Description

Air management device, air management method, program, and computer-readable storage medium

[0001] The present invention relates to an air management device, an air management method, a program, and a computer-readable storage medium, and more particularly to an air management device, an air management method, a program, and a computer-readable storage medium that can appropriately manage air.

[0002] The commonly accepted airborne measurement parameters are temperature and humidity. This is because temperature and humidity are important factors that affect the physical sensation. Other measurement parameters for monitoring air pollution include carbon dioxide, nitrogen oxides, sulfur oxides, and PM2.5. A typical indicator of indoor pollution is the measurement of VOCs (volatile organic compounds: allergens that cause sick house syndrome) (see, for example, Patent Document 1). Furthermore, in clean rooms where semiconductors, pharmaceuticals, etc. are manufactured, continuous measurement equipment for fine particles is installed to monitor the level of pollution. The entire specification, claims, and drawings of Patent Document 1 are incorporated herein by reference.

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2003-279449

[0004] As mentioned above, there are various indicators for measuring air pollution, and the measurement methods vary depending on the indicator. This makes it impossible to measure air pollution in a unified manner, and therefore it has been difficult to manage air appropriately.

[0005] The present invention has been made to solve the above-mentioned problems, and aims to provide an air management device, an air management method, a program, and a computer-readable storage medium that can appropriately manage air.

[0006] In order to achieve the above object, an air management device (1) according to a first aspect of the present invention comprises a collection unit (2) that collects moisture in the air, a potential measurement unit (3) that measures the oxidation-reduction potential of the moisture in the air collected by the collection unit (2), and a control unit (6) that outputs information about pollution of the air based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit (3).

[0007] The air management device (1) may be configured such that the control unit (6) determines whether the air is polluted or not based on whether the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit (3) is equal to or greater than a predetermined threshold value, and outputs information regarding the pollution of the air.

[0008] The air management device (1) may further include a reduction section (4) that reduces the moisture in the air collected by the collection section (2) to lower the redox potential of the moisture in the air, and when the control section (6) determines that the redox potential of the moisture in the air is equal to or higher than a predetermined threshold and the air is contaminated, the control section (6) may reduce the moisture in the air collected by the collection section (2) in the reduction section (4) to lower the redox potential of the moisture in the air to below the predetermined threshold, thereby removing contaminants from the moisture in the air.

[0009] The air management device (1) may further include a diffusion section (5) that re-diffuses the moisture in the air collected by the collection section (2) into the air, and when the control section (6) determines that the redox potential of the moisture in the air is equal to or greater than a predetermined threshold and that the air is polluted, the control section (6) may reduce the moisture in the air collected by the collection section (2) in the reduction section (4) to remove contaminants, and then re-diffuse the moisture in the air from the diffusion section (5) into the air, and when the control section (6) determines that the redox potential of the moisture in the air is less than the predetermined threshold and that the air is not polluted, the control section (6) may re-diffuse the moisture in the air collected by the collection section (2) into the air as is from the diffusion section (5).

[0010] The air management device (1) may have a temperature setting unit (7) that sets a first temperature, which is a relatively high temperature, and a second temperature, which is a relatively low temperature, and an air temperature measuring unit (8) that measures the temperature of the air, and the control unit (6) may be configured to perform a first control in which, when the oxidation-reduction potential of the moisture in the air is equal to or higher than a predetermined threshold and the temperature of the air measured by the air temperature measuring unit (8) is equal to or higher than the first temperature set by the temperature setting unit (7), the control unit (6) reduces the moisture in the air recovered by the recovery unit (2) in the reduction unit (4) to reduce the oxidation-reduction potential of the moisture in the air to below the predetermined threshold and reduce the temperature of the air to the first temperature as a lower limit.

[0011] The air management device (1) has a temperature setting unit (8) that sets a first temperature that is a relatively high temperature and a second temperature that is a relatively low temperature, and an air temperature measuring unit (7) that measures the temperature of the air, and the control unit (6) may be configured to, when the redox potential of the moisture in the air is less than the predetermined threshold and the temperature of the air measured by the air temperature measuring unit (7) is equal to or less than the second temperature set by the temperature setting unit (8), oxidize the moisture in the air recovered by the recovery unit (2) in the oxidation unit (9) to increase the redox potential of the moisture in the air to equal to or greater than the predetermined threshold and perform second control to increase the temperature of the air up to the second temperature as an upper limit.

[0012] In the air management device (1), the control unit (6) may be configured to, in the first control, control the amount of re-dissipation by the dissipation unit (5) to be less than the amount of moisture in the air collected by the collection unit (2), thereby reducing the humidity of the air.

[0013] In the air management device (1), the control unit (6) may be configured to control the amount of re-emission by the emission unit (5) in the second control so that it is greater than the amount of moisture in the air recovered by the recovery unit (2), thereby increasing the humidity of the air.

[0014] An air management method according to a second aspect of the present invention is characterized in that a collection unit (2) collects moisture in the air, a potential measurement unit (3) measures the oxidation-reduction potential of the moisture in the air collected by the collection unit (2), and a control unit (6) outputs information about pollution of the air based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit (3).

[0015] A program according to a third aspect of the present invention causes a computer to execute the steps of collecting moisture in the air, measuring the oxidation-reduction potential of the collected moisture in the air, and outputting information about pollution of the air based on the measured oxidation-reduction potential of the moisture in the air.

[0016] A computer-readable storage medium according to a fourth aspect of the present invention is for storing the above-described program.

[0017] According to the present invention, it is possible to provide an air management device, an air management method, a program, and a computer-readable storage medium that can appropriately manage air.

[0019] The best mode for carrying out the present invention will now be described.

[0020] First, the configuration of an air management device according to an embodiment of the present invention will be described with reference to the drawings.

[0021] Measurement of airborne pollutants is generally performed by aspirating the air, adsorbing the pollutants onto a filter or capturing them in a liquid, and then using a chemical analyzer, sensor, or the like. In other words, not only the air itself but also the moisture in the air is used to measure airborne pollutants. Here, the components of air are approximately 78% nitrogen, approximately 21% oxygen, and approximately 1% carbon dioxide, which are virtually the same no matter where on Earth they are measured. Therefore, airborne pollutants are not contained as a component of the air, but are contained in the moisture in the air.

[0022] Considering that most pollutants in the air are chemically oxides or oxidizers, moisture containing pollutants increases the oxygen reduction potential (ORP). Therefore, the air management device according to this embodiment is designed to determine whether air is polluted based on the moisture content of the air in a substantially enclosed space such as a room or facility (hereinafter, "air" refers to air in a substantially enclosed space such as a room or facility). As is clear from the above and below, in this embodiment, air being polluted refers to a state in which the moisture in the air contains substances that affect the redox potential, such as oxides or oxidizers, and oxides and oxidizers are considered to be the main pollutants.

[0023] FIG. 1 is a diagram showing an example of the configuration of an air management device according to this embodiment.

[0024] As shown in FIG. 1 , the air management device 1 includes a recovery unit 2 , a potential measurement unit 3 , a reduction unit 4 , a diffusion unit 5 , and a control unit 6 .

[0025] The collection unit 2 is configured by, for example, a general-purpose dehumidifier, etc. Under the control of the control unit 6, the collection unit 2 dehumidifies a substantially closed space such as a room or the inside of a facility, and continuously collects moisture from the air.

[0026] The potential measurement unit 3 is composed of, for example, an ORP sensor used in monitoring acid rain. Under the control of the control unit 6, the potential measurement unit 3 continuously measures the ORP of the moisture in the air collected by the collection unit 2. The air management device 1 may also include an output unit that displays or prints out the ORP measured by the potential measurement unit 3. The output unit may include a display device having a display screen such as a liquid crystal display, or a printer that can output printed materials.

[0027] The reduction unit 4 is composed of a general-purpose reduced water generator that reduces water by, for example, electrolysis or using reducing ceramics, etc. Under the control of the control unit 6, the reduction unit 4 reduces the moisture in contaminated air and reduces the ORP of the moisture in the air, thereby removing contaminants from the moisture.

[0028] The dissipation unit 5 is configured by, for example, a general-purpose humidifier, etc. Under the control of the control unit 6, the dissipation unit 5 dissipates the moisture collected by the collection unit 2 back into the air to humidify it.

[0029] The control unit 6 is composed of a processor or the like including, for example, a CPU (Central Processing Unit), a memory (memory, more specifically, a ROM (Read Only Memory) and a RAM (Random Access Memory)), etc. The CPU uses the RAM as work memory and controls various operations of the air management device 1 by appropriately executing various programs, etc. stored in the ROM.

[0030] In this embodiment, the control unit 6 outputs information about air pollution based on the oxidation-reduction potential of moisture in the air measured by the potential measurement unit 3. More specifically, the control unit 6 determines whether the moisture in the air is polluted, i.e., whether the air is polluted, based on whether the ORP measured by the potential measurement unit 3 is equal to or greater than a predetermined threshold. If the ORP measured by the potential measurement unit 3 is equal to or greater than the predetermined threshold, the control unit 6 determines that the moisture in the air is polluted and that the air is also polluted, and outputs information about air pollution. If the ORP measured by the potential measurement unit 3 is less than the predetermined threshold, the control unit 6 determines that the moisture in the air is not polluted and that the air is not polluted.

[0031] More specifically, if the ORP measured by the potential measuring unit 3 is equal to or greater than a predetermined threshold, the control unit 6 determines that the moisture in the air is contaminated and that the air is also contaminated, and outputs information to the effect that the air is contaminated (information about air pollution); if the ORP is less than the predetermined threshold, the control unit 6 determines that the moisture in the air is not contaminated and that the air is not contaminated, and outputs information to the effect that the air is not contaminated.

[0032] More specifically, if the ORP measured by the potential measurement unit 3 is equal to or higher than a predetermined threshold, the control unit 6 determines that the moisture in the air is polluted and the air is also polluted, and can output a pollution level of the air indicated in accordance with the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3 (the pollution level of the air is included in the information on air pollution and information on whether the air is polluted). The control unit 6 outputs the pollution level of the air to the output unit described above, and can display or print the pollution level of the air via the output unit. The control unit 6 stores data or a formula indicating the correlation between the oxidation-reduction potential of the moisture in the air and the pollution level of the air in MEMORY. The control unit 6 can calculate and output the pollution level corresponding to the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3 based on the data or a formula indicating the correlation between the oxidation-reduction potential of the moisture in the air and the pollution level stored in MEMORY. For example, when the oxidation-reduction potential of moisture in the air is equal to or greater than a predetermined threshold, the smaller the difference Δα between the oxidation-reduction potential A of moisture in the air measured by the potential measuring unit 3 and the bioelectric potential B (threshold) shown in equation 1, the lower the level of air pollution, and the larger the difference Δα, the higher the level of air pollution. MEMORY stores data or a formula showing the correlation between Δα shown in equation 1 and the level of air pollution. [Equation 1] Δα=A-B

[0033] Here, the predetermined threshold value may be set in advance depending on the intended use of the air management device 1 .

[0034] Specifically, when used to create an optimal living environment for animals (mammals), including humans, the ORP (skin potential) of animal skin of approximately 100 mv to 200 mv is the optimal ORP (hereinafter referred to as "biopotential") for animals, so the predetermined threshold can be set to 200 mv. When used to create an optimal living environment for plants, the biopotential of plants is approximately 0 mv to 100 mv, so the predetermined threshold can be set to 100 mv. When used to create an optimal living environment for microorganisms, such as fungi (e.g., mold and yeast), bacteria, and viruses, the biopotential of microorganisms is approximately 200 mv to 400 mv, so the predetermined threshold can be set to 400 mv. When used to prevent food spoilage and maintain freshness, the predetermined threshold can be set to 0 mv.

[0035] When the control unit 6 determines that the air is contaminated, it reduces the moisture in the air collected by the collection unit 2, i.e., the contaminated moisture, in the reduction unit 4, thereby lowering the ORP of the moisture to below a predetermined threshold, thereby removing contaminants from the moisture. The control unit 6 then re-diffuses the moisture from which the contaminants have been removed into the air in the substantially closed space from the diffusion unit 5. On the other hand, when the control unit 6 determines that the air is not contaminated, it re-diffuses the moisture in the air collected by the collection unit 2, i.e., the uncontaminated moisture, directly into the air in the substantially closed space from the diffusion unit 5. In this way, the control unit 6 removes contaminants from the air collected by the collection unit 2 while removing contaminants from the contaminated moisture and then re-diffusing it into the air in the substantially closed space, thereby maintaining a constant humidity level in the air while removing contaminants from the air. Furthermore, the control unit 6 reduces the ORP of the moisture in the air to below a predetermined threshold set for each organism, thereby enabling organisms to live separately, activating each organism, and allowing them to demonstrate their inherent vitality.

[0036] Next, the air management process executed by the air management device having the above configuration will be described with reference to the drawings.

[0037] FIG. 2 is a flowchart showing the details of the air management process.

[0038] 2, first, the collection unit 2 of the air management device 1 dehumidifies the substantially closed space and continuously collects moisture from the air (step S201) under the control of the control unit 6. In other words, the control unit 6 causes the collection unit 2 to dehumidify the substantially closed space and continuously collect moisture from the air.

[0039] Next, under the control of the control unit 6, the potential measurement unit 3 continuously measures the ORP of the moisture in the air collected by the collection unit 2 in step S201 (step S202). In other words, the control unit 6 causes the potential measurement unit 3 to continuously measure the ORP of the moisture in the air collected by the collection unit 2.

[0040] The control unit 6 then determines whether the moisture in the air is polluted, i.e., whether the air itself is polluted, based on whether the ORP measured by the potential measurement unit 3 is equal to or greater than a predetermined threshold, and further outputs information regarding air pollution (information indicating that the air is polluted, information indicating that the air is not polluted) (step S203). More specifically, if the ORP measured by the potential measurement unit 3 is equal to or greater than a predetermined threshold, the control unit 6 determines that the moisture in the air is polluted and that the air is also polluted, calculates the air pollution level indicated by the oxidation-reduction potential of the air measured by the potential measurement unit 3, and outputs the air pollution level to the output unit (the air pollution level is, for example, level 1, 2, ..., pollution level 100%, 90%, ..., pollution level strong, medium, weak, ...).

[0041] If the control unit 6 determines that the air is contaminated (step S203; Yes), the control unit 6 reduces the moisture in the air collected by the collection unit 2, i.e., the contaminated moisture, in the reduction unit 4 to reduce the ORP of the moisture to below a predetermined threshold, thereby removing contaminants from the moisture (step S204).The control unit 6 then re-diffuses the moisture from which the contaminants have been removed into the air in the substantially closed space from the diffusion unit 5 (step S205), and terminates the air management process.

[0042] On the other hand, if the control unit 6 determines that the air is not contaminated (step S203; No), it skips step S204 and re-dissipates the moisture in the air collected by the collection unit 2, i.e., the uncontaminated moisture, directly from the dissipation unit 5 into the air in the approximately closed space (step S205), and then terminates the air management process.

[0043] As described above, the air management device 1 according to this embodiment includes a collection unit 2 that collects moisture in the air, a potential measurement unit 3 that measures the oxidation-reduction potential of the moisture in the air collected by the collection unit 2, and a control unit 6 that outputs information about air pollution based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3. In this way, by measuring the oxidation-reduction potential of the moisture in the air, the air management device 1 according to this embodiment can easily and appropriately determine whether the air is polluted and can appropriately manage the air.

[0044] Furthermore, in the air management device 1, the control unit 6 determines whether the air is polluted based on whether the oxidation-reduction potential of moisture in the air measured by the potential measurement unit 3 is equal to or greater than a predetermined threshold, and outputs information regarding air pollution. This allows the air management device 1 according to this embodiment to manage the air appropriately.

[0045] Furthermore, the air management device 1 further includes a reduction unit 4 that reduces the moisture in the air collected by the collection unit 2, thereby lowering the redox potential of the moisture in the air. When the control unit 6 determines that the redox potential of the moisture in the air is equal to or greater than a predetermined threshold and that the air is polluted, the control unit 6 reduces the moisture in the air collected by the collection unit 2 in the reduction unit 4, thereby lowering the redox potential of the moisture in the air to below the predetermined threshold, thereby removing contaminants from the moisture in the air. This allows the air management device 1 of this embodiment to remove air contaminants and appropriately manage the air. Setting the predetermined threshold according to the purpose can achieve various effects, such as changes in bodily sensations, healthier plants, and the ability to coexist with microorganisms.

[0046] For example, even if a person is in a room in an urban area and on a bench near a waterfall in a forest, with temperatures of approximately 30°C and humidity levels of approximately 60%, the bench near the waterfall in the forest feels cool and comfortable, while the person sweats profusely in the room in the city, resulting in a significant difference in physical sensation. Therefore, when the ORP of moisture in the air was measured, the ORP on the bench near the waterfall in the forest was 198 mV, which is below the predetermined threshold (200 mV), while the ORP in the room in the city was 398 mV, which is above the predetermined threshold. In other words, if the ORP of moisture in the air is approximately the same as the human skin potential (approximately 100 mV to 200 mV), the person will feel comfortable and be able to experience the natural physical sensation. Therefore, by using the air management device 1 according to this embodiment to keep the ORP of moisture in the air in urban rooms below a predetermined threshold and roughly match the human skin potential, people's perceived temperature is normalized, and they can feel comfortable and experience the same natural temperature indoors in the city as they would on a bench near a waterfall in the forest. This allows people to feel comfortable and experience the natural temperature even indoors in the city, even if the air conditioner setting is around 33°C, which is slightly lower than body temperature. This is expected to significantly improve the current global energy situation (electricity, CO2 emissions, etc.), and to have enormous environmental and economic benefits.

[0047] Furthermore, an environment in which the ORP of moisture in the air is much higher than the skin potential of a normal person is a highly oxidizing environment (an environment with a high level of air pollution) that causes hyperoxidation in humans. Humans and oxidation are closely related; without oxidation, the body would be unable to take in oxygen and would be unable to absorb and break down nutrients, making it impossible to survive. Hyperoxidation can also cause various diseases. Therefore, by using the air management device 1 according to this embodiment to roughly match the ORP of moisture in the air with the skin potential of a normal person (approximately 100 mV to 200 mV), it is possible to expect relief from the symptoms of various diseases.

[0048] Furthermore, in the case of plants, by using the air management device 1 of this embodiment in a substantially closed space such as a greenhouse, the ORP of the moisture in the air in the substantially closed space can be made to approximately match the bioelectric potential of the plant (approximately 0 mV to 100 mV), which normalizes the plant's inherent ability to repel pests and diseases, allowing the plant to demonstrate its natural growth potential, bringing out its flavor, and reducing the use of harmful pesticides and chemical fertilizers, ultimately reducing environmental destruction.

[0049] Furthermore, in the case of microorganisms, by using the air management device 1 according to the present embodiment, in which a predetermined threshold is set to the bioelectric potential of microorganisms (approximately 200 mV to 400 mV) in a substantially closed space, and by making the ORP of the moisture in the air in the substantially closed space approximately equal to the bioelectric potential of plants, it is possible to grow beneficial microorganisms such as yeast and lactic acid bacteria, and increase the fermentation efficiency of the production of sake, miso, and other fermented foods. Conversely, by using the air management device 1 according to the present embodiment, in which a predetermined threshold is set to less than the bioelectric potential of plants, the ORP of the moisture in the air in a substantially closed space such as a room or a building such as a hospital or school can be made less than the bioelectric potential of plants, thereby suppressing the growth of harmful microorganisms such as the novel coronavirus, preventing infection, and ultimately preventing a pandemic.

[0050] In the case of food products, by using the air management device 1 of this embodiment in an approximately closed space such as a transport warehouse (container, transport vehicle loading platform), the ORP of the moisture in the air in the approximately closed space can be set to a negative potential of less than 0 mV, thereby preventing spoilage (oxidation) of food products (meat, fish, vegetables, fruit) even when transported at room temperature.

[0051] Furthermore, the air management device 1 further includes a diffusion unit 5 that re-diffuses into the air the moisture in the air collected by the collection unit 2. When the control unit 6 determines that the redox potential of the moisture in the air is equal to or greater than a predetermined threshold and that the air is polluted, the control unit 6 reduces the moisture in the air collected by the collection unit 2 in the reduction unit 4 to remove the contaminants, and then re-diffuses the moisture into the air from the diffusion unit 5. On the other hand, when the control unit 6 determines that the redox potential of the moisture in the air is less than the predetermined threshold and that the air is not polluted, the control unit 6 re-diffuses into the air the moisture in the air collected by the collection unit 2 as is from the diffusion unit 5.

[0052] In this way, the control unit 6 leaves uncontaminated moisture in the air collected by the collection unit 2 as is, and removes dirt from contaminated moisture before dispersing it back into the air within the approximately closed space, thereby maintaining a constant humidity level in the air while removing dirt from the air and allowing the air to be managed appropriately.

[0053] The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Modifications of the above-described embodiment that can be applied to the present invention will be described below.

[0054] The air management device 1 according to the above embodiment can achieve the effects of changing the perceived temperature and inhibiting microbial growth as described above, as well as maintaining food freshness and preventing aging. Therefore, in addition to using the air management device 1 on its own, it can also be incorporated as a module into beauty-related devices such as air conditioners, air purifiers, refrigerators, freezers, diffusers, facial massagers, and cooling slimming machines, and can be operated in conjunction with these devices to achieve various synergistic effects.

[0055] In the above embodiment, the program executed by the CPU of the control unit 6 is described as being stored in advance in a ROM or the like, but the present invention is not limited to this, and the program for executing the above-mentioned processing may be applied to an existing general-purpose computer to function as the air management device according to the above embodiment.

[0056] Such a program may be provided in any manner, and may be distributed by storing it on a computer-readable recording medium (such as a flexible disk, a CD (Compact Disc)-ROM, or a DVD (Digital Versatile Disc)-ROM), or may be provided by storing the program in storage on a network such as the Internet and downloading it.

[0057] Furthermore, when the above processing is performed by sharing the work between an OS (Operating System) and an application program, or by cooperation between the OS and the application program, only the application program may be stored on a recording medium or storage. It is also possible to superimpose the program on a carrier wave and distribute it over a network. For example, the program may be posted on a bulletin board system (BBS) on a network and distributed over the network. The above processing may then be performed by starting up this program and running it under the control of the OS in the same way as other application programs.

[0058] Furthermore, in the above-described embodiment, the control unit 6 of the air management device 1 determines whether the air is polluted based on whether the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3 is equal to or greater than a predetermined threshold, and outputs information regarding the air pollution. However, the control unit 6 may output information regarding the air pollution simply based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3, without determining whether the oxidation-reduction potential is equal to or greater than the threshold. Furthermore, if the oxidation-reduction potential is less than the predetermined threshold, the control unit 6 determines that the moisture in the air is not polluted and the air is not polluted, and outputs information indicating that the air is not polluted. However, the control unit 6 may also calculate the air pollution level (e.g., pollution level 0%, no pollution level, etc.) as information indicating that the air is not polluted, and output this information to the output unit.

[0059] Furthermore, as shown in FIG. 3, a temperature setting unit 7, an air temperature measuring unit 8, and an oxidation unit 9 may be added to the air management device 1 of the above-described embodiment.

[0060] That is, the air management device 1 shown in FIG. 3 also includes a collection unit 2 that collects moisture in the air, a potential measurement unit 3 that measures the oxidation-reduction potential of the moisture in the air collected by the collection unit 2, and a control unit 6 that outputs information about air pollution based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3, and the control unit 6 determines whether the air is polluted or not based on whether the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3 is equal to or higher than a predetermined threshold and outputs information about air pollution, and further includes a reduction unit 4 that reduces the moisture in the air collected by the collection unit 2 to lower the oxidation-reduction potential of the moisture in the air, and the control unit 6 determines whether the air is polluted or not based on whether the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3 is equal to or higher than a predetermined threshold and outputs information about air pollution. The air conditioner further includes a diffusion unit 5 that reduces the moisture in the air collected by the collection unit 2 in a reduction unit 4, thereby reducing the oxidation-reduction potential of the moisture in the air to below a predetermined threshold, thereby removing contaminants from the moisture in the air, and re-diffuses the moisture in the air collected by the collection unit 2 back into the air when it is determined that the oxidation-reduction potential of the moisture in the air is equal to or higher than the predetermined threshold and the air is contaminated, and then re-diffuses the moisture in the air collected by the collection unit 2 from the diffusion unit 5 back into the air when it is determined that the oxidation-reduction potential of the moisture in the air is equal to or higher than the predetermined threshold and the air is not contaminated;

[0061] As mentioned above, air pollution refers to a state in which the moisture in the air contains substances that affect the redox potential, such as oxides and oxidizers, with oxides and oxidizers being the primary pollutants. Therefore, whether the air is polluted by pollutants that affect the redox potential, such as oxides and oxidizers, can be determined by whether the redox potential of the moisture in the air is above a predetermined threshold. If the redox potential is above the threshold and the air is determined to be polluted by pollutants, the air pollution caused by pollutants that affect the redox potential can be removed, creating a less polluted environment. The predetermined threshold can be set to a value within the range of 0 to 400 mV, based on the values ​​exemplified for various applications. The predetermined threshold can be set appropriately depending on the intended use of the air management device 1. For example, if the goal is to create an environment similar to an urban indoor environment, the predetermined threshold can be set to 400 mV. This allows the creation of an environment with a level of air pollution less than that of an urban indoor environment. As described above, when the air management device 1 is used to create an optimal living environment for humans and animals, the threshold is set to 200 mV. This allows for the creation of an environment that humans find comfortable. When the air management device 1 is used to create a living environment for plants, the threshold is set to 100 mV. When the air management device 1 is used to create a living environment for microorganisms, the threshold is set to 400 mV. When the air management device 1 is used to suppress spoilage in order to maintain the freshness of food, the threshold is set to 0 mV. In this way, the predetermined threshold can be set to an optimal value depending on the intended use. As described above, the predetermined threshold is used to control the environment to an optimal oxidation-reduction potential according to the intended use of the air management device 1. Therefore, when the oxidation-reduction potential is equal to or greater than this threshold, it indicates a state of contamination with more contaminants that affect the oxidation-reduction potential, such as oxides and oxidizing agents, than the environment intended for use. Therefore, whether the oxidation-reduction potential is equal to or greater than the predetermined threshold can be used to determine whether the air is contaminated with contaminants in the environment intended for use of the air management device 1.If it is determined that the air is contaminated, the reduction unit 4 lowers the oxidation-reduction potential of the moisture in the air, creating an environment that suits the intended use of the air management device 1 and allowing the air to be managed appropriately.

[0062] As described above, the potential measurement unit 3 continuously measures the ORP of the moisture in the air collected by the collection unit 2. Based on the oxidation-reduction potential detected by the potential measurement unit 3, information about air pollution, i.e., information about pollution caused by substances that affect the oxidation-reduction potential and can be detected by the potential measurement unit 3, can be output. This pollution information can be output continuously, periodically, or when a high level of pollution is determined. The pollution level information can be output by the output unit described above, and the output from this output unit can include a display device having a display screen such as a liquid crystal display or a printer capable of outputting printed materials, and can also include sound output. As described above, the pollution information can be output, for example, by indicating the pollution level in stages such as level 1, 2, 3, etc., or strong, medium, weak, or by indicating the pollution level as a percentage from 0 to 100. Visual displays can include text display on a display device or a lamp display. The lamp may illuminate to indicate a relatively high (strong) level of contamination (e.g., an oxidation-reduction potential of 400 mV or higher), yellow for a moderate level of contamination (e.g., an oxidation-reduction potential of approximately 200-400 mV), or green for a low (weak) level of contamination (e.g., an oxidation-reduction potential of 200 mV or lower). The level of contamination may be appropriately set depending on the intended use. Similar to a predetermined threshold, the level of contamination (e.g., strong, medium, or weak) can be determined by an appropriate, optimal value depending on the intended use. The text display may indicate the level of contamination as a numerical value (e.g., level 1 or 2), or as a text display indicating strong, medium, or weak, or as dirty, normal, or clean. The sound output may be audible, or an alarm may be generated when the level of contamination is high.In addition, the output of information regarding contamination by substances that affect the redox potential, which can be detected by the potential measuring unit 3, can be done not only by printed matter, visual display, or sound output from the air management device 1, but also by outputting a signal indicating the degree of contamination to an external device, such as a management device that performs comprehensive management in a facility equipped with multiple air management devices 1.

[0063] Furthermore, as shown in FIG. 3 , the air management device 1 of the embodiment to which the temperature setting unit 7, air temperature measurement unit 8, and oxidation unit 9 are added executes a first control that enables the cooling temperature setting to be increased and a second control that enables the heating temperature setting to be decreased, in accordance with the temperature set by the temperature setting unit 7 and the following threshold values ​​of the oxidation-reduction potential.

[0064] The air management device 1 shown in Figures 3 and 4 further includes a temperature setting unit 7 that sets a first temperature for cooling, which is a relatively high temperature, and a second temperature for heating, which is a relatively low temperature, and an air temperature measuring unit 8 that measures the air temperature. When the redox potential of moisture in the air is equal to or higher than a predetermined first threshold set based on a user's physical sensation so as to provide a good thermal sensation during cooling, and the air temperature measured by the air temperature measuring unit 8 is equal to or higher than the first temperature set by the temperature setting unit 7, the control unit 6 performs a first control operation in which the moisture in the air collected by the collection unit 2 is reduced by the reduction unit 4 to reduce the redox potential of the moisture in the air to the predetermined first threshold and to reduce the air temperature to a lower limit of the first temperature. In the first control operation, the control unit 6 controls the amount of moisture re-dissipated by the diffusion unit 5 to be less than the amount of moisture in the air collected by the collection unit 2, thereby reducing the humidity of the air.

[0065] That is, by lowering the oxidation-reduction potential of moisture in the air to a predetermined first threshold, even if the air temperature is controlled with a relatively high first temperature as the lower limit, in other words, even if the air temperature is controlled to be equal to or higher than the first temperature, dirt is removed from the moisture in the air, and a pleasant cool feeling can be obtained. Furthermore, by lowering the humidity of the air, an even cooler feeling can be obtained. In other words, in summer, for example, a pleasant feeling can be obtained without lowering the air temperature below the first temperature, so the air conditioning temperature setting can be increased.

[0066] The first threshold is set based on a value that can remove contaminants from the air and provide a pleasant cooling sensation. Therefore, the predetermined first threshold is preferably a value within the range of the predetermined threshold for determining contamination (0 to 400 mV) and within a range equivalent to the ORP (skin potential) of human skin. Therefore, the first threshold is preferably a value within the range of 100 mV to 200 mV, for example. If the predetermined first threshold is set to 200 mV, and the oxidation-reduction potential is higher than the first threshold, lowering the oxidation-reduction potential to within the range of human skin potential (100 to 200 mV) can create an air environment that provides a cooling sensation, allowing the air conditioner temperature setting to be increased. Furthermore, if the predetermined first threshold is set to a value lower than 200 mV (e.g., 100 mV), an air environment that provides an even cooler sensation can be created, allowing the air conditioner temperature setting to be increased even higher. Therefore, by executing the first control, energy can be saved during cooling in the summer. Furthermore, in this case, by lowering the oxidation-reduction potential of the air from a state higher than the first threshold to a state lower than the first threshold, contamination caused by substances that affect the oxidation-reduction potential contained in moisture in the air can be removed.

[0067] 3 and 5 , when the redox potential of moisture in the air is less than a predetermined second threshold value set based on bodily sensation so as to provide a sensation of heat during heating and the air temperature measured by the air temperature measuring unit 8 is equal to or lower than the second temperature set by the temperature setting unit 7, the control unit 6 performs second control to oxidize the moisture in the air collected by the collection unit 2 in the oxidation unit 9, thereby increasing the redox potential of the moisture in the air to or above the predetermined second threshold value and raising the air temperature up to the second temperature. In the second control, the control unit 6 controls the amount of re-dissipation by the dissipation unit 5 so that it is greater than the amount of moisture in the air collected by the collection unit 2, thereby increasing the humidity of the air.

[0068] That is, by increasing the oxidation-reduction potential of moisture in the air to a predetermined second threshold or higher, even if the air temperature is controlled with a relatively low second temperature as the upper limit, in other words, even if the air temperature is controlled to be equal to or lower than the second temperature, the moisture in the air becomes contaminated and the user feels hotter. Furthermore, by increasing the humidity of the air, the user feels even hotter. In other words, even if the air temperature is not raised to the second temperature or higher, the user feels hotter in winter, etc., because the user feels hotter.

[0069] The second threshold is set based on a value that allows an increase in the oxidation-reduction potential to produce a sensation of heat. Therefore, the predetermined second threshold is preferably set within the range of the predetermined threshold for contamination detection (0 to 400 mV), higher than the first threshold, and higher than the ORP (skin potential) of human skin, for example, a value in the range of 200 to 400 mV. Specifically, if the predetermined second threshold is set to 200 mV, the highest value in the range of skin potential, increasing the oxidation-reduction potential from a state within the range of human skin potential that produces a cool sensation to a state where the air environment feels hotter, allowing the heating temperature setting to be lowered. To achieve a more intense sensation of heat, the predetermined second threshold is preferably set to a value higher than human skin potential, i.e., a value higher than 200 mV, for example, a value in the range of approximately 200 to 400 mV. In this case, the oxidation-reduction potential is set to a state even higher than the human skin potential, making the temperature feel even hotter and allowing the heating temperature setting to be further lowered. Furthermore, if a value between 300 and 400 is used as the second threshold, the temperature feels even hotter and the heating temperature setting can be further lowered. Therefore, by executing the second control, energy savings can be achieved during heating in winter.

[0070] As explained above, the air management device 1 explained based on Figures 3, 4, and 5 can remove contaminants from the air, and can increase the cooling temperature setting in summer so that the air feels cool, and can decrease the heating temperature setting in winter so that the air feels hot. Therefore, by executing the first control and the second control, energy savings can be achieved throughout the year.

[0071] Since the air management device 1 is intended to remove airborne contaminants, the first and second thresholds are set to values ​​within a predetermined threshold range for determining whether the air is contaminated by moisture. The predetermined threshold is preferably set to a value within a range of 0 to 400 mV based on the airborne contaminants in the environment in which the air management device 1 is intended to be used, depending on the intended use. The first threshold is preferably set to a low value of 200 mV or less within the range of human skin potential, such as 200 mV, a value within a range of 100 to 200 mV, or 100 mV. In any case, by setting the oxidation-reduction potential within the range of human skin potential, a cool sensation can be achieved. The second threshold is preferably set to a value within the predetermined threshold range, such as a value within the range of human skin potential or higher than the skin potential. For example, a value of 200 mV, the highest value within the range of skin potential, or a value higher than the skin potential can be set to achieve a hot sensation. As described above, the predetermined threshold, the first threshold, and the second threshold may use a common value (e.g., 200 mV). Furthermore, the predetermined threshold is set appropriately depending on the intended use of the air management device 1. The first threshold is set appropriately for the purpose of lowering the sensible temperature during cooling, and the second threshold is set appropriately for the purpose of raising the sensible temperature during heating. Therefore, the predetermined threshold, the first threshold, and the second threshold may each use a different value.

The control unit 6 outputs information about air pollution based on the oxidation-reduction potential of the moisture in the air measured by the potential measuring unit 3. If the redox potential of the moisture in the air is equal to or greater than a predetermined threshold and the air is determined to be polluted, the moisture in the air collected by the collection unit 2 is reduced in the reduction unit 4 to remove contaminants, and then re-dissipated into the air from the diffusion unit 5. If the redox potential of the moisture in the air is less than the predetermined threshold and the air is determined to be unpolluted, the moisture in the air collected by the collection unit 2 is re-dissipated into the air from the diffusion unit 5 as is. Furthermore, if the redox potential of the moisture in the air is equal to or greater than a predetermined first threshold set based on subjective sensation and the air temperature measured by the air temperature measurement unit 8 is equal to or greater than a first temperature set by the temperature setting unit 7, the moisture in the air collected by the collection unit 2 is reduced in the reduction unit 4 to reduce the redox potential of the moisture in the air to below the predetermined first threshold, the air temperature is reduced to a first temperature as a lower limit, and the amount of re-dissipation by the diffusion unit 5 is controlled to be less than the amount of moisture in the air collected by the collection unit 2, thereby performing a first control to reduce the humidity of the air.

If the redox potential of the moisture in the air is equal to or greater than a predetermined threshold and it is determined that the air is polluted, the moisture in the air collected by the collection unit 2 is reduced in the reduction unit 4 to remove the contaminants, and then re-dissipated into the air from the diffusion unit 5. If the redox potential of the moisture in the air is less than the predetermined threshold and it is determined that the air is not polluted, the moisture in the air collected by the collection unit 2 is re-dissipated into the air from the diffusion unit 5 as is. Furthermore, if the redox potential of the moisture in the air is less than a predetermined second threshold set based on bodily sensation and the air temperature measured by the air temperature measurement unit 7 is equal to or less than a second temperature set by the temperature setting unit 8, the moisture in the air collected by the collection unit 2 is oxidized in the oxidation unit 9 to increase the redox potential of the moisture in the air to equal to or greater than the predetermined second threshold, the air temperature is raised with the second temperature as an upper limit, and the amount of re-dissipation by the diffusion unit 5 is controlled to be greater than the amount of moisture in the air collected by the collection unit 2, thereby performing a second control to increase the humidity of the air.

[0074] The air management device 1 shown in FIG. 3 as described above comprises a collection unit 2 that collects moisture in the air, a potential measurement unit 3 that measures the redox potential of the moisture in the air collected by the collection unit 2, a reduction unit 4 that reduces the moisture in the air collected by the collection unit 2 to lower the redox potential of the moisture in the air, a diffusion unit 5 that re-diffuses the moisture in the air collected by the collection unit 2 into the air, a temperature setting unit 7 that sets a first temperature for cooling which is a relatively high temperature and a second temperature for heating which is a relatively low temperature, an air temperature measurement unit 8 that measures the temperature of the air, and a temperature setting unit 9 that sets a temperature setting unit 10 for setting the temperature setting unit 11 for setting the temperature setting unit 12 for setting the temperature setting unit 13 for setting the temperature setting unit 14 for setting the temperature setting unit 15 for setting the temperature setting unit 16 for setting the temperature setting unit 17 for setting the temperature setting unit 18 for setting the temperature setting unit 19 for setting the temperature setting unit 20 for setting the temperature setting unit 19 ... and a control unit 6 that performs control based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3, the temperature set by the temperature setting unit 7, and the temperature of the air measured by the air temperature measurement unit 8. The control unit 6 outputs information about air pollution based on the oxidation-reduction potential of the moisture in the air measured by the potential measurement unit 3, and when the oxidation-reduction potential of the moisture in the air is equal to or greater than a predetermined threshold and the air is determined to be polluted, the control unit 6 reduces the moisture in the air collected by the collection unit 2. After the contamination is removed by reduction in the source unit 4, the moisture is re-dissipated into the air from the diffusion unit 5. If the redox potential of the moisture in the air is less than a predetermined threshold and it is determined that the air is not contaminated, the moisture in the air recovered by the recovery unit 2 is re-dissipated into the air from the diffusion unit 5 as it is. Furthermore, if the redox potential of the moisture in the air is equal to or greater than a predetermined first threshold set based on bodily sensation and the temperature of the air measured by the air temperature measurement unit 8 is equal to or greater than a first temperature set by the temperature setting unit 7, the moisture in the air recovered by the recovery unit 2 is reduced in the reduction unit 4, and the moisture in the air is a first control for reducing the humidity of the air by reducing the redox potential of the moisture in the air to less than a predetermined first threshold, reducing the temperature of the air to a first temperature as a lower limit, and controlling the amount of re-emission by the diffusing unit 5 to be less than the amount of moisture in the air recovered by the recovering unit 2; and further, when the redox potential of the moisture in the air is less than a predetermined second threshold set based on subjective sensation and the temperature of the air measured by the air temperature measuring unit 7 is equal to or lower than the second temperature set by the temperature setting unit 8, oxidizing the moisture in the air recovered by the recovering unit 2 in the oxidizing unit 9;A second control is performed to increase the oxidation-reduction potential of moisture in the air to a predetermined second threshold value or more, to increase the temperature of the air up to the second temperature, and to increase the humidity of the air by controlling the amount of moisture re-emitted by the diffusing unit 5 to be greater than the amount of moisture in the air recovered by the recovering unit 2.
