Therefore, when the display method and the display device U of the environmental comfort provided by the present invention are applied in an indoor environment (such as an exhibition hall or a shopping mall), the current comfort level in the exhibition hall or a shopping mall can be known.

Following the above, please refer to FIG. 6 again, and refer to FIG. 7 together. FIG. 7 is a flowchart of step S102 of the method for displaying environmental comfort according to the second embodiment of the present invention. Further, as shown in step S1022, carbon dioxide gas concentration information is obtained through a gas concentration information sensing module, temperature information is obtained through a temperature sensing module, and relative humidity is obtained through a humidity sensing module News. For example, the gas concentration information sensing module 2 in the display device U for environmental comfort provided by the foregoing embodiment may be used to obtain a carbon dioxide gas concentration information, and send the carbon dioxide gas concentration information to the control module 1, while Then, the control module 1 is used to convert the carbon dioxide gas concentration information into a gas concentration index.

At the same time, the temperature information and relative humidity information are sent to the control module 1, and then the control module 1 is used to convert the temperature information and relative humidity information into a temperature and humidity index.

Following the above, please refer to FIG. 7 again. As shown in step S1024, the temperature and humidity index formula is calculated by using the Celsius temperature information and the relative humidity information to calculate the temperature and humidity index, and the carbon dioxide gas concentration information is used to obtain the gas concentration index. For the purposes of the present invention, the temperature and humidity index formula conforms to the following relationship: (1.8×T+32)-(0.55-0.0055×RH)×(1.8×T-26), where T is temperature information in Celsius and RH is relative Humidity information. In addition, according to the present invention, the calculation method of the gas concentration index can meet the following relationship: GCI=CCI/30, where GCI is the gas concentration index and CCI is the carbon dioxide gas concentration information. In this way, when the carbon dioxide gas concentration is 3000 ppm, the gas concentration index is 100, when the carbon dioxide gas concentration is 0 ppm, the gas concentration index is 0, when the carbon dioxide gas concentration is 1000 ppm, the gas concentration index is about 33.3, when the carbon dioxide gas concentration At 1800 ppm, the gas concentration index is approximately 60.

Next, please refer to FIG. 6 again. As shown in step S104, an environmental comfort index is obtained according to the gas concentration index and the temperature and humidity index. For example, an environmental comfort index calculation formula of the environmental comfort index conforms to the following relationship: SEI=GCI+(THI-THTH); where SEI is the Environmental Comfort Index (Suitable Environmental Index) and GCI is the gas concentration Index (Gas Concentration Index), THI is Temperature Humidity Index (Temperature Humidity Index), THTH is a preset temperature and humidity index threshold (Temperature Humidity Index Threshold). Further, the preset temperature and humidity index threshold value may be a value generated when the human body feels uncomfortable. For example, the preset temperature and humidity index threshold value is between 70 and 78. Set the value of the temperature and humidity index threshold to 74. However, in other embodiments, the preset temperature and humidity index threshold value is 72. In this way, the control module 1 provided in the foregoing embodiment can be used, According to the above method, the environmental comfort index can be calculated. In addition, it should be noted that since the temperature, humidity and/or carbon dioxide concentration in the environment will vary with the number of people in the indoor area or the environment, the environmental comfort index will also change accordingly. Further, when the preset temperature and humidity index threshold value is below 74, the human body feels comfortable. When the preset temperature and humidity index threshold value is between 75 and 79, the human body feels a little uncomfortable but still within the acceptance range, the preset temperature When the humidity index threshold is above 80, the human body feels extremely uncomfortable. However, it should be noted that the present invention is not limited to this.

FIG. 8 is a flowchart of step S106 of the method for displaying environmental comfort according to the second embodiment of the present invention. One is the correspondence table between the environmental comfort index and color information. As shown in step S1062, it is determined whether the numerical value of the environmental comfort index is one of a plurality of numerical intervals. In addition, as shown in step S1064, the color information corresponding to one of the numerical value intervals is displayed.

Further, since the value of the environmental comfort index changes with temperature, humidity, and/or carbon dioxide concentration, color information of different colors can be generated according to different values of the environmental comfort index. In other words, multiple numeric intervals and multiple color information corresponding to different numeric intervals can be provided, and then, the display module 5 displays the color information corresponding to one of the numeric intervals corresponding to the values of the environmental comfort index . Further, the plurality of numerical intervals may be continuous intervals, and each numerical interval has its corresponding color information.

Following the above, please refer to FIG. 6, FIG. 8 and Table 1 below. Further, the plurality of value intervals may include at least a first value interval and a second value interval, and the first value interval and the second value The intervals are different from each other. Thus, in step S106, the environmental comfort index can be judged first The value is in a first value interval or a second value interval. Then, when the value of the environmental comfort index is located in the first numerical interval, the color information corresponding to the first numerical interval is displayed, and when the value of the environmental comfort index is located in the second numerical interval, the display corresponds to the second numerical interval Color information. In addition, in order to distinguish the meaning represented by the first numeric interval and the second numeric interval, the color information corresponding to the first numeric interval is different from the color information corresponding to the second numeric interval. Further, the color information corresponding to the first numerical interval may be the first color, the color information corresponding to the second numerical interval may be the second color, and the first color and the second color are different from each other. In this way, people can use the color information displayed by the environmental comfort display device U to understand the current level of comfort in the exhibition hall or shopping mall.

Then, please refer to the following table 1 again. For example, when the value of the environmental comfort index is between 0 and 10, the value representing the environmental comfort index is located in the first numerical range; When it is between 11 and 20, the value representing the environmental comfort index is in the second numerical range; when the value of the environmental comfort index is between 21 and 30, the value representing the environmental comfort index is in the third numerical range; When the value of the comfort index is between 31 and 40, the value representing the environmental comfort index is in the fourth numerical range; when the value of the environmental comfort index is between 41 and 60, the value representing the environmental comfort index is Fifth numerical range; when the value of the environmental comfort index is between 61 and 100, the value representing the environmental comfort index is located in the sixth numerical range. In addition, for example, the first color may be green, the second color may be yellow, the third color may be orange, the fourth color may be red, the fifth color may be purple, and the sixth color may be reddish brown, However, the invention is not limited to this. In addition, for example, the color information corresponding to the first numerical interval may be the first color, the color information corresponding to the second numerical interval may be the second color, and the color information corresponding to the third numerical interval may be the third color The color information corresponding to the fourth numerical interval may be the fourth color, the color information corresponding to the fifth numerical interval may be the fifth color, and the color information corresponding to the sixth numerical interval may be the sixth color. In addition, when the value of the environmental comfort index is at the sixth value In the interval, it means that the human body will feel extremely uncomfortable. Therefore, the display module 5 may display the sixth color at the same time, and may blink the color of the sixth color with the light on and off, but the invention is not limited thereto.

In this way, the color information corresponding to the numerical interval can be generated according to the numerical interval corresponding to the value of the environmental comfort index. However, it should be noted that the color information corresponding to the value of the environmental comfort index is only an example, and in other implementations, the range of the value of the environmental comfort index is not limited to 6 numerical intervals. It is also possible to adjust the number of numerical ranges and the number and color of the corresponding color information according to requirements. In this way, people can use the color information displayed by the environmental comfort display device U to understand the current level of comfort in the exhibition hall or shopping mall. In addition, other users who are not located near the exhibition hall or shopping mall can also use the electronic device P to query the current level of comfort in the exhibition hall or shopping mall, and then decide whether to go there.
