Description

[Technical field]

[0001] The present invention relates to an indoor environment control device, an indoor environment control system, an indoor environment control method, and an indoor environment control program for controlling the indoor environment of a building. [Background technology]

[0002] 2. Description of the Related Art Conventionally, an indoor environment control system is known that controls the indoor environment of a building based on the amount of power generated by a solar power generation device (see, for example, Patent Document 1). In the indoor environment control system described in Patent Document 1, a solar power generation device is installed on the roof of a building. The indoor environment control system determines the current weather from the amount of power generated by the solar power generation device, and estimates the solar radiation heat entering the room through the openings of the building based on the weather and structural information including the positions and directions of the openings. The indoor environment control system then performs indoor environmental control based on the estimated solar radiation heat. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6742506 Summary of the Invention [Problem to be solved by the invention]

[0004] In the indoor environment control system described in Patent Document 1, the solar radiation heat entering the room through the opening is estimated using the current weather determined from the amount of power generated by a solar power generation device installed on the roof of the building and structural information including the position and direction of the opening. Therefore, the solar radiation heat is only an estimated value and it is difficult to make it close to the actual measured value. For example, when there are buildings around and a shadow is cast on the exterior wall of the target building, the position and range of the shadow changes from moment to moment, and it is thought that the individual solar radiation conditions will differ even for openings located on the same exterior wall. However, it is difficult to perform optimal environmental control for the room according to the solar radiation conditions of each opening from the amount of power generation observed at a representative position such as the roof.

[0005] The present invention has been made in consideration of the above, and aims to provide an indoor environment control device, an indoor environment control system, an indoor environment control method, and an indoor environment control program that can perform optimal environmental control within a room.

[Diagram 2] 4 is a flowchart showing a method for controlling an indoor environment in a first mode. [Diagram 3] 6 is a flowchart showing a method for controlling an indoor environment in a second mode. [Figure 4] 10 is a flowchart showing a method for controlling an indoor environment in a third mode. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a mode for carrying out the present invention (hereinafter, referred to as an embodiment) will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described below. Furthermore, in the description of the drawings, the same parts are given the same reference numerals.

[0013] [Outline of indoor environment control system] FIG. 1 is a block diagram showing a configuration of an indoor environment control system 1 according to an embodiment. The indoor environment control system 1 is a Home Energy Management System (HEMS) installed in a house or a Building Energy Management System (BEMS) installed in a building other than a house, and performs environmental control for each room in the house or building.

[0014] This indoor environment control system 1 includes a photovoltaic glass 2, a measuring device 3, an electric blind 4, an air conditioner 5, a lighting device 6, and a control device 7. For ease of explanation, FIG. 1 illustrates the photovoltaic glass 2, the measuring device 3, the electric blind 4, the air conditioner 5, and the lighting device 6 installed in one room (hereinafter referred to as a target room). When there are multiple target rooms, multiple pieces of the photovoltaic glass 2, the measuring device 3, the electric blind 4, the air conditioner 5, and the lighting device 6 are installed corresponding to the target rooms. When the target room is a large room, multiple pieces of the photovoltaic glass 2, the measuring device 3, the electric blind 4, the air conditioner 5, and the lighting device 6 may be installed. In other words, there may be multiple pieces of the electric blind 4, the air conditioner 5, and the lighting device 6 that are the targets of control by the control device 7.

[0015] Here, the photovoltaic glass 2, the measuring device 3, the electric blinds 4, the air conditioner 5, and the lighting device 6 are connected to the control device 7 so as to be able to communicate information. Note that the communication may be wired communication or wireless communication.

[0016] The photovoltaic glass 2 corresponds to a photovoltaic element according to the present invention. This photovoltaic glass 2 is provided at an opening between a target room and the outside of the target room, separating the target room from the outside, and absorbing a portion of the sunlight that enters the target room through the opening to generate electricity. More specifically, the photovoltaic glass 2 transmits visible light while absorbing invisible light such as infrared and ultraviolet light to generate electricity.

[0017] When a plurality of photovoltaic glass panels 2 are present in a target room, one representative photovoltaic glass panel 2 may be used as the indoor environment control system 1.

[0018] The photovoltaic glass 2 also includes a room temperature detection sensor 21 and an outside air temperature detection sensor 22 . The room temperature detection sensor 21 is configured with, for example, a thermistor, and detects the temperature inside the target room. The room temperature detection sensor 21 then outputs a signal to the control device 7 according to the detected temperature inside the target room. The outside air temperature detection sensor 22 is configured with, for example, a thermistor, and detects the outside air temperature outside the target room. The outside air temperature detection sensor 22 outputs a signal to the control device 7 according to the detected outside air temperature outside the target room.

[0019] At least one of the room temperature detection sensor 21, the outside air temperature detection sensor 22, and the processor 74 constituting the control device 7 is driven by the power generated by the photovoltaic glass 2.

[0020] The measuring device 3 is a device that measures the generated power output from the photovoltaic glass 2, and for example detects current and voltage, performs digital signal processing using an A / D converter, and measures the active power (effective value) for each cycle in the case of AC. The measuring device 3 then outputs a signal corresponding to the measured active power to the control device 7 as the amount of power generated by the photovoltaic glass 2.

[0021] The electric blinds 4 correspond to the solar shading device according to the present invention. The electric blinds 4 change the amount of solar radiation entering the target room by changing their position under the control of the control device 7. More specifically, the electric blinds 4 are disposed on the inside side of the target room with respect to the photovoltaic glass 2, and change the amount of solar radiation entering the target room by changing the blind angle (position according to the present invention) under the control of the control device 7.

[0022] In addition, the solar shading device according to the present invention is not limited to the above-mentioned electric blinds 4, and may also be an electric awning and electric shutters placed outside the target room, or an electric curtain placed inside the target room, as long as it is a device that can change the amount of solar radiation entering the target room by changing its position.

[0023] The air conditioner 5 includes an indoor unit and an outdoor unit connected via a refrigerant pipe. The indoor unit is disposed inside the target room. Meanwhile, the outdoor unit is disposed outside the target room. Under the control of the control device 7, the air conditioner 5 exchanges heat between the refrigerant and the outside air to blow air at an appropriate temperature into the target room, thereby conditioning the target room.

[0024] The lighting device 6 includes light-emitting elements such as LEDs (Light Emitting Diodes) that emit illumination light, and is disposed on the ceiling of the target room. Under the control of the control device 7, the lighting device 6 irradiates illumination light into the target room, and adjusts the brightness (the amount of irradiated illumination light) in the target room according to the power supplied.

[0025] The control device 7 corresponds to an indoor environment control device according to the present invention. This control device 7 comprehensively controls the operations of the electric blinds 4, the air conditioner 5, and the lighting device 6 based on the power generation amount of the solar power generating glass 2 output from the measurement device 3. This control device 7 includes an input unit 71, a display unit 72, a storage unit 73, and a processor 74.

[0026] The input unit 71 corresponds to an operation receiving unit according to the present invention. The input unit 71 is composed of operation devices such as a mouse, a keyboard, and a touch panel, and receives user operations. The input unit 71 outputs an operation signal corresponding to the user operation to the processor 74.

[0027] The display unit 72 is configured with 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.

[0028] The storage unit 73 stores programs executed by the processor 74 (including the indoor environment control program according to the present invention), information necessary for the processing of the processor 74, and the like.

[0029] The processor 74 is realized by a controller such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing various programs stored in the storage unit 73. The processor 74 controls the operation of the electric blinds 4, the air conditioner 5, and the lighting device 6, and also controls the operation of the entire control device 7. The processor 74 is not limited to a CPU or an MPU, and may be configured with an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). The function of the processor 74 will be explained in the "Indoor environment control method" described later.

[0030] [Indoor environment control method] In this embodiment, the processor 74 executes control according to a mode set by a user operation on the input unit 71 out of a plurality of modes. The plurality of modes are first to third modes. These first to third modes are modes for executing mutually different controls as controls of the operation of the electric blinds 4, the air conditioner 5, and the lighting device 6 based on the amount of power generated by the photovoltaic power generation glass 2. Below, 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.

[0031] [Indoor environment control method in first mode] First, the indoor environment control method in the first mode will be described. FIG. 2 is a flowchart showing the indoor environment control method in the first mode. First, the processor 74 acquires the amount of power generated by the photovoltaic glass 2 from the measurement device 3 (step S1A). The processor 74 also acquires the outside air temperature from the outside air temperature detection sensor 22 (step S1B) and acquires the temperature (room temperature) in the target room from the room temperature detection sensor 21 (step S1C).

[0032] After step S1C, the processor 74 calculates the amount of solar radiation on a window based on the amount of power generation acquired in step S1A and the first correlation information stored in the storage unit 73 (step S1D). Here, the first correlation information is information indicating the correlation between the amount of power generation and the amount of solar radiation on a window. That is, in step S1D, the processor 74 refers to the first correlation information and identifies the amount of solar radiation on a window corresponding to the amount of power generation acquired in step S1A.

[0033] After step S1D, the processor 74 calculates the current sunny / cloudy state (direct / diffuse ratio) based on the window solar radiation calculated in step S1D and the second correlation information stored in the memory unit 73 (step S1E). Here, the second correlation information is information indicating the correlation between the window solar radiation and the sunny / cloudy state (direct / diffuse ratio) provided for each date and time. That is, in step S1E, the processor 74 refers to the second correlation information and identifies the sunny / cloudy state (direct / diffuse ratio) that corresponds to the current date and time and the window solar radiation calculated in step S1D.

[0034] After step S1E, the processor 74 calculates the amount of heat entering the target room based on the outside air temperature acquired in step S1B, the room temperature acquired in step S1C, the amount of solar radiation on the window calculated in step S1D, the sunny / cloudy state (direct / diffuse ratio) calculated in step S1E, and the window component material characteristic information stored in the memory unit 73 (step S1F). Here, the window component material characteristic information is information indicating the characteristics of the constituent materials of the photovoltaic glass 2.

[0035] After step S1F, processor 74 calculates the ratio of solar radiation to illuminance (luminous efficiency) based on the sunny / cloudy condition (direct / diffuse ratio) calculated in step S1E (step S1G).

[0036] After step S1G, the processor 74 calculates the desk surface illuminance in the target room based on the sunny / cloudy condition (direct / diffuse ratio) calculated in step S1E, the ratio of solar radiation to illuminance (luminous efficiency) calculated in step S1G, and the window component property information stored in the memory unit 73 (step S1H).

[0037] After step S1H, the processor 74 compares the amount of entering heat calculated in step S1F with a threshold value stored in the storage unit 73, and determines whether the amount of entering heat exceeds the threshold value (step S1I).

[0038] If it is determined that the amount of entering heat does not exceed the threshold value (step S1I: No), the processor 74 proceeds to step S1O. On the other hand, if it is determined that the amount of heat penetration exceeds the threshold (step S1I: Yes), the processor 74 determines whether the current blind angle of the electric blinds 4 is less than the maximum angle (step S1J). Here, the maximum angle means an angle at which the blind angle cannot be increased any further (the amount of solar radiation into the target room cannot be reduced) due to design.

[0039] If it is determined that the current blind angle is the maximum angle (step S1J: No), the processor 74 proceeds to step S1O. On the other hand, if it is determined that the current blind angle is less than the maximum angle (step S1J: Yes), the processor 74 calculates the blind angle to reduce the amount of heat entry that exceeds the threshold (step S1K). Then, the processor 74 controls the operation of the electric blinds 4, and sets the blind angle of the electric blinds 4 to the blind angle calculated in step S1K (step S1L: control step).

[0040] After step S1L, processor 74 recalculates the amount of heat entering the target room based on the blind angle calculated in step S1K, the outside air temperature obtained in step S1B, the room temperature obtained in step S1C, the amount of solar radiation on the window calculated in step S1D, the sunny / cloudy condition (direct / diffuse ratio) calculated in step S1E, and the window component material characteristic information stored in memory unit 73 (step S1M).

[0041] After step S1M, the processor 74 recalculates the desk surface illuminance in the target room based on the blind angle calculated in step S1K, the sunny / cloudy condition (direct / diffuse ratio) calculated in step S1E, the ratio of solar radiation to illuminance (luminous efficiency) calculated in step S1G, and the window component material characteristic information stored in the memory unit 73 (step S1N).

[0042] After step S1N, the processor 74 controls the operation of the air conditioner 5 based on the amount of entering heat calculated in step S1F or the amount of entering heat newly calculated in step S1M (step S1O: control step).

[0043] After step S1O, the processor 74 controls the operation of the lighting device 6 based on the desk surface illuminance calculated in step S1H or the desk surface illuminance recalculated in step S1N (step S1P: control step).

[0044] In the indoor environment control method in the first mode, the processor 74 repeatedly executes the processes of steps S1A to S1P described above.

[0045] [Indoor environment control method in second mode] Next, the indoor environment control method in the second mode will be described. FIG. 3 is a flowchart showing the indoor environment control method in the second mode. First, processor 74 sequentially executes the processes of steps S2A to S2G. Note that the processes of steps S2A to S2G are similar to the processes of steps S1A to S1G described above, respectively.

[0046] After step S2G, the processor 74 calculates the window surface illuminance and the desk surface illuminance of the target room based on the sunny / cloudy condition (direct / diffuse ratio) calculated in step S2E, the ratio of solar radiation to illuminance (luminous efficiency) calculated in step S2G, and the window component property information stored in the memory unit 73 (steps S2H and S2I).

[0047] After step S2I, the processor 74 calculates the window surface luminance and glare value (dazzle) in the target room based on the window surface illuminance calculated in step S2H ​​(step S2J).

[0048] After step S2J, the processor 74 compares the window surface luminance / glare value (dazzle) calculated in step S2J with a threshold value stored in the memory unit 73, and determines whether the window surface luminance / glare value (dazzle) exceeds the threshold value (step S2K).

[0049] If it is determined that the window surface luminance / glare value (dazzle) does not exceed the threshold value (step S2K: No), processor 74 proceeds to step S2N. On the other hand, if it is determined that the window surface luminance / glare value (dazzle) exceeds the threshold value (step S2K: Yes), the processor 74 determines whether the current blind angle of the electric blinds 4 is less than the maximum angle (step S2L), as in step S1J.

[0050] If it is determined that the current blind angle is the maximum angle (step S2L: No), the processor 74 proceeds to step S2S. On the other hand, if it is determined that the current blind angle is less than the maximum angle (step S2L: Yes), processor 74 calculates a first blind angle for reducing the window surface luminance / glare value (dazzle) that exceeds the threshold (step S2M). The first blind angle corresponds to the first position according to the present invention.

[0051] After step S2M, the processor 74 compares the desk surface illuminance calculated in step S2I with the threshold value stored in the storage unit 73, and determines whether the desk surface illuminance is less than the threshold value (step S2N).

[0052] When it is determined that the desk surface illuminance is equal to or greater than the threshold value (step S2N: No), the processor 74 proceeds to step S2S. On the other hand, if it is determined that the desk surface illuminance is less than the threshold (step S2N: Yes), the processor 74 calculates a second blind angle to compensate for the deficiency of the desk surface illuminance not meeting the threshold (step S2O). The second blind angle corresponds to the second position according to the present invention.

[0053] After step S2O, the processor 74 controls the operation of the electric blinds 4 and sets the blind angle of the electric blinds 4 to the larger of the first blind angle calculated in step S2M and the second blind angle calculated in step S2O (step S2P: control step).

[0054] After step S2P, processor 74 recalculates the desk surface illuminance in the target room based on the larger of the first blind angle calculated in step S2M and the second blind angle calculated in step S2O, the sunny / cloudy condition (direct / diffuse ratio) calculated in step S2E, the ratio of solar radiation to illuminance (luminous efficiency) calculated in step S2G, and the window component material characteristic information stored in memory unit 73 (step S2Q).

[0055] After step S2Q, processor 74 recalculates the amount of heat entering the target room based on the larger of the first blind angle calculated in step S2M and the second blind angle calculated in step S2O, the outside air temperature obtained in step S2B, the room temperature obtained in step S2C, the amount of solar radiation on the window calculated in step S2D, the sunny / cloudy condition (direct / diffuse ratio) calculated in step S2E, and the window component material characteristic information stored in memory unit 73 (step S2R).

[0056] After step S2R, the processor 74 controls the operation of the lighting device 6 based on the desk surface illuminance calculated in step S2I or the desk surface illuminance recalculated in step S2Q (step S2S: control step).

[0057] After step S2S, processor 74 controls the operation of air conditioner 5 based on the amount of entering heat calculated in step S2F or the amount of entering heat newly calculated in step S2R (step S2T: control step).

[0058] Then, in the indoor environment control method in the second mode, the processor 74 repeatedly executes the processes of steps S2A to S2T described above.

[0059] [Indoor environment control method in the third mode] Next, the indoor environment control method in the third mode will be described. FIG. 4 is a flowchart showing the indoor environment control method in the third mode. First, processor 74 sequentially executes the processes of steps S3A to S3I. Note that the processes of steps S3A to S3I are similar to the processes of steps S2A to S2H and S2J described above, respectively.

[0060] After step S3I, the processor 74, similar to step S2K, compares the window surface luminance / glare value (dazzle) calculated in step S3I with a threshold value stored in the memory unit 73, and determines whether the window surface luminance / glare value (dazzle) exceeds the threshold value (step S3J).

[0061] If it is determined that the window surface luminance / glare value (dazzle) does not exceed the threshold value (step S3J: No), the processor 74 returns to step S3A. On the other hand, if it is determined that the window surface luminance / glare value (dazzle) exceeds the threshold value (step S3J: Yes), the processor 74 determines whether the current blind angle of the electric blinds 4 is less than the maximum angle (step S3K), similar to steps S1J and S2L.

[0062] If it is determined that the current blind angle is the maximum angle (step S3K: No), processor 74 returns to step S3A. On the other hand, if it is determined that the current blind angle is less than the maximum angle (step S3K: Yes), processor 74 calculates a first blind angle for reducing the amount by which the window surface luminance / glare value (dazzle) exceeds the threshold value, as in step S2M (step S3L). The first blind angle corresponds to the first position according to the present invention.

[0063] After step S3L, the processor 74, similar to step S1I, compares the amount of heat entering calculated in step S3F with a threshold value stored in the memory unit 73, and determines whether the amount of heat entering exceeds the threshold value (step S3M).

[0064] If it is determined that the amount of entering heat does not exceed the threshold value (step S3M: No), processor 74 returns to step S3A. On the other hand, if it is determined that the amount of heat entering the room exceeds the threshold (step S3M: Yes), the processor 74 calculates a second blind angle for reducing the amount of heat entering the room that exceeds the threshold (step S3N), similarly to step S1K. The second blind angle corresponds to the second position according to the present invention.

[0065] After step S3N, the processor 74 controls the operation of the electric blinds 4 and sets the blind angle of the electric blinds 4 to the larger of the first blind angle calculated in step S3L and the second blind angle calculated in step S3N (step S3O: control step).

[0066] After step S3O, a room temperature sensor provided in an indoor unit of the air conditioner 5 responds to a change in room temperature in the target room due to step S3O, and the air conditioner 5 automatically conditions the air in the target room without being controlled by the processor 74. Also, an illuminance sensor provided in the lighting device 6 responds to a change in illuminance in the target room due to step S3O, and the lighting device 6 automatically adjusts the brightness in the target room without being controlled by the processor 74.

[0067] In the indoor environment control method in the third mode, the processor 74 repeatedly executes the processes of steps S3A to S3O described above.

[0068] (Other embodiments) Although the embodiments for carrying out the present invention have been described above, the present invention should not be limited to the above-described embodiments. In the above-described embodiment, the photovoltaic element according to the present invention is not limited to the photovoltaic glass 2, and other configurations may be adopted as long as the photovoltaic element is configured to absorb a portion of the sunlight entering the target room and generate electricity.

[0069] In the above-described embodiment, the first to third modes are adopted as the multiple modes according to the present invention, but the number of modes is not limited to three, and may be two, four or more.

[0070] In the above-described embodiment, the control can be executed in accordance with each of the first to third modes, but this is not limited thereto, and the control can be executed in accordance with only one of the modes.

[0071] The flows described in the above embodiment are not limited to the flows in FIGS. 2 to 4, and the order may be changed as long as there is no inconsistency.

[0072] The indoor environment control device of the present invention is an indoor environment control device that performs environmental control within a building, and is equipped with a processor that controls the operation of at least one of a solar shading device that changes the amount of sunlight entering the room by changing its position, an air conditioning device that conditions the room, and a lighting device that irradiates illumination light into the room and adjusts the brightness of the room, and the processor controls the operation of at least one of the solar shading device, the air conditioning device, and the lighting device based on the amount of power generated by a solar power generation element that absorbs a portion of the sunlight entering the room and generates power.

[0073] In the present invention, a processor constituting the indoor environment control device controls the operation of at least one of the solar shading device, the air conditioner, and the lighting device based on the amount of power generated by a photovoltaic power generation element that generates power by absorbing a portion of the sunlight incident on the room (hereinafter referred to as the target room) that is the subject of the indoor environment control. In other words, since the amount of power generated is the amount of power generated by absorbing a portion of the sunlight incident on the room (hereinafter referred to as the target room), an estimated value calculated based on the amount of power generated can be close to an actual measured value. The estimated value is an estimated value used for the indoor environment control, and examples of the estimated value include the amount of heat entering the target room, the illuminance of the desk surface in the target room, and the luminance of the window surface in the target room. Therefore, according to the indoor environment control device of the present invention, by controlling the indoor environment based on the above-mentioned amount of power generation, it is possible to perform optimal environmental control in the target room.

[0074] In addition, in the present invention, in the above-mentioned indoor environment control device, the processor is characterized in that it controls the operation of at least one of the solar shading device, the air conditioning device, and the lighting device based on the amount of solar radiation on the window surface calculated from the amount of power generation.

[0075] Incidentally, the amount of solar radiation on a window surface is a very important value in calculating the above-mentioned estimated value. In the present invention, the processor calculates the amount of solar radiation on the window surface from the amount of power generated by absorbing a portion of the sunlight entering the target room. Therefore, the estimated value calculated based on the amount of solar radiation on the window surface can be closer to the actual measured value. Therefore, more optimal environmental control can be performed in the target room.

[0076] In addition, the present invention is characterized in that in the above-mentioned indoor environment control device, the processor controls the operation of the solar shading device based on at least one of the amount of heat entering the room calculated based on the amount of power generation, the temperature inside the room, and the temperature outside the room, the illuminance of a desk surface inside the room calculated based on the amount of power generation, and the luminance of a window surface inside the room calculated based on the amount of power generation.

[0077] Incidentally, by calculating the amount of heat entering the room, the desk surface illuminance, and the window surface luminance based on the amount of electricity generated by absorbing a portion of the sunlight entering the target room, the amount of heat entering the room, the desk surface illuminance, and the window surface luminance can be made close to the actual measured values. In the present invention, the processor controls the operation of the solar shading device based on at least one of the amount of heat entering the room, the desk surface illuminance, and the window surface luminance.
