Problems solved by technology

Therefore, even if the air quality of the outside air is worse than the air quality of the space of interest, ventilation may be performed. In this case, although the air quality is improved, the air quality of the space of interest may decrease.

Embodiment approach 1

[0053] Hereinafter, the embodiment will be described in further detail. The implementation described below assumes that figure 1 The energy management system of the structure shown. The energy management system includes an environment management device 10 having a function of instructing operation of each of a plurality of environment improving devices 301 and 302 , and a measuring device 20 which measures electric power used by the environment improving devices 301 and 302 .

[0054] Any environmental improvement devices 301 and 302 used by consumers can be controlled by the environmental management apparatus 10 as long as they are controlled objects. However, in the following description, the environment improvement devices 301 and 302 for improving indoor air quality (IAQ: Indoor Air Quality) will be described as control objects. Air quality is related to the quality of air for people to live in a healthy and comfortable way, and targets various environmental factors. En...

Embodiment approach 2

[0104] In Embodiment 1, the operation when the evaluation unit 16 compares the measurement data obtained from the air quality sensor 21 by the air quality acquisition unit 13 with the good or bad reference value and evaluates it as bad is mainly described. The operation when the evaluation is not bad will be described.

[0105] Environmental factors that determine good or bad air quality include volatile organic compounds. Formaldehyde, which is widely used in adhesives and building materials, can be cited as a representative example of such volatile organic compounds. Volatile organic compounds as environmental factors Various volatile organic compounds are known besides formaldehyde, and it cannot be said that it is a good idea to configure the air quality sensor 21 to measure the concentration of volatile organic compounds.

[0106] On the other hand, it is known that the release amount of formaldehyde increases when the temperature becomes about 25° C., and that the relea...

Embodiment approach 3

[0114] In this embodiment, similar to the second embodiment, the operation when the evaluation unit 16 compares the measurement data acquired by the air quality acquisition unit 13 from the air quality sensor 21 with a good / failure reference value and evaluates that it is not defective will be described. Among them, in the second embodiment, attention is paid to volatile organic compounds among the environmental factors that determine whether the air quality is good or not. However, this embodiment describes a technology that mainly focuses on viruses as environmental factors.

[0115] It is generally believed that the virus is active for a long time when the indoor humidity (relative humidity) is lowered. For influenza virus, it is generally believed that when the humidity exceeds 40% to 50%, it will be inactivated in a short time, but when the humidity is lower than 40%, its activity will not weaken for a long time.

[0116] Therefore, the present embodiment focuses on the i...

Abstract

The invention disclsoes an environment management device (10), which is used to control motion statuses of a ventilation device (31) used for the indoor-outdoor ventilation to change the indoor air quality, an air purifier (32) and an air conditioner (33)used for improving the indoor air quality without the ventilation. The environment management device (10) is provided with an air quality acquisition part (13), an indication part (14), a management processing part (15), and an evaluation part (16). The air quality acquisition part (13) can be used to acquire the indoor and outdoor air quality measurement data from an air quality sensor (21). When the management processing part (15) rates the indoor quality as adverse, when the outdoor air quality is better than the indoor air quality, the ventilation device (31) can be started, and when the indoor air quality is better than the outdoor air quality, at least one of the air purifier (32) and the air conditioner (33) is started.

Description

technical field [0001] The present invention relates to an environment management device for managing the operating state of an environment improvement device for improving indoor air quality. Background technique [0002] Conventionally, there has been proposed a technique for improving indoor air quality by managing the operating state of an environment-improving device (see, for example, Japanese Patent Laid-Open No. 2010-255900). The above-mentioned document describes a technique in which the indoor air quality is detected by an environment monitoring device, and the operating states of air-conditioning equipment and ventilating equipment are controlled. In addition, the above-mentioned document describes the control of ventilation equipment as follows: in order to remove carbon dioxide, carbon monoxide, formaldehyde, etc. The air quality becomes the set air quality. [0003] The environment monitoring device described in the above document monitors the air quality of ...
