2. Description of the Related Art Conventionally, as an indoor air management device of this kind, a device used for the purpose of preventing a tobacco odor by using an odor detecting element or a gas detecting element selective to formaldehyde or VOC is used. , Those used as so-called sick house measures are known. However, although these detecting elements can detect the factors of the dirt of the air other than the person, they can know the degree of so-called human vibration that makes the person themselves uncomfortable by polluting the indoor air in their lives. Therefore, it was not possible to properly know the degree of discomfort in the room. Therefore, an indoor air management device using a carbon dioxide gas detection device, which is a main component of human vibration gas, has been proposed in order to detect gas generated by human vibration (hereinafter simply referred to as human vibration gas) and manage indoor air. .

As shown in FIG. 5, changes in the room temperature and humidity were not clearly distinguished by the experimental conditions.
It can be seen that the concentration of carbon dioxide gas and the concentration of hydrogen gas are clearly different depending on the experimental conditions and increase in proportion to the number of people and the activity time of people. This is because if there are no other factors,
It can be said that it can be evaluated based on the concentration of hydrogen gas. The hydrogen gas detection output changes well following the hydrogen gas concentration, and it can be seen that changes in hydrogen gas concentration and carbon dioxide gas concentration based on human activity are captured. Therefore, by monitoring the hydrogen gas detection output, it is possible to know the degree of human activity.

Without it, it will be possible to monitor people's activity easily and stably over a long period of time. In addition, since hydrogen gas is used as the gas to be detected, not carbon dioxide gas in human breathing gas, it can be monitored at a position above the room where it is not easily affected by turbulence of air flow due to daily life of a person. Compared with the air management device, it has become possible to accurately evaluate human activity without being affected by disturbance.

[Other Embodiment] Another embodiment will be described below. In the above-described embodiment, an example in which one hydrogen gas detection element is provided in the room to be managed has been shown, but if the room to be managed is large, a plurality of hydrogen gas detection elements are provided to reduce the bias in the indoor environment. It can be used in the form of operating an air conditioner to correct it. If it is considered that the concentration of hydrogen gas in the room is affected by the exhaust gas entering from the outside, the difference in output between the hydrogen gas detection element outside the room and the hydrogen gas detection element inside the room will cause a difference in human activity. Can be evaluated. By doing so, it is possible to reduce the influence of hydrogen gas generated by factors other than human motion and evaluate human motion.
