[0004] The outdoor air cooling air conditioning control system described in Patent Document 1 requires an outdoor air / return air mixing means for mixing outdoor air with return air from the air conditioning controlled area, and this means must be incorporated in advance into the air conditioning control system of the building, etc. Therefore, introducing it into an existing building, etc., requires a great deal of cost and time.

[0005] The present disclosure has been made in view of such problems, and its purpose is to improve the technology for controlling ventilation equipment. [Means for solving the problem]

[0010] The environmental control system according to the embodiment automatically controls ventilation equipment for ventilating indoor air and outdoor air.

[0011] With the spread of infectious diseases becoming a major social issue, it is necessary to ventilate indoor air with outdoor air at an appropriate frequency to expel pathogens such as viruses and bacteria emitted by people indoors and bring fresh outdoor air indoors. Many existing buildings are equipped with air conditioning equipment to regulate indoor air and air conditioning control systems that automatically control the air conditioning equipment, but do not have systems that automatically control ventilation equipment such as windows. When installing an automatic ventilation control system in such buildings, opening and closing the ventilation equipment completely independently of the existing air conditioning control system can reduce the efficiency of indoor air conditioning by the air conditioning equipment. Furthermore, in order to automatically control the ventilation equipment and air conditioning equipment in a coordinated and coordinated manner, the existing air conditioning control system must be modified or replaced, which can result in significant installation costs and time.

[0012] To solve these problems, in the environmental control system of this embodiment, the ventilation equipment control device controls the opening and closing of the ventilation equipment and indirectly controls the air conditioning equipment by notifying the air conditioning equipment control device of control information for controlling the air conditioning equipment. This allows the ventilation equipment control device to automatically control the ventilation equipment and the air conditioning equipment in a comprehensive and coordinated manner. Even when a ventilation equipment control device is introduced into a building where an air conditioning equipment control device is already installed, by configuring the ventilation equipment control device to notify the control information used by the existing air conditioning equipment control device to control the air conditioning equipment, it is possible to reduce the modifications to the air conditioning equipment control device and the air conditioning equipment that are necessary to introduce the ventilation equipment control device. This can promote the introduction of ventilation equipment control devices.

[0013] 1 shows the configuration of an environmental control system according to an embodiment. The environmental control system 1 includes a window 5, which is an example of ventilation equipment, installed on the exterior wall of a building 2 to be controlled, a ventilation equipment control device 11 that opens and closes the window 5, air conditioning equipment 6 installed in various areas inside the building 2, an air conditioning equipment control device 12 that controls the air conditioning equipment 6, a sensor 7 installed in the building 2, an information providing server 13 that provides weather information and the like, and a communication network 10 that connects these devices.

[0014] The interior of building 2 is divided into perimeter zone 3, which is an area located on the periphery of building 2, and interior zone 4, which is an area located in the center of building 2. Windows 5 are installed in perimeter zone 3. Air conditioning equipment 6 is installed in both perimeter zone 3 and interior zone 4.

[0015] The sensors 7 include temperature sensors, humidity sensors, wind direction sensors, wind speed sensors, rainfall sensors, barometric pressure sensors, pollen sensors, illuminance sensors, solar radiation sensors, etc. installed outdoors, as well as temperature sensors, humidity sensors, illuminance sensors, etc. installed indoors.

[0016] The ventilation equipment control device 11 acquires information such as outdoor temperature, humidity, wind direction, wind speed, rainfall, atmospheric pressure, pollen dispersion amount, illuminance, solar radiation amount, and indoor temperature, humidity, and illuminance detected by the sensor 7. The ventilation equipment control device 11 further acquires public information such as information on outdoor air quality, such as the amount of dispersion of fine particulate matter (PM2.5), yellow sand, pollen, etc., and photochemical smog, as well as weather forecasts and meteorological information, from the information providing server 13. If all of the information can be acquired from the information providing server 13, the sensor 7 may not be provided. The air conditioning equipment control device 12 may acquire at least some of this information from the sensor 7, the information providing server 13, the ventilation equipment control device 11, etc. The ventilation equipment control device 11 may acquire at least some of this information from the air conditioning equipment control device 12.

[0017] Based on this information, the ventilation equipment control device 11 controls the opening and closing of the windows 5. Based on this information, the ventilation equipment control device 11 also generates control information for controlling the air conditioning equipment 6 and notifies the air conditioning equipment control device 12. In this way, the ventilation equipment control device 11 automatically controls the windows 5 and air conditioning equipment 6 installed in the building 2 in a comprehensive and coordinated manner.

[0018] The environmental control system 1 not only automatically controls the windows 5 for the above-described forced ventilation, but also automatically controls the windows 5 and air conditioning equipment 6 in a comprehensive and coordinated manner to achieve a comfortable indoor environment while reducing energy consumption. The environmental control system 1 calculates a comfort index, which is a numerical index of the comfort felt by a person indoors, and controls the windows 5 and air conditioning equipment 6 so that the calculated comfort index falls within a range that makes the person indoors feel comfortable. When outdoor conditions are favorable and it is expected that bringing in outside air will improve the comfort index, the environmental control system 1 opens the windows 5 to let in outside air. When outdoor conditions are unfavorable, such as when it is raining, windy, or there is a lot of pollen or fine particulate matter in the air, the environmental control system 1 closes the windows 5 to block outside air and adjusts the indoor air using the air conditioning equipment 6. This allows the system to actively utilize outside air to maintain comfortable indoor air while minimizing the adverse effects of opening the windows 5 on the indoor environment, thereby reducing energy consumption.

[0019] Ventilation equipment such as windows 5 are generally mechanically opened and closed by a driving means such as a motor, and frequent opening and closing can accelerate deterioration and cause breakdowns. Furthermore, because the opening and closing operation generates noise, it is desirable to reduce the frequency of opening and closing when people indoors are working, in meetings, in classes, sleeping, and so on. Therefore, the environmental control system 1 of this embodiment does not open the window 5 when the outdoor conditions are expected to worsen, even if the outdoor conditions are favorable and the window 5 can be opened. This allows outdoor air to be efficiently introduced while minimizing the adverse effects on the window 5 and people indoors that would be caused by excessive opening and closing of the window 5.

[0020] Indoor air temperature and humidity can vary depending on the compartmentalized areas within the building. In particular, relatively large buildings, such as office buildings where many people work, include peripheral areas equipped with ventilation equipment such as windows 5 and central areas without ventilation equipment. The area without ventilation equipment is less directly affected by the opening and closing of the ventilation equipment, so a large difference in the environment between the two areas can occur when the ventilation equipment is opened. Therefore, the environmental control system 1 of this embodiment controls the windows 5 and air conditioning equipment 6 according to different control standards for the perimeter zone 3 equipped with windows 5 and the interior zone 4 without windows 5.

[0021] FIG. 2 shows an example of a window controlled by an environmental control system according to an embodiment. FIG. 2(a) is a schematic diagram of a window 5 in a closed state, viewed from above. A building 2 includes not only openable windows 5 but also non-openable windows 8. The openable windows 5 have a right-angled triangular shape that protrudes outward beyond the non-openable windows 8. FIG. 2(b) is a schematic diagram of a window 5 in an open state, viewed from above. The window 5 is opened by rotating an opening / closing unit 9 attached to a side perpendicular to the exterior wall. This structure allows the wind blowing along the exterior wall of the building 2 to be efficiently introduced indoors. Unlike conventional windows, the structure prevents wind from blowing directly into the building through the opening created by the rotation of the opening / closing unit 9, thereby preventing documents and dust from being blown away by the wind blowing indoors. While FIGS. 1 and 2 show an example in which multiple windows 5 with their hypotenuses aligned in the same direction are provided, windows 5 with their left and right reversed configurations may also be included. In this case, since there are windows that open leftward and windows that open rightward when viewed from indoors to outdoors, the ventilation equipment control device 11 may determine which windows 5 to open based on the outdoor wind speed or direction. For example, when the wind speed is faster than a predetermined value, the window 5 that opens in the opposite direction to the wind direction may be opened, and when the wind speed is slower than the predetermined value, the window 5 that opens in the same direction as the wind direction may be opened. This allows outside air to be efficiently introduced indoors when the wind is weak. It also reduces the impact of wind on the indoors when the wind is strong. The window 5 may be a typical horizontal sliding window, double sliding window, casement window, louvered window, or the like, or it may be a window with any other opening and closing method or shape.

[0022] FIG. 3 is a flowchart showing the steps of a control method according to an embodiment. First, in step S10, the ventilation equipment control device 11 sets an operation mode according to a predetermined period, such as a day of the week or a time period. Because the environmental control system 1 of this embodiment controls an office building, the number of people in building 2 and the situation within building 2 change significantly over time depending on the work schedule of the company occupying the building. Therefore, the ventilation equipment control device 11 can set multiple operation modes to suit the company's work schedule. In this embodiment, five operation modes are provided: "weekday daytime," which corresponds to working hours; "overtime," which corresponds to a time period when some people work overtime after working hours; "nighttime," which corresponds to a time period when almost no one is present after overtime; "dawn," which corresponds to a time period when people are preparing before work; and "holiday," which corresponds to a time period when almost no one is present throughout the day.

[0023] In the "weekday daytime" operating mode, the ventilation equipment control device 11 calculates the comfort index in real time and automatically controls the ventilation equipment such as windows 5 and the air conditioning equipment 6 so that the comfort index falls within a predetermined control range.

[0024] Even in the "overtime" operating mode, the ventilation equipment control device 11 automatically controls the windows 5 and the air conditioning equipment 6 so that the comfort index falls within a predetermined control range. The "overtime" operating mode may be the same as the "weekday daytime" operating mode. Because it is expected that there will be fewer people in the building 2 during overtime than during working hours, the control range of the comfort index may be wider than in the "weekday daytime" operating mode. Furthermore, because it is expected that the impact of noise caused by opening and closing the windows 5 will be relatively smaller during overtime, the conditions for opening the windows 5 may be relaxed compared to the "weekday daytime" operating mode.

[0025] In the "night" operating mode, the ventilation equipment control device 11 keeps the windows 5 closed and turns off the air conditioning equipment 6. During the midsummer period (for example, from July to September), in order to reduce the load on the air conditioning equipment 6, the ventilation equipment control device 11 executes a "night purge function" in the early morning when the outside air temperature is lower than during the day, to bring outside air indoors and lower the temperature inside the building 2. The night purge function will be described in detail later.

[0026] In the "daylight" operating mode, the ventilation equipment control device 11 automatically controls the ventilation equipment, such as the windows 5, and the air conditioning equipment 6 so that the comfort index falls within a predetermined control range as work hours approach. The "daylight" operating mode may be the same as the "weekday daytime" operating mode. Since the impact of noise caused by opening and closing the windows 5 is thought to be relatively small during the daylight hours, the conditions for opening the windows 5 may be more relaxed than in the "weekday daytime" operating mode.

[0027] In the "holiday" operating mode, the ventilation equipment control device 11 keeps the windows 5 closed and turns off the air conditioning equipment 6. If there are people at work in the building 2 on a holiday, the windows 5 or air conditioning equipment 6 may be manually controlled, or the ventilation equipment control device 11 may automatically control the windows 5 and air conditioning equipment 6 in the area where there are people at work, as in the "weekday daytime" operating mode.

[0028] If multiple companies or the like are located in the building 2 to be controlled, different operation modes may be set for each company. In addition to days of the week and time periods, different operation modes may be set for periods such as hours, days, weeks, months, and seasons. The start time of the "dawn" or "weekday daytime" operation mode on a work day after a holiday may be set earlier than the start time of the "dawn" or "weekday daytime" operation mode on other days. Operation mode settings may be accepted by a person in charge. For example, settings for holidays other than those on the calendar may be accepted.

[0029] By being able to set different operating modes for each specified period, it is possible to automatically control the ventilation equipment and air conditioning equipment in accordance with more appropriate control standards depending on the situation inside Building 2. This makes it possible to improve the environment inside Building 2 while suppressing the adverse effects and energy consumption of natural ventilation.

[0030] In step S12, the ventilation equipment control device 11 acquires detection information from the sensor 7, public information from the information providing server 13, and device information from the air conditioning equipment control device 12.

[0031] In step S14, the ventilation equipment control device 11 calculates a comfort index for each floor of the building 2 and for each area on each floor. The comfort index may be, for example, the predicted mean vote (PMV) defined by the international standard ISO7730 of the International Organization for Standardization (ISO). The PMV value is calculated based on four environmental factors that determine thermal sensation (temperature, humidity, wind speed, and thermal radiation) and two human body factors (metabolic rate and amount of clothing). The PMV value expresses human thermal comfort on a scale of -3 to 3, with 0 representing a thermally neutral state. The comfort index is calculated based on the Standard Effective Temperature (SET) defined by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). * The comfort index may be an index determined by other standards, or may be an index calculated by a formula uniquely determined in the environmental control system 1.

[0032] When calculating the PMV value as the comfort index, the ventilation equipment control device 11 acquires the temperature and humidity used to calculate the PMV value in real time from the sensor 7. If multiple sensors 7 for detecting temperature, humidity, etc. are installed in the same area, the average value of the values ​​measured by those sensors 7 may be used. Furthermore, values ​​measured by sensors 7 installed in an adjacent area or another area on the same floor may be used as values ​​for temperature, humidity, etc. in an area where no sensor 7 is installed.

[0033] The clothing amount, metabolic rate, external work, mean radiant temperature, and air velocity used to calculate the PMV value are considered to vary little over time, so preset fixed values ​​may be used as these values. The fixed values ​​may be set for a predetermined period, such as hourly, daily, weekly, monthly, or seasonally. For example, the metabolic rate may be set higher at the start of a shift. The fixed values ​​may be set for each floor or area of ​​the building 2. For example, different fixed values ​​may be set for the perimeter zone 3 and the interior zone 4. Also, different fixed values ​​may be set for areas with windows 5 and areas without windows 5. In this case, the comfort index is calculated according to different calculation standards for the perimeter zone 3 with windows 5 and the interior zone 4 without windows. This allows the difference in the environments between the perimeter zone 3 and the interior zone 4 to be accurately evaluated and the windows 5 and air conditioning equipment 6 to be controlled accordingly.

[0034] Fixed values ​​may be set based on the size, height, shape, volume, and type of interior materials of each area, the type, number, and location of devices and equipment installed in each area, and the number, attributes, and behavior of people present in each area. The fixed values ​​may be changed manually or automatically in response to changes in the conditions of each area. For example, the amount of clothing worn by people in each area may be calculated based on the outside temperature before work begins. Alternatively, a person in charge may visually check the amount of clothing worn by people in each area and input the amount of clothing worn by people in each area into the ventilation equipment control device 11. The values ​​of these variables may be changed in real time. For example, the ventilation equipment control device 11 may analyze images taken by cameras installed in each area to obtain the amount of clothing worn, metabolic rate, external work, and the like. Measurement values ​​detected by the sensor 7 may be used as the values ​​of the average radiant temperature and airflow velocity.

[0035] In step S16, the ventilation equipment control device 11 checks the outdoor weather. The ventilation equipment control device 11 refers to the detection information acquired from the sensor 7 and checks whether the outdoor weather meets predetermined conditions that prohibit opening of the window 5. The predetermined conditions are, for example, conditions related to wind speed, rainfall, and hail.

[0036] The ventilation equipment control device 11 calculates the average wind speed over a predetermined period (e.g., 10 minutes) based on wind speed measurements obtained from the wind speed sensor every predetermined time (e.g., 3 seconds). When the average wind speed exceeds a predetermined value (e.g., 3 m / s) or more, the ventilation equipment control device 11 prohibits the window 5 from opening and closes the window 5 if it is open. When the instantaneous wind speed exceeds a predetermined value (e.g., 8 m / s) a predetermined number of times (e.g., 3 times) during the predetermined period (e.g., 10 minutes), the ventilation equipment control device 11 prohibits the window 5 from opening and closes the window 5 if it is open. The ventilation equipment control device 11 prohibits the window 5 from opening until the wind speed remains below a predetermined value (e.g., 1 m / s) for a predetermined period (e.g., 1 hour). When the wind speed remains below the predetermined value for a predetermined period or more, the ventilation equipment control device 11 lifts the prohibition on the window 5 from opening and returns to normal operation.

[0037] The ventilation equipment control device 11 prohibits the opening of the window 5 when the rainfall measurement value obtained from the rainfall sensor every predetermined time (for example, 1 second) exceeds a predetermined value (for example, 1 mm) a predetermined number of times (for example, 3 times), and closes the window 5 if it is open. The ventilation equipment control device 11 prohibits the opening of the window 5 until the rainfall remains below a predetermined value (for example, 0 mm) for a predetermined period of time (for example, 30 minutes). When the rainfall remains below the predetermined value for the predetermined period of time or more, the ventilation equipment control device 11 lifts the prohibition on the opening of the window 5 and returns to normal operation.

[0038] When the number of hail detections per predetermined time period (e.g., 1 second) obtained from the hail sensor exceeds a predetermined number (e.g., 1 time) in a predetermined period (e.g., 10 seconds), the ventilation equipment control device 11 prohibits the opening of the window 5, and closes the window 5 if it is open. The ventilation equipment control device 11 prohibits the opening of the window 5 until the number of hail detections remains below a predetermined value (e.g., 0 times) for a predetermined period (e.g., 30 minutes). When the number of hail detections remains below the predetermined value for a predetermined period, the ventilation equipment control device 11 lifts the prohibition on the opening of the window 5 and returns to normal operation.

[0039] If the window 5 has a shape that makes it difficult for wind, rain, hail, etc. to enter the interior, such as a sliding window, the ventilation equipment control device 11 does not have to prohibit the opening of the window 5 based on wind speed, rainfall, hailfall, etc. Furthermore, if the outdoor wind speed is below a predetermined value, the ventilation equipment control device 11 does not have to prohibit the opening of the window 5 based on rainfall, hailfall, etc.

[0040] In step S18, the ventilation equipment control device 11 checks the quality of the outdoor air. The ventilation equipment control device 11 refers to the detection information obtained from the sensor 7 and the public information obtained from the information providing server 13 to check whether the air quality meets predetermined conditions that prohibit opening the window 5. The predetermined conditions are, for example, conditions related to pollen and PM2.5.

[0041] The ventilation equipment control device 11 detects whether the measured value of the amount of pollen obtained from the pollen sensor every predetermined time (for example, 1 second) exceeds a predetermined value (for example, 50 particles / cm) for a predetermined number of times (for example, 3 times). 3 ), the ventilation equipment control device 11 prohibits the window 5 from being opened, and closes the window 5 if it is open. 3 ) continues for a predetermined period (for example, one hour). When the amount of pollen continues to be less than the predetermined value for a predetermined period, the ventilation equipment control device 11 releases the prohibition on opening the window 5 and returns to normal operation.

[0042] The ventilation equipment control device 11 determines whether the amount of PM2.5 obtained from the information providing server 13 is equal to or exceeds a predetermined value (for example, 35 μg / m 3 ), the ventilation equipment control device 11 prohibits the window 5 from being opened, and closes the window 5 if the amount of PM2.5 is a predetermined value (for example, 35 μg / m 3 ) continues for a predetermined period (for example, one hour). When the amount of PM2.5 continues to be less than the predetermined value for a predetermined period, the ventilation equipment control device 11 releases the prohibition on opening the window 5 and returns to normal operation.

[0043] For windows 5 installed on higher floors, the ventilation equipment control device 11 does not have to prohibit the opening of the windows 5 based on the outdoor air quality. Furthermore, when the outdoor wind speed is below a predetermined value, the ventilation equipment control device 11 does not have to prohibit the opening of the windows 5 based on the outdoor air quality. The ventilation equipment control device 11 may prohibit the opening of the windows using a separate sensor for higher floors.

[0044] In step S20, the ventilation equipment control device 11 checks the public information acquired from the information providing server 13. The ventilation equipment control device 11 refers to the public information acquired from the information providing server 13 and checks whether the information meets a predetermined condition that prohibits opening the window 5 because the outdoor weather is expected to worsen. The predetermined condition is, for example, a condition related to the probability of precipitation or rainfall forecast.

[0045] The ventilation equipment control device 11 prohibits the opening of the window 5 when the probability of precipitation after a predetermined time (for example, one hour) is equal to or greater than a predetermined value (for example, 50%), and closes the window 5 if it is open. The ventilation equipment control device 11 prohibits the opening of the window 5 until the probability of precipitation falls below a predetermined value (for example, 50%). When the probability of precipitation falls below the predetermined value, the ventilation equipment control device 11 lifts the prohibition on the opening of the window 5 and returns to normal operation.

[0046] The ventilation equipment control device 11 prohibits the opening of the window 5 when the predicted rainfall after a predetermined time (for example, one hour) is equal to or greater than a predetermined value (for example, 10 mm), and closes the window 5 if it is open. The ventilation equipment control device 11 prohibits the opening of the window 5 until the predicted rainfall falls below a predetermined value (for example, 10 mm). When the probability of precipitation falls below the predetermined value, the ventilation equipment control device 11 lifts the prohibition on the opening of the window 5 and returns to normal operation.

[0047] The conditions for prohibiting the opening of the window 5 may be set individually depending on the shape and position of the window 5. In addition, the conditions for prohibiting the opening of the window 5 may be set depending on the outdoor wind speed, wind direction, and the like.

[0048] In step S22, the ventilation equipment control device 11 refers to the indoor and outdoor conditions and checks whether the conditions for opening and closing the window 5 are met. If opening of the window 5 is prohibited in the operating mode set in step S10, or if opening of the window 5 is prohibited in steps S16, S18, and S20, the ventilation equipment control device 11 does not perform automatic control of the window 5 (N in S22). By closing the window 5 when the outdoor conditions are not good, the adverse effects of outside air on the indoor air can be reduced. Furthermore, by not opening the window 5 when there is a possibility that the outdoor conditions will worsen, the adverse effects of excessive opening and closing on the mechanism that drives the window 5 and on people indoors can be reduced. If opening of the window 5 is not prohibited, the ventilation equipment control device 11 determines the control content of the window 5 and the air conditioning equipment 6 in accordance with the control criteria.

[0049] 4 shows examples of control standards in the environmental control system according to this embodiment. Control standard A is applied in seasons other than midwinter (for example, from February to November). Control standard B is applied when opening of the windows 5 is prohibited in seasons other than midwinter (for example, from February to November). Control standard C is applied in midwinter (for example, from December to January) and in seasons other than midwinter (for example, from February to November) when the outside air temperature is not within a predetermined temperature range, which will be described later. Control standard D is applied when only the windows 5 are controlled without using the air conditioning equipment 6.

[0050] The target value for the PMV value, which is the comfort index, is 0, which represents a thermally neutral state. The ventilation equipment controller 11 controls the windows 5 and the air conditioning equipment 6 so that the comfort index falls within a control range between the lower limit and upper limit of the control range. The window control lower limit and upper limit are used by the ventilation equipment controller 11 to automatically control the windows 5. The air conditioning control lower limit and upper limit are used by the ventilation equipment controller 11 to automatically control the air conditioning equipment 6. Normally, the "intermediate mode" value is used, and depending on the situation in building 2 and requests from people in building 2, the mode can be switched to either a "comfort priority mode" that prioritizes comfort and refrains from opening the windows 5, or a "passive priority mode" that opens the windows 5 as much as possible to save energy.

[0051] When control standard A is applied, the ventilation equipment control device 11 automatically controls the windows 5 based on the comfort index when the outside air temperature is within a predetermined temperature range where the indoor comfort index can be expected to improve by taking in outside air indoors. The predetermined temperature range may be, for example, a temperature that is equal to or higher than a temperature that is a predetermined temperature (e.g., 4 degrees) lower than the temperature at which the comfort index becomes the lower limit of the control range, and equal to or lower than a temperature that is a predetermined temperature (e.g., 0 degrees) lower than the temperature at which the comfort index becomes the upper limit of the control range.

[0052] In control standard A, the ventilation equipment controller 11 does not perform automatic control of the window 5 while the comfort index is between the window control lower limit and the window control upper limit. If the comfort index rises and exceeds the window control upper limit while the window is closed, the ventilation equipment controller 11 opens the window 5. If the comfort index continues to rise and exceeds the control range upper limit, the ventilation equipment controller 11 closes the window 5. If the comfort index falls and falls below the window control lower limit, the ventilation equipment controller 11 closes the window 5.

[0053] In control standard A, the ventilation equipment controller 11 turns on the air conditioning equipment 6 when the comfort index is higher than the air conditioning control upper limit value and lower than the air conditioning control lower limit value. While the air conditioning equipment 6 is on, the operation of the air conditioning equipment 6 is automatically controlled by the air conditioning equipment controller 12. If the comfort index rises or falls to 0 while the air conditioning equipment 6 is on, the ventilation equipment controller 11 turns off the air conditioning equipment 6.

[0054] When control standard B is applied, the ventilation equipment control device 11 keeps the windows 5 closed and controls only the air conditioning equipment 6. The method of controlling the air conditioning equipment 6 is the same as that of control standard A.

[0055] When control standard C is applied, the ventilation equipment controller 11 keeps the windows 5 closed and does not control the on / off of the air conditioning equipment 6. The ventilation equipment controller 11 calculates the temperature at which the comfort index is 0 and instructs the air conditioning equipment controller 12 to set the calculated temperature as the target temperature. The operation of the air conditioning equipment 6 is automatically controlled by the air conditioning equipment controller 12.

[0056] When control standard D is applied, the ventilation equipment control device 11 does not control the air conditioning equipment 6, but controls only the window 5. The method of controlling the window 5 is the same as that of control standard A.

[0057] As mentioned above, the comfort index is calculated for each area, and is calculated according to different calculation standards for the perimeter zone 3 and the interior zone 4. By controlling the windows 5 and air conditioning equipment 6 based on the comfort index calculated in this way, it is possible to reduce the environmental differences between areas and improve the comfort of the entire interior of the building 2.

[0058] If it is determined in step S22 that the window 5 is to be automatically controlled (Y in S22), then in step S23 the ventilation equipment control device 11 determines the opening degree of the window 5 based on the outdoor temperature and wind speed. The ventilation equipment control device 11 refers to a table that defines a predetermined correspondence relationship between the outdoor temperature and wind speed and the opening degree of the window 5, and determines the opening degree of the window 5 based on the measured value of the outside air temperature acquired from the temperature sensor and the measured value of the wind speed acquired from the wind speed sensor.

[0059] FIG. 5 shows an example of an opening degree table that is referenced to determine the opening degree of the window 5. The opening degree table defines the correspondence relationship between the outdoor temperature and wind speed and the opening degree of the window 5. The wind speed may be the average value of wind speed measurements obtained from a wind speed sensor every predetermined time (e.g., 3 seconds) over a predetermined period (e.g., 10 minutes). The opening degree tables include a first table that is referenced when ventilation is given priority, and a second table that is referenced when maintaining indoor comfort is given priority. The two opening degree tables differ in the correspondence relationship between the outdoor temperature and the opening degree of the window 5, and the first table has a wider range of outdoor temperatures associated with larger opening degrees than the second table.

[0060] In the first table, when the outdoor temperature is below 17°C or above 28°C, the opening degree of window 5 is set to 0% for all wind speed ranges. In the second table, when the outdoor temperature is below 19°C or above 26°C, the opening degree of window 5 is set to 0% for all wind speed ranges. For other temperature ranges, the opening degree of window 5 is determined according to the wind speed. The smaller the wind speed, the larger the opening degree of window 5, and the larger the wind speed, the smaller the opening degree of window 5.

[0061] For example, when the wind speed is 0 to 0.5 m / s, in the first table, if the outdoor temperature is below 17°C, the opening degree of window 5 is set to 0%, if the outdoor temperature is 17 to 18.5°C, the opening degree of window 5 is set to 25%, if the outdoor temperature is 18.5 to 20°C, the opening degree of window 5 is set to 50%, if the outdoor temperature is 20 to 28°C, the opening degree of window 5 is set to 100%, and if the outdoor temperature is 28°C or higher, the opening degree of window 5 is set to 0%. When the wind speed is 0 to 0.5 m / s, in the second table, if the outdoor temperature is below 19°C, the opening degree of window 5 is set to 0%, if the outdoor temperature is 19 to 20.5°C, the opening degree of window 5 is set to 25%, if the outdoor temperature is 20.5 to 22°C, the opening degree of window 5 is set to 50%, if the outdoor temperature is 22 to 26°C, the opening degree of window 5 is set to 100%, and if the outdoor temperature is 26°C or higher, the opening degree of window 5 is set to 0%.

[0062] When the wind speed is 1 to 2 m / s, in the first table, if the outdoor temperature is below 17.5°C, the opening degree of window 5 is set to 0%, if the outdoor temperature is 17.5 to 19°C, the opening degree of window 5 is set to 25%, if the outdoor temperature is 19 to 20.5°C, the opening degree of window 5 is set to 50%, if the outdoor temperature is 20.5 to 28°C, the opening degree of window 5 is set to 100%, and if the outdoor temperature is 28°C or higher, the opening degree of window 5 is set to 0%. When the wind speed is 1 to 2 m / s, in the second table, if the outdoor temperature is below 19.5°C, the opening degree of window 5 is set to 0%, if the outdoor temperature is 19.5 to 21°C, the opening degree of window 5 is set to 25%, if the outdoor temperature is 21 to 22.5°C, the opening degree of window 5 is set to 50%, if the outdoor temperature is 22.5 to 26°C, the opening degree of window 5 is set to 100%, and if the outdoor temperature is 26°C or higher, the opening degree of window 5 is set to 0%.

[0063] When the wind speed is 3 to 4 m / s, in the first table, the window 5 is opened to 0% when the outdoor temperature is below 18.5°C, to 25% when the outdoor temperature is between 18.5 and 20°C, to 50% when the outdoor temperature is between 20 and 28°C, and to 0% when the outdoor temperature is 28°C or higher. There is no temperature range in which the window 5 is opened to 100%. When the wind speed is 3 to 4 m / s, in the second table, the window 5 is opened to 0% when the outdoor temperature is below 20.5°C, to 25% when the outdoor temperature is between 20.5 and 22°C, to 50% when the outdoor temperature is between 22 and 26°C, and to 0% when the outdoor temperature is 26°C or higher. There is no temperature range in which the window 5 is 100% open.

[0064] When the wind speed is 5 to 6 m / s, in the first table, the window 5 is opened to 0% when the outdoor temperature is below 19.5°C, the window 5 is opened to 25% when the outdoor temperature is between 19.5 and 28°C, and the window 5 is opened to 0% when the outdoor temperature is 28°C or higher. There is no temperature range in which the window 5 is opened to 50% or 100%. When the wind speed is 5 to 6 m / s, in the second table, the window 5 is opened to 0% when the outdoor temperature is below 21.5°C, the window 5 is opened to 25% when the outdoor temperature is between 21.5 and 26°C, and the window 5 is opened to 0% when the outdoor temperature is 26°C or higher. There is no temperature range in which the window 5 is opened to 50% or 100%.

[0065] When the wind speed is 6 m / s, the opening degree of the window 5 is set to 0% in all temperature ranges in both the first table and the second table.

[0066] When the wind speed is high, the range of outdoor temperatures associated with the same opening degree is the same or narrower than when the wind speed is low. At the same temperature, when the wind speed is high, the opening degree is the same or smaller than when the wind speed is low. At the same wind speed, when the outdoor temperature is high, the opening degree is the same or larger than when the outdoor temperature is low. This allows efficient ventilation by opening the window 5 at an appropriate opening degree while minimizing adverse effects on the indoors.

[0067] As described above, the ventilation equipment control device 11 of this embodiment controls the opening degree of the window 5 using an opening degree table that defines the correspondence between the outdoor temperature and wind speed and the opening degree of the window 5, thereby simplifying the control and enabling it to be achieved with an inexpensive device. Furthermore, even if more operation modes are provided in addition to the first and second tables, the control can be prevented from becoming complicated. Furthermore, because the settings can be easily changed, the opening degree of the window 5 can be controlled appropriately depending on the situation.

[0068] Even if the outdoor temperature is a temperature corresponding to 0% opening of window 5 in the opening degree table, if the indoor temperature is equal to or higher than a predetermined value, ventilation equipment control device 11 may open window 5. In this case, window 5 may be closed when a predetermined time has elapsed or when the indoor temperature falls below the predetermined value.

[0069] The ventilation equipment control device 11 may also control the opening degree of the window 5 based on the indoor air quality. For example, the carbon dioxide concentration of the indoor air may be detected by a sensor, and the opening degree of the window 5 may be increased when the carbon dioxide concentration is high compared to when the carbon dioxide concentration is low. Furthermore, pollutants other than carbon dioxide may be detected by a sensor, and the opening degree of the window 5 may be increased when a pollutant is detected compared to when no pollutant is detected. An operating mode may be provided for quickly discharging carbon dioxide and pollutants to the outdoors. In this case, even if the opening of the window 5 is prohibited, the prohibition may be lifted, the window 5 may be opened, and the window 5 may be closed when a predetermined time has elapsed, when the carbon dioxide concentration falls below a predetermined value, or when pollutants are no longer detected.

[0070] The ventilation equipment control device 11 may also control the opening degree of the window 5 based on radiant heat from outdoors. For example, the temperature of the indoor wall surface may be detected by a sensor as information indicating the radiant heat from outdoors, and the opening degree of the window 5 may be increased when the temperature of the indoor wall surface is high, i.e., when there is a lot of radiant heat from outdoors, compared to when the temperature of the indoor wall surface is low.

[0071] The ventilation equipment control device 11 may also control the opening degree of the window 5 based on the outdoor wind direction. For example, the outdoor wind direction may be detected by a sensor, and the opening degree of the window 5 into which the wind blows from the outdoors may be set smaller than the opening degree of the other windows 5.

[0072] In step S24, the ventilation equipment control device 11 automatically controls the window 5. The ventilation equipment control device 11 opens the window 5 at the opening degree determined in step S23. If the outdoor temperature or wind speed changes while the window 5 is open, the ventilation equipment control device 11 changes the opening degree of the window 5 by referring to the opening degree table. If the outdoor temperature or wind speed value corresponding to an opening degree different from the current window 5 opening degree continues for a predetermined time (e.g., 30 minutes) or more, the ventilation equipment control device 11 changes the opening degree of the window 5 to one that corresponds to that state. This makes it possible to prevent excessive changes in the opening degree of the window 5. Hysteresis may be provided by using different outdoor temperature or wind speed thresholds when increasing and decreasing the opening degree of the window 5.

[0073] When opening the windows 5, the ventilation equipment control device 11 determines the number and positions of the windows 5 to be opened based on the outdoor wind speed or wind direction.

[0074] The ventilation equipment control device 11 calculates the average wind speed over a predetermined period (e.g., 10 minutes) based on wind speed measurements obtained from the wind speed sensor every predetermined time (e.g., 3 seconds), and determines the number and positions of the windows 5 to open based on the average wind speed. For example, the ventilation equipment control device 11 opens all of the windows 5 when the average wind speed is less than a first threshold (e.g., 1.5 m / s), and opens half of the windows 5 on each side when the average wind speed is equal to or greater than the first threshold and less than a second threshold (e.g., 3 m / s). As described above, the ventilation equipment control device 11 closes the windows 5 when the average wind speed exceeds a predetermined value (e.g., 3 m / s) and prohibits the windows 5 from opening until the wind speed remains at or below a predetermined value (e.g., 1 m / s) for a predetermined period (e.g., 1 hour). Similarly, when returning from a state in which half of the windows 5 are open to a state in which all of the windows 5 are open, the ventilation equipment control device 11 opens the remaining half of the windows 5 after the wind speed has remained below a predetermined value (e.g., 1 m / s) for a predetermined period of time (e.g., 1 hour).

[0075] The ventilation equipment control device 11 calculates the average wind direction over a predetermined period (e.g., 10 minutes) based on the wind direction measurement values ​​obtained from the wind direction sensor, and if the average wind direction exceeds a threshold value twice consecutively, determines the positions of the windows 5 to open based on that wind direction. The ventilation equipment control device 11 may also determine the positions of the windows 5 to open based on the relationship between the opening direction of the windows 5 and the wind direction. For example, when the wind speed is faster than a predetermined value, the windows 5 that open in the opposite direction to the wind direction may be opened, and when the wind speed is slower than the predetermined value, the windows 5 that open in the same direction as or perpendicular to the wind direction may be opened. If the average wind direction does not exceed the threshold value twice consecutively, the ventilation equipment control device 11 may determine that the wind direction is not constant and open all of the windows 5.

[0076] The ventilation equipment control device 11 may determine the number and positions of the windows 5 to open for each perimeter zone 3. The ventilation equipment control device 11 may determine the number and positions of the windows 5 to open for each floor. The ventilation equipment control device 11 may classify multiple windows 5 into groups and determine the groups of windows 5 to open.

[0077] In step S25, the ventilation equipment control device 11 notifies the air conditioning equipment control device 12 of the open / closed state of the window 5. The air conditioning equipment control device 12 controls the air conditioning equipment 6 according to the open / closed state of the window 5 notified by the ventilation equipment control device 11. The air conditioning equipment control device 12 may determine the control mode of the air conditioning equipment 6 according to whether the window 5 is open or not. For example, if the air conditioning equipment 6 has a function of ventilating outdoor air and indoor air, the ventilation function of the air conditioning equipment 6 may be turned off or reduced when the window 5 is open. This can reduce energy consumption. When the window 5 is open, the air conditioning equipment control device 12 may determine the control mode of the air conditioning equipment 6 according to the opening degree of the window 5, the number and position of the open windows 5, etc. The ventilation equipment control device 11 may determine the control mode of the air conditioning equipment 6 according to the open / closed state of the window 5 and notify the air conditioning equipment control device 12 of the determined control mode.

[0078] In step S26, the ventilation equipment control device 11 determines the set temperature of the air conditioning equipment 6 when not automatically controlling the windows 5. The ventilation equipment control device 11 calculates the indoor temperature at which the comfort index becomes 0 using a formula for calculating the comfort index.

[0079] In step S27, the ventilation equipment control device 11 notifies the calculated temperature as the set temperature to the air conditioning equipment control device 12. The air conditioning equipment control device 12 automatically controls each air conditioning equipment 6 based on the notified set temperature.

[0080] In step S28, the ventilation equipment control device 11 checks the control range of the comfort index. If the calculated comfort index is not within the control range, the above control is continued so that the comfort index falls within the control range.

[0081] When the night purge function is executed in the "night" operating mode described above, the ventilation equipment control device 11 opens the windows 5 to let outside air into the room if the outdoor temperature is below a predetermined temperature (e.g., 27°C) and the indoor temperature is above a predetermined temperature, at least a predetermined time (e.g., three hours) before work hours. The control of the windows 5 may be performed for each floor or area of ​​the building 2. If the outdoor temperature becomes higher than the indoor temperature while the windows 5 are open, the ventilation equipment control device 11 closes the windows 5. If the outdoor temperature subsequently becomes lower than the indoor temperature, the ventilation equipment control device 11 may open the windows 5 again. If the above-described condition prohibiting the opening of the windows 5 is met, the ventilation equipment control device 11 does not open the windows 5. If the prohibition on opening the windows 5 is lifted, the ventilation equipment control device 11 may open the windows 5. When opening the windows 5, the ventilation equipment control device 11 may determine the number or positions of the windows 5 to open based on the wind speed or wind direction, as described above. Even if the wind speed is relatively fast and half of the windows 5 are open, all windows 5 in areas where the impact of the wind is small, such as conference rooms, may be opened. This allows the heat accumulated on the exterior walls and other parts of the building 2 to be cooled by the cool air in the early morning, thereby reducing the load on the air conditioning equipment 6 and reducing energy consumption.

[0090] In steps S16, S18, and S20, the control mode determination unit 65 determines whether or not the conditions for prohibiting the opening of the window 5 are met.
