In addition, the present invention is not limited to the embodiment described below. Furthermore, in the description of the accompanying drawings, the same symbols are marked on the same parts.

[0019] Schematic structure of indoor environment control system

[0020] Figure 1 It is a block diagram showing the structure of the indoor environment control system 1 according to the embodiment.

[0021] The indoor environment control system 1 is a HEMS (Home Energy Management System) installed in a residence or a BEMS (Building Energy Management System) installed in a building other than a residence, and is used to perform environmental control for each room in the residence or building.

[0022] The indoor environment control system 1 includes a solar power generation glass 2, a measuring device 3, an electric blind 4, an air conditioning device 5, a lighting device 6, and a control device 7. Figure 1 In the figure, for the sake of convenience, the solar power generation glass 2, the measuring device 3, the electric blinds 4, the air conditioning device 5 and the lighting device 6 set in one room (hereinafter referred to as the target room) are shown. In the case where there are multiple target rooms, multiple solar power generation glasses 2, measuring devices 3, electric blinds 4, air conditioning devices 5 and lighting devices 6 are respectively provided corresponding to the target rooms. In addition, in the case where the target room is a large room, multiple solar power generation glasses 2, measuring devices 3, electric blinds 4, air conditioning devices 5 and lighting devices 6 may also be provided. That is, the electric blinds 4, air conditioning devices 5 and lighting devices 6 that are the control objects of the control device 7 can be multiple.

[0023] The solar power generation glass 2, the measuring device 3, the electric blinds 4, the air conditioning device 5, and the lighting device 6 are connected to the control device 7 in a communicative manner. In addition, the communication may be wired communication or wireless communication.

[0024] The solar power generation glass 2 is equivalent to the solar power generation element of the present invention. The solar power generation glass 2 is provided in the opening between the target room and the outside of the target room, is used to separate the target room from the outside, and absorbs part of the sunlight incident into the target room through the opening to generate electricity. More specifically, the solar power generation glass 2 transmits visible light and absorbs infrared and ultraviolet rays, which are invisible light, to generate electricity.

[0025] When there are a plurality of solar power generation glasses 2 in the target room, a representative one of the plurality of solar power generation glasses 2 may be used as the indoor environment control system 1 .

[0026] Furthermore, the solar power generation glass 2 includes a room temperature detection sensor 21 and an outside air temperature detection sensor 22 .

[0027] The room temperature detection sensor 21 is composed of, for example, a thermistor, and detects the temperature in the target room. The room temperature detection sensor 21 outputs a signal corresponding to the detected temperature in the target room to the control device 7 .

[0028] The outside temperature detection sensor 22 is composed of, for example, a thermistor, and detects the outside temperature outside the target room. The outside temperature detection sensor 22 outputs a signal corresponding to the detected outside temperature outside the target room to the control device 7 .

[0029] Furthermore, at least one of the room temperature detection sensor 21 , the outside temperature detection sensor 22 , and the processor 74 constituting the control device 7 is driven by the power generated by the solar power generation glass 2 .

[0030] The measuring device 3 is a device for measuring the power generated by the solar power generation glass 2, for example, detecting the current and voltage, and after digital signal processing through an A / D (Analog / Digital) converter, if it is AC, the effective power (effective value) is measured in each cycle. Then, the measuring device 3 outputs a signal corresponding to the measured effective power as the power generation of the solar power generation glass 2 to the control device 7.

[0031] The electric blind 4 is equivalent to the sunshade device of the present invention. The electric blind 4 changes the position under the control of the control device 7 to change the amount of solar radiation incident on the target room. More specifically, the electric blind 4 is arranged inside the target room relative to the solar power generation glass 2, and changes the amount of solar radiation incident on the target room by changing the blind angle (position of the present invention) under the control of the control device 7.

[0032] In addition, the sunshade device of the present invention is not limited to the above-mentioned electric blinds 4 as long as it is a device that can change the amount of solar radiation entering the target room by changing its position. It can also use electric awnings and electric roller blinds arranged outside the target room, or electric curtains arranged in the target room.

[0033] The air conditioner 5 is configured to include an indoor unit and an outdoor unit connected via a refrigerant pipe. The indoor unit is arranged in the target room. On the other hand, the outdoor unit is arranged outside the target room. Furthermore, the air conditioner 5, under the control of the control device 7, blows air of a suitable temperature into the target room by exchanging heat between the refrigerant and the outside air, thereby performing air conditioning in the target room.

[0034] The lighting device 6 is configured to include a light emitting element such as an LED (Light Emitting Diode) that emits lighting light, and is disposed on the ceiling of the target room, etc. Furthermore, the lighting device 6 irradiates the lighting light into the target room under the control of the control device 7, and adjusts the brightness (the amount of the irradiated lighting light) in the target room according to the supplied power.

[0035] The control device 7 is equivalent to the indoor environment control device of the present invention. The control device 7 performs centralized and unified control of the operation of the electric blind 4, the air conditioning device 5 and the lighting device 6 based on the power generation of the solar power generation glass 2 output from the measuring device 3. The control device 7 includes an input unit 71, a display unit 72, a storage unit 73 and a processor 74.

[0036] The input unit 71 is equivalent to the operation receiving unit of the present invention. The input unit 71 is composed of operating devices such as a mouse, a keyboard, and a touch panel, and is used to receive user operations. Then, the input unit 71 outputs an operation signal corresponding to the user operation to the processor 74.

[0037] The display unit 72 is composed of a display using liquid crystal or organic EL (Electro Luminescence) or the like, and displays a predetermined image under the control of the processor 74 .

[0038] The storage unit 73 stores programs (including the indoor environment control program of the present invention) executed by the processor 74 and information necessary for processing by the processor 74 .

[0039] The processor 74 is implemented by executing various programs stored in the storage unit 73 by a controller such as a CPU (Central Processing Unit) and an MPU (MicroProcessing Unit). In addition, the processor 74 controls the operation of the control device 7 as a whole while controlling the operation of the electric blinds 4, the air conditioning device 5 and the lighting device 6. In addition, the processor 74 is not limited to a CPU and an MPU, and may also be composed of an integrated circuit such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field-Programmable Gate Array).

[0040] In addition, the function of the processor 74 will be described in the "indoor environment control method" described later.

[0041] Indoor environment control methods

[0042] In the present embodiment, the processor 74 performs control corresponding to a mode set by a user operation on the input unit 71 among a plurality of modes. The plurality of modes are the first to third modes. The first to third modes are modes for performing different controls on the operation of the electric blind 4, the air conditioner 5, and the lighting device 6 based on the power generation of the solar power generation glass 2. Hereinafter, the indoor environment control method in the first mode, the indoor environment control method in the second mode, and the indoor environment control method in the third mode will be described in order.

[0043] Indoor environment control method in the first mode

[0044] First, the indoor environment control method in the first mode is described.

[0045] Figure 2 is a flowchart showing the indoor environment control method in the first mode.

[0046] First, the processor 74 obtains the power generation of the solar power generation glass 2 from the measuring device 3 (step S1A). In addition, the processor 74 obtains the outside air temperature from the outside air temperature detection sensor 22 (step S1B), and obtains the temperature (room temperature) in the target room from the room temperature detection sensor 21 (step S1C).

[0047] After step S1C, the processor 74 calculates the window solar radiation based on the power generation obtained in step S1A and the first correlation information stored in the storage unit 73 (step S1D). The first correlation information is information indicating the correlation between the power generation and the window solar radiation. That is, in step S1D, the processor 74 refers to the first correlation information to determine the window solar radiation corresponding to the power generation obtained in step S1A.

[0048] After step S1D, the processor 74 calculates the current weather condition (direct / scattered ratio) based on the window solar radiation calculated in step S1D and the second correlation information stored in the storage unit 73 (step S1E). The second correlation information is information indicating the correlation between the window solar radiation and the weather condition (direct / scattered ratio) set for each date and time. That is, in step S1E, the processor 74 refers to the second correlation information to determine the weather condition (direct / scattered ratio) corresponding to the current date and time and corresponding to the window solar radiation calculated in step S1D.

[0049] After step S1E, the processor 74 calculates the amount of heat intrusion into the target room based on the outside air temperature obtained in step S1B, the room temperature obtained in step S1C, the window surface solar radiation calculated in step S1D, the cloudy / sunny state (direct / scattered ratio) calculated in step S1E, and the window constituent material characteristic information stored in the storage unit 73 (step S1F). The window constituent material characteristic information is information indicating the characteristics of the constituent material of the solar power generation glass 2.

[0050] After step S1F, the processor 74 calculates the ratio of solar radiation to illuminance (luminous efficiency) based on the cloudy / clear state (direct radiation / diffuse radiation ratio) calculated in step S1E (step S1G).

[0051] After step S1G, the processor 74 calculates the desktop illumination in the target room based on the sunny and cloudy conditions (direct / diffuse ratio) calculated by step S1E, the ratio of solar radiation to illumination (luminous efficiency) calculated by step S1G, and the window material characteristic information stored in the storage unit 73 (step S1H).

[0052] After step S1H, the processor 74 compares the heat intrusion amount calculated in step S1F with a threshold value stored in the storage unit 73 to determine whether the heat intrusion amount exceeds the threshold value (step S1I).

[0053] When it is determined that the heat intrusion amount does not exceed the threshold value (step S1I: NO), the processor 74 proceeds to step S10.

[0054] On the other hand, when it is determined that the heat intrusion amount exceeds the threshold value (step S1I: Yes), the processor 74 determines whether the current shutter angle of the electric shutter 4 is less than the maximum angle (step S1J). The maximum angle refers to the angle at which the shutter angle cannot be further increased (reducing the amount of solar radiation incident on the target room) in design.

[0055] When it is determined that the current blind angle is the maximum angle (step S1J: NO), the processor 74 proceeds to step S10.

[0056] On the other hand, when it is determined that the current shutter angle is less than the maximum angle (step S1J: Yes), the processor 74 calculates a shutter angle for reducing the portion of the heat intrusion amount exceeding the threshold value (step S1K). Then, the processor 74 controls the operation of the electric shutter 4 so as to set the shutter angle of the electric shutter 4 to the shutter angle calculated in step S1K (step S1L: control step).

[0057] After step S1L, the processor 74 recalculates the amount of heat intrusion into the target room based on the blind angle calculated by step S1K, the outside air temperature obtained by step S1B, the room temperature obtained by step S1C, the window surface solar radiation calculated by step S1D, the cloudy / sunny conditions (direct / scattered ratio) calculated by step S1E, and the window material characteristic information stored in the storage unit 73 (step S1M).

[0058] After step S1M, the processor 74 recalculates the desktop illumination in the target room based on the blind angle calculated by step S1K, the cloudy / sunny conditions (direct / scattered ratio) calculated by step S1E, the ratio of solar radiation to illumination (luminous efficiency) calculated by step S1G, and the window material characteristic information stored in the storage unit 73 (step S1N).

[0059] After step S1N, the processor 74 controls the operation of the air conditioner 5 based on the heat intrusion amount calculated in step S1F or the heat intrusion amount recalculated in step S1M (step S10: control step).

[0060] After step S10, processor 74 controls the operation of lighting device 6 based on the desktop illuminance calculated in step S1H or the desktop illuminance recalculated in step S1N (step S1P: control step).

[0061] Furthermore, in the indoor environment control method in the first mode, the processor 74 repeatedly executes the processing of the above-mentioned steps S1A to S1P.

[0062] Indoor environment control method in the second mode

[0063] Next, the indoor environment control method in the second mode is described.

[0064] Figure 3 is a flowchart showing the indoor environment control method in the second mode.

[0065] First, the processor 74 sequentially executes the processes of steps S2A to S2G. The processes of steps S2A to S2G are respectively the same as the processes of steps S1A to S1G described above.

[0066] After step S2G, the processor 74 calculates the window surface illuminance and the desktop illuminance of the target room respectively based on the sunny / cloudy conditions (direct / scattered ratio) calculated by step S2E, the ratio of solar radiation to illuminance (luminous efficiency) calculated by step S2G, and the window material characteristic information stored in the storage unit 73 (steps S2H and S2I).

[0067] After step S2I, processor 74 calculates the window surface brightness / glare value (glare degree) in the target room based on the window surface illuminance calculated in step S2H ​​(step S2J).

[0068] After step S2J, the processor 74 compares the window surface brightness / glare value (glare degree) calculated by step S2J with the threshold value stored in the storage unit 73 to determine whether the window surface brightness / glare value (glare degree) exceeds the threshold value (step S2K).

[0069] When it is determined that the window surface brightness / glare value (glare degree) does not exceed the threshold value (step S2K: No), the processor 74 proceeds to step S2N.

[0070] On the other hand, when it is determined that the window surface brightness / glare value (blinding degree) exceeds the threshold value (step S2K: Yes), the processor 74 determines whether the current blind angle of the electric blind 4 is less than the maximum angle (step S2L) as in step S1J.

[0071] When it is determined that the current blind angle is the maximum angle (step S2L: NO), the processor 74 proceeds to step S2S.

[0072] On the other hand, when it is determined that the current blind angle is less than the maximum angle (step S2L: Yes), the processor 74 calculates a first blind angle for reducing the portion of the window surface brightness / glare value (glare degree) exceeding the threshold value (step S2M). The first blind angle is equivalent to the first position of the present invention.

[0073] After step S2M, the processor 74 compares the desktop illumination calculated in step S2I with a threshold value stored in the storage unit 73 to determine whether the desktop illumination is less than the threshold value (step S2N).

[0074] When it is determined that the desk illuminance is equal to or greater than the threshold value (step S2N: No), the processor 74 proceeds to step S2S.

[0075] On the other hand, if it is determined that the desktop illuminance is less than the threshold (step S2N: Yes), the processor 74 calculates a second blind angle for compensating for the lack of desktop illuminance compared to the threshold (step S2O). The second blind angle corresponds to the second position of the present invention.

[0076] After step S2O, the processor 74 controls the operation of the electric blind 4 to set the blind angle of the electric blind 4 to the larger blind angle of the first blind angle calculated by step S2M and the second blind angle calculated by step S2O (step S2P: control step).

[0077] After step S2P, the processor 74 recalculates the desktop illumination in the target room (step S2Q) based on the larger blind angle, the first blind angle calculated by step S2M and the second blind angle calculated by step S2O, the cloudy or sunny conditions (direct / diffuse ratio) calculated by step S2E, the ratio of solar radiation to illumination (luminous efficiency) calculated by step S2G, and the window material characteristic information stored in the storage unit 73.

[0078] After step S2Q, the processor 74 recalculates the amount of heat intrusion into the target room (step S2R) based on the larger blind angle of the first blind angle calculated by step S2M and the second blind angle calculated by step S2O, the outside air temperature obtained by step S2B, the room temperature obtained by step S2C, the window surface solar radiation calculated by step S2D, the cloudy / clear conditions (direct / scattered ratio) calculated by step S2E, and the window material characteristic information stored in the storage unit 73.

[0079] After step S2R, processor 74 controls the operation of lighting device 6 based on the desktop illuminance calculated in step S2I or the desktop illuminance recalculated in step S2Q (step S2S: control step).

[0080] After step S2S, the processor 74 controls the operation of the air conditioner 5 based on the heat intrusion amount calculated in step S2F or the heat intrusion amount recalculated in step S2R (step S2T: control step).

[0081] Furthermore, in the indoor environment control method in the second mode, the processor 74 repeatedly executes the processing of the above-mentioned steps S2A to S2T.

[0082] Indoor environment control method in the third mode

[0083] Next, the indoor environment control method in the third mode is described.

[0084] Figure 4 is a flowchart showing the indoor environment control method in the third mode.

[0085] First, the processor 74 sequentially executes the processes of steps S3A to S3I. The processes of steps S3A to S3I are the same as the processes of steps S2A to S2H and S2J described above, respectively.

[0086] After step S3I, as in step S2K, the processor 74 compares the window surface brightness / glare value (glare degree) calculated by step S3I with the threshold value stored in the storage unit 73 to determine whether the window surface brightness / glare value (glare degree) exceeds the threshold value (step S3J).

[0087] When it is determined that the window surface brightness / glare value (glare degree) does not exceed the threshold value (step S3J: No), the processor 74 returns to step S3A.

[0088] On the other hand, when it is determined that the window surface brightness / glare value (glare degree) exceeds the threshold (step S3J: yes), the processor 74 determines whether the current blind angle of the electric blind 4 is less than the maximum angle (step S3K), as in steps S1J and S2L.

[0089] When it is determined that the current blind angle is the maximum angle (step S3K: NO), the processor 74 returns to step S3A.

[0090] On the other hand, when it is determined that the current blind angle is less than the maximum angle (step S3K: Yes), the processor 74 calculates a first blind angle for reducing the portion of the window surface brightness / glare value (glare degree) exceeding the threshold value (step S3L), similar to step S2M. The first blind angle is equivalent to the first position of the present invention.

[0091] After step S3L, similarly to step S1I, the processor 74 compares the heat intrusion amount calculated in step S3F with the threshold value stored in the storage unit 73 to determine whether the heat intrusion amount exceeds the threshold value (step S3M).

[0092] When it is determined that the heat intrusion amount does not exceed the threshold value (step S3M: NO), the processor 74 returns to step S3A.

[0093] On the other hand, when it is determined that the heat intrusion amount exceeds the threshold value (step S3M: Yes), the processor 74 calculates a second louver angle for reducing the portion of the heat intrusion amount exceeding the threshold value (step S3N) as in step S1K. The second louver angle corresponds to the second position of the present invention.

[0094] After step S3N, the processor 74 controls the action of the electric blind 4 to set the blind angle of the electric blind 4 to the larger blind angle between the first blind angle calculated by step S3L and the second blind angle calculated by step S3N (step S3O: control step).

[0095] Furthermore, after step S30, the air conditioner 5 responds to the room temperature change in the target room caused by step S30 through the room temperature sensor provided in the indoor unit of the air conditioner 5, and automatically performs air conditioning in the target room without the control of the processor 74. In addition, the lighting device 6 responds to the illuminance change in the target room caused by step S30 through the illuminance sensor provided in the lighting device 6, and automatically adjusts the brightness in the target room without the control of the processor 74.

[0096] Furthermore, in the indoor environment control method in the third mode, the processor 74 repeatedly executes the processing of the above-mentioned steps S3A to S3O.

[0097] Other Implementations

[0098] As mentioned above, although the form for implementing this invention was described, it should not be understood that this invention is limited to only the said embodiment.

[0099] In the above-described embodiment, the solar power generation element of the present invention is not limited to the solar power generation glass 2 and other structures may be adopted as long as it absorbs part of the sunlight incident into the target room to generate electricity.

[0100] In the above-described embodiment, the first to third modes are employed as the plurality of modes of the present invention, but the number of modes is not limited to three, and may be two, or may be four or more.

[0101] In the above-described embodiment, each control corresponding to the first to third modes is executed, but the present invention is not limited thereto, and a control corresponding to only one of the modes may be executed.

[0102] The process described in the above embodiment is not limited to Figures 2 to 4 The order can also be changed within a reasonable range.

[0103] The present invention is an indoor environment control device for performing indoor environment control of a building, comprising: a processor, which controls the operation of at least any one of a sunshade device, an air-conditioning device and a lighting device, wherein the sunshade device changes the amount of solar radiation incident into the room by changing its position, the air-conditioning device is used to perform air conditioning in the room, and the lighting device is used to irradiate lighting light into the room and adjust the brightness of the room, and the processor controls the operation of at least any one of the sunshade device, the air-conditioning device and the lighting device based on the amount of power generated by a solar power generation element, and the solar power generation element is an element that absorbs a portion of the sunlight incident into the room to generate electricity.

[0104] In the present invention, a processor constituting an indoor environment control device controls the operation of at least one of a sunshade device, an air conditioning device, and a lighting device based on the amount of power generated by a solar power generation element (hereinafter referred to as indoor environment control), wherein the solar power generation element is an element that absorbs a portion of the sunlight incident into the room to generate power. In other words, the amount of power generated is the amount of power generated by absorbing a portion of the sunlight incident into a room that is the object of indoor environment control (hereinafter referred to as the target room), so the estimated value calculated based on the amount of power generated can be regarded as a value close to the actual measured value. The estimated value is an estimated value used for indoor environment control, and examples thereof include the amount of heat intrusion into the target room, the desktop illuminance in the target room, the window surface brightness in the target room, and the like.

[0105] Therefore, according to the indoor environment control device of the present invention, by executing indoor environment control based on the above-mentioned power generation amount, it is possible to perform optimal environment control in the target room.

[0106] Furthermore, in the present invention, in the indoor environment control device, the processor controls the operation of at least any one of the sunshade device, the air conditioning device, and the lighting device based on the window solar radiation amount calculated based on the power generation amount.
