[0027] (Embodiment)

[0028] [Overview of Indoor Environment Control System]

[0029] First, the overview of the indoor environment control system in the embodiment will be described. Figure 1 FIG. is a diagram showing the schematic structure of the indoor environment control system in the embodiment.

[0030] The indoor environment control system 500 is a system provided to cover the shower room S and the space R adjacent to the shower room. The indoor environment control system 500 is a system that suppresses a humid state in which bacteria such as molds easily multiply on the wall between the shower room S and the space R, thereby suppressing the reproduction of bacteria such as molds.

[0031] Here, it is not just to reduce the humidity in the hollow part (living space) of the shower room S and the space R, but to suppress the state in which moisture remains inside the wall and is difficult to reduce by ventilation etc., and to suppress the reproduction of bacteria such as molds on the wall that is difficult to suppress only by ventilation etc. In addition, the space described as the shower room S here refers to spaces such as bathrooms, saunas, and toilets where a large amount of water is expected to be used inside the space. Therefore, the shower room S can also be appropriately renamed as a bathroom, a sauna, a toilet, etc.

[0032] In addition, the indoor environment control system 500 described in the present disclosure is particularly effective in tropical to subtropical regions where the climate is hot and humid for most of the year.

[0033] Here, also with reference to Figure 2 the detailed structure of the indoor environment control system 500 will be described. Figure 2 FIG. is a block diagram showing the functional structure of the indoor environment control system in the embodiment. As Figure 1 and Figure 2As shown, the indoor environment control system 500 includes a first indoor environment information acquisition unit 21, a second indoor environment information acquisition unit 22, an outdoor environment information acquisition unit 23, a moisture emission amount estimation unit 16, an absolute moisture amount estimation unit 17, an operation control unit 10, an air conditioner 15, a ventilation device 14, and an air circulation unit 11.

[0034] The indoor environment control system 500 is divided into a sensing part for sensing, an information processing part for information processing, and a hardware part other than the sensing part. The sensing part includes the first indoor environment information acquisition unit 21, the second indoor environment information acquisition unit 22, and the outdoor environment information acquisition unit 23, and each is implemented by a sensor having one or more required sensing functions. In addition, the information processing part includes the moisture emission amount estimation unit 16, the absolute moisture amount estimation unit 17, and the operation control unit 10, and each is implemented by a computer, which includes a processor and a memory that are separate or integrated, and a program executed using these resources. As the computer constituting the information processing part, a cloud computer constructed on a network or an edge computer provided in the building where the indoor environment control system 500 is applied is used. The hardware part includes the air conditioner 15, the ventilation device 14, and the air circulation unit 11.

[0035] The first indoor environment information acquisition unit 21 is a sensor capable of measuring temperature and humidity. The first indoor environment information acquisition unit 21 measures the temperature and humidity of the shower room S respectively and outputs the temperature and humidity as first environment information to the information processing part. In addition, the first indoor environment information acquisition unit 21 can also obtain the absolute moisture amount of the shower room S by estimating based on the measured values of temperature and humidity. Therefore, the first indoor environment information acquisition unit 21 can also undertake a part of the function of the absolute moisture amount estimation unit 17. In addition, the connection between the first indoor environment information acquisition unit 21 and the information processing part is established through wired or wireless communication.

[0036] The second indoor environment information acquisition unit 22 is a sensor capable of measuring temperature and humidity. The second indoor environment information acquisition unit 22 measures the temperature and humidity of the space R respectively and outputs the temperature and humidity as second environment information to the information processing part. In addition, the second indoor environment information acquisition unit 22 can also obtain the absolute moisture amount of the space R by estimating based on the measured values of temperature and humidity. Therefore, the second indoor environment information acquisition unit 22 can also undertake a part of the function of the absolute moisture amount estimation unit 17. In addition, the connection between the second indoor environment information acquisition unit 22 and the information processing part is established through wired or wireless communication.

[0037] The outdoor environment information acquisition unit 23 is a sensor capable of measuring temperature and humidity. The outdoor environment information acquisition unit 23 measures the outdoor temperature and humidity respectively and outputs the temperature and humidity as outdoor environment information to the information processing section. In addition, the outdoor environment information acquisition unit 23 can also obtain the absolute moisture content outdoors by estimating based on the measured values of temperature and humidity. Therefore, the outdoor environment information acquisition unit 23 can also undertake a part of the function of the absolute moisture content estimation unit 17. In addition, the connection between the outdoor environment information acquisition unit 23 and the information processing section is established through wired or wireless communication.

[0038] The moisture dissipation amount estimation unit 16 estimates the moisture dissipation amount in the shower room S and the space R based on the historical records of the temperature and humidity changes of the first environment information and the second environment information. The moisture dissipation amount refers to the change amount of the absolute moisture content in the time region. That is to say, the moisture dissipation amount is the difference between the absolute moisture content at the second time point and the absolute moisture content at the first time point.

[0039] The absolute moisture content estimation unit 17 is a processing unit that estimates the absolute moisture content in the shower room S, the space R, and outdoors based on the first environment information, the second environment information, and the outdoor environment information.

[0040] The operation control unit 10 is an example of an operation control unit. Based on the first environment information, the second environment information, the outdoor environment information, the estimated moisture dissipation amount, and the estimated absolute moisture content, it conducts the operation control of the hardware part. The connections respectively made by the operation control unit 10 with the air conditioner 15, the ventilation device 14, and the air circulation unit 11 are established through wired or wireless communication. The operation control unit 10 generates a control signal and sends the control signal to each hardware part through communication to control the operation states of the respective hardware parts. The operation control unit 10 generates a control signal based on the first environment information, the second environment information, the outdoor environment information, the estimated moisture dissipation amount, and the estimated absolute moisture content through algorithm processing, but it can also generate a control signal based on the first environment information, the second environment information, the outdoor environment information, the estimated moisture dissipation amount, and the estimated absolute moisture content through the inference conducted by applying machine learning. For example, Figure 3 is a block diagram showing the functional structure of the operation control unit in another example of the embodiment. Figure 3The operation control unit 10a shown, for example, has a model 10b composed of a neural network model or the like. The model 10b is pre-generated by machine learning, which uses a large set of first environmental information, second environmental information (environmental information data D1), and correct answer data D2 (that is, a large set of data sets), and the correct answer data D2 indicates whether it is necessary to perform the operation control of the air circulation unit 11 to reduce the temperature difference between the shower room S and the space R. Thus, when the acquired first environmental information and second environmental information are input into the model 10b, a result indicating whether it is necessary to perform the operation control of the air circulation unit 11 is obtained as the output. The operation control unit 10a can also estimate and calculate whether operation control is necessary by using such a model 10b. In addition, the model 10b can be configured to generate control information for the ventilation device 14 and the air conditioner device 15 by taking other outdoor environmental information, estimated moisture emission amount, and estimated absolute moisture amount as inputs.

[0041] Return to Figure 1 and Figure 2 The air conditioner device 15 is a device that can supply (hollow arrow) an air flow in which at least one of the temperature and humidity is adjusted to the space R. The air conditioner device 15 can generate an air flow with a temperature lower than the outside air through refrigeration operation, or generate an air flow with a temperature higher than the outside air through heating operation, or generate an air flow with a humidity lower than the outside air through dehumidification operation.

[0042] The ventilation device 14 is a device that makes the shower room S negative pressure by generating an air flow flowing from the shower room S to the outdoors, and thus sucks the gas outside (outdoors or space R) from the house fittings (doors, windows, etc.) of the shower room S to exchange the air inside and outside the shower room S.

[0043] The air circulation unit 11 is a device that includes a blower fan 13 and a ventilation opening 12 and enables air to flow between the space R and the shower room S. Among them, the blower fan 13 blows air from the space R into the shower room S, the ventilation opening 12 can be controlled in its opening and closing state, and the ventilation opening 12 connects the space R and the shower room S in the open state. The blower fan 13 of the air circulation unit 11 is arranged on the vertically lower side. Thus, it is possible to effectively blow air on the moisture that easily sinks to the vertically lower side. In addition, the arrangement of the blower fan 13 and the ventilation opening 12 of the air circulation unit 11 is not limited to this. In addition, the blower fan 13 can also blow air from the shower room S into the space R.

[0044] In addition, the ventilation opening 12 opens and closes according to the operation of the air supply fan 13. For example, when the air supply fan 13 is operating, the ventilation opening 12 is in an open state, and when the air supply fan 13 is not operating, the ventilation opening 12 is in a closed state.

[0045] Next, with reference to Figures 4 to 7 simultaneously, the operation of the indoor environment control system 500 will be described. Figures 4 to 7 It is a flowchart for explaining the operation example of the indoor environment control system in the embodiment.

[0046] First, as Figure 4 shown, the first indoor environment information acquisition unit 21 acquires the first environment information (S101). The acquisition of the environment information is continuously performed within the time region. Therefore, step S101 can also be renamed as starting to acquire the first environment information. Next, the second indoor environment information acquisition unit 22 acquires the second environment information (S102). Similar to step S101, step S102 can also be renamed as starting to acquire the second environment information. Next, the outdoor environment information acquisition unit 23 acquires the outdoor environment information (S103). Similar to step S101, step S103 can also be renamed as starting to acquire the outdoor environment information.

[0047] Next, as Figure 5 shown, based on the first environment information and the second environment information, the temperature difference between the shower room S and the space R is calculated, and it is determined whether the temperature difference is greater than the threshold value a (S201). When the temperature difference is greater than the threshold value a, the shower room S and the space R are separated by a wall and have significantly different temperatures, so moisture in the air easily penetrates into the wall interior. Therefore, in the present embodiment, the operation of the air circulation unit 11 is controlled to reduce the temperature difference.

[0048] Specifically, when the temperature difference is greater than the threshold value a (Yes in S201), the operation control unit 10 operates the air circulation unit 11 and causes the air conditioner 15 to perform a refrigeration operation or a dehumidification operation to remove the latent heat of the space R (S202). Then, it returns to step S201, and the same process is repeated. In addition, since the threshold value a also varies according to the efficiency of each device and the volumes of the shower room S and the space R, the threshold value a can be determined through experiments or experience. Additionally, if 0 is applied as the threshold value a, until the temperature difference becomes 0 within the measurable range, in other words, to make the temperature difference 0, the operation control unit 10 controls the operation of the air circulation unit 11.

[0049] On the other hand, when the temperature difference is below the threshold a (No in S201), the operation control unit 10 determines whether the air circulation unit 11 is in operation (S203). If the air circulation unit 11 is in operation (Yes in S203), the operation control unit 10 stops the operation of the air circulation unit 11 and the air conditioner 15, and ends the process (S204). On the other hand, if the air circulation unit 11 is not in operation (No in S203), the operation control unit 10 ends the process without doing anything.

[0050] In a manner that is carried out in parallel with Figure 5 the process shown Figure 6 and the process shown Figure 7 are executed in parallel while being carried out simultaneously with the process shown. In Figure 6 , first, the moisture dissipation amount estimation unit 16 estimates the moisture dissipation amount (S301). When the moisture dissipation amount is large, the dew condensation amount generated due to the temperature difference between the shower room S and the space R increases, so latent heat removal corresponding to the moisture dissipation amount is performed in advance.

[0051] Specifically, when the total moisture dissipation amount of the shower room S and the space R is greater than the threshold b (Yes in S302), the operation control unit 10 causes the air conditioner 15 to perform a cooling operation or a dehumidifying operation (S303). Then, it returns to step S301 and repeats the same process. In addition, since the threshold b also varies according to the efficiency of each device and the volumes of the shower room S and the space R, the threshold b can be determined through experiments or experience. On the other hand, when the total moisture dissipation amount of the shower room S and the space R is below the threshold b (No in S302), the operation control unit 10 determines whether the air conditioner 15 is in operation (S304). If the air conditioner 15 is in operation (Yes in S304), the operation control unit 10 stops the operation of the air conditioner 15 (S305). Then, it returns to step S301 and repeats the same process. On the other hand, if the air conditioner 15 is not in operation (No in S304), the operation control unit 10 returns to step S301 without doing anything and repeats the same process.

[0052] In Figure 7In this case, first, the absolute moisture content estimation unit 17 estimates the absolute moisture content A2 of the space R (S401). In addition, the absolute moisture content estimation unit 17 estimates the outdoor absolute moisture content A0 outdoors (S402). When the absolute moisture content A2 is greater than the outdoor absolute moisture content A0, the ventilation device 14 is operated to discharge the air with a large absolute moisture content outdoors through ventilation, thereby effectively suppressing condensation. However, when the indoor environment control system 500 is used in a high-temperature and high-humidity environment as described above, the outdoor absolute moisture content is often greater. Just simply operating the ventilation device 14, for example, the energy loss such as refrigeration by the air conditioner device 15 is large, which is not preferable from the economic and environmental viewpoints. Therefore, in the present embodiment, the ventilation device 14 is not operated unless the condition that the absolute moisture content A2 is greater than the outdoor absolute moisture content A0 is satisfied, thereby improving the operation efficiency of the air conditioner device 15.

[0053] Specifically, when the absolute moisture content A2 is greater than the outdoor absolute moisture content A0 (Yes in S403), the operation control unit 10 operates the ventilation device 14 (S404). Then, it returns to step S401 and repeats the same process. On the other hand, when the absolute moisture content A2 is less than or equal to the outdoor absolute moisture content A0 (No in S403), the operation control unit 10 determines whether the ventilation device 14 is in operation (S405). If the ventilation device 14 is in operation (Yes in S405), the operation control unit 10 stops the operation of the ventilation device 14 and ends the process (S406). On the other hand, if the ventilation device 14 is not in operation (No in S405), the operation control unit 10 ends the process without doing anything.

[0054] (Effects, etc.)

[0055] The indoor environment control system 500 according to the first aspect of the present disclosure is an indoor environment control system 500 of a building. The building has a shower room S and a space R adjacent to the shower room S. The indoor environment control system 500 includes: a first indoor environment information acquisition unit 21 that acquires first environment information of the shower room S including at least temperature information and humidity information; a second indoor environment information acquisition unit 22 that acquires second environment information of the space R including at least temperature information and humidity information; an air circulation unit 11 that allows air to circulate between the shower room S and the space R; and an operation control unit (operation control unit 10) that performs operation control of the air circulation unit 11. The operation control unit performs operation control of the air circulation unit 11 so as to reduce the temperature difference between the shower room S and the space R.

[0056] Accordingly, the air circulation unit 11 is operationally controlled such that the temperature difference between the shower room S and the space R adjacent to the shower room S, which is calculated based on the acquired first environmental information and second environmental information, is not likely to become a large temperature difference suitable for the growth of bacteria such as mold. As a result, the temperature difference between the shower room S and the space R can be appropriately maintained, and the growth of bacteria such as mold can be appropriately suppressed.

[0057] In addition, regarding the indoor environment control system 500 according to the second mode, based on the indoor environment control system 500 described in the first mode, the air circulation unit 11 includes a supply fan 13 and a ventilation opening 12. Among them, the supply fan 13 blows air from the space R into the shower room S, the ventilation opening 12 can be controlled in its opening and closing state, and the ventilation opening 12 connects the space R and the shower room S in the open state.

[0058] Accordingly, by controlling the air circulation unit 11 realized by the supply fan 13 and the ventilation opening 12, the growth of bacteria such as mold can be appropriately suppressed. For the control of the air circulation unit 11, it is only necessary to blow air by the supply fan 13. In particular, since the supply fan 13 is structured to blow air into the shower room S, an air flow with a relatively large flow rate can be formed on the side of the shower room S where high humidity is likely to occur and where air is likely to stagnate, thereby effectively reducing the temperature difference.

[0059] In addition, regarding the indoor environment control system 500 according to the third mode, based on the indoor environment control system 500 described in the first or second mode, an air conditioning device 15 is further provided. The air conditioning device 15 performs cooling, heating, or dehumidification of the space R. When the operation control unit operates the air circulation unit 11, it also performs latent heat removal by causing the air conditioning device 15 to perform a cooling operation or a dehumidification operation.

[0060] Accordingly, the air supplied from the space R side through the operation of the air circulation unit 11 can be made into air from which latent heat has been removed by the cooling operation or the dehumidification operation of the air conditioning device 15. As a result, the temperature difference can be reduced more effectively. In addition, the latent heat of the relatively high-humidity air supplied from the shower room S side to the space R can also be removed. By only operating the air conditioning device 15 in the space R, further improvement in efficiency can be expected in reducing the temperature difference.

[0061] In addition, regarding the indoor environment control system 500 related to the fourth mode, the indoor environment control system 500 according to the first or second mode further includes an air conditioner 15 and a moisture emission amount estimation unit 16. Among them, the air conditioner 15 performs cooling, heating, or dehumidification of the space R, and the moisture emission amount estimation unit 16 estimates the moisture emission amounts in the shower room S and the space R based on the historical records of the temperature and humidity changes of the first environmental information and the second environmental information. The operation control unit also pre-activates the air conditioner 15 to perform cooling operation or dehumidification operation based on the moisture emission amounts estimated by the moisture emission amount estimation unit 16, so as to remove the latent heat equivalent to the moisture emission amounts.

[0062] Thereby, it is possible to remove the latent heat for offsetting the moisture emission amounts through the cooling operation or dehumidification operation of the air conditioner 15 with the required operation amount according to the estimated moisture emission amounts. Therefore, it is possible to more effectively reduce the temperature difference.

[0063] In addition, regarding the indoor environment control system 500 related to the fifth mode, the indoor environment control system 500 according to any one of the first to fourth modes further includes a ventilation device 14, an outdoor environment information acquisition unit 23, and an absolute moisture amount estimation unit 17. Among them, the ventilation device 14 ventilates at least the air in the shower room S, the outdoor environment information acquisition unit 23 acquires outdoor environmental information including at least moisture amount information, the second environmental information further includes moisture amount information, and the absolute moisture amount estimation unit 17 estimates the absolute moisture amounts of the space R and the outdoors respectively based on the second environmental information and the outdoor environmental information. When the absolute moisture amount of the space R estimated by the absolute moisture amount estimation unit 17 is larger than that of the outdoors, the operation control unit also activates the ventilation device 14.

[0064] Thereby, it is possible to activate the ventilation device 14 only when it is effective after estimating whether ventilation is effective compared to exchanging the air in the shower room S with the space R according to the difference in absolute moisture amounts. Especially in the tropical to subtropical regions where the climate is hot and humid for most of the year, the absolute moisture amount of the outdoors is often larger than that of the space R, and there are also cases where high-humidity air cannot be discharged only by randomly activating the ventilation device 14. From this situation, it can be said that it is important to estimate whether ventilation is effective based on the difference in absolute moisture amounts.

[0065] In addition, the indoor environment control system 500 related to the sixth mode is an indoor environment control system 500 of a building. Among them, the building has a shower room S and a space R adjacent to the shower room S. The indoor environment control system 500 includes: one or more processors; and an air circulation unit 11 that circulates air between the shower room S and the space R. Among them, the one or more processors perform the following processes: obtaining first environmental information of the shower room S including at least temperature information and humidity information; obtaining second environmental information of the space R including at least temperature information and humidity information; inputting the obtained first environmental information and second environmental information into the model 10b, and causing the model 10b to output whether the air circulation unit 11 needs to operate. Among them, the model 10b is generated using a large amount of first environmental information, second environmental information, and correct answer data D2. The correct answer data D2 indicates whether operation control of the air circulation unit 11 for reducing the temperature difference between the shower room S and the space R is required; and when the operation of the air circulation unit 11 is required, causing the air circulation unit 11 to operate.

[0066] Thus, it is possible to determine whether the air circulation unit 11 needs to operate through one or more processors. The one or more processors can input the obtained first environmental information and second environmental information into the pre-generated and learned model 10b, and output through estimation whether the air circulation unit 11 needs to operate. Moreover, the air circulation unit 11 can be caused to operate when the output result regarding whether the air circulation unit 11 needs to operate is required.

[0067] In addition, regarding the indoor environment control system 500 related to the seventh mode, according to the indoor environment control system 500 described in the sixth mode, the model 10b is a neural network model.

[0068] Thus, the model 10b can be implemented through a neural network model.

[0069] In addition, the indoor environment control method related to the eighth mode is an indoor environment control method of a building executed by a computer. Among them, the building has a shower room S and a space R adjacent to the shower room S. The indoor environment control method includes the following steps: obtaining first environmental information of the shower room S including at least temperature information and humidity information; obtaining second environmental information of the space R including at least temperature information and humidity information; and performing operation control on the air circulation unit 11 to reduce the temperature difference between the shower room S and the space R. Among them, the air circulation unit 11 circulates air between the shower room S and the space R.

[0070] Thus, the same effect as that of the indoor environment control system 500 described in the first mode can be achieved.

[0071] In addition, the indoor environment control method according to the ninth mode is an indoor environment control method for a building executed by a computer. The building has a shower room S and a space R adjacent to the shower room S. The indoor environment control method includes the following steps: obtaining first environment information of the shower room S including at least temperature information and humidity information; obtaining second environment information of the space R including at least temperature information and humidity information; inputting the obtained first environment information and second environment information into a model 10b, so that the model 10b outputs whether the air circulation unit 11 needs to operate. The model 10b is generated using a large amount of first environment information, second environment information, and correct answer data D2. The correct answer data D2 indicates whether operation control of the air circulation unit 11 for reducing the temperature difference between the shower room S and the space R is required. The air circulation unit 11 allows air to flow between the shower room S and the space R; and when the air circulation unit 11 needs to operate, making the air circulation unit 11 operate.
