DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environment control method for controlling an environment in accordance with a feeling such as comfort of a resident.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional comfortable environment design method performs a sensory report experiment by a subject, and obtains environmental measurement data such as temperature and humidity, and a sensory report data on the subject's thermal sensation and comfort. In this case, the design of the comfortable environment is controlled by performing a multiple regression analysis based on the data and obtaining a comfort evaluation index of the environment.

[0003] The physiological condition of human beings is a kind of black box, and the above-mentioned comfort evaluation index generally has a problem that it does not match the feelings of elderly people and infants. It is based on subject experiment data of people with sufficient physical strength such as university students).

Further, according to the conventional method, there is a problem that only a specific environment having correlation data between the environment and the sense can be evaluated.

[0005] For example, Japanese Patent Application Laid-Open No. 2-75846 discloses a technique for changing the indoor environment according to the frequency of brain waves. However, in this technique, in particular, in the control of the air conditioner, only the awake state and the sleep state of the human are determined, and the air conditioner is controlled so as to maintain the room temperature suitable for either state. In this case, it was not determined whether the maintained room temperature was suitable for the individual.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, an object of the present invention is to predict an individual's sense of human being in a certain environment, and to use the prediction data to estimate the surroundings of an air conditioner or the like. The purpose is to design a comfortable environment suitable for individuals by controlling the equipment.

[0007]

According to the environmental control method of the present invention, data relating to an external environment and data relating to personal characteristics are inputted, and a physiological quantity is determined from the data based on a mathematical model of body temperature regulation prepared in advance. Correlation between the obtained physiological quantity and pre-extracted sensation data for the external environment is used to predict the sensation, and the peripheral equipment for controlling the external environment is controlled based on the prediction of the sensation. I do.

[0008]

[Function] Calculates the physiological amount of an individual from the external environment by simulation using a mathematical model of body temperature regulation that can handle individual characteristics, and predicts the amount of individual sensation from data of physiological amount and sensation collected in subject experiments I do. This prediction is fed back to the design of the peripheral equipment, and the optimal environment is designed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A comfortable environment design method according to the present invention will be described below in detail with reference to one embodiment of the drawings.

FIG. 1 shows a conceptual diagram of an environment design which is the basis of the present invention. The present invention uses a comfort evaluation index that predicts comfort from environmental physical conditions such as room temperature, humidity, and air flow velocity with a view to realizing a comfortable environment, with a view to intervals such as occupant comfort. As shown in FIG. 1, the environment designed first is evaluated and examined using an individual's comfort evaluation index in 2 and the above-mentioned 1 is evaluated in 3 as shown in FIG. In this method, the amount of sense of an individual predicted from the environment is predicted, and the result is fed back to the design of the first environment to design the optimal environment for the individual.

The above two comfort evaluation indices are described in detail in FIG. 2 based on environmental conditions 4 such as temperature, humidity, airflow, and radiation in a certain environment.
Physiological parameters 6 such as body temperature, skin temperature, blood flow rate, perspiration rate, heat release rate, heat generation rate, heat storage rate, etc. under the environmental conditions were calculated by the simulation to which 5 was applied. This refers to performing a multiple regression analysis by correlating with a sensory (psychological) database 7, and by this analysis, an individual's sensory amount 8 such as warmth, coolness, comfort, and exhilaration is estimated. Although the obtained sensory quantity 8 is not shown, it is input to the control of the peripheral equipment for controlling the environmental condition 4.
Will be played back.

FIG. 3 is a block diagram showing an example in which the comfort environment design method shown in FIGS. 1 and 2 is applied to a comfort environment design support system. In the figure, fixed environment data 9 such as outside air temperature, outside air humidity, thickness and material of a wall material that separates the outside from the room, and variable environment data 10 such as an air conditioning system and a position of an air conditioner are keyed. Input from the board, the indoor environment simulation program 11 is started, and distribution data 12 such as indoor temperature and air flow is calculated. This distribution data 12 is input to a human body simulation program 14 based on a thermoregulation mathematical model, which will be described later, together with personal characteristics 13 such as age, gender, and degree of health. The data 15 converted to is calculated. Further, by applying the correlation between the physiological state data 15 and the database collected in advance in the subject's experiment to the comfort prediction model 16 having the correlation between the physiological quantity and the sensory quantity, the individual's sensation is predicted. Calculate quantity 17. The predicted amount 17 calculated in this manner corrects the variable environment data 10 so that the room created by the fixed environment data 9 and the variable environment data 10 becomes a comfortable environment for the individual. In order to do
Will be played back.

The mathematical model of thermoregulation used in the above embodiment is a mathematical model of the mechanism of thermoregulation of a human, for example, as shown in FIG. , The temperature of the external environment, the humidity, the airflow, the amount of activity, etc. when given variable amounts such as the body temperature, skin temperature, skin temperature,
This model is provided with physiological quantities such as calorific value, skin wetting rate, and skin blood flow as outputs.

[0014]

As described above, according to the present invention, a physiological quantity of an individual is calculated from data relating to the external environment and personal characteristics based on a mathematical model of body temperature regulation prepared in advance, and the physiological quantity obtained and extracted in advance. By predicting the amount of sensation corresponding to the external environment of the individual by correlating the data of the sensation with respect to the external environment and controlling peripheral equipment for controlling the external environment based on the prediction of the amount of sensation. Therefore, it is possible to control the peripheral equipment in consideration of not only the environmental conditions of the external world but also the characteristics of the individual's environment, thereby providing a comfortable environment. Further, since it is not necessary to measure the physiological amount in order to obtain the physiological amount of the individual, it is possible to eliminate the feeling of restraint and the trouble of performing the measurement due to the mounting of the measuring device, and it is possible to further improve the comfort.
