 (step S155). The controller 15 stores the incremented variable P4 in the EEPROM 154. Then, the second fan control process ends.

[0085] (Effects of the embodiment) When the dew point temperature in the internal space 100 of the partition wall 11 is higher than the surface temperature of the wall material 111, the airflow direction of the air conditioner 14 is controlled not to be directed toward the partition wall 11. This prevents the wall material 111 from being cooled by the airflow sent out from the air conditioner 14. By preventing a decrease in the surface temperature of the wall material 111, condensation on the surface of the wall material 111 is prevented.

[0086] Increasing the temperature of the air blown out from the air conditioner 14 increases the surface temperature of the wall material 111. Increasing the surface temperature of the wall material 111 suppresses condensation on the surface of the wall material 111. By controlling the air direction and increasing the temperature, condensation is more effectively suppressed.

[0087] By introducing outside air into the living room 10 using the first fan 18 located on the exterior wall, the inside of the living room 10 becomes a positive pressure relative to the outdoors and the internal space 100 of the partition wall 11. The air dried by the air conditioner 14 flows into the internal space 100 of the partition wall 11 through the through-holes 16, thereby suppressing the inflow of outside air into the internal space 100 of the partition wall 11. The dew point temperature in the internal space 100 of the partition wall 11 is lowered, suppressing condensation on the surface of the wall material 111. Condensation is more effectively suppressed by controlling the wind direction and operating the first fan 18.

[0088] Since the air in the living room 10, which has a lower absolute humidity than the internal space 100 of the partition wall 11, flows into the internal space 100 of the partition wall 11, the absolute humidity in the internal space 100 of the partition wall 11 decreases. The decrease in absolute humidity in the internal space 100 of the partition wall 11 suppresses condensation on the surface of the wall material 111. Since this is performed in conjunction with the control of the first fan 18, the amount of air flowing into the internal space 100 increases, effectively suppressing condensation.

[0089] When the absolute humidity of the outside air is higher than the absolute humidity in the internal space 100 of the partition wall 11 and the dew point temperature of the outside air is higher than the surface temperature of the wall material 111 of the partition wall 11, the airflow direction of the air conditioner 14 is controlled not to be directed toward the partition wall 11. In a situation in which condensation occurs due to the inflow of outside air into the internal space 100 of the partition wall 11, it is possible to prevent the air sent out from the air conditioner 14 from being directed toward the partition wall 11 in advance, thereby suppressing condensation on the surface of the wall material 111.

[0090] (Modification) In the above embodiment, the controller 15 acquires wind direction information indicating a predetermined movable range for the wind direction of the air conditioner 14, but this is not limited to the above. The EEPROM 154 may store directional information that predetermines the direction in which the partition wall 11 is located with respect to the air conditioner 14. The controller 15 may acquire the directional information and control the air conditioner 14 so that the wind direction is not directed toward the position of the partition wall 11 indicated in the directional information.

[0091] In the above embodiment, the controller 15 may linearly move the position of limit position A1 shown in Fig. 3 toward limit position A2 with respect to the wind direction of the air conditioner 14. The controller 15 may move the wind direction of the air conditioner 14 until the wind speed acquired by the wind speed sensor 22 becomes equal to or less than a predetermined value. This allows the wind direction to be controlled when the wind speed acquired by the wind speed sensor 22 becomes equal to or less than the predetermined value, thereby making it possible to ensure the comfort of the room as much as possible while widening the wind direction as much as possible and suppressing condensation.

[0092] In the above embodiment, the controller 15 may control the air volume to increase according to the amount of temperature increase during the temperature increase control process. The increase in the air volume can suppress the increase in the sensible temperature associated with the temperature increase control process. The target value of the temperature increase may be dynamically determined based on the dew point temperature of the internal space 100. For example, when the dew point temperature of the internal space 100 is higher than the room temperature, the controller 15 may determine the target value so that the sum of the room temperature and the target value is higher than the dew point temperature. The target value may be a plurality of values ​​that gradually increase. The controller 15 may first determine the set temperature of the air conditioner 14 using the smallest target value during the temperature increase control process. After a predetermined time has elapsed, when the surface temperature of the wall material 111 is still lower than the dew point temperature, the controller 15 may determine the set temperature of the air conditioner 14 using the next smallest target value. For example, the controller 15 may add the next smallest target value to the set temperature of the air conditioner 14 immediately before the temperature increase control process to determine a new set temperature.

[0093] The controller 15 may determine the target value to be used by, for example, applying a predetermined variable by incrementing it, similar to the variable W in the airflow direction control process. If all the target values ​​have been used and the surface temperature is still lower than the dew point temperature after a predetermined time has elapsed, the controller 15 may then proceed to step S9. Note that an upper limit value for the set temperature may be stored in the EEPROM 154 in advance. If the newly set temperature is higher than the upper limit value, the controller 15 may proceed to step S9 without determining the new set temperature. This makes it possible to prevent an excessive rise in the room temperature of the room 10 and maintain the comfort of the room 10.

[0094] In the above embodiment, when the air conditioner 14 is stopped, the control in operation is stopped, but this is not limited to the above. When the surface temperature is equal to or lower than the dew point temperature of the internal space 100, the controller 15 may continue to execute the first fan control process even when the air conditioner 14 is stopped. Furthermore, the controller 15 may continue to execute the second fan control process in addition to the first fan control process even when the air conditioner 14 is stopped. Furthermore, the controller 15 may stop the first fan control process and the second fan control process when the surface temperature becomes higher than the dew point temperature of the internal space 100.

[0095] In addition, in the pre-control process in the above embodiment, the wind direction control process is executed, but this is not limited to this. Instead of the wind direction control process, the temperature rise control process or the first fan control process may be executed. In addition to the wind direction control process, at least one of the temperature rise control process and the first fan control process may be executed. In addition to the first fan control process, the second fan control process may be executed. For example, depending on the rate at which the absolute humidity of the outside air increases, the controller 15 may increase the number of control processes to be executed. This allows for flexible response to suppress condensation depending on the expected increase in absolute humidity in the internal space 100 of the partition wall 11.

[0096] Also, as shown in FIG. 12, a roll screen 80 capable of unfolding a sheet in the vertical direction 7 may be located between the wall material 111 of the partition wall 11 and the air conditioner 14. The sheet 81 of the roll screen 80 is, for example, in a rolled-up state and located near the top plate 102. The sheet 81 is unfolded downward from the rolled-up state, and is stretched between the wall material 111 and the air conditioner 14. The sheet 81 has, for example, a position and width with respect to the wall material 111 that can block the wind sent out from the air conditioner 14. The controller 15 operates the roll screen to extend it in addition to or instead of the wind direction control process. This suppresses the wind from the air conditioner 14 blowing onto the wall material 111, and suppresses a decrease in the surface temperature of the wall material 111.

[0097] In the above embodiment, the temperature rise control process is performed before the first fan control process, but this is not limiting. The temperature rise control process may be performed after the first fan control process. The second fan control process may be performed either before or after the temperature rise control process, as long as it is performed after the first fan control process.
