<<Embodiment>>
Embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 is a diagram schematically showing the apparatus and method for providing indoor air quality information according to this embodiment.

The apparatus for providing indoor air quality information shown in FIG. a providing unit (10) for providing comparative information comparing the information with air quality information of a space (30) elsewhere.

More specifically, in FIG. 1, indoor air quality information of a target building (20), which is an example of the target space (20), is acquired by a sensor (21). Indoor air quality information of at least one other building (30), which is an example of the other space (30), is also obtained by the sensor (31). These indoor air quality information are transmitted through the Internet line or the like using the cloud (40) and provided to the providing unit (10). Here, the indoor air quality information of the target space (20) may be directly transmitted to the providing unit (10) without going through the cloud (40).

The indoor air quality information in the target building (20) is also provided to the cloud (40). The indoor air quality information providing apparatus of the present disclosure can also be used in a specific other building (30) that is one of the other spaces (30). In that case, from the standpoint of the other building (30), the target building (20) is one of the "other spaces."

The providing unit (10) may use a handheld terminal including a smartphone and a tablet, a general computer monitor, or the like, or may be equipped with a dedicated device including a display screen. FIG. 1 shows a tablet (10) as an example of the providing unit (10). The providing unit (10) may be installed in the target building (20) or may be carried by a serviceman who maintains the equipment.

According to such a system, in addition to providing the air quality information of the target space (20) independently, it is possible to provide relative information compared with the air quality information of other spaces (30).

The comparison information may be based on the air quality information of the target space (20) and the other space (30) itself or the scores obtained by evaluating the air quality information. A score is a value evaluated by a predetermined method for each item such as carbon dioxide concentration. For example, the carbon dioxide concentration may be scored based on the proportion of time during which the predetermined threshold is not exceeded within a certain period of time (90% of the time, when the threshold is not exceeded, 90 points, etc.). Also, for the PM2.5 concentration, points may be given based on the range of values, such as 100 points for 0 to 5 ppm and 90 points for 5 to 10 ppm. Furthermore, an overall score may be given based on the score of each item.

Further, the comparison method may include comparison of the value of the object space with the average value, display by the deviation value, ranking display in order, classification display in a plurality of stages, and the like. . It may be displayed visually using various graphs, colors, photographs, and the like.

FIG. 2 shows an example of display in the providing section (10). In FIG. 2, the air quality in the target space (20) and the other space (30) is measured based on temperature and humidity (Tem/Hum), carbon dioxide concentration (CO ₂ ), total volatile organic compounds (TVOC: Total Volatile Organic Compounds), PM2.5 concentration, and formaldehyde concentration (HCHO). Furthermore, the air quality deviation value is calculated based on the five items, and a total of six items are displayed. Items related to air quality are not limited to the above, and other information such as CO (carbon monoxide), PM10, _O3 (ozone), _NO2 (nitrogen dioxide), _SO2 (sulfur dioxide), etc. may contain

In the example of FIG. 2, the air quality deviation value of the target space (20) labeled "○○ Building" is 34. Also, when the air quality deviation values in a total of 2365 spaces including the target space (20) and the other space (30) are ranked, the ○○ building is ranked 2164th. Numerical values and building names are omitted except for the target space (20), "○○ Building".

In this way, by displaying the indoor air quality of the target space (20) as a ranking compared to other spaces (30), it is possible to know the target for maintenance, improvement, etc. of the cleanliness level of the target space. can. Accordingly, the users of the target building (20) are more likely to understand the products and/or services they need or want. Also, product and/or service providers are more likely to encourage purchases.

In this example, ranking by deviation value is displayed, but ranking by ranking individual items such as carbon dioxide concentration may be displayed.

Also, the air quality may be classified into a plurality of stages according to the deviation value or the like and displayed. In other words, in addition to arranging in order from the first place to the lowest place in order of deviation value (displaying in ranking format), "excellent, good, acceptable ...", "A, B, C ..." based on the deviation value. , etc., and may be displayed. In this way, it is possible to know whether the air quality of the target space (20) is in a desirable state or not (although the ranking is moderate, the air quality of the item of interest is good enough, etc.).

As a form of display, for example, classification may be displayed in place of (or in addition to) display of ranking in FIG. For individual items such as TVOC, the classification may be displayed by changing to specific numerical values.

Further, the providing unit (10) may provide the comparison information sorted by category with respect to the target space (20) and the other space (30).

As the target space (20) and the other space (30), various uses such as tenant buildings, hospitals, and schools can be considered. In addition, there are various regions (country, prefecture, climate classification, topography, etc.) in which the target space is located. Furthermore, there are various attributes of buildings such as building structures (steel frame construction, reinforced concrete construction, etc.) and building ages.

Such differences affect the air quality of the target space (20), and there are also differences in the desired air quality. Therefore, by sorting and providing the air quality information for the target space (20) by category such as usage, area, attribute, etc., it is possible to know comparative information by category. In addition, it is also possible to calculate a value within a category for a deviation value or the like. Here, categories may be combined.

For example, air quality information is sorted and provided in the form of air quality deviation values for tenant buildings in Tokyo, ranking of PM2.5 concentration in Kyushu, index classification based on temperature and humidity in schools in Hokkaido, etc. By doing so, it is possible to provide information that is more suitable for the purpose.

FIG. 3 shows another example of display in the providing section (10). In FIG. 3, the radar chart (11) shows the same item as in FIG. 2 for the indoor air quality of the target space (20) (broken line). In addition, in the same radar chart (11), the average value of each item in another space (30) is also shown (solid line). Such a representation can be used to more clearly indicate the cleanliness level of the target space (20) relative to other spaces (30).

In addition, FIG. 3 shows an image (12) symbolizing the air quality based on the values of each item of the detected indoor air quality. In the case of FIG. 3, since the air quality deviation value is 36 and the air quality is low, the image (12) symbolizing the low air quality is displayed. Depending on the specific air quality, for example, it may be a photograph of a factory generating dust or smoke, a road with heavy traffic, a crowd with a lot of dust, or the like. By displaying such an image (12), the air quality of the target space (20) can be grasped intuitively and sensuously.

Further, the indoor air quality providing device may provide improvement plans (13a, 13b, 13c) for improving the air quality of the target space (20) based on the air quality information of the target space (20).

At this time, a plurality of improvement proposals (13a, 13b, 13c) with different degrees of improvement may be provided. Also, the degree of improvement in air quality in the target space (20) when the improvement proposals (13a, 13b, 13c) are implemented may be predicted and provided.

In this way, the user can know the improvement plan of the air quality. In addition, it is possible to know and select a plurality of improvement plans according to the degree of improvement. Furthermore, it is possible to know the degree of improvement expected by implementing the improvement plan.

FIG. 4 illustrates the provision of improvement suggestions. In this example, three types of improvement proposals are shown regarding the improvement of the carbon dioxide concentration. The degree of improvement expected when each is implemented is also shown.

The first improvement plan (13a) proposes changing the seating arrangement and expects to improve the carbon dioxide concentration from 1500ppm to 1300ppm. A second improvement (13b) proposes installing a VAV (variable air volume) to control ventilation, which is expected to improve carbon dioxide levels from 1500 ppm to 1100 ppm. A third improvement plan (13c) proposes installing a total heat exchanger and expects to improve the carbon dioxide concentration from 1500 ppm to 800 ppm. For each improvement plan (13a, 13b, 13c), you may indicate the cost, delivery date, etc. together.

As shown in FIG. 4, on the screen displaying a plurality of improvement proposals (13a, 13b, 13c) side by side, any one of them may be selectable. Since the tablet (10) is used as the provision unit (10) here, the third improvement plan (13c) can be selected by tapping.

FIG. 5 shows an example of a transition display when the third improvement plan (13c) is selected. Although it is similar to the display in Fig. 3, the air quality deviation value, air quality ranking, etc. show the predictions when the third improvement plan (13c) is implemented. Radar chart (11) also shows the measured value of indoor air quality in the target space (20), the average value including the other space (30), and the expected value after the implementation of the improvement plan. . In addition, a photograph symbolizing the improved air quality is shown as an image (12a). For example, it may be a photograph of a forest, a clear stream, or the like.

Such a display allows the user to concretely and intuitively know the expected effect of implementing the proposed improvement.

An image showing the contents of the improvement proposal (for example, a total heat exchanger), the expected number of delivery days when an order is placed, the price, etc., may also be displayed.

Further, the apparatus for providing indoor air quality may include a receiver (14) that receives order information from a user for at least one of products and services for improving the air quality of the target space (20).

In FIG. 5, a purchase button (14) for the user to place an order for an improvement plan is displayed as the receiving section. Order information from the user is received by tapping the purchase button (14).

By doing so, the user can easily place an order for the product and/or service after confirming the expected effect of the improvement. Providers of products and/or services can expect an effect of prompting orders.

Further, the indoor air quality providing device may include a selection unit (15) that selects whether or not to disclose the air quality information of the target space (20) based on a user's instruction. As a result, the air quality information of the target space (20) can be made public at the request of the user.

This is illustrated in FIG. In FIG. 6, the air quality deviation value is 68, which is good, and the ranking is 126th among 2,365 cases, which is high. A selection section (15) for selecting whether or not to disclose such air quality information is displayed. When the user taps "Yes" in the selection part (15), information specifying the target space (20) (building name, etc.), specific air quality information (air quality deviation value, carbon dioxide concentration, etc.) items), etc. can be made public.

If the indoor air quality of the target space (20) is good, it is possible to advertise that the air quality of the office or the like is good, that the air quality control equipment is excellent, and the like. As a result, the value of the target space (20), such as a building, can be appealed and enhanced.

The user is, for example, a person who owns a building or the like including the target space (20) and installs an air conditioner for the target space (20). Such a user concludes a contract with a product and/or service provider (hereinafter referred to as "provider") and receives air quality information and the like. It is assumed that the owners of the space (30) elsewhere (other users) also have contracts with the respective providers.

Air quality information may be provided only to users who have entered into such agreements. In this case, mere building users who have not concluded a contract (for example, customers of a commercial building) do not see the air quality information. The user can see comparison information (average value, deviation value, ranking, etc.) with other spaces (30). In addition, when the air quality information of the space (30) elsewhere is open to the public (the user of the space has selected to be open to the public), the information can be viewed. Even if the user does not choose to publish the information, it will be used for comparison information such as rankings.

Users can also choose to release air quality information to the public (i.e., other than users who have contracted with the provider). In such a case, it is possible, for example, to appeal to the general public the excellent air quality.

<<Other embodiments>>
